Abstract

This study aims to analyse the critical factors causing delays in the Provincial Road Grant Program (PHJD) road construction project in North Toraja Regency, particularly on the Pangala-Baruppu-West Sulawesi road segment, using the Relative Importance Index (RII) method. Data were collected through questionnaires completed by 34 respondents directly involved in the project, including contractors, supervising consultants, and other related parties. The results of the study show that the most significant cause of delays in the PHJD road construction project was material testing delays, with the highest RII score of 0.888. Other key contributors were material delivery issues, ineffective coordination, and unpredictable weather. Financial issues had a medium impact, while factors like low labor productivity and lack of GS responsibility were less influential. Design changes and land acquisition were the least significant. The findings emphasize the need for improved coordination, efficient material handling, and better preparation for environmental challenges to minimize delays and enhance project performance.

Abstract

The construction of substations is one of the most crucial electrical projects in the development of infrastructure and economic growth, to ensure a stable, reliable, and equitable supply of electricity. Electrical construction projects inherently present significant occupational safety and accident risks, ranging from exposure to high voltage to incidents involving heavy equipment. In Indonesia, the Occupational Safety and Health (OSH) Management System known as SMK3 is mandated by Government Regulation (PP) No. 50 of 2012, and serves as the national framework for mitigating these dangers. The goal for implementing this system is to prevent and minimize human and financial losses, including lost work hours and declining productivity, thereby supporting more effective and efficient operational performance. In this study, the implementation of SMK3 on the 150 kV Raha Substation project was evaluated using a descriptive qualitative method with employing data collection instruments that included interviews, field observations, and a checklist of questions based on the audit criteria elements outlined in applicable regulations. The implementation of SMK3, based on 166 audit criteria in the Raha 150 kV Substation construction project, as per PP No. 50 of 2012, achieved a compliance rate of 92.17% (153 criteria compliant and 13 criteria non-compliant), categorized as satisfactory category. From the analysis of respondent interviews and field observations, it was found that the main factors causing obstacles to the optimal implementation of OSH in general are low employee understanding, budget constraints, lack of standardization among subcontractors, and disparities in employee competencies.
