Abstract
This research was conducted at PT PLN Nusantara Power UP Gresik, one of the power plants in East Java, focusing on improving the effectiveness of the High Pressure Boiler Feed Pump (HP BFP) at the Gas and Steam Power Plant (PLTGU) Block I. The main issue faced was the high level of waste in the maintenance process, which resulted in a low Overall Equipment Effectiveness (OEE) value. To address this, the Lean Maintenance method was applied in combination with Value Stream Maintenance Mapping (VSMM), Mean Time Between Failure (MTBF), Mean Time to Repair (MTTR), and Root Cause Failure Analysis (RCFA) to identify waste and design improvement proposals. The research results indicated dominant waste in the form of Unproductive Work, Delay in Motion, and Poor Inventory Management. After implementing the improvement recommendations, there was a significant increase in OEE values for each HP BFP unit: HP BFP 1A from 67% to 86%, HP BFP 1B from 52% to 86%, HP BFP 1C from 62% to 86%, and HP BFP 1D from 57% to 87%, as well as a reduction in maintenance time from 9,780 minutes to 3,300 minutes. This study demonstrates that the implementation of Lean Maintenance can enhance operational efficiency and significantly reduce machine downtime.
