Abstract

Box culverts are critical infrastructural elements routinely subjected to complex soil-structure interaction phenomena. The conventional approach of assuming rigid foundation supports often leads to an unrealistic distribution of internal forces, potentially resulting in overly conservative or dangerously unconservative designs. This study investigates the structural behavior of a reinforced concrete box culvert by comparing a fully rigid support model against subgrade reaction models utilizing spring placements. Specifically, the analysis evaluates the variations in maximum bending moment (Mmax), axial force (Pmax), maximum shear force (Vmax), and deflection (Δ) across the top slab, vertical walls, and bottom slab. The spring models are further dissected into three configurations: springs without rigid links, springs with 4 rigid links, and springs with 8 rigid links. The findings reveal that the transition from rigid to spring supports fundamentally alters the load distribution, significantly reducing bottom slab axial forces from 135.94 kN to 0.00 kN in extreme cases, while modifying shear and moment profiles across the structure. The inclusion of rigid links demonstrates a stabilizing effect, closely mimicking realistic soil restraint while preventing localized stress concentrations. This research provides critical insights for engineers seeking to optimize box culvert designs by accurately modeling subgrade reaction.

Abstract

Temporary market activities along urban corridors may generate roadside friction that directly affects traffic performance. This study aims to analyze the impact of temporary market activity around the Bima Sports Complex in Cirebon City on road segment performance using a microsimulation approach. The model was developed in VISSIM based on field data, including road geometry, traffic volume, vehicle composition, speed, and roadside activity characteristics under two conditions: weekday or normal condition and weekend condition when temporary market activity takes place. Model validation was conducted using the GEH statistic by comparing simulated and observed traffic volumes. The validation results showed GEH values ranging from 0.214 to 1.138, indicating that the model was acceptable for comparative performance analysis. The results showed that total traffic volume increased from 3,148 vehicles/hour under normal conditions to 5,557 vehicles/hour on Sunday. This increase was accompanied by the use of roadside space for parking, temporary stopping, trading activities, and pedestrian movements. The average two-direction speed decreased from 27.91 km/h to 5.05 km/h, while the average delay increased from 1.65 seconds/vehicle to 94.48 seconds/vehicle. The level of service also declined from LOS A to LOS F. These findings indicate that road performance degradation was not only caused by increased traffic volume, but also by intensified roadside friction and reduced effective roadway width. The results provide an initial basis for developing temporary traffic management strategies for urban corridors affected by periodic market activities.

Abstract

Transportation is vital for community mobility, particularly in remote areas like Kilang Village in Ambon City, which relies heavily on Route 47 city services. This route serves a strategic purpose by linking the community to the city's main activity center, which includes the Mardika Terminal as the primary transit hub. This study seeks to assess service quality levels, identify gaps between passenger expectations and actual experiences, and pinpoint priority areas for improvement on the Kilang Route 47 City Transportation by evaluating perceptions across the dimensions of physical evidence, empathy, responsiveness, reliability, and assurance. Data were collected from 100 respondents using 24 indicators through the distribution of questionnaires. The study's findings indicate that the overall service quality scores 72. 78, which is categorized as good. However, a substantial discrepancy was identified between expectations and reality, especially regarding terminal and bus stop cleanliness, service speed, accessibility, and the availability of route information. Consequently, enhancing these areas should be a top priority to improve service quality and user satisfaction, particularly in regions heavily reliant on public transit.

Abstract

Ketapang Regency is widely known for its ale-ale clam (Meretrix sp.) commodity, yet high consumption rates generate a massive amount of hard shell waste that remains underutilized and pollutes the environment. Concurrently, conventional paving block production continuously exploits natural fine aggregates on a massive scale. This experimental study aims to analyze the effect of utilizing ale-ale shell waste as a partial substitution for fine aggregate on the compressive strength and water absorption characteristics of paving blocks based on the SNI 03-0691-1996 standard. The reference mixture proportion used was 1 Cement : 4 Sand (by volume) with variation rates of ale-ale shell substitution at 0% (normal), 5% (Variation I), 10% (Variation II), and 15% (Variation III). A total of 48 samples were tested to evaluate the compressive strength at 7, 14, and 28 days, as well as water absorption at 28 days. The results indicated that the optimum compressive strength growth was achieved by Variation II (10% ale-ale shell), reaching 17.23 MPa at 28 days, which significantly increased compared to the normal sample at only 14.06 MPa. Conversely, increasing the shell content to 15% in Variation III drastically reduced the compressive strength to 10.78 MPa. In terms of physical testing, Variation II (10%) recorded the lowest and most dense water absorption percentage of 9.83%. The water absorption characteristics of other variations exceeded the threshold, measuring at 10.32% (normal), 10.75% (Variation I), and 11.26% (Variation III). Based on the SNI 03-0691-1996 specification, only Variation II (10%) was declared to satisfy all physical and mechanical feasibility parameters for Grade D paving block classification (non-structural/garden).

Abstract

Soft soil is a major challenge in construction projects due to it’s low bearing capacity and it’s tendency to undergo settlement under loading, especially with high embankments. One of the consequences of this condition is the development of negative skin friction on pile foundations, which can significantly reduce their bearing capacity. This study aims to analyze the influence of embankment height on the magnitude of negative skin friction based on Cone Penetration Test (CPT) data and to evaluate it’s impact on pile foundation stability. The primary data was obtained from CPT results at point S – 6, which include soil parameters such as qc, fs, and soil classification. The calculation results show that negative skin friction increases with higher embankment levels, with the highest value observed at a 3.5 meter embankment height, however the increase is not linear. Despite the additional load caused by negative skin friction, both group and single pile foundations still meet the safety criteria. In addition, the elastic settlement remains below the allowable limit. Based on these findings, it can be concluded that while negative skin friction must be considered in foundation design, the pile foundations at the study site remain safe against the effects of high embankments.

Abstract

This study aims to analyze the effect of a combination of Palm Kernel Shell Ash (PKSA) and Styrene-Butadiene Rubber (SBR) Latex on the compressive strength of concrete and to determine the composition that provides optimal performance. PKSA was used as a partial substitute in the concrete mix, while SBR Latex was used as a polymer material at various concentrations. Compressive strength testing was conducted on concrete specimens at 28 days of age to determine the effect of composition variations on concrete strength. The results showed that the B-M5 mixture, with a 5% PKSA substitution and no SBR latex, yielded an average compressive strength of 14.95 MPa, whereas adding 1% SBR latex to the B-M5P1 mixture increased the compressive strength to 18.56 MPa—a 24.15% increase. However, increasing the SBR Latex content to 2% did not result in an increase in compressive strength and actually caused a decrease in strength. Among all the modified concrete variations, the combination of 5% PKSA and 1% SBR Latex produced the highest compressive strength at 28 days. The results of the study indicate that the combination of PKSA and SBR Latex can affect the compressive strength of concrete, with the effectiveness depending on the proportions of the materials used. The combination of 5% PKSA and 1% SBR latex was the most effective composition based on the compressive strength test results in this study.
