Abstract

Maintenance management in the transportation sector is crucial for ensuring operational continuity and minimizing safety risks. This study transitions the maintenance program for bus engine components at PT. Bukit Barisan Transport from a reactive schedule to an optimized proactive strategy. Utilizing historical failure data, the research combines Failure Mode and Effects Analysis (FMEA) to identify criticality, the Weibull distribution to quantify reliability and failure patterns, and the Reliability-Centered Maintenance (RCM) logic to select suitable maintenance tasks. Three critical components—Air Compressor, Fan Belt, and Fuel Filter—were analyzed. Weibull analysis revealed that all three exhibit a wear-out failure pattern (β > 1), justifying time-based scheduled tasks. Consequently, the RCM approach optimized preventive maintenance intervals to 41 days (Air Compressor), 32 days (Fan Belt), and 21 days (Fuel Filter), improving system reliability (toR(t) ≥ 80%) and establishing a cost-effective, risk-prioritized maintenance program.
