Abstract

Water-induced deterioration remains one of the major causes of premature failure in Asphalt Concrete–Wearing Course (AC-WC) pavements, reducing pavement service life and increasing maintenance costs. This study investigates the effect of incorporating Unplasticized Polyvinyl Chloride (UPVC) waste as an additive on the durability of AC-WC mixtures subjected to different water immersion durations. Marshall testing was conducted following the 2018 Bina Marga General Specifications (Revision 2) using specimens immersed for 0.5, 1, 2, 4, 24, and 48 hours. The evaluated parameters included Marshall stability, flow, Marshall Quotient (MQ), Void in Mix (VIM), Void in Mineral Aggregate (VMA), Void Filled with Bitumen (VFB), and retained durability. The results indicate that the mixture containing 6% UPVC maintained satisfactory performance after prolonged immersion. Marshall stability remained above the minimum specification, decreasing from its optimum value to 1249 kg after 48 hours, while durability remained at 114.9%, exceeding the required 90%. However, the flow value gradually increased to 4.67 mm, indicating reduced resistance to permanent deformation under extended immersion. These findings demonstrate that incorporating 6% UPVC enhances the moisture resistance of AC-WC mixtures while supporting the sustainable utilization of plastic waste in pavement engineering.

Abstract

This study evaluates the bearing capacity of highway subgrade through laboratory California Bearing Ratio (CBR) testing under soaked and unsoaked conditions. The research aims to determine the physical characteristics, compaction properties, and bearing capacity of clayey sand subgrade collected from Sepi Highway, West Lombok, Indonesia. Laboratory tests were conducted in accordance with the relevant Indonesian National Standards (SNI), including soil classification, Standard Proctor compaction, and CBR testing. The soil was classified as clayey sand (SC) based on the Unified Soil Classification System (USCS) and as A-2-7 according to the AASHTO classification system. The maximum dry density and optimum moisture content were 1.390 g/cm³ and 27.782%, respectively. The unsoaked CBR value reached 6.674%, whereas the soaked CBR value decreased significantly to 3.115%, indicating a substantial reduction in bearing capacity under saturated conditions. These findings demonstrate that water saturation is the primary factor reducing subgrade performance. Therefore, chemical stabilization, soil replacement, geotextile reinforcement, and improved drainage are recommended to enhance pavement stability and prolong highway service life.

Abstract

The Way Merah 2 Bridge, located on the Gedong Aji Baru–Rawajitu road section in Lampung Province, has experienced structural deterioration and insufficient capacity, necessitating bridge replacement to ensure transportation safety and serviceability. This study aims to evaluate the geotechnical characteristics of the foundation soil, determine the axial bearing capacity of pile foundations, and assess the structural stability of the bridge abutment under various loading conditions. The research employed a quantitative analytical approach using field investigation data, including borehole, Standard Penetration Test (N-SPT), and cone penetration test results, combined with numerical modelling using MIDAS Civil software. Geotechnical analyses were conducted to determine soil classification, pile bearing capacity, deformation behaviour, and abutment stability against overturning and sliding under service, extreme, and seismic load combinations based on Indonesian bridge design standards. The results indicate that the study area is classified as Site Class SD (medium soil) with an average N-SPT value of 18.65. The allowable axial pile capacity of 839.20 kN exceeds the maximum applied axial load of 580.64 kN, indicating adequate foundation performance. Structural deformation remained within allowable limits, while most loading combinations satisfied the required safety factors, except one extreme overturning condition. These findings demonstrate that the proposed bridge replacement design is structurally and geotechnically feasible and provide practical guidance for improving bridge abutment performance under extreme loading conditions.

Abstract

Driver fatigue remains one of the leading factors contributing to road traffic accidents, particularly in long-distance freight transportation. Rest areas are provided as supporting facilities to reduce fatigue; however, their effectiveness depends largely on drivers' utilization behavior. This study aimed to analyze the behavior of freight transportation drivers in utilizing rest areas as a fatigue mitigation strategy at Rest Area KM 49A on the Bakauheni–Terbanggi Besar Toll Road, Lampung. A quantitative approach with a descriptive analytical design was employed. Data were collected through observations, questionnaires, interviews, and documentation involving 100 freight drivers selected using accidental sampling. The data were analyzed using validity and reliability tests, multiple linear regression, t-test, F-test, and coefficient of determination (R²). The results indicate that driver behavior and rest area utilization simultaneously have a significant effect on fatigue mitigation, while rest area utilization provides a greater contribution than driver behavior. Limited parking capacity and inadequate supporting facilities were identified as the main barriers to optimal utilization. The findings emphasize the importance of improving rest area facilities to enhance driver safety and reduce fatigue-related traffic accident risks.

Abstract

Employee dormitory buildings located in industrial areas require structural systems capable of resisting both gravity and seismic loads, particularly when constructed on soft soil that may amplify earthquake effects. This study aimed to evaluate the structural performance of a four-story reinforced concrete employee dormitory in Indramayu, Indonesia, under dead, live, and seismic loading in accordance with SNI 2847:2019 and SNI 1726:2019. A quantitative research design employing numerical simulation was adopted using ETABS software. Structural performance was assessed through the equivalent static seismic analysis by examining the natural period, base shear, inter-story drift, and reinforcement detailing of the reinforced concrete Special Moment Resisting Frame (SMRF). The analysis indicated that the calculated natural period satisfied the code requirements, the seismic base shear was appropriately distributed, and all inter-story drift values remained below the allowable limits. Furthermore, the column reinforcement detailing fulfilled the seismic ductility requirements specified in the Indonesian standards. These findings demonstrate that the proposed structural system provides adequate strength, stiffness, and stability for buildings constructed on soft soil. The study provides practical guidance for designing earthquake-resistant reinforced concrete buildings in soft-soil regions and contributes to improving structural safety in industrial residential facilities.

Abstract

The coastal area of Bedono Village, Demak Regency, Central Java, Indonesia, has experienced substantial land use changes due to the combined impacts of coastal abrasion, tidal flooding, land subsidence, and sea-level rise. Continuous monitoring of these environmental changes is essential to support sustainable coastal management and disaster mitigation. This study aims to analyze multitemporal land use changes between 2015 and 2025 by integrating the Normalized Difference Vegetation Index (NDVI), Normalized Difference Water Index (NDWI), and the Random Forest machine learning algorithm. Landsat 8 and Landsat 9 Level-2 Surface Reflectance imagery were processed using QGIS and the Semi-Automatic Classification Plugin (SCP). NDVI and NDWI were extracted as additional predictor variables to improve spectral separability before image classification. The results indicate a significant reduction in land area accompanied by extensive degradation of mangrove vegetation, particularly during the 2020–2025 period. The Random Forest classification demonstrates that integrating spectral indices substantially improves the identification of complex coastal land cover classes affected by mixed pixels. The resulting multitemporal land use maps provide reliable spatial information for evaluating coastal environmental changes and may support evidence-based decision-making for coastal disaster mitigation, climate change adaptation, and sustainable spatial planning in Demak Regency.

Abstract

Indonesia is located in one of the world's most seismically active regions, requiring high-rise buildings to be designed with adequate seismic resistance to control excessive lateral deformation and prevent structural instability caused by the P–Δ effect. This study evaluates the seismic performance of a multi-story building equipped with different Fluid Viscous Damper (FVD) configurations using Nonlinear Time History Analysis (NLTHA). Three structural models were investigated: a bare frame structure without dampers (Model A), a structure with uniformly distributed FVDs (Model B), and a structure with FVDs installed only at stories experiencing the largest inter-story drifts (Model C). Three scaled historical earthquake records—Imperial Valley, Loma Prieta, and Northridge—were employed according to the seismic requirements of SNI 1726:2019. The results demonstrate that Model A exceeded the allowable inter-story drift limits at several critical stories. Although Model B produced the greatest drift reduction, it significantly increased structural stiffness because of the extensive bracing system. In contrast, Model C effectively reduced inter-story drift to within the allowable limits while maintaining greater structural flexibility. These findings indicate that strategically placing FVDs at critical stories provides a more efficient seismic mitigation strategy than conventional uniform damper installation.

Abstract

Volcanic soil is characterized by high porosity and excellent water retention capacity, making its moisture characteristics highly sensitive to environmental conditions. This study aims to evaluate the effect of room temperature on the humidity and water content of volcanic soil and to examine the relationship between these parameters during laboratory storage. An experimental study was conducted using volcanic soil collected from Lagadar, West Bandung Regency, West Java, Indonesia. Relative humidity and room temperature were measured using an AS847 humidity meter, while water content was determined in accordance with ASTM D2216. The observations were performed over a 28-day period under uncontrolled laboratory environmental conditions. The results showed that relative humidity gradually decreased over time due to the natural drying process of the soil samples. An increase in room temperature was associated with reductions in both relative humidity and water content, indicating that evaporation played a significant role in moisture loss. Furthermore, relative humidity exhibited a strong positive correlation with water content, suggesting that humidity measurements can be used as an indicator of moisture changes in volcanic soils. These findings improve the understanding of the influence of environmental conditions on the moisture behavior of volcanic soils and provide useful information for laboratory material storage and future geotechnical applications.

Abstract

Bored piles are widely used as deep foundation systems to support heavily loaded structures, particularly in areas with soft surface soils. Accurate estimation of axial bearing capacity is essential to ensure foundation safety and structural performance. This study evaluates the axial bearing capacity of bored pile foundations using the empirical methods proposed by Reese and O'Neill (1989) and Meyerhof (1976), with verification through field testing. The analysis was conducted on bored piles with a diameter of 1000 mm and a working load of 450 tons in a multistory building project located in North Jakarta, Indonesia. Ultimate bearing capacities obtained from the empirical methods were compared with results from Static Loading Tests interpreted using the Mazurkiewicz method and Pile Driving Analyzer (PDA) Tests. Reese and O'Neill predicted ultimate capacities ranging from 1108 to 1116 tons, while Meyerhof produced values between 1132 and 1139 tons. Field verification yielded ultimate capacities of 845–905 tons from the Static Loading Tests and 1285–1350 tons from the PDA Tests. The Reese and O'Neill method provided estimates closer to the field-based static loading results than the Meyerhof method. These findings demonstrate the importance of field verification in evaluating empirical design methods and provide practical guidance for selecting appropriate approaches for bored pile foundation design under similar soil conditions.

Abstract

Construction projects frequently encounter challenges related to budget management, project delays, and resource procurement, all of which may significantly influence project performance. This study aims to analyze the direct and indirect relationships among these factors using an integrated Statistical Package for the Social Sciences (SPSS) and Partial Least Squares Structural Equation Modeling (SEM-PLS) approach. A quantitative research design was employed using questionnaire data collected from 150 construction professionals representing contractors, consultants, project managers, supervisors, and engineers. IBM SPSS 26.0 was utilized for descriptive statistics, validity, reliability, normality, multicollinearity, and multiple regression analyses, while SmartPLS 4 was used to evaluate the structural model. The results demonstrate that budget management has the strongest direct effect on construction project performance (β = 0.796, p < 0.001). Resource procurement exhibits the greatest influence on budget management (β = 0.834, p = 0.001), whereas project delays significantly affect both budget management and project performance. Furthermore, the proposed structural model satisfies the goodness-of-fit criteria (SRMR = 0.045; NFI = 0.945), indicating an acceptable model fit. These findings highlight the importance of effective financial planning and resource management in improving construction project performance and provide empirical evidence for project managers in developing strategies to minimize delays and optimize project outcomes.
