Abstract
This study aims to identify and measure the activity of waste that occurred, performance sigma value, and obtain solutions which do by the researcher in Consumer Packing Division PT Z. Waste is measured and assessed using the methods of Lean Six Sigma and Failure Mode and Effect Analysis (FMEA). Based on research, activity categorized waste activities include Defect, Waiting, Non Utilizing People-s Talent, Transportation, and Motion. Measurement focused on the largest waste Defect Broken Pack. The result showed DPMO value 4089.2475 with level sigma 4.14 and Index Capability Process Capability (Cp) 1.31. FMEA analysis showed 8 causes factors of the failure broken pack. Four failure mode of which exceeds the critical value that is less of a response operator (RPN = 150), lack of control of packaging (RPN = 126), less skilled workers (RPN = 120) and the inaccuracy of allocating the number of workers (RPN = 105). Therefore the provision of on the job training, proper allocation of workers during breaks, the packaging audit of the suppliers of packaging and increase the number of workers needed to support the efficiency of the flour packing process.
