Background: In Indonesia, mining companies such as PT X, which has an IUJP for mineral exploration drilling, must implement SMKP Minerba. This system, which is aligned with government guidelines, includes seven elements such as Policy, Planning, Organization, Implementation, Evaluation, Documentation, and Review.
Research purposes: The objective is to analyse the effect of implementing the Mineral and Coal Mining Safety Management System (SMKP Minerba) on the work safety performance of Mineral Exploration Drilling Company at PT X.
Research methods: This study used a descriptive quantitative method and a case study approach, to analyse SMKP Minerba documents, including Mining Safety Performance records. Descriptive statistics, simple linear regression, and Pearson Correlation assessed variable impacts and relationships. From 144 engineers, the Slovin formula required a minimum sample of 98.
Research result: The study reported that the Internal Audit of the Mineral and Coal Mining Safety Management System (SMKP Minerba) achieved a score of 84.1%. Mining safety performance was evaluated across four key indicators. Worker Participation, Leadership Responsibility, Incident Analysis and Statistics, Occupational Diseases and Incidents, and Risk Control Efforts, yielding an overall score of 0.78 out of 1, placing it in the "Planned" category. Pearson correlation analysis indicated a positive association between Position, Tenure, and SMKP Audit Scores with Mining Safety Performance. ANOVA demonstrated a significant impact of Position and Tenure on Mining Safety Performance.
Conclusion: The study found that employees holding higher positions, possessing longer tenure, and achieving higher SMKP audit scores exhibited superior mining safety performance. The application of SMKP Minerba positively influences the safety performance in mining operations at PT X, contributing to the sustainable enhancement of mining safety practices in Indonesia.
