Abstract

In the design of steel truss bridges, selecting the appropriate truss configuration and height is a critical step that significantly impacts the overall structural performance. Steel truss bridges feature various configurations with distinct structural characteristics related to span length, structural weight, and deflection. Deflection serves as a key parameter to assess structural stiffness, while structural weight greatly influences the economic feasibility of the bridge design. Achieving weight efficiency without compromising structural performance can effectively reduce construction costs, resulting in a strong and economical bridge. Based on a review of multiple studies, it is evident that both truss configuration and height strongly affect deflection and total structural weight. Among Indonesia's four common truss types"”Warren, Pratt, Howe, and K-Truss"”the Howe configuration exhibits the least deflection, indicating superior stiffness. Additionally, increased truss height inversely correlates with axial forces and deflection; higher trusses experience lower axial forces in the members and reduced deflections. Furthermore, the choice and dimensioning of truss member profiles substantially influence the resulting structural weight. Therefore, an integrated approach to optimising truss configuration, height, and member sizing is essential for developing steel truss bridges that balance structural efficiency, strength, and cost-effectiveness.

Abstract

Infrastructure development in Pontianak, particularly the Kapuas Bridge Duplication Project 1 (MYC) 2022-2024, requires thorough foundation planning due to the area"™s soft, water-saturated soil with low bearing capacity. This study analyzes the ultimate bearing capacity (Qu) and settlement of 80 cm diameter steel pile foundations at pile point 3. The analysis reveals that the minimum pile bearing capacity (Qall) using the Brown (2001) method is 274,25 tons, while the APILE v.2019 program yields a bearing capacity of 383,3 tons. The group pile-bearing capacity analysis shows a total capacity of 2.875,511 tons, exceeding the applied working load of 2.683,304 tons, with a group efficiency of 0,699. The elastic settlement for a single pile is 3,87 mm, while the pile group"™s is 13,95 mm. Long-term consolidation settlement is calculated at 126,20 mm, while PLAXIS simulation results show 72,03 mm. Interpreting static load test results using various methods (Chin, Davisson, Meyerhof, etc.) shows variation in bearing capacity, with the Meyerhof method providing the most consistent results. Based on this analysis, the 80 cm diameter steel pile foundation meets the safety and stability requirements for long-term use.

Abstract

Understanding wave propagation, particularly in shallow water where nonlinear and dispersive effects become prominent, is essential for achieving accurate hydraulic modeling. HEC-RAS is a widely utilized computational tool in engineering applications for simulating open channel flows, predominantly under the assumption of hydrostatic pressure. This study investigates the capability of HEC-RAS to simulate wave propagation under conditions characterized by strong nonlinearity and dispersion. To conduct this evaluation, three benchmark scenarios were modeled: (1) solitary wave propagation in a flat, frictionless channel, (2) interaction of a solitary wave with a submerged bar, based on experimental data, and (3) regular wave propagation. Each case was simulated using HEC-RAS and the results were compared against analytical solutions or experimental observations. The findings indicate that HEC-RAS exhibits notable limitations in accurately representing wave phenomena dominated by nonlinear and dispersive effects. These limitations are primarily attributed to the shallow water equations implemented in the model, which omit non-hydrostatic pressure components. Such components are critical for maintaining wave shape and amplitude, particularly over variable bathymetry. In conclusion, while HEC-RAS remains a robust and reliable tool for conventional flow modeling, it is not well-suited for scenarios involving strongly nonlinear and dispersive wave propagation. For such cases, alternative modeling approaches that incorporate non-hydrostatic pressure effects are recommended to ensure greater simulation accuracy.

Abstract

This study examines the use of glass powder as a filler substitute in Hot Rolled Sheet"“Wearing Course (HRS-WC) asphalt mixtures to enhance performance and promote waste utilization. The research employed an experimental method following SNI and AASHTO standards, testing mixtures with 0%, 25%, 50%, 75%, and 100% glass powder substitution using the Marshall method. Results showed that 50% and 75% substitution levels produced the best performance in terms of stability and Marshall Quotient, while 100% substitution led to a decline due to the glass powder"™s inability to absorb asphalt. Increased glass powder content also reduced VIM values, indicating denser mixtures, although at 100% substitution, both VIM and VMA exceeded specification limits. The findings suggest that glass powder can be effectively used as a partial filler replacement, with optimal results achieved at 50"“75% substitution and 5"“7% asphalt content.

Abstract

This study investigates the effect of the number of compaction impacts on the void characteristics of Asphalt Concrete-Wearing Course (AC-WC) mixtures with cement as an additive filler. The research employed an experimental approach, testing mixtures with two filler types: stone dust alone and a combination of stone dust with 1% cement. Compaction levels varied at 2×65, 2×75, and 2×85 blows, and Marshall tests were conducted to evaluate stability, flow, Voids in Mix (VIM), Voids in Mineral Aggregate (VMA), and Voids Filled with Bitumen (VFB). Results demonstrated that increasing compaction effort and adding 1% cement reduced VIM and VMA while enhancing stability and VFB. The lowest VIM (2.53%) and highest stability (1078.45 kg) were achieved with 6.5% asphalt, 1% cement, and 2×85 blows, indicating improved mixture density and load resistance. The findings align with Bina Marga 2018 specifications, highlighting the benefits of cement as a filler and optimal compaction for AC-WC performance.

Abstract

The Melawi watershed is increasingly burdened by environmental pressures stemming from rapid population growth and significant land-use transformations, which have intensified soil erosion processes. This study was undertaken to (a) estimate erosion rates and delineate erosion hazard levels through the application of the Universal Soil Loss Equation (USLE) model integrated with Geographic Information System (GIS) tools, (b) identify the principal factors contributing to erosion, and (c) assess the applicability of conservation measures aimed at erosion mitigation. The research involved field surveys, laboratory analyses, and geospatial data processing to quantify the USLE parameters: rainfall erosivity (R), soil erodibility (K), slope length and steepness (LS), land cover (C), and conservation practices (P). Results indicate an average erosion rate of 275,099.17 tons per hectare per year, with moderate erosion hazard levels encompassing approximately 41% of the total study area. Despite these findings, a comprehensive evaluation of conservation strategies was constrained by the predominance of moderate erosion levels. Nevertheless, the outcomes of this study provide critical insights to inform regional land use policy and the development of targeted soil conservation initiatives.

Abstract

This study examines the traffic performance and Level of Service Index (LSI) of Jalan Khatulistiwa in Pontianak City, utilizing the Indonesian Road Capacity Guidelines (PKJI) 2023. The analysis incorporates primary data collected through traffic volume counts, side friction observations, and travel time surveys over three days, representing weekday and weekend conditions. Traffic volume is converted into passenger car units (PCU) using equivalency factors, and side friction is quantified based on the weighted occurrences of pedestrian activities, stopped vehicles, and vehicle entries and exits. The calculated road capacity under existing geometric and environmental conditions is 3026.8 PCU/hour, with a free flow speed of 40.641 km/h. The degree of saturation during peak hours reached 0.603, corresponding to Level of Service D, characterized by near-unstable traffic flow. Regression analysis demonstrated a strong relationship between travel time and traffic flow, with determination coefficients ranging from 0.7704 to 0.8964. The Level of Service Index (LSI) was further evaluated using both linear and nonlinear methods, producing consistent results. This research provides a technical basis for evaluating traffic performance, enabling engineers and planners to optimize traffic operations and inform future road network designs in urban environments.

Abstract

The relocation of Indonesia"™s capital to Nusantara (IKN) represents a transformational initiative to establish an innovative, sustainable, and inclusive government center in East Kalimantan. Under a Public-Private Partnership (PPP) model, IKN is envisioned as a carbon-neutral city with resilient infrastructure and technology-based public services. Despite 97,2% completion of the first development phase by early 2025, the project faces significant challenges, including heavy reliance on state funding (85%), limited private sector participation (10%), underdeveloped logistics, and a shortage of skilled labor in technologies such as Building Information Modeling (BIM), Internet of Things (IoT), and modular construction. This study employs a qualitative exploratory approach using secondary data, integrating SWOT analysis, international benchmarking (Brasília, Naypyidaw, Putrajaya), and technological evaluation. Findings indicate that digital construction technologies can improve project efficiency by up to 30% and reduce material waste by 25%. Alternative financing strategies, including green bonds and Islamic crowdfunding, can potentially increase private investment up to 40% by 2030. For long-term success, IKN must adopt innovative construction practices, invest in digital workforce development, and align with Net-Zero 2045 and the SDGs. This study contributes a comprehensive policy-technology-investment roadmap for sustainable capital development in emerging economies.
