K3 Risk Assessment Using FMEA Method at PT Pertama Mina Sutra Perkasa Jember in Crushing Plan 1, Crushing Plan 2, Mine Quarry and Workshop Area

Abstract

This study aims to identify potential hazards, assess Occupational Safety and Health (OSH) risk levels, and provide recommendations for improving the risk management system at PT Pertama Mina Sutra Perkasa Jember. The research data were obtained through field observations, interviews with workers and related personnel, company documentation, and questionnaires. These data were used to identify workplace hazards, evaluate risk levels, and calculate the Risk Priority Number (RPN). The method employed was Failure Mode and Effect Analysis (FMEA), a risk assessment technique that determines RPN values based on severity, occurrence, and detection parameters. The calculated RPN values were then prioritized to determine which hazards required immediate mitigation. The results revealed several hazards with high RPN values, including falling from heights, being trapped in machinery at the crushing plant, and electrical panel fires in the workshop area. Pareto diagrams were applied to establish hazard mitigation priorities. Recommended improvements include strengthening supervision, enforcing the mandatory use of appropriate Personal Protective Equipment (PPE), and conducting regular inspection and maintenance of equipment. In conclusion, the application of FMEA effectively identifies OSH risks systematically, establishes priority scales for mitigation, and provides corrective measures to minimize potential workplace accidents. Implementing these recommendations is expected to enhance workplace safety and health while supporting company productivity.
