Abstract

Full Maintenance Contract (FMC) is one of the business lines of the service department of PT United Tractors Tbk. in performing maintenance on customers' heavy equipment. Machine availability is a high level KPI promised to customers with a minimum target written in the agreement. Downtime is the most influential thing on availability; therefore, we need the best maintenance strategy to manage downtime so that availability is achieved according to the target. Based on observation, there is a problem of availability not reaching the target in early 2022. Therefore, this study aims to develop a new maintenance strategy by using DMAIC approach. The root cause of the downtime is identified by using a combination of Pareto diagrams and why-why analysis, FMEA was used to find the Risk Priority Number, and 5W2H was used for planning improvement. The results the improvement was able to increase availability by 3.88%, from 91.90% to 95.78% (Minimum FMC Target 94.0%).
