Maintenance of company facilities or machines has an important role in supporting work productivity within the company in order to achieve the production targets that have been set. Results Based on the research conducted, it can be seen that PT. XYZ has problems with the current maintenance system. The problem that still occurs is that there is still waste in its maintenance activities. PT. XYZ is a company engaged in the garment sector and has been established since 2003. The products produced by PT. XYZ, namely, polo shirts, t-shirts, sweaters, shirts, field service clothes (PDL) and jerseys. One of the damages is the overlock machine which has a downtime per year from January 2020 to December 2020, which is 11944 minutes. The data is carried out using Maintenance Value Stream Mapping (MVSM) to trace the causes of waste in maintenance activities which will then be deepened with Root Cause Analysis (RCA), which uses five-whys analysis and fishbone diagrams to recommend improvements in these wasteful efforts. Based on the recommendations for improvement, the maintenance efficiency of the servo motor component has increased from 36.36% to 42.90%, while the looper component has increased maintenance efficiency from 24.27% to 32%.
