Abstract

The construction industry, recognized as one of the most hazardous sectors globally, continues to face escalating challenges, particularly in Indonesia. This sector experiences a yearly increase in workplace accidents, which significantly disrupts economic stability at both micro and macro levels. These incidents lead to substantial economic losses, reduced productivity, and increased medical and compensation costs. To address these risks, the adoption of Learning from Incidents (LFI) has emerged as a critical approach. LFI is a structured process that involves analysing and learning from past incidents to prevent future occurrences, offering a proven methodology to enhance workplace safety. However, despite its potential, the implementation of LFI in Indonesia encounters persistent obstacles. These include a weak safety culture, inadequate reporting systems, and insufficient enforcement of safety standards. Such challenges hinder the effectiveness of LFI and limit its capacity to drive meaningful improvements in construction safety. This study seeks to bridge the gap between the importance and current performance of LFI implementation in the Indonesian construction industry. The research methodology integrates a literature review, expert validation, and Importance-Performance Analysis. Through the literature review and expert validation, critical indicators for LFI implementation were identified, while the Importance-Performance Analysis assessed the alignment of expectations with actual performance as perceived by construction practitioners. Input from three construction safety experts and industry practitioners formed the basis of the analysis. The findings reveal that while Investigation Participation met or exceeded expectations, several other LFI implementation indicators–including Contextual Safety Engineering and Dissemination Reach–require substantial improvement. This consensus highlights significant discrepancies between intended outcomes and actual practices, underscoring the need for targeted strategies to enhance LFI processes. Addressing these gaps can better align LFI implementation with safety objectives, ultimately fostering a safer and more sustainable construction industry in Indonesia.

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

The implementation of the Construction Safety Management System (SMKK) generally focuses on contractors because accidents often occur during construction work. However, construction safety is a shared responsibility among all parties involved in construction projects. This study aims to identify the safety maturity level of clients in the implementation of SMKK and to develop strategies to improve client safety maturity so that SMKK implementation can be enhanced. The measurement of client safety maturity used criteria based on the audit form attached to Permen PUPR No. 10 of 2021 concerning SMKK, which was validated by experts through two rounds of the Delphi method. Respondent samples were selected based on specific criteria using purposive sampling to obtain respondents who served as Budget User Representatives, Commitment-Making Officials, and Procurement Working Groups in the procurement of construction goods and services. Expert validation was used to assess the suitability of conditions and formulate strategies. The results of the study showed that the maturity level of clients was between reactive and compliant. Internal audits and management reviews by clients in the implementation of SMKK were generally conducted only when accidents occurred. To improve SMKK implementation, clients need to establish clear procedures as references for conducting audits and management reviews.

Abstract

The high frequency of traffic accidents in the land transportation sector, especially those involving intercity and interprovincial buses (AKAP), indicates that the safety aspect of passenger transportation is still a significant problem. This study aims to analyze the factors that contribute to the risk of accidents for AKAP bus drivers at the Jatijajar Type a Terminal, Depok. A quantitative approach is used with the Structural Equation Modeling (SEM) method to test the multidimensional relationship between driving behavior, drivers' mental and physical condition, company management, government regulations, environment and traffic, and vehicle factors to accident risk. The SEM-PLS analysis revealed that five factors significantly influenced the accident, collectively explaining 59.8% of the total variance in AKAP bus accidents. Mental and Physical Condition factors were the strongest predictors (coefficient = 0.302), followed by Risky Driving Behavior (0.273), Environment and Traffic (0.222), Company Management (-0.227), and Government Regulation (-0.194). Vehicle factors did not show a significant influence. Based on these findings, two priority strategies validated by experts were formulated: (1) Transformation of the driving profession through standardization of competencies and vocational education, and (2) Restructuring of wage and incentive systems to improve driver welfare and eliminate economic pressures that trigger risky behavior. This study provides a theoretical contribution by comprehensively modeling the factors of AKAP bus accidents and providing strategic recommendations that can be used as a reference for the government and bus operators in formulating more targeted policies to improve road transportation safety

Abstract

Infrastructure development, particularly water infrastructure such as irrigation channels, plays a crucial role in regional development. In its implementation, construction safety becomes a critical aspect. The Construction Safety Management System (SMKK), as regulated in the Indonesian Ministry of Public Works and Housing Regulation No. 10 of 2021, serves as a guideline for ensuring safety in construction projects. One of the key components of SMKK is the accurate cost planning based on risk control programs for each activity, analyzed through a Work Breakdown Structure (WBS) approach. This research aims to develop a cost estimation of the SMKK using a Work Breakdown Structure (WBS)-based approach tailored to irrigation construction projects. The research includes identifying detailed work packages and activities, analyzing potential hazards and risks, formulating occupational health and safety (OHS) objectives and programs, and estimating SMKK costs in a case study of the DI. Saddang Irrigation Rehabilitation Project. The results provide a structured WBS framework, a comprehensive risk profile, and an estimated SMKK cost distribution, in which the largest portion is allocated to safety personnel, followed by training, personal protective equipment, and insurance.

Abstract

The Rehabilitation and Renovation of School Infrastructure program was initiated by the Indonesian Government through the Ministry of Public Works and Housing in 2019. Within this program, school categorized as low-risk buildings. However, field data show that construction-related accidents still occur frequently during implementation. This phenomenon is presumed to result from inadequate construction safety planning, particularly in the budgeting of Construction Safety Management System (CSMS) components. The main purpose of this research is to create a Work Breakdown Structure (WBS), pinpoint hazards and risks, propose strategies to mitigate these risks, outline objectives and plans, and establish cost factors in order to compute the percentage of CSMS expenditures associated with school restoration and refurbishment projects. A quantitative research method was employed to construct the questionnaire instruments from the initial to the final stage, starting with a literature review. Five construction safety experts validated these instruments. Risk levels were qualitatively assessed (Frequency × Severity) based on the evaluations of 30 respondents. The novelty of this research lies in its specific focus on school infrastructure as the project object. The Ministry of Public Works' school reconstruction and refurbishment initiatives necessitate budget allocations spanning from 2.63% to 4.52% of the Engineer's Estimate for CSMS expenditures.
