Abstract

This study presents a technical overview of a coastal road embankment constructed in a tidal zone of a small island in Indonesia. The objective is to document the integrated application of non-woven geotextile and multi-level gabions as a stabilization system on moderately strong subgrade soils affected by tidal dynamics. The research method involved descriptive analysis based on as-built documentation and field data, including California Bearing Ratio (CBR) tests at three locations. The results showed CBR values ranging from 41.11% to 60.84%, which classify the subgrade as moderately strong. Despite this, the use of geotextile was essential to prevent mixing of soft subgrade and fill material, provide load distribution, and ensure drainage, while the gabion structures acted as lateral confinement and toe protection against erosion caused by tidal infiltration. The findings suggest that soil strength alone is insufficient for coastal infrastructure design, and integrated stabilization measures should account for environmental forces such as saturation cycles and hydraulic pressure. This case offers a practical insight into adaptive geotechnical strategies for road construction in tidal zones, serving as a reference for similar projects in archipelagic and low-lying coastal regions.

Abstract

Achieving sustainability in construction projects requires active involvement from all stakeholders in implementing environmentally responsible techniques and materials throughout the project lifecycle. This study aims to identify and analyze the barriers to sustainable construction implementation from the perspectives of both state-owned and private contractors. A purposive sampling technique was employed to determine the study participants. Using the Interpretive Structural Modeling (ISM) approach, this research reveals key hierarchical barriers within each contractor group. For state-owned contractors, the most prominent barriers include A1 (Lack of knowledge and standards), A5 (Project manager incompetence), and A6 (Limited access to sustainable materials and technology). In contrast, private contractors identified A1 (Lack of knowledge and standards), A2 (Poor design practices), and A4 (Lack of communication between project stakeholders) as the most critical barriers. These findings suggest that different strategies and policy interventions are needed to address context-specific barriers in order to accelerate the adoption of sustainable construction practices across sectors.

Abstract

Rapid land use change in the Jalan Raya Gringging area necessitates a thorough analysis of the drainage system capacity to forecast increased flooding, especially during the rainy season. A mix of descriptive and quantitative methods was employed, including field surveys to measure the physical size and condition of the drainage channels, and hydrological and hydraulic analyses to assess system performance. Hydrological analysis used rainfall data from the past ten years to estimate peak discharge via rational method calculations. The hydraulic analysis evaluated the channel's ability to efficiently convey floodwaters. The results showed that the existing drainage capacity was able to accommodate the flow discharge according to the design discharge with various return periods. However, inundation conditions that occur during the rainy season are caused by elevation differences between the channel and the road surface, so as an effort to increase the efficiency of the drainage system and reduce the risk of inundation, it's recommended that the application of infiltration wells as a complementary strategy that serves to reduce the volume of surface inundation and can strengthen the effectiveness of the existing drainage system. This research expected to contribute to the development of SuDS-based adaptive drainage system planning.

Abstract

Suburban areas with predominantly residential land use and low soil infiltration rates are highly vulnerable to surface runoff and local flooding. This study examines the effectiveness and economic performance of bioretention systems as a runoff management solution in the Wonojati and Jenggawah areas, Jember Regency. Hydrological simulations were conducted using SWMM 5.2 software for two intervention scenarios, namely the application of bioretention in 10% and 20% of the subcatchment areas. The effectiveness of the system was evaluated based on runoff volume reduction, while the economic aspect was assessed using the Benefit-Cost Ratio (BCR) approach. The simulation results showed that the system reduced runoff by 13.6% in Plan 1 and 17.4% in Plan 2. However, BCR values of 0.014 and 0.022, respectively, indicate that the annual financial benefits are not sufficient to cover the system’s annualized costs. These findings highlight the need for alternative approaches that are more economically efficient. The use of decentralized LID systems such as rain barrels is considered more adaptive for dense residential areas and is recommended as a complementary solution to enhance the resilience of drainage systems in flood-prone suburban regions.

Abstract

Construction activities inherently carry risks that can lead to accidents, causing delays, injuries, and financial losses. In high-risk projects such as High Voltage Direct Current (HVDC) transmission tower construction, inadequate safety practices and low awareness of Occupational Health and Safety (OHS) increase the potential for workplace accidents. This qualitative descriptive study analyzes potential work hazards in HVDC tower construction using secondary data and the Job Safety Analysis (JSA) method. Four main work processes—tower leg, body, and cross arm installation, and cable pulling—were assessed. Results show that all activities involve significant risks, with falls from height, falling objects, and puncture/scratch injuries being the most common. There are 6 activities in the Extreme category, 3 activities in the High category, 14 activities in the Moderate category, and 8 activities in the Low category. The main risks are falling from heights, being struck by materials, and injuries caused by work tools, which are exacerbated by low use of PPE, weak supervision, and lack of worker compliance. The solution to this problem lies in control priority, where there are four solutions: elimination, engineering, administration, and personal protective equipment control.

Abstract

Road construction projects are among the sectors with a high risk of work-related accidents. One of the main causes is the low awareness and compliance of workers in using Personal Protective Equipment (PPE), which should be an integral part of Occupational Safety and Health (OSH) implementation. This study aims to evaluate the implementation of OSH, particularly regarding the use of PPE, in a road improvement project in Kabanjahe District, Karo Regency. The method used is a quantitative approach through questionnaires distributed to 140 field workers. The analysis results show that factors such as lack of education on PPE, weak supervision by management, substandard PPE quality, and a work culture that neglects safety are the main reasons for low compliance. The most influential factors include lack of awareness of work safety importance and absence of routine training related to OSH. Therefore, an integrated strategy is needed, which includes intensive education, provision of PPE that meets national standards (SNI), as well as strict supervision and enforcement, to ensure optimal OSH implementation and reduce the number of work accidents in construction projects.

Abstract

Denpasar City has experienced many changes in the use of public transportation. In the previous year 18 active routes operating, while currently there are only 5 active routes. Therefore, an analysis of the performance of transportation, route network plans, and operational systems of the transportation is needed. Primary data was obtained from headway surveys, interview surveys, and on-board surveys. Vehicle Operating Cost (VOC) calculations, route network planning, and operational systems used the Department of Transportation method. The results of the analysis showed that almost all routes did not meet the standards of both operational performance and service quality. In this study, 6 routes were planned centered on the east parking lot of Renon field. The results of the new route planning are: Renon-Penatih with a route length of 18.7 km, a circulation time of 61.5 minutes and a total of 13 vehicles; Renon-Ubung with a route length of 22 km, a circulation time of 69.8 minutes and a total of 46 vehicles; Renon-Sanur with a route length of 14.3 km, a circulation time of 45.6 minutes and a total of 3 vehicles.
