PT XYZ is oil industry that processes CPO from oil palm, with a daily production target of 1,000 tons and a flow rate of 41.67 tons per hour. However, in 2019, the actual flow rate fell short of expectations. This study aims to improve equipment effectiveness in the refinery division through enhanced machine maintenance. Using the OEE method, the study identifies machines with the lowest effectiveness for priority improvement. Analysis of these machines, integrating OEE, FMEA, and TPM, reveals that the Niagara filter machine has the lowest effectiveness. The OEE value is 82.14%, primarily due to breakdown losses and idling minor & stoppage losses. Based on the highest RPN values, three improvement proposals are suggested. Such as routine field checking on every shift, scheduling system for maintenance processes, and training operators about how to always ensure and control the pressure when operating the machine. So, this improvement expected to raise the OEE more to 84.16%.
