Abstract

PT. Chubb Safes Indonesia, a safe cabinet manufacturer, intends to improve product quality while increasing the process speed. Based on preliminary research, several waste types occur, including waiting, inappropriate processing and defects. The percentage of defects that reached 2.67%, exceeding the 100% defects based on the company's target of 1% became the basis of the problems in the company in this study. This study aims to use the Lean Six Sigma method to improve company performance. The Define – Measure – Analysis – Improve and Control (DMAIC) approach is the basis for the completion stage in this research. The Define stage is carried out by identifying the type of defect, then making a SIPOC diagram, then the Measure stage is carried out by making a control chart to determine whether the production process is running stably and making a Pareto diagram to determine the dominant defect level, DPMO calculation, Sigma level and PCE. Furthermore, at the Analysis stage, an Ishikawa diagram is made to find out the causes of the defects that occur, input information about the types of failures that occur as well as analysis of causes, effects and recommendations for improvement based on the FMEA table. check to reduce defective products. At the Control stage, the implementation of the proposed improvements is then compared to the results of the calculation of DPMO, Sigma Level and PCE before and after implementation. Based on data processing, the PCE obtained is 38.42% which increases to 51.5% and the sigma level increases from 3.5 to 4.8. With the sustainable use of the Lean Six Sigma method at PT CSI, it will improve performance according to company targets.
