The Overall Equipment Effectiveness (OEE) analysis in minimizing the Six Big Losses: An effort to green manufacturing in a wood processing company

Abstract

A company needs an appropriate maintenance management system to conduct production process effectively and efficiently. However in reality, the maintenance actions that have been taken result in losses because employees who carry out maintenance actions do not know with certainty the factors causing damage to the machine. This study was conducted to measure the level of effectiveness and analyze the factors that cause the low effectiveness of NC-Router machines. The aim is to provide recommendations for improvements in the maintenance so that six big losses can be reduced. The method used for this research was the Overall Equipment Effectiveness (OEE), which focuses on measuring the effectiveness level to prevent the loss of production time caused by breakdown on the machine. After OEE has been implemented, the overall equipment effectiveness on NC-Router machines at PT. Maruki International Indonesia, a wood processing company, for twenty periods production was 61%. The main factors causing the low OEE value on the machine were the reduce speed factor of 61.21%, as well as the idle and minor stoppages of 31.03%.
