The purpose of this study is to see the quality control of defective products during the production process through visualization in the form of a demerit control chart. The demerit control chart begins by determining the weight for each type of bread, then calculating the demerit value for each subgroup, followed by determining the centerline, upper center line, and lower center line, and ends by visualizing the number of defective products using the demerit control chart. The results showed that the quality of the Fit O Mini, Chocolate Special, and Fit O Vanilla products was still under control. This can be seen in the degree of membership in each subgroup which is still present in the upper and lower limit intervals of the demerit diagram.enDemerit control chartquality controlrotteArticle
