ANALISA TERTUNDANYA BONGKAR MUATAN BATUBARA DI JETTY PLTU MENGGUNAKAN METODE HOUSE OF RISK

Abstract

This study aims to analyze delays in coal unloading at the PLTU jetty using the House of Risk (HOR) method at PT Adhi Guna Putera. According to company data, in 2024, there were delays in coal unloading every month. This resulted in the company incurring additional operational costs of Rp. 776,000 per hour. In this study, the House of Risk (HOR) method was used to analyze risks and determine risk mitigation strategies. The data collection techniques used in this study were interviews and questionnaires with company experts to determine risk agents and risk events. The results of the House of Risk (HOR) calculations were used to determine the priority of recommended corrective actions to effectively minimize and prevent delays in coal unloading at the Pacitan PLTU jetty. The research results on cargo unloading delays identified 13 risk events, including coal that cannot be unloaded (E1), and 21 risk agents, including coal catching fire during the unloading process (A1). The results of Phase 1 HOR processing, as depicted in the Pareto diagram, identified 13 dominant risk agents with the highest ARP value at A17, 159.84, related to issues with the unloading hopper and conveyor routes. In Phase 2 of the HOR, 19 mitigation actions were identified, with the highest ETD (Effectiveness to Difficulty Ratio of Action) value at PA1 of 857.7, which involves conducting inspections.
