Abstract

Excavator is the main tool in the mining process. If the excavator is damaged, it will affect the mining process, reduce production targets, the cost of repairing damage will be high, and in the end the company will suffer losses. At PT. United Tractors Semen Gresik, based on the company's historical data from January to December 2022, the effectiveness of the Excavator unit in Mine Operation Area 1 (Tuban site) averaged 57%, of the minimum OEE standard set by the company of 75%. So it is necessary to improve to meet company standards. The purpose of this research is to optimize the performance of excavators for limestone and clay mining at PT. United Tractors Semen Gresik. The method approach in this study is carried out by calculating availability, utilization and productivity idex, then the value of overall equipment effectiveness (OEE) can be identified. After obtaining the factors that affect excavator performance, optimization is carried out using fishbone diagram analysis. The results of the research conducted show that the average total value of Overall Equipment Effectiveness (OEE) is 70%, which is still below the OEE standard set by the company, which is 75%. The factors that have the most influence on the low effectiveness of the Excavator unit using the Overall Equipment Effectiveness (OEE) method analysis are the loss time, downtime, and actual productivity factors.
