Manajemen pemeliharaan mesin filler menggunakan metode Overall Equipment Effectiveness di production house area nursery PT. RAPP

Abstract

Maintenance system is an activity conducted to ensure that machines or equipment are always ready to use. PT. RAPP uses a filler machine in the nursery area to fill cocopeat media into trays. The filler machine works optimally at a capacity of 600 kg (multiplied by two cycles) to fill 180 trays per day. When experiencing damage, this filler machine can only be used at a capacity of 300 kg (multiplied by four cycles) to fill 150-165 trays per day. To reduce machine downtime when there is damage, the implementation of machine maintenance management is needed. OEE is a method used to calculate machine effectiveness based on availability, performance, and quality. Using data from May 2022 to April 2023, the average OEE value obtained is 60.66%, indicating that the filler machine performance is below the standard of 85%. The calculation of the Six Big Losses shows that the values affecting machine performance are breakdown losses with a time loss of 22,825 minutes, rework losses with a time loss of 15.8 minutes, and setup and adjustment with a time loss of 41.8 minutes, indicating that the largest factor and the main cause affecting the OEE value of the filler machine is breakdown losses, which reduces the production rate.
