Analisis Perbaikan Metode Pemeliharaan Mesin untuk Peningkatan Target Produksi Box Panel Listrik

Abstract

Machine maintenance is an important factor in maintaining operational efficiency and preventing losses due to downtime. PT Rahmat Kurnia Abadi is a company engaged in the manufacturing of electrical panel boxes. Based on the research conducted, the company is facing issues with not meeting production targets. The average percentage of production target achievement for the year 2023 is 68%, with the company's tolerance set at 85%. The main cause of this failure is attributed to downtime during machine maintenance activities, which increased downtime by 2.40%. As a result, maintenance activities led to increased time and costs in maintenance operations. This research aims to analyze the improvement of machine maintenance methods by reducing downtime frequency using a lean maintenance approach. Lean Maintenance is an approach aimed at reducing waste, downtime, costs, and improving efficiency in maintenance operations. The methods used in lean maintenance are maintenance value stream mapping (MVSM), maintenance intervals, and lean probability. The results obtained show two wastes that increase maintenance time, namely waiting for maintenance resources and unnecessary motion. Downtime reduction is achieved by scheduling maintenance for 57,559.0 minutes and a repair duration of 133.75 minutes, resulting in a decrease in downtime frequency of 236 minutes from 390 minutes. A decrease in maintenance costs of IDR 8,781,691 from IDR 11,447,621. Improvements in machine maintenance methods carried out through lean maintenance resulted in an increase in maintenance efficiency of 86.36% and a production target increase of 6.36%.
