Abstract

Loading and unloading activities involve a high risk of accidents, particularly in the operation of wheel loaders, bulldozers, and ship cranes, thus requiring strengthened occupational safety and health (OSH/K3) competence and optimal equipment maintenance. This study aims to examine and analyze the effect of OSH knowledge and heavy equipment maintenance for ship-based loading and unloading on hazard control and its implications for occupational safety at the work area of PT Puradika Bongkar Muat Makmur Laut Taboneo, South Kalimantan. The study employed a quantitative approach with a cross-sectional design. The population consisted of 53 wheel loader and bulldozer operators (organic employees) and 50 ship crane operators (subcontract workers), totaling 103 respondents using a total sampling technique. Data were collected through questionnaires and OSH report documentation, and analyzed using SmartPLS. The results indicate that OSH knowledge and heavy equipment maintenance have a positive and significant effect on hazard control, with equipment maintenance showing the most dominant influence. Furthermore, OSH knowledge, equipment maintenance, and hazard control have positive and significant effects on occupational safety, both directly and indirectly through hazard control as a mediating variable. These findings highlight that improved risk understanding, effective condition monitoring, and the implementation of technical controls contribute to reducing workplace accident potential in loading and unloading operations. The study recommends enhancing emergency response training through simulation-based programs, strengthening digital-based spare parts management systems, and optimizing engineering controls in the work area to minimize risks. In addition, reinforcing behavior-based safety programs and conducting periodic safety evaluations are essential to reduce accident rates and property damage. These strategies are expected to improve occupational safety performance in a sustainable manner.

Abstract

This study aims to analyze the effect of safety training and safety knowledge on crew competence and its implications for occupational safety on board ships at PT. Gelora Persada Makmur. This research employs a quantitative research design using a survey method with a cross-sectional approach. The population of this study consists of all ship crew members of PT. Gelora Persada Makmur, totaling 100 respondents. A saturated sampling technique was applied, in which the entire population was used as the research sample. Data were collected through a closed-ended questionnaire using a five-point Likert scale distributed online. The collected data were analyzed using the Structural Equation Modeling–Partial Least Squares (SEM-PLS) method with the assistance of SmartPLS software. The results of this study are expected to indicate that safety training and safety knowledge have a positive effect on crew competence, both directly and indirectly, and that crew competence has a positive effect on occupational safety on board. These findings are expected to serve as a basis for improving operational safety management within the company
