Abstract
PT Mitramulia Makmur is a plastic packaging manufacturing company that produces paint tubes for PT Avian. Based on field observations, the 25-liter Avitex Interior paint tube is the product with the highest number of customer complaints, especially related to dent tubes that cause returns, rework, and increased production costs. These problems are influenced by manual dimensional measurement, The position of the tube on the printing machine is not suitable, and waste in the inspection process. This research aims to identify waste, evaluate process performance, and propose improvements using the Lean Six Sigma approach. The methods used include Value Stream Mapping (VSM), Defect Per Million Opportunities (DPMO) analysis and sigma level based on Critical to Quality (CTQ), and Failure Mode and Effects Analysis (FMEA). The VSM results showed a total lead time of 270 minutes, with an average DPMO value of 26,173 and a sigma level of 3.45. The proposed improvements are projected to be able to increase Process Cycle Efficiency (PCE) from 53% to 59%. Further research is recommended to implement and validate the proposed improvement.
