Abstract

The extensive use of concrete has accelerated the depletion of natural aggregates and increased the accumulation of underutilized agricultural waste. Durian peel is a biomass residue with potential application in cement-based materials. This study investigates the feasibility of using untreated durian peel fiber as an additive to coarse aggregate in K-175 grade concrete. Unlike previous studies that primarily focus on chemically treated natural fibers, this research establishes the baseline performance of untreated durian peel fiber to identify its practical limitations. An experimental program was conducted using fibers sourced from Serang and Cilegon, Indonesia, processed through cleaning, cutting, and drying. Concrete mixtures were prepared with fiber contents of 0%, 2%, and 4% by weight of coarse aggregate. Twelve 150 mm cube specimens were tested for slump and compressive strength at curing ages of 3 and 7 days. Results indicate that increasing fiber content consistently reduced workability and compressive strength. At 7 days, compressive strength decreased from 5.40 MPa to 4.10 MPa and 2.15 MPa for 2% and 4% fiber additions, respectively. These findings confirm that untreated durian peel fiber is unsuitable for structural concrete but may be suitable for non-structural applications after material modification.

Abstract

This study presents the structural analysis and seismic performance evaluation of an eight-story reinforced concrete apartment building in Kubu Raya Regency, Indonesia, designed using a Special Moment Resisting Frame (SMRF) system. The design follows the seismic and detailing requirements of SNI 1726:2019 and SNI 2847:2019. A three-dimensional finite element model was developed in ETABS, with beams and columns modeled as frame elements and slabs as shell elements, incorporating stiffness-reduction factors to represent cracked-section behavior. Structural analysis considered gravity, wind, and seismic loads in accordance with SNI 1727:2020 and SNI 1726:2019. Seismic performance was evaluated using response spectrum analysis, ensuring at least 90% modal mass participation in each principal direction. Performance checks included inter-story drift limits, earthquake force scaling, P-Delta effects, and horizontal and vertical irregularities. The results show that all seismic performance criteria are satisfied, with inter-story drifts within allowable limits and stable structural behavior. Reinforcement detailing for all structural components complies with SMRF requirements, ensuring adequate ductility. The foundation system using driven piles was verified based on site-specific SPT data. Overall, the structural system demonstrates sufficient strength, stiffness, and seismic reliability.

Abstract

Motorcycle accidents remain a serious road-safety problem in developing countries, particularly among young riders who often exhibit risky riding behaviors. Risk perception is considered an important factor influencing such behaviors and accident involvement; however, the relationships among these variables remain poorly understood. This study aims to examine the relationships among risk perception, risky riding behavior, and accident involvement among young motorcycle riders. A quantitative approach was employed, using primary data collected via structured questionnaires distributed to young motorcycle riders, yielding 368 valid responses. Data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM), including evaluation of the measurement and structural models. The results indicate that risk perception has a significant negative effect on traffic errors (p = 0.010), speeding violations (p = 0.025), traffic violations (p = 0.002), and safety violations (p = 0.002), but has no significant effect on control errors and dangerous actions. Furthermore, traffic errors, speeding violations, and control errors significantly increase the risk of accidents. These findings suggest that improving risk perception can reduce risky riding behavior and contribute to motorcycle accident prevention efforts.

Abstract

Urban construction activities often generate disturbances that affect surrounding traffic performance, particularly when projects are located near major road intersections. This study aims to identify and analyze construction-related risks associated with the Four Points Hotel development in Kubu Raya and evaluate their impact on traffic flow performance at the Gaforaya Roundabout along Ahmad Yani II Road. A quantitative approach was applied using primary data obtained from field surveys, including traffic volume and side-friction observations conducted in 2024. Multiple linear regression analysis was conducted in SPSS to examine the influence of several construction risk factors: project vehicle frequency, material loading and unloading activities, lane narrowing, working duration, and traffic management arrangements. The results indicate that traffic management is the most influential factor affecting traffic volume variation, accounting for 11.3% of the regression model. The highest observed traffic volume reached 1,960.6 passenger car units per hour during the weekend peak period. These findings highlight the importance of effective temporary traffic management strategies to minimize construction-related disruptions to urban traffic flow.

Abstract

Traffic accidents involving students in educational areas remain a significant road-safety concern, particularly in areas with high traffic and limited safety facilities. This study aims to analyse student travel patterns, identify school travel routes, assess the need for safety facilities, and develop a Safe Routes to School (SRTS/RASS) concept along the Jalan KH. Dewantara corridor in Solok, Indonesia. Primary data were collected through road inventory surveys, pedestrian observations, and student interviews. Student travel patterns were analysed using an Origin–Destination (OD) matrix. The results show that the highest number of student trips originates from Zone 12 in Tanah Garam Urban Village, with 462 trips. Motorcycles dominate student transportation modes, accounting for approximately 60% of trips. The analysis identified six pedestrian routes, two bicycle routes, and one public transport corridor. The study proposes several safety improvements, including School Safety Zones (ZoSS), pelican crossings, sidewalk upgrades, bicycle lanes, and improved traffic signs and road markings to support safer mobility within the educational area.

Abstract

Traffic accidents remain a critical challenge in urban transportation systems, particularly on arterial corridors with high traffic volumes. This study aims to evaluate traffic accident risk and identify accident-prone locations on Veteran Street and Pahlawan Street in Pontianak City, Indonesia. Traffic accident data from 2019 to 2023 were obtained from official records of the Pontianak City Police. Accident vulnerability was analyzed using the Accident Rate method to measure accident intensity per road length and the Equivalent Accident Number (EAN) method to incorporate accident severity through weighted casualty indicators. The Upper Control Limit (UCL/BKA) method was applied to determine statistical thresholds for identifying accident blackspots. Results show that both Veteran Street and Pahlawan Street have accident rate values exceeding 1.0, indicating that these corridors are categorized as accident-prone roads. Two segments were identified as significant blackspots: the 0.230–0.460 km segment on Veteran Street and the 0.000–0.175 km segment on Pahlawan Street, where EAN values exceed the BKA threshold. The findings highlight priority locations for traffic safety improvements and provide an empirical basis for infrastructure enhancements, traffic control measures, and enforcement strategies to reduce accident risk in urban road networks.

Abstract

Slope instability induced by rainfall infiltration and increasing pore-water pressure is a common geotechnical problem in tropical regions. This study evaluates the effectiveness of slope-reinforcement methods applied to the conduit channel slope at Cabean Dam, Central Java, Indonesia. Stability analysis was conducted using three limit-equilibrium methods—Ordinary, Bishop Simplified, and Morgenstern–Price—implemented in SLOPE/W. Three slope conditions were analyzed: the original slope configuration, slope flattening combined with soil nail reinforcement, and slope flattening combined with shotcrete treatment. A sensitivity analysis was performed by varying the pore pressure ratio (Ru) from 0.0 to 0.7 to represent different rainfall infiltration conditions. The results indicate that the initial slope condition is unstable, with safety factors below acceptable engineering standards. Soil nail reinforcement significantly improves slope stability but remains sensitive to increasing pore pressure. The combination of slope flattening and shotcrete treatment provides the highest safety factors and the lowest sensitivity to pore-pressure variations, indicating better performance for slope stabilization in high-rainfall environments.

Abstract

Flooding is a recurring hydrological problem in the Mendalam Sub-Watershed, Kapuas Hulu Regency, West Kalimantan, resulting in significant socioeconomic and environmental impacts. This study aims to (1) identify flood characteristics, (2) determine dominant hydrological and geomorphological factors contributing to flooding, and (3) evaluate flood discharge variations under different runoff coefficient scenarios. The analysis employs land-cover assessment, slope and soil-type evaluation, rainfall analysis, and factor analysis using the Kaiser–Meyer–Olkin Measure of Sampling Adequacy (KMO-MSA). Secondary data include rainfall records from 2004–2022, DEMNAS topographic data, and land-cover data from 2015, 2018, and 2022, whereas primary data were obtained through field observations and community interviews. Results indicate that slope is the dominant factor influencing flood occurrence, followed by rainfall, soil type, and land-cover change. The analysis also shows that increases in runoff coefficients lead to higher peak flood discharges, indicating the sensitivity of flooding to land-cover changes. These findings highlight the importance of integrated watershed management and land use control as key strategies for flood mitigation in the Mendalam Sub-Watershed.
