This study was motivated by the occurrence of a belt conveyor tear in Area C26 at the Bontang Coal Terminal, which is managed by PT Indominco Mandiri, a subsidiary of PT Indo Tambangraya Megah Tbk. The incident caused significant disruptions to the coal loading process and resulted in substantial operational losses. This research aims to analyze the operational risks arising from the incident and to identify its causes, consequences, and the effectiveness of existing risk controls. The study employs a qualitative descriptive research design using the Bowtie Analysis approach, supported by field observations, semi-structured interviews, and document analysis. The findings indicate that the damage was influenced by several factors, including belt wear, conveyor misalignment, environmental conditions, the potential ingress of foreign objects, and limitations in early detection systems. The incident led to a seven-day suspension of loading activities, increased operational costs due to demurrage, and elevated occupational safety risks. The application of Bowtie Analysis generated recommendations to strengthen both preventive and mitigative controls, such as integrating real-time monitoring sensors to enhance operational reliability
