This study investigates the effectiveness of Total Productive Maintenance (TPM) implementation in Indonesian power generation companies using Overall Equipment Effectiveness (OEE) as an evaluative tool. The research focuses on power plants that have adopted TPM in maintenance operations. OEE values were calculated using standard formulas for Availability, Performance, and Quality, and analyzed based on the impact of the six big losses. Results show that only 25% of power plants achieved world-class OEE standards, while 67% remain in the normal category. Performance efficiency emerged as the dominant factor affecting OEE (60%), followed by quality (30%) and availability (10%). These findings indicate that TPM has not been optimally implemented, especially in minimizing performance-related losses.
