PT. XYZ is a company engaged in the rubber processing industry. The production process at XYZ company is wasteful in the form of non-value-Added activities. The types of non-value added activities contained in the production process are delays (waiting time), transportation, and defective products. In producing packing sterillizer, the company has a defective product there are bent, effervescence, and porous. The percentage of defect is 6.74%. Based on interviews with the company the tolerance given is 5%. This research uses lean six sigma approach and weighted product method. Activities that have no added value are waiting for compound activities to cutting station and transportation for packing sterilizer to cutting station. After estimating the improvement, an increase in sigma level is obtained, namely 3.51 to 3.65.
