Lean Manufacturing Implementation to Reduce Rejecton Part Step Floor with DMAIC and FMEA approach

In this study, the problem is focused on Cikarangplant, especially department warehouse 5 which currently producing a new variant, K2FA type. Because mass production time for type has not been running long time, there are still many adjustments that need to be made in work process order create good effectiveness and efficiency. This reflected one of supply processes, namely preparation plastic eating step floor, because it was found an additional process, unpacking train handling facilities were considered inadequate, causing problems manpower area. begins with high number reject parts reach total 11.5% percent months, therefore potential existing rejects must identified minimize causes waste as goal study. The analysis phase carried out using DMAIC method (Define, Measure, Analyze, Improve, Control), use FMEA improvement (Failure Mode Effect Analysis). results study expected suggestions minimizing waste.
