The results obtained are 6characteristics Critical to Quality with a DPMO value of 4,999,165 and the sigma value of 4.075887 in January 2020-February 2021. From the results of FMEA obtained 3 causes with the highest RPN value obtained from 3 defects, namely packaging vacuum leaking, uneven CO gas andengine program metalerrors. The suggested improvements are making a logbook to check the condition of the machine regularly, making a checklist to carry out tighter supervision of employees and calibrating the program by QC every time they do packing. After carrying out thestage control, the DPMO value added is 212.560 and Sigma is 5.023978. So it can be concluded that the application of themethod six sigma as a quality control control can reduce the DPMO value by 12.75%.]]>
