Abstract

The Andesite mining company experienced a deviation of 12.46% between demand and actual delivery. One of the reasons for the unmet production target was the reduced effectiveness of machinery, necessitating research to maximize production capacity for optimal company delivery. This study employed the Overall Equipment Effectiveness (OEE) method. Measuring the performance of a maintenance system was followed by the Maintenance Value Stream Mapping (MVSM) method to improve and enhance maintenance, visualize the flow of the maintenance process, and ensure facilities operate according to their functions.The research results indicated that the OEE value before improvement was 39.72%, which increased to 85.74% post-improvement. This improvement was attributed to the implementation of MVSM, which also influenced the Value Added (VA) metric. For the maintenance activities on the Conveyor gearbox, the initial VA value of 10.32% increased to 57.91%, the maintenance of the Motor Feeder went from an initial VA of 18.04% to 61.04%, and the Screen sieve replacement for 1-2 experienced an increase from an initial VA of 17.04% to 32.50%. The Conveyor small roller bearings maintenance maintained a constant VA value of 62.39%, while the Screen sieve replacement for 3-5 increased from an initial VA of 17.62% to 33.07%. The maintenance of Screen sieve replacement for 2-3 increased from an initial VA of 17.02% to 32.56%. The maintenance of the Jaw setting maintained a constant VA value of 20.78%, and the maintenance of the Conveyor large roller bearings also maintained a constant VA value of 41.78%.
