Six Sigma has been utilised to analyse defects of fish steak processing at PT X located in North Jakarta. The tools of the Six Sigma implemented in the study were Define, Measure, Analyse and Improve. The observation was conducted for two months in 2020 before the company was temporarily shut down due to Covid-19 pandemic. Four defects were detected during the study, ie under size fish, softened meat, off odor and green coloration of meat, totaling 2,446 kg out of 15,080 kg of fish. Further analysis showed that the Sigma level was 3.24 with a Defect per Million Opportunities (DPMO) of 40,739. Some improvements were recommended based on cause-effect diagram.
