This study addresses the challenges posed by the increasing proportion of lowerranking coal through proactive risk management in the Coal Preparation Plant (CPP) area of PT. XYZ, specifically during crushing, conveying, stockpiling, and reclaiming activities. Previous failures in handling lower-ranking coal have led to production delays and negatively impacted the coal handling process. The study focuses on comprehensively identifying, assessing, and prioritizing risks, and formulating optimal solutions to minimize their impact. The primary benefit of this study is its proactive approach to risk management, addressing potential issues based on the risk rank before they lead to incidents. The study uses quantitative and qualitative techniques, collecting primary data from CPP stakeholders through discussions, interviews, and questionnaire along with secondary data from external sources and internal documents. The methodology includes Failure Mode Effect Analysis (FMEA) to identify and rank risks. Subsequently, the top three risks are proposed along with alternative solutions. The methodology then proceeds with The Analytic Hierarchy Process (AHP), guided by criteria from Value-Focused Thinking (VFT), to determine the most optimal solution. The top three identified risks and their corresponding solutions are: (1) Sticky material adherence to the drawdown hopper and chute wall causing material flow blockage and overfill, addressed by installing a booster pump on the existing water suppression system. (2) Accumulation of fine coal in closed spaces causing equipment burning, mitigated through periodic cleanup using a new portable blower or water. (3) Burning coal causing fires inside the tunnel, resolved by installing a thermal camera monitoring system. This study provides valuable guidelines to CPP stakeholders for minimizing disruptions and improving the overall effectiveness of coal handling activities.
