Indonesia Indonesia has the second-largest geothermal power capacity in the world, reaching 2,133 MW in 2020 and contributing 3.01% to the national electricity production. Geothermal power plants (PLTP) constitute an industry with high risks, particularly during the wellpad exploration stage. According to the annual report from BPJS, the number of work-related accidents in Indonesia remains alarmingly high, with a continuous increase from 101,367 cases in 2016 to 265,334 cases in 2022. This research aims to compare safety risk management in wellpad (exploration & exploitation) and power plant areas, referencing the Hazard Identification, Risk Assessment & Risk Control (HIRARC) method. It begins with the utilization of Job Safety Analysis (JSA) to facilitate hazard identification corresponding to job stages, followed by risk assessment. Hazard identification data from JSA are integrated into the HIRARC method to conduct risk assessment and formulate risk control recommendations in wellpad and power plant areas based on calculation results and risk mapping. Data processing using HIRARC and questionnaire data reveals that the rig project area (exploration) is the only area with hazards categorized as high, and it also has the highest total number of hazards, followed by the power plant area and wellpad area (exploitation).
