Abstract

Transportation is an important aspect in supporting the economy and helping community activities. To deal with the increasing mobility of the community, the DKI Jakarta provincial government in collaboration with PT Transportasi Jakarta has innovated to create a transportation program called Jaklingko. Currently, the Jaklingko microtrans already has 83 routes, one of which is the Jak 47 route which operates in the Ciganjur - Pasar Minggu area, South Jakarta. The service of route 47 seems to be unable to serve well which causes a buildup of users during peak hours so that the load factor increases. The purpose of this study is to analyze operational performance and analyze the existing performance of the Jak 47 microtrans. Data collection was carried out using a field survey method in the form of a dynamic survey and a static survey. Then the survey results will be compared with the 2002 Minimum Service Standards (SK Ditjen Hubdat No.687 / AJ.206 / DRJD / 2002). Based on the results of the analysis, operational performance indicators such as load factor, headway, travel time, speed and frequency have performed well.

Abstract

Depok City is an area that is experiencing changes in land cover due to very rapid regional development Apart from that, changes in land cover are also caused by population growth which continues to increase. This puts pressure on changes in land cover and its implications for land cover. Changes in land cover from vegetated land to built-up land will cause environmental problems, namely changes in land surface temperature. This research aims to identify land cover conditions based on the Normalized Difference Vegetation Index (NDVI), identify changes in land surface temperature, and analyze the effect of land cover changes based on NDVI on land surface temperature in Depok City in 2012-2022. This research uses spatial analysis to determine land cover changes based on the Normalized Difference Vegetation Index (NDVI) in Depok City 2012-2022. Satellite image data is interpreted to produce NDVI maps for 2 different years at a scale of 1:50,000. With changes in vegetated land cover, it causes changes in land surface temperature. To find out how big the relationship between these two things is, correlation analysis was carried out using linear regression analysis methods and spatial analysis methods. The results of this research are very significant changes in LST area from 2012 to 2022 with temperatures of <35°C in the Sawangan, Bojongsari, Tapos, Pancoran Mas and Limo sub-districts. Meanwhile, at a temperature of >40°C, very significant changes occur in the areas of Cimanggis, Cinere, Beji, Tapos and Sukmajaya sub-districts. The correlation between LST and NDVI in 2012 and 2022 has a strong negative correlation, which shows that the greater the NDVI value, the LST value tends to decrease.

Abstract

This study examines the implementation of a Work Breakdown Structure (WBS) in the preventive maintenance of the Total Fire System (TFS) to enhance building safety and reliability. Poor maintenance practices can compromise these aspects, increasing fire risks due to inadequately maintained fire protection systems. Utilizing WBS, the study breaks down maintenance tasks into manageable components, improving clarity and effectiveness in planning, execution, and documentation. The hierarchical WBS framework, validated through expert feedback via the Delphi method, was applied in a case study at the Faculty of Computer Science building at the University of Indonesia. The case study demonstrated significant improvements in operational efficiency and compliance with fire safety regulations. WBS enhances task clarity, allows effective scheduling of maintenance activities, and establishes a reliable documentation system. Key benefits of WBS include optimized resource use, cost savings, improved team collaboration, and extended lifespan of fire safety systems. To implement WBS effectively, the study recommends comprehensive training for maintenance teams, fostering collaboration among stakeholders, and adopting continuous improvement practices. In conclusion, this study illustrates that WBS significantly enhances TFS maintenance effectiveness and can be applied across various building types, promoting structured and efficient maintenance practices to improve safety and reliability.

Abstract

The construction sector in Indonesia faces a high risk of occupational accidents, particularly in irrigation network projects. This study develops a standardized Work Breakdown Structure (WBS) for irrigation projects to improve safety performance. The WBS standard, detailed into 177 activities across five levels, enables precise identification of safety risks during project planning. Utilizing expert validation through the Delphi Method, 708 risk variables were identified, with 25 dominant risks grouped into three main categories: heavy equipment-related accidents (material lifting failures and traffic collisions) and electric shocks. This framework enhances the implementation of preventive measures and aligns safety management systems with construction activities. Findings reveal that material lifting failures with mobile cranes, traffic-related heavy equipment accidents, and electric shocks are the most significant risks. Integrating WBS-based safety planning during pre-construction improves project safety performance, reduces costs, and enhances sustainability. This research highlights the critical need for comprehensive safety strategies tailored to irrigation projects.

Abstract

To facilitate downstreaming in mining industry, the law requires holders of Mining Business Permits (IUP) and Work Contracts (KK) to establish smelters, namely mining processing facilities that function to increase metal content to a level that meets standards as raw materials for final products. From the policy factors found that policy has a role in the problem of delays in smelter construction in Indonesia. Therefore, evaluation and improvement of regulations as a solution to the problem need to be carried out so that smelter construction as an effort to implement mining downstreaming can be implemented properly. The study was conducted by collecting qualitative primary data which was analyzed using Structural Equation Modeling (SEM). In the relationship between policy variables and project time performance variables, Variable X3 Supervision and Variable X6 Force Majeure has a significant effect on the project time performance variable, while other variables do not have a significant effect.

Abstract

Castellated steel is a steel beam that has a hexagonal hollow web element. One of the cases that often occurs in castellated steel structures is buckling. This study takes a case study of ramp door construction made of castellated steel. The ramp door construction experienced buckling damage after a load test. Analysis was carried out on four ramp door models with loading resembling the actual conditions of the bridge according to SNI 1725-2016. The first modeling uses a 900x200x11x17 castellated main beam without the addition of stiffeners. The second modeling with the addition of stiffeners at each distance between castellated holes. The third modeling closes all holes without the addition of stiffeners. The fourth modeling closes all holes with the addition of stiffeners at each distance between castellated holes. The analysis was carried out using the finite element method. This study aims to determine the effect of stiffeners and castellated hole covers on deformation values, equivalent stress and buckling eigenvalues. From the analysis of the effect of stiffener (second model) for the deflection value decreased by 0.62%, the stress value increased by 4.04%, the buckling eigenvalue increased by 144.94%. The effect of castellated cover (third model) for the deflection value decreased by 8.69%, the stress value decreased by 19.71%, the buckling eigenvalue increased by 12.75%. The effect of stiffener and castellated cover (fourth model) for the deflection value decreased by 11.18%, the stress value decreased by 20.15%, the buckling eigenvalue increased by 153.98%.

Abstract

This study examines the effectiveness of the Construction Safety Management System (CSMS) implementation in the field according to the plan and analyzes the main factors influencing the application of CSMS in high-rise construction projects in Banjarmasin. The research methods involved interviews, questionnaires, and Relative Importance Index analysis. The results show that the administrative aspects of SMKK implementation comply with applicable regulations, and its field implementation runs well and appropriately. The potential for occupational accidents has been minimized through various important measures taken by contractors, such as the availability of Standard Operating Procedures (SOP) for work, socialization and promotion of occupational safety and health, conducting Toolbox Meetings, Safety Induction, Safety Morning Talks, provision of Personal Protective Equipment (PPE), procurement of Fire Protection Equipment, and installation of OSH informational signs. Additionally, checklists were conducted on work locations, work equipment, permits, scaffold use and training, worker health, and labor insurance. Routine evaluations of CSMS implementation were also carried out. Proper and effective “CSMS” supervision also played a role in reducing the risk of occupational accidents and ensuring no delays in project completion. All these actions reflect a commitment to worker safety and health and make “CSMS supervision an integral part of the smooth operation of construction projects. Significant factors influencing the potential for occupational accidents include inadequate work execution methods and workers’ understanding of operating work equipment. Meanwhile, well-implemented accident control factors include the availability of work methods and operational programs, as well as regular inspection and maintenance of equipment. In terms of supervision, the use of PPE by workers and supervision of accident risks have also proven to be very effective. These findings emphasize the importance of comprehensive safety management and continuous supervision in construction projects.

Abstract

This study examines the effects of seawater salinity on the mechanical and permeability properties of concrete made with Portland Composite Cement (PCC), a sustainable alternative to Ordinary Portland Cement (OPC) with up to 30% lower CO₂ emissions. Concrete specimens were cured in water ponds with salinity levels of <0.1%, 0.2–0.4%, 0.6–0.7%, and 3–3.5% to simulate coastal exposure. Compressive strength, splitting tensile strength, permeability, and Ultrasonic Pulse Velocity (UPV) were tested at 7, 28, 42, 56, and 90 days. Compressive strength generally increased with age, but the target of 41.4 MPa was not consistently reached by 42 days. High salinity exposure reduced tensile strength and produced more brittle fracture patterns, indicating increased cracking potential. Interestingly, permeability decreased in high-salinity samples, possibly due to salt crystallization within pores, though this was not supported by UPV results. The weak correlation between UPV and both strength and permeability suggest microstructural effects not captured by non-destructive testing alone. PCC concrete showed acceptable performance in low-salinity conditions (<1%), making it suitable for mildly aggressive marine environments. These findings support the broader use of PCC in sustainable construction and highlight the need for further microstructural investigation under saline exposure.

Abstract

The assessment of reinforced concrete (RC) building structures is a critical step in ensuring the sustainability and functional reliability of existing facilities. This study aims to evaluate the quality of concrete using Non-Destructive Testing (NDT) methods—namely Rebar Locator, Rebound Hammer (RH), and Ultrasonic Pulse Velocity (UPV)—and to formulate maintenance strategies based on concrete quality classification. Testing was conducted on six column locations of a three-story office building, with measured compressive strength values ranging from 36.3 MPa to 48.9 MPa and ultrasonic pulse velocities ranging from 2.57 m/s to 4.75 m/s. The test results were interpreted to determine the condition levels of the concrete, which subsequently served as the basis for recommending appropriate maintenance actions. The findings revealed that structural elements at Level 1 were classified as Excellent, whereas Levels 2 and 3 exhibited conditions ranging from Good to Doubtful. Maintenance strategies were formulated accordingly, encompassing routine maintenance, localized repair, and structural strengthening in critical areas. This NDT-based approach enhances the accuracy of condition-based maintenance planning and contributes to both the sustainability and safety of reinforced concrete building structures.

Abstract

One of the Trans-Sulawesi road sections that frequently happen traffic accidents is the Kolaka – North Kolaka road section. The protected forest area on the Tamborasi Incline (KM 78 – KM 81) in Iwomenda District, Kolaka Regency is the highest accident-prone area with a total of 87 accidents since 2022. The causal factors are poor road conditions, damaged road equipment, lack of lighting, and driver negligence. The solution to address this problem is by conducting a comprehensive audit on the Kolaka – North Kolaka road section. The purpose of this study is to provide academic studies for the local government in implementing the management of traffic accident-prone areas through road safety audits to reduce the accident rate towards Zero Accident. The method used is the road safety audit method including field surveys, identification of accident-prone points (black spots), road geometric analysis, and evaluation of supporting safety facilities such as signs, markings, and street lighting. The audit results showed that several road segments have significant deficiencies in geometric aspects and the completeness of safety facilities, which directly contribute to the high risk of accidents. The percentage of factors causing accidents are human factors (56.42%), vehicle factors (10%), physical environmental conditions (21.42%), and road conditions (12.14%). Recommendations for improvement are provided based on the audit findings for implementation by relevant parties, such as improving infrastructure quality, adding warning signs, and regulating vehicles. It is hoped that the results of this study can inform policymaking in planning and improving the road transportation system to create a safe and comfortable traffic environment without accidents, aiming for a Zero Accident target in the Kolaka-North Kolaka area.
