Optimasi Kinerja Mesin Hot Press Di PT. XYZ Melalui Penerapan Metode Overall Equipment Effectiveness (OEE)

Abstract

PT. XYZ is a company engaged in manufacturing wood for the international market. In an effort to maintain competitiveness and operational efficiency, the company continues to evaluate the performance of production machines, including hot press machines that play an important role in the production process. This study aims to analyze the performance of hot press machines at PT. XYZ using the Overall Equipment Effectiveness (OEE) method, identify factors that affect operational efficiency based on OEE and Six Big Losses analysis, and provide recommendations for improvement to increase efficiency and productivity. The OEE method is used to evaluate the level of machine effectiveness, while the Six Big Losses analysis identifies the biggest types of losses. The FMEA method was also applied to prioritize improvements based on the most significant potential failures. The results showed that the OEE value of the hot press machine reached 82.21%, lower than the international standard of 85%. The biggest loss was caused by reject/rework of 6%, which mainly occurred because the veneer did not stick perfectly to the veneer joint core lamination (VJCL). Further analysis used fishbone to identify the main weaknesses in the veneer attachment process. As a solution, it is recommended to add automatic air spray on the conveyor before the material enters the hot press machine, to ensure maximum veneer adhesion. This strategy is expected to reduce reject/rework losses, improve machine efficiency, and bring the OEE value closer to international standards.
