Pengaruh Pemanfaatan Semen Grouting StrongGrout G70 Sebagai Filler terhadap Karakteristik dan Durabilitas Campuran AC-WC
type: item
description: Transportation plays an important role in supporting mobility which is highly dependent on the quality of road pavement. Premature damage to the asphalt surface layer often occurs due to increased traffic volume, excessive loads, and low water resistance. This study aims to analyze the effect of using StrongGrout G70 grouting cement as a filler on the Marshall characteristics and durability of the Asphalt Concrete–Wearing Course (AC-WC) mixture, as well as determining the optimum filler content. The research method uses an experimental approach with variations in StrongGrout G70 content of 0%, 0.5%, 1%, 1.5%, and 2% of the total aggregate weight. The mixture characteristics were tested using the Marshall method, while durability was evaluated through the Residual Strength Index (RSI), First Durability Index (FDI), and Second Durability Index (IDK), according to the 2025 General Bina Marga Specifications. The test results showed that stability increased from 1351.94 kg (0%) to 1615.55 kg (2%), flow decreased from 3.10 mm to 2.50 mm, VIM decreased from 4.28% to 3.21%, VFA increased from 73.84% to 79.10%, VMA decreased from 16.20% to 15.26%, and Marshall Quotient increased from 439.26 kg/mm to 648.64 kg/mm. In durability, the IKS variation of 2% reached 96.70% (24 hours), 94.35% (36 hours), 91.54% (48 hours), 88.94% (60 hours), and 83.54% (72 hours), higher than 0% which was only 76.95% at 72 hours. The IDP value of 2% ranged from 0.14%–0.23% and the IDK Sa decreased from 98.92% to 92.43% with a strength loss of 1.08%–7.57%. The results showed that the use of StrongGrout G70 at 2% provided the best performance on the stability and durability of the AC-WC mixture.

Model Probabilistik Penentuan Bobot Biaya Tenaga Kerja, Material, dan Peralatan pada Proyek Gedung Menggunakan Simulasi Monte Carlo
type: item
description: The construction industry is characterized by high cost uncertainty due to material price fluctuations, labor productivity variability, design changes, and market dynamics. At the conceptual estimating stage, project cost structures are commonly determined using deterministic approaches based on historical averages, which fail to adequately represent real-world variability. This study aims to develop a probabilistic model for determining the weight of labor, material, and equipment costs in three-story building projects using Monte Carlo simulation based on empirical data from 16 completed projects. The methodology includes descriptive statistical analysis to obtain distribution parameters, goodness-of-fit testing for selecting appropriate probability distributions, and a 1,000-iteration Monte Carlo simulation applied to a normalized composite cost structure index. The results indicate average cost proportions of 40.57% for labor, 34.53% for materials, and 11.45% for equipment, with substantial variation across projects. The simulation produced a mean composite index value of 116.98 with a P10–P90 interval ranging from 74.25 to 157.30, indicating moderate to high cost uncertainty. The proposed model is recommended as a confidence-level–based conceptual estimating baseline to enhance budget planning accuracy and cost risk management in low-rise building projects.

Simulasi dan Pemetaan Banjir 1D dan 2D di Wilayah Hilir Sub-Das Lambidaro Menggunakan HEC-RAS
type: item
description: Flooding is one of the most destructive natural disasters and frequently occurs in densely populated residential areas located in lowland regions. Lowland areas with high population density generally have low infiltration capacity and high surface runoff, causing flooding to occur repeatedly during rainfall events. Palembang City is predominantly situated in lowland areas and has a relatively high population density. The downstream area of the Lambidaro sub-watershed is one of the densely populated lowland regions in Palembang City, making it highly vulnerable to flooding during rainfall events with certain intensities. This study aims to simulate and map flooding in the downstream area of the Lambidaro sub-watershed using the HEC-RAS program, in which flood discharge was first analyzed using the Nakayasu Synthetic Unit Hydrograph (HSS) method. Based on the flood analysis using the Nakayasu Synthetic Unit Hydrograph (HSS) method, a simulated peak flood discharge of 57.17 m³/s was obtained from the maximum effective rainfall during the observation period from January 1, 2026 to April 9, 2026, with an effective rainfall value of 43.376 mm. In this study, rainfall data were obtained from NASA POWER Data Access Viewer (DAV) satellite data, which were utilized as satellite-based rainfall estimation data for daily hydrological analysis while considering the limitations of the data and the need for verification using local observational records. Based on the 1D and 2D simulations using the HEC-RAS program, flooding in the downstream area of the Lambidaro sub-watershed was predominantly concentrated in areas surrounding the Lambidaro River, with floodwater depths reaching up to 0.73 meters.

Determinasi Hambatan Penerapan Konsep Green Building pada Proyek Konstruksi di Indonesia Timur
type: item
description: Global climate change encourages the implementation of the green building concept as a strategy to reduce greenhouse gas emissions in the construction sector. However, its implementation in the Eastern Indonesia region still faces various obstacles. This study aims to analyze the influence of barrier factors on the level of barriers to the implementation of the green building concept and to identify the most dominant factor. The approach used is quantitative with an explanatory research design. Data were collected through questionnaires from 94 respondents consisting of contractors and consultants in Eastern Indonesia. The analysis was conducted using the Structural Equation Modeling–Partial Least Square (SEM-PLS) method. The results show that technical, educational, economic, and technological factors have a significant effect on the level of barriers to green building implementation, while regulatory factors do not have a significant effect. The economic factor becomes the most dominant barrier, indicated by the highest path coefficient value compared to other variables. These findings indicate that the aspects of initial investment costs and limited financing remain the main considerations in the implementation of green building in the region. Academically, this study enriches the study of barriers to green building implementation in Eastern Indonesia, which is still limited, while also strengthening the use of SEM-PLS in structural model analysis in sustainable construction studies.

Pengaruh Tingkat Penambahan Fly Ash terhadap Kinerja Mekanik Beton
type: item
description: The increasing demand for concrete in infrastructure development leads to higher cement consumption, while cement production is a significant source of carbon dioxide emissions. The use of fly ash as a partial cement replacement offers an alternative to produce more efficient and environmentally friendly concrete. This study aims to analyze the effect of fly ash substitution on workability and compressive strength, determine the optimum technical dosage, and evaluate simple cost efficiency. The research employed a laboratory experimental method with fly ash variations of 0%, 10%, and 20% by weight of cement. Tests were conducted on slump and 14-day compressive strength using three cylindrical specimens for each variation. The 28-day compressive strength was estimated based on a 0.73 strength development factor from the 14-day results. The results show that slump decreased from 13.0 cm in normal concrete to 11.0 cm at 10% fly ash and 10.5 cm at 20% fly ash. The average 14-day compressive strengths for 0%, 10%, and 20% variations were 40.481 MPa, 40.953 MPa, and 35.858 MPa, respectively, with estimated 28-day strengths of 55.454 MPa, 56.100 MPa, and 49.120 MPa. The 10% fly ash variation produced the highest compressive strength, increasing by 1.17% compared to normal concrete. Cost analysis indicates savings of 3.60% for 10% fly ash and 7.20% for 20% fly ash. Therefore, 10% fly ash is recommended as the optimum technical proportion, while 20% fly ash is more suitable for cost efficiency but should be applied cautiously in structural applications.

Probabilistik Durasi Proyek Konstruksi Menggunakan Integrasi Critical Path Method dan Simulasi Monte Carlo pada Pembangunan Gedung Ruang Kelas Belajar MAN 4 Kampar
type: item
description: Construction project scheduling commonly applies a deterministic approach using the Critical Path Method (CPM) to determine critical activities and project duration. However, this approach often fails to represent the uncertainty of activity durations that frequently occur during project implementation. Such uncertainty may cause deviations from the planned schedule and increase the risk of project delays. Therefore, a probabilistic approach is required to analyze project duration variability more realistically. This study aims to analyze the probability of construction project completion time by integrating the Critical Path Method and Monte Carlo simulation. The case study was conducted on the construction project of the MAN 4 Kampar classroom building with a planned duration of 244 days. The analysis began with developing a project network and identifying the critical path using CPM. The variability of activity durations on the critical path was then modeled using a triangular probability distribution and analyzed through Monte Carlo simulation using Oracle Crystal Ball with 1000 iterations. The simulation results indicate that the project duration follows a probabilistic distribution ranging from 199.13 days to 214.99 days. The project duration at the P50 probability level is 207.58 days, while the P80 and P90 levels are 209.76 days and 210.76 days, respectively. These findings demonstrate that the probabilistic approach provides a more comprehensive representation of project duration variability compared with the deterministic approach. Therefore, the integration of CPM and Monte Carlo simulation is recommended as a probabilistic analysis method in the planning and control of construction project schedules to anticipate project duration uncertainty.

Implementasi Project Management Body of Knowledge (PMBOK) pada Pembangunan Fasilitas Sisi Udara Bandar Udara Mentawai Baru di Daerah 3T Kepulauan Mentawai
type: item
description: In disaster situations, airports serve as vital infrastructure for evacuation and logistics distribution due to their ability to operate quickly, safely, and relatively independently from disruptions to land and sea transportation. Limited sea and air transportation fleets in the Mentawai Islands result in minimal crossing and flight services. To address these limitations, the government developed the New Mentawai Airport as a replacement for Rokot Airport. This condition highlights the importance of evaluating project management implementation to ensure the success of airside facility development in remote and underdeveloped regions. This study aims to identify Project Management Body of Knowledge (PMBOK) factors, determine the level of PMBOK implementation, and analyze the most influential PMBOK factors affecting project success in the construction of airside facilities at New Mentawai Airport. A quantitative research approach was employed by distributing questionnaires to all personnel involved in the project, including the project owner, construction management, and contractors. The collected data were analyzed using validity and reliability tests, descriptive analysis, classical assumption tests, and regression analysis. The results indicate that thirteen PMBOK factors were implemented at a very high level, covering project integration, scope, time, cost, quality, human resources, communication, risk, procurement, occupational health and safety, environmental management, financial management, and claims management. Partially, project risk management and project cost management were identified as the most significant factors influencing project success. It is recommended that risk management and cost control be strengthened from the planning stage through project execution to improve the success of infrastructure development projects in remote areas.

Evaluasi Kapasitas Drainase di Jalan Mayjen HM Ryacudu Kota Palembang Menggunakan Pemodelan EPA SWMM
type: item
description: Flooding is a natural disaster that significantly disrupts human activities. The occurrence of flooding is closely related to drainage problems, as rainwater runoff requires a drainage system capable of collecting and conveying runoff water to drainage outlets. Jalan Mayjen HM Ryacudu in Palembang City frequently experiences flooding, even though the existing drainage system has an outlet that directly discharges into the Musi River. This study evaluated the drainage capacity along Jalan Mayjen HM Ryacudu due to the persistent flooding occurring in the area. The purpose of this evaluation was to determine an appropriate drainage capacity within the study area as a mitigation measure against flooding. The evaluation was conducted by simulating rainfall runoff using the EPA SWMM program. The results of the EPA SWMM modeling indicate that the existing drainage capacity is still unable to optimally accommodate and convey rainwater runoff, resulting in inundation at several locations along Jalan Mayjen HM Ryacudu. The mitigation scenario through drainage dimension optimization showed that modifying the drainage channels to a uniform size of 1.2 × 1.2 meters was able to eliminate flooding indications in the EPA SWMM simulation results.

Prediksi Progres Aktual Proyek Konstruksi pada Tahap Awal Durasi Menggunakan Earned Value Management
type: item
description: This study is motivated by the limitations of previous research, which has predominantly focused on project performance evaluation during the execution or completion stages, while the capability of Earned Value Management (EVM) to predict project progress in the early phase remains underexplored. The objective of this study is to analyze and predict the actual progress performance of construction projects during the early stage of project duration. The research adopts a quantitative descriptive-analytical approach by utilizing key EVM indicators, namely Planned Value (PV), Earned Value (EV), and Schedule Performance Index (SPI), along with the development of a predictive model based on cumulative average performance (SPI_avg). The study was conducted on three public building construction projects with durations ranging from 52 to 68 weeks, with evaluation points set at 10% to 50% of the total project duration. The results indicate that the accuracy of the prediction model is highly influenced by the stability of SPI values during the early stage. Projects with stable performance produce lower prediction errors (approximately 20–45%), whereas projects with high performance fluctuations exhibit significantly higher errors (greater than 60%). Projects experiencing extreme acceleration in the early phase tend to produce overestimated predictions due to bias in SPI values. This study recommends the use of more adaptive prediction models, as well as the integration of complementary methods such as Earned Schedule, to improve prediction accuracy under fluctuating project conditions.

Pengaruh Metode Analisis Stabilitas Lereng 3D terhadap Faktor Keamanan dan Kebutuhan Perkuatan pada Timbunan di Atas Tanah Lunak
type: item
description: Three-dimensional (3D) slope stability analysis is increasingly used in geotechnical planning because it is able to represent landslide conditions more closely than two-dimensional (2D) analysis. Differences in results between analytical methods and software have the potential to result in different reinforcement requirements. This study aims to compare the three-dimensional slope safety factor values obtained using the analytical method with the Hovland formula and Plaxis LE software and evaluate their influence on the need for geotextile reinforcement. The analysis was conducted using the three-dimensional Limit Equilibrium Method (LEM) on several variations in width, height, slope, and the ratio of the length of the landslide plane to the height of the embankment. The results showed that the 3D safety factor values ranged from 0.461 to 1.512. A comparison between the safety factors obtained from the analysis and the Hovland method showed that the ratio varied between 0.256 and 1.618, indicating a considerable difference in safety factor values between the PLAXIS LE 3D results and the Hovland method. The required geotextile reinforcement ranged from 0 to 37 layers and increased with increasing ls/H values, embankment width, and embankment height. The results of the study show that the selection of the three-dimensional slope stability analysis method influences the safety factor and the need for geotextile reinforcement, so it needs to be considered in the geotechnical planning process.

Optimalisasi Waktu Proyek Pembangunan Rumah Susun dengan Metode PDM dan PERT
type: item
description: The construction of the Polda Kaltim apartment building requires systematic time control because the project experienced a delay from the initial contract duration of 240 calendar days. The delay was mainly caused by material distribution constraints, limited workforce availability, and the lack of optimal periodic evaluation between the planned schedule and field realization. This study aims to analyze the critical path and the probability of achieving the evaluated project duration target of 270 calendar days using the Precedence Diagram Method (PDM) and Program Evaluation and Review Technique (PERT). The research data were obtained through literature review, observation, interviews, project documents, and duration-estimation questionnaires completed by 30 respondents. The PDM method was used to identify activity dependencies and critical paths, while the PERT method was applied to calculate expected time, standard deviation, variance, and project completion probability. The results show that the expected project duration is 267 days with a standard deviation of 3.51 days. The evaluated target duration of 270 days has an achievement probability of 80%. In addition, 59 critical activities were used in the PERT variance calculation and require intensive monitoring. Therefore, the integration of PDM and PERT can be used as a scheduling tool to evaluate target-duration achievement, identify critical activities, and formulate more measurable project time-control strategies.

Analisis Distribusi Biaya Proyek Menggunakan Pareto Untuk Mengidentifikasi Cost Drivers pada Proyek Revitalisasi Sekolah Rawan Banjir
type: item
description: The revitalization of school buildings in flood-prone areas has become a significant challenge in managing educational infrastructure in Indonesia. The general problem frequently encountered is the high construction cost caused by the need to adapt buildings to flood risks, while public project budgets are required to remain efficient and accountable. In the revitalization project of SDN Sukamanah 02 Jonggol, the building’s location below the surrounding road and drainage elevation resulted in recurring flooding that damaged school facilities and disrupted educational activities. The specific problem addressed in this study is the lack of information regarding project cost distribution and dominant work items (cost drivers) contributing the largest proportion of the total revitalization cost. Therefore, this study aims to analyze the cost distribution of the SDN Sukamanah 02 revitalization project using Pareto Analysis to identify dominant work items as a basis for project cost control. This research employed a descriptive quantitative method with a case study approach. The data were obtained from the Bill of Quantities (BoQ), technical specifications, field observations, and project documentation of the SDN Sukamanah 02 revitalization project. The analysis was conducted using the Pareto method by ranking work items from the highest to the lowest cost and calculating their cumulative percentage contribution to the total project cost. The results indicate that five dominant work items, namely bitumen roof covering, soil embankment, fabricated doors and windows, granite flooring, and PVC ceiling, contributed approximately 57.9% of the total project cost. These findings demonstrate that most project costs were concentrated on environmental adaptation works and architectural components. This study recommends the application of Pareto Analysis as a basis for cost control and efficiency evaluation priorities in school revitalization projects located in flood-prone areas.

Analisis Bangkitan Pergerakan Penduduk Berdasarkan Karakteristik Rumah Tangga di Kelurahan Morokrembangan Kota Surabaya
type: item
description: The ongoing population growth leads to high levels of community activity and mobility, especially in densely populated urban areas. Morokrembangan Village in Surabaya City is an area with significant traffic, supported by dense settlements and strategic access via Jalan Gresik, a connecting route between Surabaya and Gresik. To date, no study has specifically identified the magnitude of population activity by household characteristics in Morokrembangan Village, nor its relationship to population movement patterns supporting daily activities. Therefore, this study aims to analyze the characteristics and population movements based on household conditions. The method used is quantitative with probability sampling and simple random sampling techniques. Data analysis was carried out using validity and reliability, correlation, multiple linear regression, coefficient of determination, F and t tests, and SPSS Statistics 26. The results showed that the number of family members, trip purpose, and trip destination significantly influence population movement. Travel activities are dominated by work purposes, with the highest travel time in the morning, and the majority of movements occur in the North Surabaya area. Regression results indicate that the number of family members, trip purpose, and trip destination have a positive direction of influence on daily household trips, with regression coefficients of 0.511, 0.857, and 0.139, respectively. These findings can inform more effective and sustainable transportation planning and infrastructure development in the region.

Analisis Koordinasi Antar Pihak pada Proyek Konstruksi Bangunan Gedung Melalui Studi Literatur
type: item
description: Building construction projects involve various parties with different roles, responsibilities, and interests, requiring effective coordination to achieve the established time, cost, and quality targets. The complexity of building construction projects demands the integration of various activities, resources, and decision-making processes among the parties involved. Lack of coordination can lead to various issues such as work delays, communication errors, conflicts between parties, and discrepancies between project outcomes and planning. This research aims to analyze coordination among parties in building construction projects through a literature study approach. The research method used is a literature study with a descriptive qualitative approach through the stages of problem identification, literature search, literature selection, content analysis, and synthesis of research results based on relevant national and international scientific articles. The research results show that the effectiveness of coordination is influenced by factors such as communication, information exchange, stakeholder involvement, decision-making, and information management systems. Coordination obstacles found include delayed information, lack of communication, unclear task distribution, and differing objectives among parties. This study recommends the implementation of regular coordination meetings, increased stakeholder involvement, and the application of an integrated information system to enhance the effectiveness of building construction project coordination.

Analisis Risiko Proyek Konstruksi Jalan Tol Menggunakan Metode Risk Matrix dan Relative Importance Index (RII)
type: item
description: Toll road construction projects are characterized by high complexity and uncertainty due to the involvement of multiple stakeholders, regulatory constraints, and dynamic site conditions, which often lead to delays and cost overruns. Despite extensive studies on construction risk, existing approaches tend to apply fragmented methods that fail to simultaneously capture risk magnitude and prioritization in an integrated manner. This study aims to develop a comprehensive risk evaluation framework by integrating the Risk Matrix and Relative Importance Index (RII) to identify, assess, and prioritize risks in toll road construction projects. A quantitative approach was employed using primary data collected through structured questionnaires distributed via Google Form to project stakeholders between January and February 2026. The identified risk variables were analyzed by calculating risk scores based on probability and impact, followed by RII to determine risk prioritization. The results were further visualized using a risk heatmap to enhance interpretability. The findings reveal that the most critical risks are predominantly associated with non-technical factors, particularly land acquisition delays, land readiness issues, and inter-agency coordination. These risks consistently rank highest in both risk matrix and RII analyses, indicating strong agreement between risk severity and stakeholder perception. Additionally, operational risks such as construction delays and traffic disruptions also contribute significantly to project performance degradation. This study contributes by proposing an integrated and visually enhanced risk assessment framework that bridges the gap between quantitative evaluation and practical decision-making. The proposed approach provides a more comprehensive understanding of risk distribution and prioritization, offering practical implications for improving risk management strategies in large-scale infrastructure projects, particularly in developing…

Optimasi Fasad Bangunan untuk Efisiensi Energi Berdasarkan Analisis OTTV pada Ruang Dosen Politeknik Negeri Sriwijaya
type: item
description: Building facade optimization plays an essential role in improving the energy efficiency of buildings, particularly in tropical regions such as Indonesia, which experience high solar radiation intensity. Educational institution buildings, such as the Lecturer Room of the D-IV Building Architecture Program at Politeknik Negeri Sriwijaya, Keramasan Campus, represent one of the building types with high energy demand for thermal comfort and lighting. The urgency of this research lies in the need for façade design strategies that can reduce cooling loads without compromising thermal and visual comfort, while also complying with energy efficiency standards through the calculation of the Overall Thermal Transfer Value (OTTV). This study aims to examine and optimize the building facade design based on OTTV values in accordance with SNI 03-6389-2011 and the Ministry of Energy and Mineral Resources Regulation (Permen ESDM) No. 02/2021. The research employs a quantitative approach consisting of field surveys, physical data collection of the building, thermal modeling, and simulation of façade optimization through the combination of shading devices and low-e glass. The results show that the existing façade design has an OTTV value of 43.21 W/m², exceeding the maximum limit of 35 W/m². After optimization through the application of horizontal shading devices and the use of low-e glass, the OTTV value decreased to 32.87 W/m², meeting the energy efficiency standard. This research provides recommendations for energy-efficient facade design and serves as a reference for designing educational buildings in hot-humid tropical climates. The findings are expected to contribute to the development of sustainable architectural design practices within campus environments.

Studi Eksperimental Pengaruh Variasi Serat Ilalang terhadap Kuat Tekan Beton Mutu K-150
type: item
description: Concrete is a widely used construction material due to its high compressive strength and ease of construction. However, concrete is brittle and has low tensile strength, making it prone to cracking. One approach that can be investigated to modify concrete characteristics is the addition of natural fibers to the concrete mixture. This study aims to analyze the effect of adding thatch fibers on the compressive strength of K-150 grade concrete. The study was conducted experimentally using cube-shaped test specimens measuring 15x15x15 cm. The variations in the addition of thatch fibers used were 0%, 2.5%, 5%, and 10% of the cement weight. Compressive strength testing was carried out at 7 days, 14 days, and 28 days. The results showed that normal concrete without thatch fibers produced the highest compressive strength of 16.44 MPa at 28 days. The addition of 2.5% thatch fibers still produced a compressive strength that was relatively close to normal concrete, namely 16.31 MPa. However, the addition of 5% and 10% fiber resulted in a significant decrease in compressive strength to 7.11 MPa and 2.22 MPa, respectively. The decrease in concrete compressive strength was presumably influenced by increased porosity, decreased workability, and less homogeneous fiber distribution in the concrete mixture. Based on the compressive strength results, the addition of thatch fiber in small amounts, particularly 2.5% of cement weight, can still be considered as a concrete additive. However, its use needs to be limited because higher fiber contents significantly reduce the compressive strength of concrete.

Identifikasi dan Pengelolaan Risiko Lokasi Proyek di Wilayah Bali: Pendekatan Kualitatif Melalui Wawancara Mendalam dengan Para Manajer Proyek
type: item
description: This study aims to explore the identification and management of location-based risks in construction projects in Bali through a qualitative approach using in-depth interviews with ten experienced project managers. As an internationally recognized tourism destination, Bali possesses complex and multidimensional risk characteristics encompassing physical-geographical, socio-cultural-customary, and regulatory-permitting aspects. The research employed a phenomenological study design to understand the practical experiences of project managers in dealing with location-related risks directly in the field. The findings reveal three primary clusters of location risks consistently encountered by project managers, namely physical-geographical risks, socio-cultural-customary risks, and regulatory and permitting risks. Socio-cultural risks rooted in local customary systems such as desa pakraman, awig-awig, and the Tri Hita Karana concept emerged as the main distinguishing factors compared to other regions in Indonesia, as they directly affect project schedules, costs, and design processes. In addition, dynamic regulations and Bali’s disaster-prone geographical conditions further increase the complexity of construction project management. The risk management strategies implemented by project managers are adaptive and contextual, emphasizing the involvement of customary communities from the pre-construction stage, periodic updates of the risk register, and the application of combined avoidance, mitigation, and acceptance strategies based on the characteristics of each risk. This study contributes to the development of a locality-based risk management framework relevant to construction projects in tourism areas across Indonesia while highlighting the importance of integrating local cultural aspects into modern risk management practices.

Evaluasi Kesesuaian Desain Rumah Tinggal Dua Lantai terhadap Kondisi Iklim dan Kerawanan Gempa di Pulau Lombok
type: item
description: Lombok Island has a humid tropical climate and a high risk of earthquakes due to tectonic activity; consequently, residential design must take into account aspects of thermal comfort and structural resilience. This study aims to evaluate the suitability of the architectural and structural design of a two-storey residential house for three occupants in relation to local environmental conditions. The method used is descriptive evaluation with a case study approach by reviewing design drawings, including floor plans, elevations, sections, and structural details, which were then compared with the principles of tropical house design and general provisions for earthquake-resistant buildings. The results of the study indicate that the spatial layout meets the functional needs of a small family with a clear division between private and public zones, whilst applying tropical architectural principles through the use of pitched roofs and natural openings to enhance thermal comfort. However, from a structural perspective, the details of the foundation, columns, beams, and structural connections are not yet sufficiently explained, thus requiring further technical verification based on earthquake-resistant building provisions. Consequently, whilst this house design meets functional and climatic requirements, it does not yet fully comply with earthquake-resistant building principles, thus requiring structural design optimisation.

Analisis Karakteristik Tanah Dasar pada Ruas Jalan Maduran Kabupaten Lamongan Berdasarkan Uji CBR dan Direct Shear
type: item
description: Road damage on several road sections in Lamongan Regency may be influenced by unstable subgrade conditions, particularly in areas with high water content and clayey soil characteristics. Subgrade soil with high plasticity and low bearing capacity can reduce pavement performance; therefore, laboratory testing is required to evaluate its physical and mechanical properties. This study aims to analyze the characteristics of subgrade soil on the Maduran road section in Lamongan Regency based on water content, Atterberg limits, California Bearing Ratio (CBR), and direct shear parameters. Soil samples were collected from the study location and tested in the laboratory to determine the physical and mechanical properties of the subgrade. The test results showed a water content of 16.66%, liquid limit of 35.82%, plastic limit of 1.21%, plasticity index of 34.61%, CBR value of 6.80%, shear strength of 0.72 kg/cm², internal friction angle of 15.03°, and cohesion of 0.0340 kg/cm². Based on the plasticity index, the soil is classified as high-plasticity clay, while the CBR value falls into the poor to fair category for subgrade material. Therefore, drainage improvement, proper compaction, and subgrade stabilization are recommended before pavement rehabilitation is carried out.

Karakteristik Beton dengan Variasi Diameter Serat Bambu terhadap Kuat Tarik Belah Beton
type: item
description: Concrete is a construction material with high compressive strength; however, it has a relatively low tensile strength, which makes it susceptible to cracking. One approach to improving the tensile strength of concrete is the addition of natural fibers, such as bamboo fibers, which are environmentally friendly, lightweight, and easily obtained. Variations in bamboo fiber diameter may influence the bonding between the fibers and the concrete matrix, thereby affecting the splitting tensile strength of concrete. This study aims to analyze the effect of bamboo fiber diameter variations on the splitting tensile strength of concrete and to determine the fiber diameter that produces the highest average splitting tensile strength. The research method used is an experimental laboratory method with a designed concrete strength of f’c 25 MPa. The bamboo fiber diameters used in this study were 2 mm, 4 mm, and 6 mm. Cylindrical specimens with dimensions of 100 mm × 200 mm were used and tested at the ages of 7, 14, 21, and 28 days. The results of this study indicate that the addition of bamboo fibers improves the splitting tensile strength of concrete. At 28 days, the control concrete had a splitting tensile strength of 2.65 MPa, while concrete with bamboo fiber additions showed values of 2.77 MPa for 2 mm diameter, 3.24 MPa for 4 mm diameter, and 2.94 MPa for 6 mm diameter. Based on the average test results, the 4 mm fiber diameter showed the highest splitting tensile strength compared with the 2 mm and 6 mm variations. This study recommends the use of 4 mm bamboo fiber as an environmentally friendly alternative additive to improve the tensile performance of concrete and support sustainable construction development.

Studi Evaluasi Ketersediaan Lahan Parkir dalam Menentukan Kapasitas Kendaraan di Pasar Tradisional Sendangrejo Ngimbang
type: item
description: Sendangrejo Ngimbang Market is one of the traditional markets with relatively high activity in Ngimbang District. Market visitors come not only from the surrounding area but also from other districts, such as Sambeng, Bluluk, and Sukorame. These activities generate a demand for parking space that needs to be evaluated to prevent disruption to traffic flow around the market area. This study aims to evaluate the availability of parking space in determining vehicle capacity at Sendangrejo Ngimbang Traditional Market. A quantitative method was applied through a field survey conducted over 7 observation days on January 4, 6, 11, 13, 22, 25, and 31, 2026, from 07:00 to 12:00 WIB. The analyzed parameters included parking accumulation, parking duration, parking volume, parking index, and parking turnover rate. The results showed that the highest motorcycle parking accumulation during the observation period was 66 vehicles out of a capacity of 165 vehicles, while the highest car parking accumulation was 4 vehicles out of a capacity of 4 vehicles. The highest motorcycle parking index was 40.00%, whereas the highest car parking index reached 100.00% on one observation day. Therefore, motorcycle parking space remains sufficient, while car parking reaches full capacity at certain times. Accordingly, better car parking arrangement, separation of parking areas by vehicle type, and control of on-street parking are required to prevent market activities from disrupting surrounding traffic flow.

Pengaruh Penggunaan Minyak Goreng Bekas pada Campuran Asphalt AC-BC
type: item
description: This study was conducted to investigate the effect of using waste cooking oil as a partial substitute for asphalt on the Marshall characteristics of Asphalt Concrete – Binder Course (AC-BC) mixtures. The research employed an experimental laboratory method using the Marshall test in accordance with the 2018 General Specifications of Bina Marga. The variations of waste cooking oil used were 1.5%, 2.0%, 2.5%, 3.0%, and 3.5% by weight of asphalt, with an optimum asphalt content of 5.3%. The parameters analyzed included Void in Mix (VIM), Void in Mineral Aggregate (VMA), Voids Filled with Bitumen (VFB), stability, and flow. The results showed that waste cooking oil contents ranging from 1.5% to 3.0% satisfied the requirements of the 2018 Bina Marga Specifications, while the 3.5% variation failed to meet the flow requirement, producing a value of 4.20 mm, which exceeded the specified limit of 2–4 mm. The VIM values ranged from 3.51% to 3.76%, the VMA values ranged from 14.26% to 14.48%, and the VFB values ranged from 74.19% to 75.38%. The highest stability value was obtained at a waste cooking oil content of 1.5%, reaching 1412 kg. Meanwhile, the flow values tended to increase with increasing waste cooking oil content, indicating that the mixture became more flexible due to the reduction in asphalt stiffness. Based on the test results, the most suitable waste cooking oil content was found to be within the range of 1.5%–3.0%, as all Marshall parameters remained within the specified limits. The 3.5% variation is not recommended because its flow value of 4.20 mm exceeded the maximum allowable specification. Furthermore, the utilization of waste cooking oil has the potential to serve as a cost-effective and environmentally friendly alternative material in road pavement construction.

Faktor yang Memengaruhi Pemilihan Moda Transportasi pada Pengguna Bus Trans Jatim Koridor Mojokerto-Jombang
type: item
description: Public transportation plays an important role in supporting community mobility and reducing dependence on private vehicles, particularly along the Mojokerto–Jombang corridor, which has relatively high travel intensity. However, the utilization of Trans Jatim Bus services along this corridor remains relatively low compared to private vehicles and other transportation modes. This study aims to analyze the factors influencing user preferences in transportation mode choice and to identify the most dominant attributes affecting the decision to use Trans Jatim Bus services. This research employed a quantitative method with a descriptive approach by distributing questionnaires to 97 respondents along the Mojokerto–Jombang corridor. The data were analyzed using binary logistic regression with the assistance of IBM SPSS Statistics 26. The results show that the regression model achieved a classification accuracy of 85.0% and a Nagelkerke R² value of 0.602, indicating that 60.2% of the variation in mode choice decisions can be explained by the variables included in the model. The Omnibus Test result showed a significance value of 0.000 (<0.05), indicating that the model is statistically significant. The variables that significantly influence the preference for using Trans Jatim Bus are income, travel experience, transportation mode used, factors influencing travel decisions, and preferred fare levels. Among the significant variables, preferred fare level had the smallest significance value, namely 0.009. Therefore, improving service quality, particularly in terms of fare affordability, comfort, and accessibility, is essential to increase public interest in using Trans Jatim Bus as a public transportation mode.

Optimalisasi Waktu dan Biaya Proyek Gelora Ahmad Yani Mojokerto Menggunakan Metode Time Cost Trade Off
type: item
description: The Gelora Ahmad Yani Infrastructure Project in Mojokerto experienced delays from week 5 to week 7, which could extend the project duration and increase construction costs. These delays required a measurable time and cost control evaluation to ensure more efficient project completion. This study aimed to determine the most optimal acceleration alternative for the project using the Time Cost Trade Off (TCTO) method. The research data consisted of the Budget Plan, project schedule, progress reports, working-hour data, and heavy equipment data. The analysis was conducted on critical path activities by comparing acceleration scenarios involving 1, 2, 3, and 4 hours of overtime work and the addition of a mini roller. The results show that the normal project condition had a duration of 90 days with a total cost of IDR 870,542,000.00. The most optimal alternative was the addition of heavy equipment, which produced a final duration of 25 days, representing an acceleration of 65 days or 72.22%. The total project cost decreased to IDR 843,848,152.79, with a saving of IDR 26,693,847.21 or 3.07% compared with the normal cost. Therefore, adding a mini roller is recommended as a more effective acceleration strategy, particularly for critical paving activities.

Behavioral Modeling dalam Pemilihan Moda Transportasi Melalui Analisis Preferensi Pengguna terhadap Bus Trans Jatim Rute Lamongan–Mojokerto
type: item
description: Effective public transportation is essential for reducing society's dependence on private vehicles and promoting sustainable mobility. The implementation of the Trans Jatim Bus service on the Lamongan–Mojokerto route is expected to provide a more efficient transportation alternative; however, the level of modal shift among the community still requires further investigation. This study aims to analyze the factors influencing people's decisions to shift to the Trans Jatim Bus and to determine the probability of modal shift occurrence. This research employed a quantitative approach through a questionnaire survey involving 100 respondents selected using purposive sampling. The collected data were analyzed using binary logistic regression to identify variables that significantly affect the decision to shift transportation modes. The results indicate that gender and travel frequency significantly influence modal shift decisions, with significance values of 0.031 and 0.047, respectively. The highest probability of modal shift was found among male respondents at 82.4%, while respondents who traveled daily showed a modal shift probability of 55.6%. These findings suggest that user characteristics and travel intensity play important roles in encouraging the use of public transportation. Therefore, improving service quality, particularly in terms of travel frequency, should become a priority for operators and government authorities to increase public interest in using the Trans Jatim Bus service.

Analisis dan Pemeringkatan Faktor Kritis yang Mempengaruhi Mutu Pengelasan Struktur Baja Menggunakan Relative Importance Index (RII)
type: item
description: Welding quality plays a crucial role in determining the strength, safety, and long-term performance of structural steel construction. Welding defects may lead to rework, project delays, additional costs, and reduced structural reliability. Therefore, identifying and prioritizing the factors influencing welding quality is essential for improving construction performance and quality management practices. This study aims to identify and rank the critical factors affecting structural steel welding quality using the Relative Importance Index (RII) method. A quantitative survey approach was employed in this study. Data were collected from 100 construction professionals, including engineers, welders, quality control personnel, welding inspectors, supervisors, and project practitioners involved in structural steel works. The questionnaire was developed based on the AWS D1.1 standard and relevant literature and distributed through Google Forms via WhatsApp between March and April 2026. The research instrument consisted of 24 causal-factor indicators grouped into six dimensions, namely technical aspects, documentation, human resources, supervision, management, and work environment, as well as five welding-quality outcome indicators. Reliability testing showed that the overall instrument achieved a Cronbach’s Alpha value of 0.984, indicating excellent internal consistency. The results of the Relative Importance Index analysis revealed that the five most influential factors affecting welding quality were quality control supervision before, during, and after welding activities, cleanliness of the welding area from contaminants, compliance with AWS D1.1 standards, availability of competent welding inspectors, and the use of calibrated and well-maintained welding equipment. These findings indicate that welding quality is influenced not only by technical factors but also by effective supervision systems, personnel competency, and adherence to quality management procedures. The stud…

Evaluasi Daya Dukung Tanah Dasar Berdasarkan Nilai CBR Hasil Pengujian DCP pada Ruas Jalan Tikung–Kembangbahu Kabupaten Lamongan
type: item
description: The Tikung–Kembangbahu road section in Lamongan Regency shows several indications of pavement distress; therefore, the bearing capacity of the subgrade needs to be evaluated as one of the bases for road treatment. This study aims to evaluate the subgrade bearing capacity based on the California Bearing Ratio (CBR) obtained from Dynamic Cone Penetrometer (DCP) testing. The test was conducted at five points with an interval of 200 m along a 1,000 m road section. The DCP penetration data were converted into CBR values, and the CBR values of the subgrade layer were used to determine the design CBR. The results show that the subgrade CBR values at the five test points were 12.8%, 3.23%, 3.3%, 8.42%, and 10.9%. The lowest CBR value of 3.23% was selected as the design CBR because the number of test points in one segment was less than ten. This value is lower than the minimum CBR requirement of 6%, indicating that subgrade improvement is required before pavement design. Based on the Bina Marga Pavement Design Manual, the recommended thickness of the subgrade improvement layer is 200 mm.

Pengaruh Serat Polypropylene Terhadap Pola Retak dan Kuat Tekan Beton Berbasis Agregat Ringan Batu Apung
type: item
description: Lightweight concrete based on pumice aggregate has relatively high compressive strength; however, it is brittle and prone to cracking under loading, which can reduce the durability and service life of structures. The addition of polypropylene fibers is expected to improve crack resistance and enhance the mechanical properties of concrete. This study aims to evaluate the effect of polypropylene fiber addition on the compressive strength, splitting tensile strength, and crack pattern of structural lightweight concrete. An experimental method was employed using polypropylene fiber contents of 0%, 0.02%, 0.04%, and 0.06% by concrete volume. Tests were conducted on compressive strength, splitting tensile strength, and crack patterns at the age of 28 days. The results indicate that the addition of 0.02% polypropylene fibers produced the highest compressive strength of 22.20 MPa and the highest splitting tensile strength of 2.56 MPa compared to concrete without fibers. The addition of polypropylene fibers was also able to reduce crack width and control crack propagation, resulting in a more ductile failure behavior. However, higher fiber contents reduced the workability of the concrete mixture and decreased compressive strength due to less uniform fiber distribution. Based on these findings, the use of 0.02% polypropylene fiber is recommended as the optimum content to improve the mechanical performance and crack resistance of structural lightweight concrete without significantly reducing workability. Further studies are recommended to investigate fiber combinations or variations in concrete strength in order to evaluate long-term durability and crack behavior.

Pengaruh Limbah Potongan Baja Ringan terhadap Kuat Lentur Beton
type: item
description: The utilization of concrete in the construction industry is highly massive due to its superior compressive strength; however, this activity also triggers a surge in waste, such as lightweight steel scraps. To address these environmental issues, this study examines the optimization of lightweight steel waste as a concrete additive because of its high tensile strength characteristics. Testing was conducted through an experimental method at the Civil Engineering Laboratory of Universitas Islam Lamongan to analyze the comparison of flexural strength between normal concrete and varied concrete mixtures. The percentages of the added material tested included 0%, 2%, 4%, and 6% of the total gravel weight. Based on the experimental results, normal concrete produced a flexural strength of 3.31 MPa, while the 2%, 4%, and 6% mixed variations sequentially surged to 5.16 MPa, 5.30 MPa, and 6.93 MPa. These data prove that an increase in the content of lightweight steel waste is directly proportional to the enhancement of the concrete's flexural strength quality. Therefore, this residual material is highly recommended as an alternative substitution ingredient to improve structural quality while reducing the negative impact of construction project waste.

Pengaruh Abu Sekam Padi Sebagai Substitusi Abu Terbang (Fly ash) Terhadap Nilai Kuat Tekan Beton Geopolimer
type: item
description: Conventional concrete uses cement as the primary binding material, which produces significant carbon dioxide (CO₂) emissions and contributes to environmental problems. One environmentally friendly alternative is geopolymer concrete that utilizes pozzolanic materials such as fly ash and rice husk ash as binding materials. This study aims to determine the effect of rice husk ash as a substitution for fly ash on the compressive strength of geopolymer concrete. The research was conducted experimentally using cylindrical specimens with a diameter of 15 cm and a height of 30 cm, with rice husk ash variations of 0%, 5%, 10%, and 15% by weight of fly ash. Compressive strength testing was carried out at the ages of 7 and 28 days using a Compression Testing Machine (CTM). The results showed that increasing the percentage of rice husk ash tended to reduce the compressive strength of geopolymer concrete under both curing methods. Under ambient curing conditions, the 28-day compressive strength decreased from 15.85 MPa for GP0 to 5.66 MPa for GP15. Under oven curing conditions, the 28-day compressive strength decreased from 37.795 MPa for GP0 to 7.925 MPa for GP15. In addition, the observed crack patterns were cone and cone and split. These findings indicate that the use of rice husk ash as a partial substitution for fly ash affects the mechanical properties of geopolymer concrete, particularly its compressive strength.

Pengaruh Substitusi Pasir Limbah Tailing Emas Sebagai Agregat Halus terhadap Sifat Mekanik Beton Normal
type: item
description: The increasing demand for natural sand as fine aggregate in concrete mixtures encourages the utilization of more environmentally friendly alternative materials, one of which is gold mining tailings waste sand. This study aims to analyze the effect of substituting gold mining tailings waste sand as a partial replacement for fine aggregate on the fresh concrete characteristics and mechanical properties of normal concrete. The research was conducted experimentally using four mixture variations, namely normal concrete, BTL 10%, BTL 20%, and BTL 30%. The concrete mix design referred to SNI 03-2834-2000, while the specimens were cylindrical with dimensions of 150 mm × 300 mm and tested at the age of 28 days. The parameters tested included slump value, fine aggregate specific gravity, compressive strength, and splitting tensile strength. The results showed that normal concrete had the highest compressive strength of 20.27 MPa, while the 10% tailings variation decreased by 9.22% to 18.40 MPa, the 20% variation decreased by 4.75% to 19.31 MPa, and the 30% variation decreased by 0.09% to 20.25 MPa. In the splitting tensile strength test, normal concrete had a value of 1.72 MPa, while the 10%, 20%, and 30% variations had values of 1.75 MPa, 1.73 MPa, and 1.72 MPa, respectively. These results indicate that the use of gold mining tailings waste sand up to 30% is still capable of producing compressive strength nearly equivalent to normal concrete, while the 10% substitution provided the highest increase in splitting tensile strength of 1.37% compared to normal concrete. This study demonstrates that gold mining tailings waste sand has the potential to be utilized as an environmentally friendly alternative fine aggregate material without significantly reducing the mechanical properties of concrete

Analisis Faktor Penyebab Kecelakaan Lalu Lintas pada Jalan Raya Legundi – Bypass Krian STA 0+000 – STA 5+100
type: item
description: Traffic accidents remain one of the major transportation problems that continue to increase along with population growth and the rising mobility of the community. This condition leads to a higher risk of traffic accidents, resulting in both material and non-material losses while endangering road users' safety. One of the road sections with a relatively high accident rate is the Legundi–Bypass Krian Road in Sidoarjo Regency, where 23 traffic accident cases were recorded by the Traffic Accident Unit of the Sidoarjo Regional Police in 2024. This study aims to analyze the factors causing traffic accidents, identify accident-prone locations, and evaluate the condition of road safety facilities along the Legundi–Bypass Krian Road. The methods employed include the Accident Equivalent Number (AEN) and the Upper Control Limit (UCL) to identify accident-prone areas (black spots), Importance Performance Analysis (IPA) to analyze accident-causing factors based on road users' perceptions, and a scoring method to assess the feasibility of road safety facilities. The results indicate that human factors are the dominant cause of traffic accidents, several road segments are identified as accident-prone locations based on AEN values exceeding the UCL, and a number of road safety facilities are still in suboptimal condition. Therefore, improving road safety facilities and implementing appropriate treatments at accident-prone locations are recommended to enhance traffic safety.

Perbandingan Kuat Tekan pada Beton SCC Menggunakan Bahan Zat Aditif yang Bersifat Accelerator dan Retarder dengan Metode Destructive Test
type: item
description: The ever-evolving construction industry demands innovation in high-quality, economical, and efficient concrete materials. Self-Compacting Concrete (SCC) is one solution due to its self-compacting ability. However, extreme conditions often affect the setting and hardening time of concrete, requiring the use of additives in the form of accelerators to accelerate or retarders to slow down the setting time. This study aims to analyze and compare the compressive strength values of SCC concrete using accelerator and retarder additives through a destructive test method. This study was conducted at the Civil Engineering Laboratory of the University of Muhammadiyah Mataram. The test specimens used were concrete cylinders measuring 15 cm x 30 cm with a design compressive strength of f’c = 20 MPa and an additive dosage of 0.5%. Fresh concrete characteristics testing included slump flow, J-ring, and sieved stability index. The compressive strength testing of hardened concrete was carried out using a Compression Testing Machine (CTM) at the ages of 7, 14, 21, and 28 days. The test results showed that the material and fresh concrete had met all the eligibility criteria for SCC concrete, with a slump flow distribution value of 65 cm, J-ring 67 cm, and a sieve stability index of 17.52%. The use of accelerator additives proved to be the most effective in increasing early strength and producing the highest compressive strength of 24,84 MPa on the 28th day. The use of retarder produced a compressive strength below normal concrete at the age of 7 days (14.60 MPa compared to 15.56 MPa), but showed a better increase in strength at the age of 28 days. Overall, the choice of additive type must be adjusted to the needs, accelerator is effective in accelerating hardening, while retarder is more suitable for improving long-term workability.

Analisis Kesediaan dan Kemampuan Membayar terhadap Persepsi Kewajaran Tarif LRT Jabodebek pada Jam Sibuk dan Non-Sibuk (Studi Kasus: Stasiun Harjamukti)
type: item
description: High mobility in the Greater Jakarta (Jabodetabek) area, which is dominated by private vehicle use, has led to congestion and transportation inefficiency. The LRT Jabodebek was introduced as a mass transit alternative; however, its passenger occupancy rate remains suboptimal. This study aims to analyze the influence of Willingness to Pay (WTP) and Ability to Pay (ATP) on fare fairness perception during peak and off-peak hours, as well as to identify the dominant variable. A quantitative method with descriptive and verificative approaches was employed through a Likert-scale questionnaire distributed to users at Harjamukti Station. The data were analyzed using multiple linear regression. The results indicate that both WTP and ATP have a positive and significant effect on fare fairness perception. During peak hours, WTP is the dominant variable, whereas ATP is more dominant during off-peak hours. A fare of IDR 20,000 during peak hours tends to be rejected, while a fare of IDR 10,000 during off-peak hours is more acceptable. These findings suggest the need for a time-based fare policy to improve affordability and user acceptance.

Sifat Mekanik Beton dengan Substitusi Limbah Kaca dan Penambahan SikaCim Concrete Additive
type: item
description: The demand for high-strength concrete in Indonesia continues to grow, yet the exploitation of natural sand as fine aggregate poses a risk of environmental damage, creating a need for alternative materials. This study aims to analyze the effect of glass waste substitution on the mechanical properties of high-strength concrete (design f'c of 40 MPa) with SikaCim Concrete Additive. The method used was a laboratory experiment on cylindrical specimens (10×20 cm) with glass waste substitution for fine aggregate at 0%, 10%, 20%, and 30%, including slump testing, compressive strength testing (Compression Testing Machine), and splitting tensile strength testing at 7, 14, 21, and 28 days. The results showed that compressive strength decreased consistently as the substitution level increased, from 37.66 MPa (normal concrete) to 35.37 MPa (10%), 34.01 MPa (20%), and 33.67 MPa (30%), a decline of up to 10.59%. In contrast, splitting tensile strength followed a non-monotonic pattern: it dropped sharply at 10% substitution (3.56 MPa; a 20.54% decrease), then rose again at 20% (3.74 MPa) and 30% (4.30 MPa), approaching the value of normal concrete (4.48 MPa), with the highest ft/√f'c ratio occurring at 30% substitution (0.741), exceeding that of normal concrete (0.730). It is concluded that within the 0–30% substitution range, glass waste did not produce an optimum point that increased compressive strength above that of normal concrete, but at 30% it provided a relatively better balance between compressive and splitting tensile strength, indicating that the feasibility of using glass waste cannot be assessed from compressive strength alone.

Analisis Percepatan Waktu Menggunakan Metode Crashing dengan Penambahan Jam Kerja Tiga Jam dan Sistem Shift
type: item
description: During the construction process of a project, many unexpected events can occur, one of which is project delays. These delays may result from various factors such as unfavorable weather conditions, design changes, planning errors, and several others. Therefore, it is necessary to consider alternative strategies to support project acceleration. These alternatives may include extending working hours, using more productive equipment, increasing the number of workers, utilizing materials that are quicker to install, and implementing faster construction methods. This study analyzes the acceleration of project completion time in the construction project of SMPN 3 using the crashing method, with two alternatives: extending working hours by three hours and implementing a shift system. The objective of this research is to determine the total project duration after applying crashing with the two alternatives and to identify which critical path activities were accelerated in the SMPN 3 construction project. Based on the analysis, the total project duration after crashing using the three-hour extended workday alternative is 175 days, representing a time savings of approximately 20% compared to the normal duration of 218 days. Meanwhile, the total project duration after crashing using the shift system alternative is 109 days, resulting in a time savings of approximately 50% from the original duration of 218 days.

Pengaruh Limbah Kaca Sebagai Substitusi Agregat Halus terhadap Sifat Mekanik Beton Normal
type: item
description: The increasing development of the construction industry has led to a growing demand for natural aggregates, while the accumulation of non-biodegradable waste glass continues to increase, posing potential environmental problems. One effort to reduce these impacts is to utilize waste glass as a partial substitute for fine aggregate in normal concrete mixtures. This study aimed to analyze the effect of waste glass as a partial replacement for fine aggregate on the mechanical properties of normal concrete, including compressive strength and splitting tensile strength. An experimental method was employed at the Civil Engineering Laboratory of Universitas Muhammadiyah Mataram using cylindrical concrete specimens with dimensions of 100 mm × 200 mm. The waste glass substitution levels were 0%, 10%, 20%, and 30% by weight of fine aggregate. Compressive strength and splitting tensile strength tests were conducted at the age of 28 days using a Compression Testing Machine (CTM). The results showed that the average compressive strength of normal concrete was 16.22 MPa, while the concrete containing 10%, 20%, and 30% waste glass achieved average compressive strengths of 26.37 MPa, 21.74 MPa, and 20.34 MPa, respectively. The highest compressive strength was obtained at the 10% substitution level. Meanwhile, the average splitting tensile strength of normal concrete was 2.01 MPa, whereas the concrete containing 10%, 20%, and 30% waste glass produced average splitting tensile strengths of 2.99 MPa, 2.48 MPa, and 2.20 MPa, respectively. The highest splitting tensile strength was also achieved at the 10% substitution level. Based on these findings, the use of 10% waste glass as a partial replacement for fine aggregate provides the most optimal improvement in the mechanical properties of normal concrete and has the potential to serve as an environmentally friendly alternative material for sustainable construction.

Evaluasi Standar Pelayanan Minimum dan Tingkat Kepuasan Penumpang terhadap Fasilitas Pelayanan di Terminal Kepuhsari Kabupaten Jombang
type: item
description: Kepuhsari Terminal in Jombang Regency plays a strategic role as a Type B passenger terminal serving Rural Transportation, Inter-City Within Province (AKDP), and Inter-City Between Provinces (AKAP) services. However, the terminal's facilities and operations still exhibit several deficiencies, including inadequate waiting areas, damaged and poorly maintained sanitation facilities, limited service information, and insufficient maintenance. These conditions reduce the comfort and safety of terminal users. This study aimed to evaluate the conformity of the terminal's physical facilities with the Minimum Service Standards (MSS) stipulated in the Minister of Transportation Regulation No. PM 40 of 2015 and to analyze passenger satisfaction with the terminal services. A quantitative descriptive approach was employed. Data were collected through field observations to assess the physical condition of the terminal based on the MSS and through questionnaires administered to 100 users of Kepuhsari Terminal. The data were analyzed using Importance–Performance Analysis (IPA) to identify service attributes requiring priority improvement and the Customer Satisfaction Index (CSI) to measure overall passenger satisfaction. The IPA results showed that the average facility performance score was 2.65, while the average importance score was 3.30. The CSI value was 53.02%, which falls within the 40%–60% range and indicates a moderately satisfied level of passenger satisfaction. These findings suggest that the quality of services at Kepuhsari Terminal requires further improvement, particularly for service attributes with high importance but relatively low performance.

Pengaruh Abu Tempurung Kelapa Sebagai Substitusi Sebagian Semen terhadap Kuat Tekan Beton K-250
type: item
description: Concrete is one of the most widely used construction materials. Therefore, efforts are needed to reduce cement consumption by utilizing waste materials, one of which is coconut shell ash. This study aimed to determine the effect of partially replacing cement with coconut shell ash on the compressive strength of K-250 concrete. An experimental method was employed using coconut shell ash replacement levels of 0%, 2%, 4%, and 6% by the weight of cement, with compressive strength testing conducted at 28 days. The average compressive strength of normal concrete was 20.81 MPa, while concrete with 2%, 4%, and 6% coconut shell ash substitution achieved average compressive strengths of 19.25 MPa, 18.35 MPa, and 17.85 MPa, respectively. The results indicate that increasing the percentage of coconut shell ash substitution tends to reduce the compressive strength of concrete. Therefore, the use of coconut shell ash as a partial replacement for cement at the substitution levels investigated was not able to improve the compressive strength of K-250 concrete.

Perencanaan Penerapan Simpang Ber-APILL dengan Pendekatan PKJI 2023 Dan VISSIM (Studi Kasus: Simpang 4 Jalan Raya Mataram-Tanjung)
type: item
description: The Lendang Bajur Four-Leg Intersection is one of the main intersections connecting Mataram City with the Senggigi tourism area and North Lombok, resulting in relatively high traffic volumes, particularly during peak hours. These conditions may increase traffic conflict and reduce intersection performance. This study aims to analyze the existing intersection performance and evaluate the implementation of a traffic signal system using the Indonesian Highway Capacity Manual (PKJI 2023) and PTV VISSIM simulation software. The research began with traffic volume surveys and geometric measurements, followed by analyses of capacity, degree of saturation, delay, and signal cycle time based on PKJI 2023. The proposed signal timing was subsequently modeled using PTV VISSIM to evaluate the operational performance of the intersections. The analysis produced an optimum signal cycle time of 49 seconds, with an average approach delay ranging from 21.26 to 34.21 seconds per vehicle. The VISSIM simulation indicated that several traffic movements still experienced relatively high vehicle delays due to traffic movement characteristics and operational conditions at the intersections. The differences between PKJI 2023 and PTV VISSIM results are attributed to their different analytical approaches, indicating that both methods complement each other in evaluating intersection performance. The findings are expected to provide a reference for planning signalized intersections with similar traffic characteristics.

Analisis Tingkat Kepuasan Penumpang Kereta Cepat terhadap Fasilitas dan Pelayanan Stasiun Halim Menggunakan SERVQUAL Berbasis Website
type: item
description: The rapid development of high-speed railways requires service providers to continuously improve station facilities and service quality to meet passenger expectations. Although the Service Quality (SERVQUAL) method has been widely applied to evaluate service quality, studies integrating data collection, processing, and real-time visualisation into a single web-based platform remain limited, particularly in Indonesia's high-speed railway services. This study aims to analyse passenger satisfaction with the facilities and services at Halim Station using a web-based SERVQUAL approach while developing a digital platform to support continuous service evaluation. A quantitative approach was employed involving 131 respondents selected through purposive sampling. Data were collected using a web-based questionnaire measuring passengers' perceptions and expectations and were analysed through validity and reliability tests, followed by SERVQUAL gap analysis across five service quality dimensions. The results indicate that all questionnaire items are valid and reliable, and the overall service quality of Halim Station is classified as very good, with an average perception score of 4.5974. Positive gaps were identified in the responsiveness, assurance, and empathy dimensions, whereas the tangibles and reliability dimensions exhibited slight negative gaps, indicating areas requiring improvement. This study develops a web-based system that integrates questionnaire data collection, SERVQUAL gap calculation, data recapitulation, and survey result visualisation. The system helps improve the efficiency of service monitoring and assists in making decisions based on station management data. By combining SERVQUAL with a digital web-based platform, this approach offers a more efficient method for supporting continuous service quality evaluation in railway station services.

Analisis Pondasi Tiang Pancang Pipa Baja Jembatan Parit 3 Kec. Kuala Jambi
type: item
description: Steel pipe pile foundations function to transfer superstructure loads to the supporting soil layer while providing resistance to axial and lateral forces. These foundations are widely used not only for buildings but also for various civil engineering structures, including bridges. The Parit 3 Bridge in Kuala Jambi District was constructed to reconnect two disconnected road sections, thereby improving local community accessibility. This study aimed to analyze the bridge structural loading and determine the bearing capacity of the steel pipe pile foundation using the Schmertmann and Nottingham method. Bridge loading calculations were performed in accordance with SNI 1725:2016, while the foundation bearing capacity was evaluated using the Schmertmann and Nottingham method. The results indicated that the maximum factored ultimate load under the Strength 1 load combination was Pu = 3,695.00 kN, equivalent to 376.79 tons. The allowable bearing capacity of a single pile was Qa = 739.538 kN, equivalent to 75.411 tons, whereas the bearing capacity of the pile group was Qg = 7,395.380 kN, equivalent to 751.841 tons. The calculated pile group bearing capacity exceeded the maximum applied load, indicating that the foundation satisfied the required bearing capacity criteria. Furthermore, both the single-pile settlement and the pile-group settlement were smaller than the allowable settlement, demonstrating that the settlement requirements were also satisfied.

Integrasi Data Pemeriksaan Geometri dan Estimasi Waktu–Biaya pada Perencanaan Pemeliharaan Jembatan Jalan Tol Layang MBZ
type: item
description: Condition-based bridge maintenance requires the integration of information on the actual structural condition, implementation time, and costs to ensure effective and efficient infrastructure asset management. This study aims to analyze the integration of geometric inspection data with time and cost estimates in the maintenance planning of the Sheikh Mohammed Bin Zayed (MBZ) Elevated Toll Road Bridge. The study employed a qualitative approach with a case study design. Secondary data were obtained from the contractor, including geometric measurement results collected using a Robotic Total Station (RTS), dual-frequency geodetic GPS, and a digital level, as well as the Bill of Quantities (BoQ), project schedule, and other technical documents. Data were collected through document analysis and analyzed using the interactive model of Miles, Huberman, and Saldaña, consisting of data condensation, data display, and conclusion drawing and verification. The results show that geometric inspection data can be integrated with project schedule and budget information within a unified maintenance-planning information framework. The geometric inspection, data processing, and preparation of the maintenance plan were completed within 90 calendar days at a total cost of IDR 965,061,750. The integration of geometric, time, and cost data provides more structured planning information to support the implementation of condition-based maintenance. However, the integration remains at the planning-information level and does not yet establish a quantitative relationship between geometric changes and the type, volume, duration, and cost of physical repair works. This study strengthens the application of condition-based maintenance and integrated asset management and provides practical implications for toll road operators in improving planning accuracy and bridge maintenance efficiency.

Analisis Daya Dukung Fondasi Foot Plate Menggunakan Metode Meyerhof dan Terzaghi Studi Kasus RSJ Mutiara Sukma
type: item
description: A foundation is a structural element that transfers building loads to the soil layer, thereby ensuring the stability of the construction. The foot plate foundation is a type of shallow foundation commonly used for low- to medium-rise buildings. This study aims to analyze the bearing capacity of foot plate foundations using the Terzaghi and Meyerhof methods and to compare the calculation results from both methods within the context of the construction of the Drug Rehabilitation Building at Mutiara Sukma Psychiatric Hospital, Mataram City. The study employs a quantitative method with a comparative analysis approach. The data utilized consists of secondary data from Cone Penetration Tests (CPT/sondir) and foundation design drawings. The Meyerhof and Terzaghi methods yielded different bearing capacity values at each testing point; these differences are attributable to the specific equations, soil parameters, and correction factors employed. This study could not determine the most representative method, as no validation was performed using load tests or actual settlement data. Regarding the allowable bearing capacity of the shallow foundations, the values were obtained using the Terzaghi method: 20095,12 kN at point 1 (compared to 11641,73 kN via Meyerhof). At point S2, the values were 3,699.94 kN (Terzaghi) and 2,206.28 kN (Meyerhof); at point S3, they were 9,208.03 kN (Terzaghi) and 11,949.39 kN (Meyerhof); and finally, at point S4, the values were 8,395.88 kN (Terzaghi) and 5,051.14 kN (Meyerhof).

Perencanaan Ulang Struktur Gedung Rumah Susun Negara Kementerian Keuangan 25 Lantai Tahan Gempa Menggunakan Sistem Ganda (Dual System) di Jakarta Barat
type: item
description: Urban population growth has driven a high demand for vertical housing that is efficient and highly resilient to lateral loads. The Ministry of Finance's State Apartment Building in West Jakarta, initially constructed with 12 stories, is being redesigned into a 25-story structure to optimize land utilization. This study aims to design the main structural elements of the upgraded building using a Dual System while performing comprehensive structural performance evaluations in accordance with seismic resistance standards. The analysis employed the dynamic response spectrum method via ETABS v22.7, incorporating West Jakarta's specific seismic parameters for soft soil conditions (Site Class SE). Furthermore, the structural model was integrated into Building Information Modeling (BIM) using Autodesk Revit 2025 to generate reinforcement detailing and material quantity estimates. Analytical results demonstrate that the redesigned structural elements successfully satisfy all performance criteria. Story drift remains within safe boundaries, the structure maintains stability against P-Delta effects, and the Strong Column-Weak Beam principle is well fulfilled. The implementation of the Dual System yielded a Special Moment Resisting Frame (SMRF) participation of 79.8% in the X-direction and 53.8% in the Y-direction. Additionally, it restricted the maximum story drift to 50.204 mm well below the 72 mm allowable limit—proving its effectiveness in providing the requisite lateral stiffness and ductility. Overall, the structural design strictly conforms to SNI 1726:2019, SNI 1727:2020, SNI 2847:2019, and SNI 2052:2024 provisions. The BIM integration also successfully produced technical working drawings and highly accurate Quantity Take-Off (QTO) calculations.

Evaluasi Kapasitas Saluran Eksisting terhadap Debit Limpasan sebagai Kajian Perancangan Saluran Drainase di Perumahan Sukawinatan Permai Indah
type: item
description: The rapid expansion of residential areas in Palembang City through swamp land reclamation without the application of eco-drainage principles has increased the occurrence of local flooding by reducing natural infiltration capacity. This condition has significantly affected the Sukawinatan Permai Indah Residential Area, where inundation and drainage overflow frequently occur during heavy rainfall. This study evaluates the hydraulic performance of the existing drainage network in conveying the design storm runoff within the residential area. A quantitative approach was adopted using annual maximum daily rainfall data for the period 2013–2022 obtained from the Meteorological, Climatological, and Geophysical Agency (BMKG). Design rainfall was estimated using the Log Pearson Type III distribution, while peak runoff discharge was calculated using the Rational Method. The analysis produced a 10-year return period rainfall of 173.76 mm. Hydraulic evaluation revealed that the existing drainage system is incapable of conveying the design runoff because of inadequate channel dimensions, structural deterioration, and significant sediment deposition. The average runoff discharge along the drainage reaches was 0.0037 m³/s, the maximum discharge reached 0.0327 m³/s, and the cumulative discharge at the outlet was 2.5536 m³/s. These findings indicate that the existing drainage network requires substantial improvement. Accordingly, the drainage system should be redesigned and reconstructed based on hydraulic design standards while incorporating eco-drainage principles to enhance runoff management. In addition, regular inspection and maintenance are essential to ensure the long-term effectiveness and sustainability of the drainage system in mitigating urban flooding.

title: Analisis Kondisi Kerusakan dan Prioritas Penanganan Jalan Menggunakan PKRMS dengan Pendekatan Surface Distress Index dan Road Condition Index (Studi Kasus: Ruas Jalan Malimbu-Pengempus Sari, Kabupaten Lombok Utara)
description: Roads are a vital land transportation infrastructure that supports community mobility and regional economic development. However, as the service life of a pavement increases, its condition gradually deteriorates due to repeated traffic loading and environmental factors. If not properly managed, pavement deterioration may reduce the level of road service, increase the risk of traffic accidents, and raise vehicle operating costs. Therefore, periodic pavement condition evaluation is essential to identify the extent of deterioration and to determine appropriate maintenance priorities. This study aims to assess pavement conditions using the Provincial/Kabupaten Road Management System (PKRMS) through the Surface Distress Index (SDI) method, evaluate the functional condition of the road using the Road Condition Index (RCI) method, and determine maintenance priorities for the Malimbu–Pengempus Sari Road in North Lombok Regency. A visual pavement survey was conducted on 51 road segments, and the collected data were processed using the PKRMS application to obtain SDI and RCI values as well as maintenance recommendations. The SDI analysis indicated that 17 segments (33.33%) required routine maintenance, 21 segments (41.18%) required periodic maintenance, and 13 segments (25.49%) required reconstruction. The highest SDI value of 265 was identified at STA 1+600–1+700, STA 2+300–2+400, STA 2+500–3+400, STA 4+000–4+200, and STA 4+400–4+600, where the predominant pavement distresses consisted of potholes and surface deformation. Meanwhile, the RCI values ranged from 4.00 to 6.00, indicating that the functional condition of the road varied from fair to good. The integration of SDI and RCI through the PKRMS application produced maintenance priorities dominated by periodic maintenance, followed by routine maintenance and reconstruction, according to the condition of each road segment. The findings demonstrate that integrating SDI and RCI within the PKRMS framework provides a more obje…

Analisis Kapasitas Sungai terhadap Pengendalian Debit Banjir (Studi Kasus Sungai Kendal)
type: item
description: Kendal Regency is located on the north coast of Java and is administratively divided into 20 districts, 265 villages, and 20 urban villages. The topography of Kendal Regency varies significantly, ranging from lowlands in the north to hilly terrain in the south. High annual sedimentation in the river channel—caused by soil erosion in the upstream areas of the Kendal watershed—can reduce the river's capacity to accommodate flood discharge. This study aims to determine the design flood discharge for the Kendal River, analyze the river's cross-sectional capacity to handle this discharge using HEC-RAS modeling, evaluate the existing capacity, and identify necessary improvements such as river normalization or levee raising. The methodology involved hydrological analysis to determine flood discharge for specific return periods and hydraulic analysis to evaluate both existing and proposed river cross-sections. The calculated design flood discharges for the Kendal River—using the Rational Method for return periods of 2, 5, 10, and 20 years—were 149.766 m³/s, 198.220 m³/s, 229.055 m³/s, and 255.484 m³/s, respectively. HEC-RAS hydraulic modeling results indicate that the existing Kendal River cross-section is incapable of accommodating the design flood discharge for these return periods; specifically, the analysis shows that the current capacity is insufficient to manage the Q20 flood event. Consequently, river normalization is recommended; a proposed normalization alternative featuring a trapezoidal cross-section—with a base width of approximately 10 meters, a top width of approximately 20 meters, and a depth of approximately 6 meters—demonstrated increased capacity in HEC-RAS simulations.

Daya Dukung Fondasi Dangkal dan Dalam Gudang Air Minum dalam Kemasan (AMDK) Kota Malang
type: item
description: Foundation design plays a crucial role in ensuring structural stability and safety, particularly for industrial buildings constructed on cohesive soils. Soil characteristics significantly influence the selection of foundation types and their bearing capacities; therefore, an evaluation of both shallow and deep foundations under the same soil conditions is required. This study aims to determine the bearing capacity of shallow foundations using Standard Penetration Test (SPT) data, evaluate the bearing capacity of deep foundations based on Cone Penetration Test (CPT) data, and analyze the effect of foundation dimension variations for the planned Bottled Drinking Water (AMDK) warehouse in Malang City. The study employed a quantitative descriptive approach using secondary data obtained from geotechnical investigations and laboratory testing. The bearing capacity of shallow foundations was analyzed using the Terzaghi method, while the bearing capacity of deep foundations was calculated using an empirical approach based on CPT data. The results indicate that the bearing capacity of shallow foundations at a depth of 5 m ranges from 15.1 to 32.1 t/m² for strip foundations, 19.1 to 37.0 t/m² for circular foundations, and 19.1 to 37.4 t/m² for square foundations. Meanwhile, the bearing capacity of deep foundations at a depth of 10 m ranges from 399.07 to 1,617.29 tons, depending on the pile diameter used. The findings demonstrate that the Terzaghi method remains a relevant preliminary approach for evaluating foundation bearing capacity in relatively homogeneous cohesive soils. These results may serve as an initial reference for selecting alternative foundation systems; however, further verification is still required during the detailed planning and design stages.

Analisis Gradasi Butiran Limbah Rubber Deposit Runway (LRDR) sebagai Pengganti Agregat Halus pada Campuran Beton
type: item
description: Rubber deposit waste generated from aircraft tire abrasion on airport runways has potential as a substitute material for fine aggregate in concrete mixtures, in line with the need to reduce dependence on natural aggregates whose extraction can damage ecosystems. This study aims to analyze the grain characteristics of rubber deposit waste compared to sand as a conventional fine aggregate, as a preliminary feasibility study for its use in concrete mixtures. The research employed a quantitative method with an experimental approach through sieve analysis testing using a Sieve Shaker, with three repetitions for each material, followed by comparative analysis. The results show that, visually, rubber deposit waste appears darker than sand due to its material content, which mostly originates from the abrasion of aircraft rubber tires. The sieve analysis results indicate that rubber deposit waste generally has finer grains than sand, marked by a passing percentage on the 0.425 mm sieve of 66.91% compared to 26.72% for sand, and a much higher content of very fine particles (passing the 0.075 mm sieve), namely 11.01% compared to 0.49% for sand. This gradation difference indicates that rubber deposit waste has potential as a partial substitute for fine aggregate, although its high fine-particle content needs to be further considered in relation to water demand and the workability of the concrete mixture. This study provides a basis for further research on the effect of rubber deposit waste substitution on the physical and mechanical properties of concrete.

Analisis Pengaruh Jarak Excavator terhadap Stabilitas Dinding Penahan Tanah Menggunakan Pendekatan Beban Garis (Studi Kasus: Konstruksi Kanal di Batam)
type: item
description: The operation of heavy equipment during construction activities generates additional loads that may affect the stability of retaining walls, particularly when the equipment operates close to the structure. In the construction project of a luxury accommodation complex in Batam City, the canal structure at STA 0+220–0+230 experienced an overturning failure, which was presumed to be influenced by the operational load of a Hyundai R140LC-9S excavator. This study aims to analyze the effect of excavator operating distance on retaining wall stability using a line load approach. The research employed an analytical method through manual calculations of lateral earth pressure, overturning stability, sliding stability, and bearing capacity under the existing condition, followed by manual line load calculations obtained by simplifying the excavator load and evaluating the effect of different excavator operating distances on the safety factors. The results indicate that the safety factors for overturning, sliding, and bearing capacity under the existing condition were 2.337, 1.676, and 4.245, respectively. When the excavator operated at a distance of 2 m, the safety factors decreased to 1.831, 1.306, and 1.907, respectively. At an operating distance of 4 m, the safety factors increased to 2.128, 1.514, and 3.021, respectively, satisfying the minimum requirements specified in SNI 8460:2017. Therefore, the closer the excavator operates to the retaining wall, the greater the reduction in stability. Among the operating distances evaluated in this study, 4 m was the shortest distance that satisfied all safety-factor requirements specified in SNI 8460:2017.

Perubahan Tutupan Lahan pada DAS Bendung Kota Palembang dengan Metode NDVI
type: item
description: Rapid urban development to accommodate population growth has led to significant land use changes. The Bendung Watershed, located in Palembang City, is one of the areas with a high potential for flooding. Several factors contribute to flooding in Palembang, including inadequate drainage system performance, extensive swamp reclamation over the years, low-lying topography, and land use changes. Land cover change is one of the factors affecting flood discharge; therefore, this study aims to analyze land cover changes in the Bendung Watershed using the Normalized Difference Vegetation Index (NDVI) method based on Landsat remote sensing imagery from 2005 and 2024. The research methodology included watershed boundary delineation using DEM SRTM data, processing of Landsat imagery through geometric and radiometric corrections, band composite generation, NDVI transformation, land cover classification, and classification accuracy assessment. The results indicate that between 2005 and 2024, the built-up area increased by 21.15%, while open space and water bodies decreased by 40.98% and 36.89%, respectively.

Analisis Risiko Keselamatan dan Kesehatan Kerja pada Produksi Tiang Pancang Pracetak dengan Metode HIRARC
type: item
description: The precast concrete industry involves the use of reinforcement-processing machinery, prestressing systems, batching plants, overhead cranes, heavy equipment, and lifting and material-handling activities that may pose occupational accident risks. This study aims to identify hazards, assess risk levels, and formulate risk-control recommendations for the precast pile production process at PT X, Kutai Kartanegara. A qualitative descriptive approach was employed using the Hazard Identification, Risk Assessment, and Risk Control (HIRARC) method. Data were collected through field observations, documentation, and interviews with four respondents selected through purposive sampling, consisting of one section head, one operator, and two workers. Risk levels were determined by combining the likelihood of occurrence and the severity of consequences using a scale of 1–5. The study identified 65 potential risks, comprising 15 risks associated with material and equipment inspection, 6 risks related to reinforcement work, 9 risks arising from mould preparation and reinforcement installation, 22 risks associated with concrete casting and curing, and 13 risks related to mould dismantling, quality control, and product storage. The assessment results classified 40 risks as low, 14 as moderate, 6 as high, and 5 as extreme. The extreme risks were primarily associated with the snapping or recoil of PC strands, workers being struck by concrete buckets or precast piles, the manual installation of lifting hooks, and the movement of cranes, excavators, and stacked products. The recommended priority controls include reducing hazardous manual activities, establishing exclusion zones and safety barriers, installing crane guide rails and warning alarms, developing lifting standard operating procedures, providing blind-spot awareness training, installing safety signage, and ensuring the appropriate use of personal protective equipment.

Karakteristik Kuat Tekan Beton Menggunakan Serbuk Besi dengan Bahan Tambah Bestmittel
type: item
description: Concrete, a widely used building material, is prized for its exceptional compressive strength. The field of solid and sustainable infrastructure is seeing swift progress in concrete technology. Numerous ideas and innovations have emerged to enhance concrete quality, including the incorporation of iron powder as a substitute material. This substitution aims to modify concrete's characteristics and improve its strength and hardening time. The research into the compressive strength of concrete using iron powder involved an experimental technique. Findings from this research indicate that a concrete mix containing 7.2% iron powder and 0.7% bestmittel achieved a compressive strength of 28.75 MPa after 28 days. This demonstrates that both iron powder and bestmittel positively influence the compressive strength of concrete. Additionally, the optimal mixture, 7.2% iron powder combined with 0.7% bestmittel, resulted in a compressive strength of 28.75 MPa, reflecting a 3.19% increase compared to standard concrete.

description: The increasing volume of multilayer plastic waste, which is difficult to recycle, has encouraged the exploration of alternative applications in road construction materials. This study aimed to analyze the effect of multilayer plastic waste content on the Marshall characteristics of Asphalt Concrete–Binder Course (AC-BC) mixtures and to determine the optimum plastic content that provides the best mixture performance. An experimental laboratory method was employed using the Marshall test on AC-BC mixtures with an optimum asphalt content (OAC) of 5,15% and multilayer plastic waste contents of 3%, 4%, 5%, 6%, and 7% by asphalt weight. The evaluated parameters included stability, flow, Void in Mix (VIM), Void in Mineral Aggregate (VMA), Void Filled with Bitumen (VFB), and Marshall Quotient (MQ). The results indicated that all multilayer plastic variations produced stability values ranging from 1076 to 1262 kg, flow values from 3.10 to 3.53 mm, and Marshall Quotient values from 309 to 386 kg/mm, all of which satisfied the 2018 Bina Marga General Specifications. The VMA values ranged from 16.57% to 17.57%, while VFB values ranged from 67.43% to 72.39%. The VIM values ranged from 4.57% to 5.72%, with the 5%, 6%, and 7% mixtures slightly exceeding the maximum specification limit. The 4% multilayer plastic content exhibited the best performance, producing the highest stability value of 1262 kg while satisfying all Marshall parameters. These findings demonstrate that multilayer plastic waste has strong potential as an alternative additive in AC-BC mixtures to improve pavement performance while supporting sustainable plastic waste management.

Efektivitas Balikpapan City Trans dalam Menurunkan Kemacetan (Studi Kasus Balikpapan City Trans Rute Koridor B)
type: item
description: Traffic congestion in Balikpapan City continues to increase due to rapid growth of private vehicle ownership, which is not proportional to available road capacity. To address this issue, the Balikpapan City Government has introduced the Balikpapan City Trans (BCT) Corridor B as a mass public transportation service expected to encourage people to shift from private vehicles to public transport. This study aims to analyze the effectiveness of Balikpapan City Trans Corridor B in reducing traffic congestion in Balikpapan City and to evaluate the relationship between BCT operational performance and traffic conditions. This research employed a quantitative descriptive approach through traffic surveys, field observations, public transport operational performance measurements (headway and load factor), and questionnaire distribution to 100 respondents selected using the simple random sampling technique. Data were analyzed based on the Indonesian Road Capacity Guidelines (PKJI) 2023 using traffic volume, road capacity, degree of saturation, level of service, headway, and load factor as the main indicators. The results indicate that the effectiveness of BCT Corridor B remains relatively low. Most road segments recorded degree of saturation values ranging from 0.72 to 0.87 with Level of Service (LOS) D–E, the average headway exceeded 21 minutes, private vehicles remained the dominant mode of transportation, and bus occupancy levels were not yet optimal. Consequently, the contribution of BCT in reducing traffic congestion has not been significant. Therefore, improving service quality through additional buses, shorter headway, optimized operational schedules, and stronger policies encouraging a shift from private vehicles to public transportation is recommended.

Penerapan Value Engineering untuk Efisiensi Biaya Pekerjaan Pelat melalui Alternatif Penurunan Dimensi
type: item
description: Slab work is one of the structural elements of a building that accounts for a significant portion of the total cost, making it a prime candidate for optimization through the application of Value Engineering (VE). This study aims to analyze the application of VE to slab work by exploring alternatives for reducing dimensions to achieve cost efficiency, based on a comparison between the existing conditions and the analyzed alternatives. The study employs a quantitative method using a case study approach that applies the VE phases, including the information phase, functional analysis phase, creative phase, evaluation phase, development phase, and recommendation phase. Research data were obtained from project planning documents, including structural drawings, technical specifications, scope of work, Unit Price Analysis (UPA), and Cost Estimate (CE). The results show that the alternative involving a reduction in dimensions yields a total cost of Rp2.212.119.120,44, which is lower than the existing condition’s cost of Rp2,294,232,385.36, resulting in a cost efficiency of 3,58% with a Value Index of 1.037. These results indicate that the application of VE through the dimensional reduction alternative is capable of increasing the value of the slab work by reducing costs and improving the Value Index.

Analisis Durabilitas Beton dengan Campuran Limbah Kaca terhadap Serangan Sulfat
type: item
description: The continuously increasing use of natural aggregates in concrete production drives the utilization of more environmentally friendly alternative materials, such as waste glass as a partial replacement for fine aggregates. This study aims to analyze the effect of using waste glass on concrete slump and compressive strength, and to compare concrete performance under normal water immersion and sulfuric acid solution immersion. An experimental approach was employed using waste glass variations of 0%, 10%, 20%, and 30% by weight of fine aggregates. Cylindrical specimens (10 cm in diameter and 20 cm in height) were immersed for 21 days in either normal water or a sulfuric acid solution (pH 4), followed by slump and compressive strength testing. The results showed slump values of 6 cm, 5 cm, 7.5 cm, and 7 cm for normal concrete and the 10%, 20%, and 30% waste glass variations, respectively. The highest compressive strength was achieved with the 10% waste glass variation: 27.76 MPa for normal water immersion and 24.27 MPa for sulfuric acid solution immersion. These values represent increases of 62.6% and 29.9%, respectively, compared to normal concrete. Compressive strength tended to decrease with 20% and 30% waste glass content, although the values remained higher than those of normal concrete. Thus, the 10% waste glass variation is the optimum choice for partially replacing fine aggregates, as it yielded the highest compressive strength under both immersion conditions.

Pengaruh Variasi Superplasticizer dan Accelerator terhadap Workability dan Kuat Tekan Beton High Early Strength Berbasis Silica Fume dan Serat Polypropylene
type: item
description: The excessive use of admixtures in High Early Strength (HES) concrete often triggers an imbalance between early strength development and workability. This study aims to analyze the simultaneous effects of four types of admixtures on workability and compressive strength characteristics, as well as to identify the optimal mix composition for HES concrete with a target strength of f'c 40 MPa. The research method employed a quantitative laboratory experimental approach by varying the concentrations of accelerator 1,5%, 2,5%, dan 3,5% and superplasticizer 1,7%, 2,3%, dan 2,6%, while keeping the contents of silica fume 5% and polypropylene fiber 0.025% constant. Testing included the slump flow of fresh concrete and the cylinder compressive strength at ages of 4, 6, 8 hours, and 28 days. The results showed that the highest slump flow value was achieved by the 1.5% accelerator + 2.6% superplasticizer variation at 610 mm, whereas the highest 28-day compressive strength was obtained by the 3.5% accelerator + 1.7% superplasticizer variation at 69.14 MPa. The superplasticizer was proven to enhance workability, while the addition of accelerator reduced slump flow but significantly accelerated hydration and early strength development. Regression analysis indicated a negative correlation y = -0.076x + 108.45, where excessive fresh concrete workability tended to decrease compressive strength. It is concluded that the 3.5% accelerator variation is the most optimal composition to produce massive early compressive strength development without compromising the final concrete quality, making it highly recommended for rapid construction applications and the precast industry.

Pengaruh Beban Lalu Lintas terhadap Sisa Umur Rencana Perkerasan Jalan Menggunakan Metode Bina Marga 2024 Pada Ruas Jalan Swadaya, Mataram
type: item
description: The increase in traffic volume, particularly overloaded heavy vehicles, accelerates pavement deterioration before reaching its design life. This makes urban local roads vulnerable to premature damage due to axle loads exceeding design capacity. This study aims to analyze the effect of traffic loads on the remaining pavement service life on Jalan Swadaya, Mataram City, using the Bina Marga 2024 method. A quantitative approach was employed through analysis of Average Daily Traffic (ADT), Vehicle Damage Factor (VDF), and Cumulative Equivalent Single Axle Load (CESAL) under normal and actual conditions. Results showed cumulative CESAL under normal conditions was 94828 ESA, while under actual conditions it increased to 156175 ESA due to high traffic loads. This caused a significant decrease in Remaining Life (RL), where under normal conditions the pavement could achieve its 10-year design life, while under actual conditions service life was estimated at only 7.33 years, an accelerated reduction of 2.67 years compared to the design life. Under actual conditions, RL decreased to 7% in 2033 and -65% at the end of the analysis period, indicating the pavement had exceeded its design capacity and was no longer structurally feasible. Therefore, controlling overloaded vehicles and implementing heavy rehabilitation or reconstruction are necessary to maintain pavement performance.

Analisis Kondisi Perkerasan Jalan pada Kawasan Rawan Banjir Rob di Kecamatan Sayung Menggunakan Metode PCI dan SIG
type: item
description: The road infrastructure in Sayung District, Demak Regency, has experienced various forms of pavement deterioration in areas prone to tidal flooding, subject to heavy traffic loads, affected by insufficient drainage, and experiencing land subsidence. These factors affect road condition, road safety, and regional economic development, so the assessment of road condition is essential for road condition management and maintenance planning. This study was intended to identify road pavement distress, evaluate pavement condition using the PCI method, and to map the spatial distribution of road damage using a Geographic Information System (GIS) map with ArcGIS 10.8. Using a descriptive quantitative approach, primary data were collected through field surveys, GPS-based coordinate acquisition, and field documentation with secondary data from DEMNAS, road network, and administrative boundary maps. The results indicated nine road damage locations in the arterial and local roads, including alligator cracking, longitudinal cracking, edge cracking, potholes, depressions, raveling, etc. The PCI analysis of the nine observation units has an average value of 69.89, classified as good, representing the average condition of the surveyed road units rather than the entire road network in Sayung District; however, a few road segments require regular maintenance, overlay, or reconstruction. The GIS-based road damage map can show the magnitude of pavement deterioration and can be used to prioritize road maintenance and make decisions for the Government of Demak Regency.

Evaluasi Perkerasan Lentur Menggunakan Metode Bina Marga 2024 di Ruas Jalan Swadaya Kekalik, Mataram
type: item
description: Roads are essential transportation infrastructure that support mobility as well as economic and social activities. The increase in traffic volume, particularly heavy vehicles, can lead to a decline in pavement performance. This study aims to evaluate the condition of flexible pavement on Swadaya Street, Kekalik, Mataram City, using the 2024 Bina Marga Pavement Design Manual. The method used is a descriptive quantitative approach, utilizing Average Daily Traffic (ADT) data as primary data and secondary data obtained from the Public Works Office of Mataram City, including a California Bearing Ratio (CBR) value of 6% and existing pavement structure data from CV Meridian Pasific. The analysis results indicate that the Cumulative Equivalent Single Axle Load (CESAL) for normal load is CESAL4 of 99986 and CESAL5 of 78478, while for actual load it is CESAL4 of 175519 and CESAL5 of 191778. Based on these results, the required pavement thickness consists of a surface layer (AC-WC) of 5 cm, an aggregate base course (Class A) of 22 cm, and an aggregate subbase course (Class B) of 15 cm. The evaluation shows that the existing pavement structure does not meet the requirements of the 2024 Bina Marga standard, particularly in the base layer thickness and the absence of a subbase layer, which may reduce pavement performance. Therefore, adjustments to the pavement structure are necessary to accommodate the design traffic load and improve the service life of the road.

Analisis Kadar Efektif Limbah Serbuk UPVC terhadap Sifat Mekanis Paving Block
type: item
description: The increasing amount of Unplasticized Polyvinyl Chloride (UPVC) waste generated from the construction sector has become an environmental concern, highlighting the need for its reutilization as a value-added construction material. This study aimed to analyze the effect of UPVC powder waste content on the mechanical properties of paving blocks and to determine the effective dosage that provides optimum performance. The research was conducted experimentally at the Civil Engineering Laboratory of Universitas Muhammadiyah Mataram using UPVC powder waste as a partial replacement for fine aggregate at proportions of 0%, 0.25%, 0.50%, 0.75%, and 1.00%, both without and with the addition of 2% accelerator. The specimens consisted of paving blocks measuring 20 cm × 10 cm × 8 cm and were tested at the age of 14 days to evaluate compressive strength and water absorption. The results indicated that increasing the UPVC content tended to reduce compressive strength and increase water absorption. In mixtures without accelerator, the average compressive strength decreased from 19.58 MPa to 14.85 MPa, while water absorption increased from 3.13% to 3.34%. The addition of 2% accelerator improved the performance of the paving blocks, as indicated by a compressive strength of 24.53 MPa and water absorption of 2.18% at the 0.25% UPVC variation. Based on the evaluation of the requirements specified in SNI 03-0691-1996, the recommended effective content of UPVC powder waste was 0.25% of the fine aggregate weight with the addition of 2% accelerator, as it provided the best balance between waste utilization and the mechanical performance of paving blocks. The findings demonstrate that UPVC waste has the potential to be utilized as an alternative material that supports sustainable construction and the circular economy.

Analisis Kinerja Struktur Atas pada Gedung Bertingkat dengan Metode Pushover
type: item
description: Indonesia is a high seismic-risk region due to tectonic plate interactions, particularly along the subduction zone south of Java. The Cirebon area is also influenced by megathrust sources and local faults such as the Baribis Fault, posing significant seismic hazard. This condition requires building structures that are not only strong but also capable of maintaining adequate performance during earthquake loading. This study aims to assess the structural performance of a three-story office building through nonlinear static (pushover) analysis. Modeling was conducted in ETABS, referring to SNI 1726:2019, SNI 1727:2020, and SNI 2847:2019, with dead, live, and lateral loads applied incrementally until the structure reached an inelastic condition. The results show that the structure has adequate lateral capacity, with plastic hinge distribution dominated by the Immediate Occupancy (IO) level. Capacity spectrum transformation using FEMA 440 in the X direction produced stable results, while the Y direction yielded anomalous values requiring further validation. Overall, the structure tends to exhibit Immediate Occupancy performance, although the final global performance level cannot yet be conclusively determined. It is recommended that future analysis revalidate the Y-direction performance point and consider refining the plastic hinge modeling parameters to ensure more reliable performance evaluation results.

Strategic Analysis and Effectiveness of Productivity Improvement in the Construction Sector in Indonesia
type: item
description: Significant and highly complex issues in the construction sector are currently a special and very important concern in reviewing the resolution of ongoing construction conflicts. Poor planning, unclear objectives, ineffective communication, and management and resource issues are the main causes of failure in construction projects. The most common problems are a) unclear inventory, b) irregular workflows, c) lack of employee training and competency development, d) lack of analytical data integration for communication, e) immature planning, unclear environment, poor budgeting, and inadequate risk management, f) unmeasurable targets, and g) a large number of human resources who are not yet competent in their respective fields. This inefficiency will certainly affect construction performance productivity, both from internal and external factors, thereby affecting project implementation, which requires us to provide quality management for the construction project itself and the community. The results showed that inventory management, information technology, training and development, data integration, and competent human resources had positive and significant effects on construction productivity. The proposed SEM model demonstrated an acceptable overall fit.

Development of a Flexible Pavement Overlay Thickness Prediction Model Based on Benkelman Beam Deflection and Equivalent Standard Axle on the Malang Section of the Provincial Road
type: item
description: This study aims to develop a regression-based approximation model for flexible pavement overlay thickness on the Malang provincial road section using Benkelman Beam deflection values and cumulative Equivalent Standard Axle (ESA), with a uniform 15-year design life applied only as the traffic-load projection period. This research utilized a quantitative approach with a correlational and predictive design, applying purposive sampling to historical data from the Department of Public Works and Highways across sixteen road segments. Data were analyzed using the standard Benkelman Beam deflection-based overlay design procedure (Pd T-05-2005-B) to determine the required overlay thickness for each segment, followed by Multiple Linear Regression to quantify the empirical relationship between deflection, cumulative ESA, and overlay thickness. The results show that representative deflection is the dominant and statistically significant predictor of overlay thickness (R² = 0.983; p < 0.001), while cumulative ESA contributes in the hypothesized positive direction. Required overlay thickness across the sixteen analyzed segments ranged from 3.21 cm (Jl. Ir. Soekarno) to 4.54 cm (Wonomulyo-Gubuk Klakah and Jl. Raya Tulungrejo Segmen I); for example, the KM.113+700 - KM.115+405 segment required a 3.87 cm overlay due to a representative deflection of 248.52 mm and cumulative traffic load exceeding 147 million ESA. The regression equation consistently approximated the overlay thickness values obtained from the standard deflection-based calculation across the sixteen analyzed segments. The resulting model should therefore be interpreted as a simplified estimation tool rather than an independently validated predictive model.

Kuat Lentur Panel Dinding Non-Struktural Berbasis Limbah Karet Ban Bekas
type: item
description: Waste from used tires is an ever-increasing problem. As the volume of this waste grows, there is a need for sustainable construction material innovations that optimize the use of recycled waste while maintaining mechanical performance. However, incorporating used tire rubber into materials typically reduces flexural strength, thereby limiting its application in wall panels. This study aims to determine the flexural strength of wall panels made from used tire rubber and to assess performance improvements achieved by adding Glass Fiber Reinforced Concrete (GRC). Test specimens consisted of mixtures containing used tire rubber, both with and without GRC. The wall panels underwent a laboratory curing process prior to flexural strength testing. Additionally, failure patterns and crack propagation were observed to identify the failure mechanisms associated with each specimen variation. The results indicate that the addition of GRC increased the average flexural stress at maximum load (flexural strength) from 1.61 MPa to 2.57 MPa. All GRC-reinforced panels exhibited relatively uniform crack patterns, characterized by dominant vertical cracks developing near the mid-span. This indicates that the failure mechanism was dominated by flexural stress. The presence of GRC also retarded crack propagation through a crack-bridging mechanism, thereby enhancing fracture resistance and the panel's load-bearing capacity.

Transformasi Simpang Tak Bersinyal Menjadi Simpang Bersinyal Untuk Optimalisasi Kinerja Lalu Lintas pada Simpang UMMAT
type: item
description: The continuous increase in population and the number of vehicles in Mataram City, along with the growing traffic volume, has become one of the major transportation issues experienced in many regions of Indonesia. One such case occurs at the UMMAT four-legged intersection in Mataram City. This intersection experiences high traffic activity due to its location within an area dominated by educational institutions, commercial activities, and government offices, resulting in the potential for traffic delays, vehicle queues, and traffic conflicts. This study aims to evaluate the changes in intersection into a signalized intersection based on the Indonesian road capacity guidelines (PKJI) 2023. The study employed a quantitative method through geometric and traffic volume surveys, followed by an analysis of intersection performance parameters, including capacity, degree of saturation, delay, and queue length. The analysis results indicate that, under the existing unsignalized condition, the intersection capacity was 3,524 pcu/h, with a degree of saturation of 0.83 and an average delay of 13.96 s/pcu. After the implementation of the traffic signal (APILL) with an optimal cycle time of 66 second, the degree of saturation at each approach decreased to 0.67. These findings indicate that the implementation of Traffic Signal Device (APILL) was able to reduce the degree of saturation, although vehicle delay increased due to signal phase-based traffic control. Therefore, the implementation of Traffic Signal Device (APILL) effectively reduced traffic saturation at the intersection.

Analisis Sistem Jaringan Irigasi Air Tanah Desa Sumberanyar dengan Menggunakan Software EPANET 2.2 (Studi kasus: Daerah Sumur dalam Banyuwangi 198 Desa Sumberanyar, Wongsorejo, Banyuwangi)
type: item
description: Groundwater is used for various purposes, including in the agricultural sector. In this sector, groundwater plays an important role as a source of irrigation for agricultural land, especially during the dry season, when the water supply from the surface is insufficient for irrigation needs. The groundwater irrigation network is a channel system that flows groundwater from the pump building to the rice fields to be irrigated. This study aims to determine the irrigation water and piping needs in SDBW 198 Sumberanyar. The research method used is quantitative. The results of the calculation of the irrigation water needs of SDBW 198 per plot of land showed that the total irrigation water requirement was 39.49 liters/second. The discharge requirement of 39.49 liters/second is the sum of the needs of all plots if they are irrigated simultaneously. Meanwhile, the available pump discharge is 33.84 liters/second. Therefore, irrigation services are not planned simultaneously, but are carried out in turns based on plot groups so that the discharge requirements in each service period do not exceed the pump capacity. The design of the piped irrigation network can irrigate 23.03 hectares of rice fields using 6-inch PVC pipes for pipes P2, P6, P4, P5, P6, P7, P9, P12, 4-inch pipes for pipes P3, P5, P13, P14, P19, and 2-inch pipes for pipes P8, P10, P11, P15, P16, P17, and P18. The highest headloss simulation results were 6.05 m/km for pipe P2 and 8.13 m/km for pipe P6. Because the headloss in pipes P2 and P6 did not meet standards, two air valves had to be installed. The highest pressure simulation results occurred at J-TO1 with a value of 60.93 meters of water, while the lowest pressure was at J-17 with a value of 20.07. Therefore, the pressure simulation results using EPANET 2.2 software met all required criteria.

Keterlambatan Pembongkaran dan Pemasangan Lift Baru Menggunakan Metode House Of Risk (HOR)
type: item
description: Delays in construction projects, particularly in dismantling and installing elevators, can significantly impact project time, cost, and quality. This study aims to analyze the factors causing delays in the project of dismantling the old elevator and installing a new one at a building owned by PT. X. The House of Risk (HOR) method is used to identify and prioritize risk agents and to develop effective mitigation strategies. Data were collected through interviews and focus group discussions (FGD) with project stakeholders, including the owner, contractor, building manager, and supervisory consultant. The HOR Phase 1 (HOR1) analysis identified 15 delay agents and determined three with the highest Aggregate Delay Potential (ADP): delayed project commencement, imported materials, and delay in dismantling the old elevator. HOR Phase 2 (HOR2) was then used to formulate the most effective mitigation actions based on the ratio of effectiveness to implementation difficulty. The results show that the three main recommended mitigation strategies are: rescheduling project activities, accelerating material procurement, and involving a supervisory consultant from the beginning of the project. Implementing these strategies is expected to significantly reduce the risk of delays and enhance the efficiency of future project execution.

description: Road maintenance is an important aspect in maintaining road service function, user comfort, and traffic safety. Road damage that is not evaluated promptly can reduce the performance of road segments and disrupt community activities. This study aims to assess the level of damage on the Sugio–Kedungpring Road segment as a basis for determining an appropriate road maintenance program. The method used in this study is the 1990 Bina Marga method, with data obtained from visual road damage surveys and daily traffic volume surveys. The road segment studied has a length of 1,000 meters and was divided into 10 observation segments, each measuring 100 meters. The results show that the Average Daily Traffic (ADT) value on the Sugio–Kedungpring Road segment is 337.20 passenger car units/day, which classifies the road as class 3. Based on the damage assessment recapitulation, the total damage score was 22, resulting in a road condition score of 8. The priority order calculation produced a score of 6, indicating that this road segment falls into the periodic maintenance program category. Therefore, planned maintenance is required to prevent further deterioration and maintain the road service function.

Kinerja Jaringan Irigasi Sadan Menggunakan Metode IKSI
type: item
description: Irrigation networks are vital infrastructure in supporting agricultural productivity and food security. One of the strategic networks in Pasuruan Regency is the Sadan Irrigation Network, which serves an agricultural area of 322 km² with the support of a main weir, primary, secondary, and tertiary canals, as well as complementary structures. Over time, the network’s performance has declined due to channel damage, sedimentation, aquatic weed growth, and the lack of maintenance and farmer participation. These conditions have resulted in uneven water distribution and reduced irrigation efficiency. This study aims to evaluate the performance of the Sadan Irrigation Network using the Irrigation System Performance Index (ISPI/IKSI) method. Primary data were collected through field observations, technical measurements, and interviews with farmers and irrigation managers, while secondary data were obtained from related agencies. The analysis was carried out using a quantitative-descriptive approach based on the guidelines of the Directorate General of Water Resources, assessing aspects of physical infrastructure, water distribution, operation and maintenance, institutional arrangements, and farmer participation. The results show that the total ISPI value of the Sadan Irrigation Network is in the range of 65–70, classified as moderate. Physical infrastructure and conveyance canals are the lowest-performing components due to structural damage and sedimentation, while complementary structures are relatively good. Water distribution remains suboptimal due to illegal tapping and canal leakage, while operation and maintenance activities are incidental rather than routine. Farmer participation through Water User Associations (P3A) is still limited to communal work and not yet well-organized. In conclusion, the Sadan Irrigation System is still functioning but not optimally effective or efficient. Infrastructure improvements, routine maintenance, and strengthened institutions with gr…

Hubungan Lalu Lintas Harian Rata-Rata (LHR) dan Proporsi Kendaraan Berat Terhadap Surface Distress Index (SDI)
type: item
description: The Betung – Palembang City Boundary Road segment is part of the primary arterial corridor of the East Trans-Sumatra route, which plays an important role in supporting regional logistics connectivity. The high intensity of freight transportation along this corridor increases the frequency of heavy vehicle movements and generates repeated loading on flexible pavements, which may accelerate pavement surface deterioration. Based on Average Daily Traffic (ADT) data from the South Sumatra National Road Implementation Agency (BBPJN) in 2024, the traffic volume on this segment reaches approximately 52,073 vehicles per day with a heavy vehicle proportion of about 37%. Meanwhile, the traffic survey conducted in this study recorded an average of approximately 25,000 vehicles per day with a heavy vehicle proportion of about 12%. This study aims to analyze the characteristics of ADT and heavy vehicle proportions, evaluate the level of pavement surface distress using the Surface Distress Index (SDI) method, and examine the relationship between traffic variables and pavement surface deterioration. The research method involved field surveys consisting of traffic counts and visual pavement inspections per segment. SDI values were calculated based on the type, extent, and severity of pavement distress. The relationship between variables was analyzed using multiple linear regression. The results show that segments with higher traffic volumes and greater proportions of heavy vehicles tend to have higher SDI values, indicating moderate to poor pavement conditions. The regression model produced a coefficient of determination (R²) of 0.8383, indicating that approximately 83.83% of the variation in SDI values can be explained by traffic volume and vehicle composition variables. Partially, large buses (p = 0.0438) and heavy trucks (p = 0.0417) were found to significantly influence the increase in SDI values. Therefore, traffic volume and heavy vehicle composition data can be recommended as…

Evaluasi Kompetensi Pengawas Lapangan Berdasarkan SKKNI dalam Pelaksanaan Proyek Konstruksi di Dinas Pekerjaan Umum dan Penataan Ruang Kabupaten Sijunjung
type: item
description: Field supervisors play a crucial role in ensuring the successful implementation of construction projects, particularly in controlling the quality, time, and cost of work. The competence of field supervisors is a key factor in ensuring that the construction process runs in accordance with technical specifications, occupational safety standards, and applicable contract provisions. Therefore, competency standards referring to the Indonesian National Work Competency Standards (SKKNI) are needed as a reference in improving the quality of human resources in the construction sector. This study aims to identify competency factors that field supervisors must possess, measure the level of conformity of these competencies to the SKKNI, and analyze the relationship between competencies in the Indonesian National Qualification Framework (KKNI) levels 4–6 and 7–9 in construction projects at the Public Works and Spatial Planning Agency of Sijunjung Regency. This study uses a quantitative approach with a survey method by distributing questionnaires to 100 respondents consisting of contractors, supervisory consultants, and technical officials involved in the implementation of construction projects. Data analysis was carried out through validity and reliability tests, factor analysis, and Structural Equation Modeling (SEM). The results of the study indicate that field supervisor competency is formed from three main dimensions, namely technical and managerial competency, social and operational field competency, and professional work attitude. Of the 36 competency indicators analyzed, 72.22% are in the appropriate category and 27.78% are in the very appropriate category according to the SKKNI standards. In addition, the results of the structural analysis show that competency at KKNI levels 4–6 has a significant effect on competency at KKNI levels 7–9 with a coefficient of determination (R²) of 0.658. These findings indicate that the competency system is hierarchical and progressive and…

Analisis Daya Dukung Tanah Dasar pada Ruas Jalan Sarirejo–Jatirembe
type: item
description: Roads are an essential land transportation infrastructure that supports social and economic activities within the community. The condition of the subgrade is one of the primary factors influencing pavement strength and service life, particularly in areas with high moisture content such as agricultural regions. The Sarirejo–Jatirembe Road in Lamongan Regency has experienced various forms of pavement distress, including cracking, settlement, and surface undulations, which are suspected to be associated with low soil bearing capacity This study aims to evaluate the bearing capacity of the subgrade along the Sarirejo–Jatirembe Road based on DCP testing, laboratory CBR testing, standard compaction testing, and Atterberg limits using a quantitative descriptive approach. Data were collected through Dynamic Cone Penetrometer (DCP) testing to determine field California Bearing Ratio (CBR) values, as well as laboratory tests including CBR, standard compaction, and Atterberg limits. The results indicate that the average field CBR value was 6.23%, with most values ranging from 2.29% to 5.74% and a maximum value of 18.67%, suggesting low to moderate soil bearing capacity. Laboratory CBR values were 2.07% at 10 blows, 2.33% at 25 blows, and 7.92% at 56 blows. Compaction test results showed an optimum moisture content of 18.61% and a maximum dry density of 1.579 g/cm³, while the Atterberg limits were 36.67% liquid limit (LL), 28,36% plastic limit (PL), and 8,30% plasticity index (PI). Based on these findings, the subgrade soil at the study location is classified as having low to moderate bearing capacity, contributing to pavement deterioration and requiring improvement measures to enhance pavement performance.

description: The Road Jendral Sudirman area in Palembang City is one of the main areas that is the center of economic, social, and transportation activities. Along this road there are many shopping centers, office buildings, public facilities, and various other business places. The high density of activity causes a high volume of vehicles passing through and stopping to park on the roadside. This causes serious problems such as traffic congestion and disruption of vehicle flow. This study aims to analyze the need for parking spaces that can accommodate vehicles parked on Jalan Jendral Sudirman so that there are no more vehicles parked illegally on the roadside. The methods used include field surveys, parking needs analysis, Parking Accumulation, Parking Volume, and Parking Space Needs. The results obtained, for the need for parking space with a land area of 8,400 m2 as many as 540 parking spaces for cars and 1,440 parking spaces for motorcycles with a volume of 537 cars and a volume of 713 motorcycles. This shows that parking facilities are an effective solution to reduce illegal parking and improve traffic flow in the area

Sifat Mekanik Kuat Tekan Beton Menggunakan Limbah Beton Sebagai Subtitusi Agregat Kasar
type: item
description: Concrete waste from construction activities is often simply discarded without being reused, even though this material still has the potential to replace coarse aggregate in concrete. Efforts to utilize this waste are in line with the concept of sustainable construction that emphasizes the principles of reducing, recycling, and reusing. In this study, concrete waste was utilized as a substitute for coarse aggregate with variations of 25%, 50%, and 75%, and an additive in the form of silica fume was added at 5%. Compressive strength tests were conducted at the ages of 7, 14, and 28 days to meet the development of concrete strength, while slump tests were used to assess workability. The test results showed that the mixture with 50% substitution produced the most optimal compressive strength, namely 25.34 MPa at the age of 28 days. Conversely, at 75% substitution, there was a significant decrease in strength. In addition, the slump value did not decrease linearly with the content of concrete waste—it approached the normal concrete value at 50% substitution before dropping sharply at 75%, indicating reduced workability at higher substitution levels. These findings confirm that the use of concrete waste as coarse aggregate can be an environmentally friendly alternative in industrial construction, with all its compositions being precisely regulated to meet technical standards. Further studies are still needed to explore the use of other additional materials to improve the quality of recycled concrete.

Penggunaan Metode Time Cost Trade Off Berbasis Algoritma Genetika
type: item
description: One of the main challenges in construction project management is balancing implementation duration and total project cost. Time-Cost Trade-Off (TCTO) is a method used to analyze the relationship between time and cost in an effort to find the most efficient combination. This study aims to present the application of the TCTO method with a genetic algorithm (GA) approach as an optimization technique. The analysis results indicate that accelerating work duration can affect project costs. Analysis of direct and indirect cost graphs using the Time-Cost Trade-Off method demonstrates that accelerating time causes an increase in direct costs and a decrease in indirect costs, thus requiring a balance between the two to achieve project efficiency. These results demonstrate that this approach is capable of simultaneously presenting efficient alternative solutions and can be used as a reference for decision-making in the project planning stage. Consequently, the Genetic Algorithm (GA) has proven to be a practical and applicable method for solving Time-Cost Trade-Off problems in construction projects.

Evaluasi Kapasitas Penampang Drainase Jalan Johar – Lamaran Karawang
type: item
description: The rapid expansion of residential, commercial, and industrial areas along the Johar – Lamaran road segment in Karawang Regency has increased impervious surface coverage and surface runoff, resulting in recurring flooding despite the presence of existing drainage channels. This study aims to evaluate the capacity of the existing drainage channels against the 50-year return period design flood discharge and to formulate an appropriate channel redesign. The design flood discharge was calculated using the Rational Method with rainfall intensity derived from the Generalized Extreme Value (GEV) distribution, while channel capacity was analyzed using the Manning formula. Evaluation of nine channel segments showed that the design discharge (0.518–6.579 m³/s) exceeded the existing capacity (maximum 1.87 m³/s) in all segments, indicating that none of the existing channels can accommodate the design flood. Channel redesign using an economic dimensioning approach produced dimensions sufficient to meet the required capacity, whereas the conditional dimensioning approach resulted in unrealistic channel depths for several segments given actual site conditions. All segments were identified as operating under subcritical flow conditions. This study recommends a comprehensive channel redesign incorporating technical modifications such as tiered or closed channels, along with further study using numerical models such as SWMM or HEC-HMS for broader-scale application.

Manajemen Konstruksi di Kawasan Kritis: Studi Kasus Proyek Pembangunan Gedung Kedokteran Nuklir
type: item
description: The construction of the Nuclear Medicine Building at Dr. Soedarso Regional General Hospital, Pontianak, involves a complex special structural system, yet experienced delays and several changes during implementation, risking cost and schedule overruns. This study aims to evaluate and analyze construction management in the project across five key aspects—cost, time, human resources, materials, and risk—by comparing initial planning with actual field conditions. A descriptive quantitative method was applied, using primary data from field observations and market price surveys, along with secondary data including the Budget Plan (RAB), Unit Price Analysis (AHSP), shop drawings, Terms of Reference (RKS), and Construction Safety Plan (RKK), analyzed through the Implementation Budget Plan (RAP), bar-chart scheduling, and the HIRARC method. Results show that the RAP, at IDR 8,756,988,074.05, was more cost-efficient than the RAB of IDR 12,215,041,500.12, yielding savings of IDR 3,458,053,426.07, equivalent to a 28% efficiency gain. The project was scheduled over 90 working days (15 weeks), with peak workload in week 12 and the highest labor demand of 980 workers in week 10, while structural work was identified as posing the highest safety risk. Based on these findings, it is recommended that cost control be based on actual market surveys, that scheduling anticipate peak workload periods, that labor allocation remain flexible during critical weeks, and that occupational safety supervision be strengthened particularly for structural work to ensure overall project efficiency and safety

Analisis Substitusi Abu Ampas Tebu dan Garam terhadap Karakteristik Mekanis pada Stabilitas Tanah Laterit
type: item
description: Soil stabilization is a technique commonly applied in construction projects to improve soil strength so that it can adequately support structural loads. In this study, lateritic soil was stabilized using additives in the form of sugarcane bagasse ash (SBA) and coarse salt. A quantitative research approach was employed through a series of laboratory tests. The mixture composition consisted of 3% SBA, while the coarse salt content was varied at 4%, 8%, 12%, 16%, and 20%. The California Bearing Ratio (CBR) test results for the natural soil showed values of 15.00% at 2.5 mm penetration and 19.11% at 5.0 mm penetration with 56 blows. After the addition of SBA and salt, the CBR values exhibited fluctuations. The highest CBR values were obtained from the mixture containing 3% SBA and 8% coarse salt with 56 blows, reaching 26.00% at 2.5 mm penetration and 30.22% at 5.0 mm penetration, indicating a significant improvement in soil bearing capacity. In contrast, the lowest CBR values were observed in the mixture of 3% SBA and 12% coarse salt with 25 blows, yielding only 2.40% at 2.5 mm penetration and 2.78% at 5.0 mm penetration, which indicates a substantial reduction in soil strength. The unconfined compressive strength (UCS) test results showed that the natural soil possessed the highest strength, with a maximum value of 5.88 kg/cm². After stabilization, the UCS values generally decreased, although the mixture with 8% salt still produced values close to those of the natural soil. However, increasing the salt content beyond 12% resulted in a significant decline in soil strength.

Evaluasi Retrofitting Kolom Gedung A RSPTN Jember Menggunakan Metode Respons Spektrum Berbasis Software
type: item
description: Indonesia is located at the convergence of active tectonic plates, resulting in high seismic activity. This condition requires critical facilities, such as Building A of the State University Hospital (RSPTN) at the University of Jember, to maintain structural performance that ensures safety and continued functionality after an earthquake. As buildings age and seismic evaluation standards evolve, assessment of column elements is necessary to determine structural safety and strengthening needs. This study aims to evaluate the seismic performance of the columns in Building A of RSPTN Jember based on ASCE/SEI 41-17, identify columns requiring strengthening, and analyze the improvement in structural performance after retrofitting using the concrete jacketing method. A quantitative approach was employed through structural analysis using SAP2000 V.14 and the response spectrum method in accordance with SNI 1726:2019, utilizing existing structural data, loading data, material properties, and geotechnical investigation results. Performance evaluation covered the fundamental period, base shear, inter-story drift, and column capacity per ASCE/SEI 41-17. Results showed a maximum inter-story drift of 28.275 mm (X-direction) and 6.666 mm (Y-direction), both within allowable limits, yet several columns failed to meet performance criteria. Applying concrete jacketing increased column axial and nominal moment capacity (Pnk = 86,481 kg; Mnk = 6,392,998 kg-cm), exceeding the factored demand forces and improving overall structural performance. This retrofitting approach is recommended as a practical strengthening alternative for similar hospital buildings to meet seismic resistance requirements.

Implementasi Metode PDM dan Pert pada Proyek Pembangunan Kantor Dinas Lingkungan Hidup (DLH) Kota Samarinda
type: item
description: Uncertainty in project duration caused by weather conditions, resource availability, and labor productivity remains a common challenge in the construction industry, requiring a scheduling method capable of minimizing the risk of delays. This study aims to analyze the critical path and the probability of project completion in the construction project of the Environmental Agency (DLH) Office Building of Samarinda City using the Precedence Diagram Method (PDM) and the Program Evaluation and Review Technique (PERT). The project under study has a building area of 450 m² with a planned implementation duration of 180 calendar days. The research data were obtained from project documents and questionnaires distributed to 30 respondents with experience in the construction sector. The analysis was conducted using Microsoft Project 2019 to develop the project network and identify activities on the critical path. The results of the PDM analysis indicated that 53 out of 205 total work items were critical activities, with an estimated minimum project completion duration of 158 days; these activities directly affect the overall project completion time. Subsequently, the PERT method was employed to estimate the optimistic, most likely, and pessimistic durations of each critical activity and to determine the probability of completing the project within the planned schedule. The results showed that the probability of completing the project within 180 calendar days was 81%, indicating a high level of confidence consistent with the project's actual on-time completion in the field. The PDM method provides information on activities within the project's critical path, while the PERT method provides information on the probability of project completion according to the planned schedule, so the results of this analysis can serve as a reference for evaluating and controlling construction project schedules. Future research is recommended to consider a time-cost trade-off analysis on critical ac…

Sidewalks As Contested Space: Spatial Analysis of Walkability and Street Vendor Occupation Patterns in The Central Business District of Medan City
type: item
description: Sidewalks in the city centers of developing countries frequently become arenas of spatial contestation between walkability principles and informal street vendor (pedagang kaki lima/PKL) activities. However, academic studies that address this phenomenon through a spatial typology lens within the discipline of architecture and urban design remain limited, particularly in Medan City. This study aims to examine the spatial typology of sidewalks in central Medan, analyze the spatial occupation patterns of street vendors as a phenomenon of space production, and formulate inclusive design principles based on a synthesis of precedents from other cities. The research employs a descriptive-evaluative qualitative approach through precedent analysis and literature review, drawing on secondary data comprising Medan City’s zoning regulation (Regional Regulation No. 5/2022), technical standards from Ministerial Regulation PUPR No. 03/PRT/M/2014, and international and national journal articles published between 2021 and 2026. The analysis applies walkability frameworks (Speck; Gehl; Whyte) and Lefebvre’s production of space theory, reinforced by contemporary studies on counter-space. Findings reveal that the spatial typology of sidewalks in Medan is spectral in nature, encompassing both frontage-based occupation and main-circulation-path occupation, each requiring distinct design strategies. A synthesis of precedents from Hanoi, Bandung, Yogyakarta, and Palopo yields four spatial solution typologies – targeted relocation, micro-spatial demarcation, flexible time-based zoning, and partial shared space – which can be differentially adapted according to the spatial character of each corridor segment. This study contributes to the discipline of architecture and urban design by offering a conceptual framework previously absent from the existing literature on street vendors in Medan City, while recommending that spatial zoning policies be integrated with inclusive design principles that …

description: Road infrastructure plays a vital role in supporting public mobility and economic activities. The Simpang Teritep–Muntok road section is a strategic route in West Bangka Regency that is heavily traversed by heavy vehicles, making it prone to accelerated damage due to overloading. This study aims to analyze the effect of overloading on the reduction of the pavement design life on that specific road section. The method used is a quantitative approach with calculations based on the 2024 Pavement Design Manual (Manual Desain Perkerasan/MDP 2024) utilizing Average Daily Traffic (ADT/LHR), Vehicle Damage Factor (VDF), Equivalent Single Axle Load (ESAL), and Cumulative ESAL (CESA) data. ADT is the average traffic volume passing through a specific point or cross-section of a road within a single day (24 hours). VDF is a coefficient that indicates the level of damage caused by a single or multiple axle load passes to the pavement structure, relative to the standard axle load. ESAL is a unit used to convert various types of different vehicle axle loads. Primary data were obtained through field surveys, while secondary data were sourced from the Public Works Department of Bina Marga, West Bangka. The results indicate that overloaded vehicles contribute to a significant increase in the VDF value, thereby increasing the cumulative ESAL value and accelerating structural pavement damage. This condition causes the road design life to decrease from its intended service life. In conclusion, overloading has a direct impact on the reduction of pavement life, highlighting the need for vehicle load monitoring and more optimal road maintenance planning.

Karakteristik Paving Block Akibat Penambahan Serat Microfiber terhadap Kuat Tekan
type: item
description: Paving block is a cement-based material produced through the compaction of a mixture of constituent materials, with or without the addition of additives. Paving block has a brittle characteristic, making it stronger in resisting compressive loads compared to tensile or flexural loads, which causes it to be susceptible to cracking. The addition of microfiber fibers can improve the mechanical properties and durability of Paving Block by reducing plastic shrinkage cracks through a micro-binding mechanism. This research employed an experimental method conducted at the Concrete Laboratory, Faculty of Engineering, University of Palembang, for four months. The specimens were cube-shaped with dimensions of 5 cm × 5 cm × 5 cm, consisting of three specimens for each variation of microfiber fiber content. The results of the Paving Block compressive strength test show variations in the compressive strength values of each specimen. The PBM-0 specimen achieved a compressive strength of 103 kg/cm², while the PBM-1 specimen increased to 107 kg/cm². Furthermore, the PBM-2 specimen reached a compressive strength value of 111 kg/cm², followed by PBM-3 with the highest value of 114 kg/cm². However, the PBM-4 specimen showed a slight decrease in compressive strength to 110 kg/cm², and a further decrease occurred in PBM-5 with a compressive strength value of 97 kg/cm². Based on these results, it can be concluded that variations in the mixture composition of the specimens affect the compressive strength of Paving block.

Studi Eksperimental Pengaruh Substitusi Sebagian Pasir Malang (Pasir Vulkanik) dengan Abu Batu terhadap Kuat Tekan Beton Mutu Fc’20 MPa
type: item
description: Concrete is one of the most widely used construction materials due to its high compressive strength, good durability, and the availability of its constituent materials. However, the increasing demand for natural fine aggregate has led to excessive exploitation of natural resources, creating environmental concerns. Therefore, alternative materials are needed to partially replace fine aggregate. This study aimed to analyze the effect of partially substituting fine aggregate with Malang Sand and Stone Dust on the compressive strength of concrete with a design strength of 20 MPa and to determine the optimum mixture proportion. The research employed an experimental method conducted at the Civil Engineering Laboratory of Universitas Islam Lamongan UNISLA. Cylindrical concrete specimens measuring 15 cm × 30 cm were prepared using the mix design method based on SNI 03-2834-2000. The substitution levels of fine aggregate were 5% (2.5% Malang Sand + 2.5% Stone Dust), 10% (5% Malang Sand + 5% Stone Dust), and 15% (7.5% Malang Sand + 7.5% Stone Dust), with normal concrete used as the control mixture. The results showed that the average compressive strength of normal concrete was 20.52 MPa, while the 5%, 10%, and 15% substitution mixtures achieved compressive strengths of 19.85 MPa, 18.47 MPa, and 17.50 MPa, respectively. Increasing the substitution percentage of Malang Sand and Stone Dust tended to reduce the compressive strength of concrete. The 5% substitution mixture produced the best performance because its compressive strength was the closest to both the normal concrete and the target design strength of 20 MPa.

Analisis Identifikasi Bahaya dan Penilaian Risiko dalam Menentukan Tingkat Risiko pada Pekerjaan Perbaikan Tanah dengan Metode Vacuum Consolidation
type: item
description: Vacuum Consolidation is one of the effective soft soil improvement techniques; however, its implementation involves the use of heavy equipment, high-pressure instruments, and complex geotechnical working environments, which may generate various Occupational Health and Safety (OHS) hazards. This study aims to identify potential hazards, assess risk levels, and formulate control measures for soil improvement works using the Vacuum Consolidation method. The analysis was conducted using the Hazard Identification and Risk Assessment (HIRA) approach based on a standard risk assessment matrix. Data were collected through field observations and literature reviews. The hazard identification results revealed several critical potential incidents, including unstable Prefabricated Vertical Drain (PVD) hydraulic rigs that may overturn on soft ground, workers coming into contact with uninsulated live electrical cables, and unauthorized contact with pumps or electrical control panels that may result in fatal electric shock. The initial risk assessment classified the identified hazards into low, medium, high, and extreme risk categories. Through the implementation of mitigation measures encompassing engineering controls, administrative controls, and strict compliance with Personal Protective Equipment (PPE) requirements, the residual risk level is projected to be reduced to an acceptable level. This study is expected to serve as a guideline for the implementation of Occupational Health and Safety Management Systems in similar geotechnical projects to minimize workplace accidents and optimize project productivity.
