Calculation of Centrifugal Pump Effectiveness Using The Overall Equipment Effectiveness (OEE) Method at PT. Permata Hijau Group

Centrifugal pumps often experience downtime due to damage, which disrupts the production process. By applying the Overall Equipment Effectiveness (OEE) method, it is expected that the factors causing decreased pump efficiency can be identified, and strategies and corrective actions can be formulated to improve the operational efficiency of centrifugal pumps at PT. Permata Hijau Group from May 2024 to April 2025. The research results showed that the OEE values each month were above the JIPM standard of 85%, with the highest value in February 2025 at 88.15% and the lowest in July 2024, September 2024, January 2025, and March 2025 at 85.34%. The biggest losses came from reduced speed losses at 8.32% and idling and minor stoppages losses at 6.96%. Based on a fishbone analysis, the main cause of high breakdown time in the Hydrogenation division of PT. Permata Hijau Group is the lack of scheduled preventive maintenance, indicating a need for the company to reorganize its maintenance schedule.
