Abstract

Road surface degradation poses significant risks to service quality and traffic safety, necessitating systematic evaluation for effective rehabilitation. This study assessed the condition of the Weleri-Sukorejo road segment using the Pavement Condition Index (PCI) method and safety inspections to formulate targeted rehabilitation strategies. The 12 km road was divided into six segments for visual surveys, with PCI calculations following ASTM D6433 guidelines. Results revealed PCI values ranging from 28 (very poor) to 99 (excellent), averaging 64.5 (fair). Critical findings identified severe damage in segments 0+000–2+000 (PCI 35) and 2+100–4+000 (PCI 28), dominated by potholes (29%) and polished aggregate (24%), requiring immediate structural intervention. Moderate degradation in segments 10+100–12+000 (PCI 64) and 4+100–6+000 (PCI 72) highlighted the need for periodic maintenance, while high-PCI segments (6+100–10+000) warranted routine upkeep. Key contributing factors included overloading, substandard materials, and inadequate drainage. Recommendations prioritize structural rehabilitation, material standardization, and preventive maintenance to enhance road safety and longevity. The study contributes by providing a technical evaluation approach based on PCI data to support more accurate, measurable, and safety-oriented road rehabilitation planning on national road segments.

Abstract

High rainfall and changes in land cover occurring in the Batang Tabir sub-watershed have an impact on surface runoff and increased river flow, triggering flooding and causing road access to be submerged and damage to infrastructure around the river. Therefore, it is necessary to review the flood flow design calculations in the Batang Tabir Sub-Watershed to assess the potential magnitude of flood flows and establish the parameters required for water infrastructure planning. The methods commonly used for flood flow calculations are the Rational Method and the Nakayasu HSS Method. These methods are preferred due to their simplicity, as they only require river data and rainfall data. The selection of an appropriate method for calculating flood discharge must be validated with measured river discharge data. This study aims to determine the design flood discharge method that can be applied to the Batang Tabir Sub-Watershed. This study was conducted by comparing the flood discharge of the Rational and HSS Nakayasu methods with measured flood discharge using frequency distribution based on relevant statistical parameters. The results of the flood discharge calculations using the Rational method for a return period of 2–100 years are closer to the measured flood discharge, with the Rational method yielding a flood discharge of 494.05–1,385. 48 m³/s, the flood discharge using the Nakayasu HSS method for a return period of 2–100 years was 769.32–2,157.41 m³/s, and the measured flood discharge for a return period of 2–100 years was 375.22–1,337.44 m³/s. The validation and evaluation results show that the smallest error value (VE) is found in the Rational method, which is 9%, with the Nash Sutcliffe Efficiency (NSE) value falling into the very good category at 94%. Meanwhile, the Nakayasu HSS method yields the largest error value (VE) at 69%, and the NSE value falls into the unsatisfactory category at 17%. Therefore, the Rational method has a better level of suitability and can be used as a reference in infrastructure planning in the Batang Tabir Sub-Watershed.

Abstract

Rapid development in the construction sector is strongly influenced by its crucial and efficient functions. This drives the construction industry towards better integration. Currently, advances in technology and communication play an important role in overcoming various challenges, one of which is through the implementation of Building Information Modeling (BIM). This approach supports more integrated design and construction processes, resulting in higher efficiency. A primary challenge in construction service provision is the discrepancy in work volume, which can affect project success. By using Autodesk Revit 2025, the implementation of 5D BIM for material Quantity Take-Off can provide higher accuracy in volume estimation. In its implementation, data is processed using Autodesk Revit 2025 BIM software integrated with Microsoft Excel for further analysis. The results show that total volume calculations using Autodesk Revit are more precise compared to conventional methods. The volume of concrete work based on BIM is 2,005.35 m³, which is 83.31 m³ lower than the conventional method at 2,088.66 m³. Meanwhile, the reinforcement volume based on BIM is 354,670.98 kg, which is 29,024.91 kg lower than the conventional method at 383,695.89 kg. The contribution of this research is the demonstration that the implementation of 5D BIM using Autodesk Revit 2025 significantly improves the accuracy of structural work volume calculations compared to conventional methods, thereby helping to reduce volume discrepancies in construction projects and enhancing the reliability of material quantity planning.

Abstract

The PKU Muhammadiyah UNIMUDA Sorong Hospital, located in Sorong Regency, West Papua, is currently in its initial phase of construction. This study aims to analyze the clean water demand, design the water distribution (plumbing) system, and estimate the construction costs of the plumbing and reservoir systems for the hospital's main building. The research method used is descriptive quantitative, utilizing primary data from field observations and secondary data such as architectural plans and technical standards. The water demand calculation is based on the Unit Plumbing Fixture Load (UPFL) method, referring to the Indonesian National Standard (SNI) 8153:2015. The results indicate that the water distribution system is designed by considering the reservoir capacity, pipe dimensions, minimum water pressure, and flow efficiency to support the hospital's operational needs sustainably. Cost estimation is presented in the form of a Bill of Quantities (BoQ), covering key components such as piping, pumps, and plumbing accessories. This research contributes as a technical reference for planning clean water systems in multi-story healthcare facilities and supports efficient and sustainable water management efforts in the West Papua region.

Abstract

During the construction process of the Sidoarjo Funeral Home, there were problems related to material flow that eventually caused the work-time to deviate from the planned schedule. This condition indicates the necessary analysis and evaluation of risks that may appear due to material supply chain disruptions. This study aims to identify events and causes of risk in the material supply chain flow using the Supply Chain Operation Reference (SCOR) approach, as well as to formulate and prioritize effective and realistic risk mitigation strategies to improve Supply Chain Management (SCM) performance in the project. After identifying the risks, an analysis of risk causes was conducted, followed by the design of mitigation strategies. The prioritization of mitigation strategies was based on their effectiveness and implementation difficulty. Tshe study identified 19 risk events and 20 risk causes that affected the supply chain flow. Eight mitigation strategies were proposed to address nine dominant risk causes, including developing and implementing SOPs as a communication system, enhancing material security protection, imposing penalties on relevant parties, creating an integrated system, improving coordination and communication with suppliers, establishing agreements with external parties, conducting employee training, and implementing a more rigorous worker selection process.

Abstract

The utilization of coal combustion waste, particularly fly ash (FA), as an additive in the base course of mining haul roads has the potential to enhance the mechanical performance of the material while supporting sustainable construction practices. This study aims to analyse the effect of fly ash on Maximum Dry Density (MDD) and Optimum Moisture Content (OMC) in a composite material of fly ash and fill material (FM). Samples were collected from the PLTU stockpile in the Tanjung Selor mining area, North Kalimantan, and compaction tests were conducted in the laboratory using the Standard Proctor method (ASTM D698). The results indicate that pure fly ash has a low MDD (0.94 t/m³) and high OMC (65%) due to its fine, lightweight, and porous particles. The addition of 35% fly ash to 65% fill material significantly increased MDD to 1.62 t/m³ and reduced OMC to 10%, demonstrating the interstitial filling effect that improves composite density. Fly ash is non-plastic with a specific gravity (Gs) of 3.02, enhancing the mechanical stability of the composite material without causing plastic deformation. The study concludes that a 35% fly ash proportion in the base course achieves an optimal balance between high density, low moisture content, and ease of compaction, while promoting sustainable mining infrastructure through industrial waste reduction and material cost efficiency.

Abstract

Earthquake-resistant buildings are structures designed to withstand lateral loads caused by earthquakes without damaging their structural elements. One effort that can be made is to use shear walls in medium-rise buildings. The purpose of this study is to study the behavior of the Aloon-Aloon Hotel multi-storey building located in Magelang City, which has medium soil characteristics with SDS of 0.61g and SD1 of 0.45g, risk category II. The scope of the study is a comparative study of buildings modeled with and without shear walls. Earthquake load planning refers to SNI 1726:2019 with the equivalent static analysis method. The process of modeling the building structure in this study uses three-dimensional structural analysis software based on the finite element method to study the behavior of the structure due to gravity loads and lateral loads. The results of the study are that buildings with shear walls have a higher building structure volume of 7.74% (shear walls, columns, beams) than buildings without shear walls (columns and beams). However, the use of shear walls produces lower deviation and capital values compared to buildings without shear walls, so that the building has high lateral stiffness in resisting lateral loads (designed earthquake loads). This shows that the use of shear walls significantly improves the strength and stiffness performance of structures in medium-rise buildings.

Abstract

This study evaluates the operational performance of Serdang Intersection, an unsignalized three-leg junction located in a commercial area connecting Serang–Cilegon Road and Waringinkurung Road. The assessment combines analytical procedures from the Indonesian Highway Capacity Manual 2023 and microsimulation modelling using PTV Vissim software. Analysis of current conditions shows a traffic flow of 3206 passenger car units per hour, a degree of saturation of 0.75, an average delay of 12.75 seconds per passenger car unit, and a queue probability ranging from 23 percent to 46 percent, corresponding to level of service B. Projections for 2033 indicate that traffic flow will increase to 4602 passenger car units per hour, the degree of saturation will exceed capacity at 1.08, average delay will rise to 23.80 seconds per passenger car unit, and queue probability will reach 47 percent to 94 percent, resulting in level of service D. These findings underscore the urgency of infrastructure interventions such as intersection geometry optimization, priority lane adjustments, and the installation of traffic signals to mitigate congestion risks. The study demonstrates the effectiveness of integrating the Indonesian Highway Capacity Manual 2023 with microsimulation modelling using PTV Vissim (Planning Transport Traffic-Traffic in Cities Simulation Model) in comprehensively forecasting traffic performance, and it offers strategic recommendations for urban planners and policymakers.

Abstract

Jalan Ahmad Yani is a vital economic and accessibility corridor in Sragen Regency that frequently experiences functional disruptions due to waterlogging. Therefore, the urgency of this research lies in the pressing need to mitigate the risk of structural degradation of the road pavement and prevent economic losses caused by persistent regional logistical obstacles. The flooding on Ahmad Yani Street in Sragen Regency is disrupting traffic and community activities. This study aims to analyze design rainfall intensity (10 and 20-year return periods) and evaluate the capacity of the existing drainage system using EPA SWMM 5.2 simulation. Rainfall intensity calculations were performed using the Gumbel and Mononobe methods, with an ATM distribution. Simulation results showed peak rainfall intensity reaching 82.70 mm (10 years) and 92.70 mm (20 years). Drainage capacity analysis indicates critical points. Junction node J4 (DTA 1) consistently experiences overflow of 0.941 m³/s, despite the large capacity of conduit C3, indicating a significant upstream flow contribution. Junction J14 (DTA 2 Segment 1) shows a large overflow of up to 1.973 m³/s, as the limited capacity of conduit C11 is unable to accommodate the accumulated flow. Junction J36 (DTA 2 Segment 2) also consistently overflows at 1.017 m³/s, indicating that the upstream flow accumulation exceeds its capacity despite the large capacity of conduit C39. It is concluded that the existing drainage system on Ahmad Yani Street is unable to adequately drain the volume of water during peak rainfall intensity, causing flooding. Recommendations include increasing channel capacity at critical points and a thorough evaluation of the drainage network. By identifying hydraulic system failures using dynamic simulation, this research makes a significant contribution by providing a precise map of critical points and a technical model that can serve as a database for relevant authorities, particularly the Sragen Regency Government, in formulating more adaptive and sustainable urban drainage infrastructure rehabilitation and development.

Abstract

Drainage problems along the Puloampel–Bojonegara Road in Serang Regency, Banten, have become a concern due to frequent waterlogging during the rainy season, where the dimensions or size of the drainage channels cannot accommodate the existing flow rate of 3,01 m³/sec, which causes water to overflow. In addition to impairing road user comfort, this flooding damages road infrastructure, raises the possibility of traffic accidents, and interferes with logistics distribution in the nearby industrial regions. This study aims to evaluate the performance of the existing drainage system and provide technical recommendations using HEC-RAS-based numerical modeling. The data used includes primary data from field surveys in the form of existing channel condition data, channel geometry data in the form of channel width and depth, channel slope, channel cross-sectional shape and secondary data such as rainfall data and land use data. Hydrological analysis was carried out using the Log Pearson Type III distribution to determine the design rainfall, while the discharge was calculated using the Manning equation. The results of the HEC-RAS simulation show that the existing channels have varying dimensions, where the width of the channel is 50 cm – 60 cm, and the height of the channel is 50 cm – 70 cm, which causes the drainage channel to be unable to accommodate flood discharge or flow discharge, with an average overflow height of 30 cm and a maximum of 61 cm. After geometric improvements were made to the channel by widening the channel to 100 cm and deepening the channel to 100 cm, re-simulation showed that all cross-sections were able to accommodate the flow, with an average water level of 35 cm below the edge of the channel. This study offers insightful technical information about the value of regular maintenance and the efficacy of drainage upgrades .
