Live Line Work (PDKB) on Medium Voltage (MV) networks is a maintenance method carried out without shutting down the electrical flow, yet it carries a high level of occupational safety risk. This study aims to analyze the factors influencing Occupational Health and Safety (OHS) performance in PDKB activities at PT PLN (Persero), focusing on four variables: hazard detection systems, management policy, facilities and infrastructure, and human resource (HR) awareness. A quantitative approach was employed using multiple linear regression analysis to examine the impact of each variable on OHS performance. The results show that out of the four independent variables examined, two have a significant influence on OSH performance, the hazard detection system (t-count = 3.611 > t-table = 1.708) and facilities and infrastructure (t-count = 4.068 > t-table = 1.708). Meanwhile, namely management policy (t-count = -0.571) and HR awareness (t-count = -0.706) do not show significant influence. These findings indicate that the success of OSH performance in PDKB TM is greatly influenced by the hazard detection system and the availability of adequate facilities, while the effectiveness of hazard detection and worker awareness needs to be improved. This study contributes to strengthening occupational safety management systems in the electricity sector.
