| Abstrak The increasing competition in the industrial sector requires companies to maintain consistent product quality. One of the problems faced by Trans Batako Palu is the presence of defective bricks in its production process. This study compares the performace of the decision on belief (DOB) and Progressive mean (PM) control charts controllingthe quality of brick production at Trans Batako Palu. The data used in this research is primary data, obtained from the number of defective bricks over 30 days of production. The analysis was conducted by calculating observation points, BKA, BKB, and GT, as well as comparing the number of out of control points in each control chart. The analysis results indicate that the DOB control chart has a higher level of sensitivity in detecting production defects, with 9 out of control points identified, while the PM control chart detects only 5 out of control points. Based on these results, the DOB control chart is considered more effective in identifying quality issues in concrete block production and is recommended for use in the company’squality control process. |
