Analysis of quality control using statistical tools such as check sheets, control charts p, Pareto charts, cause-effect diagrams, and FMEA. Statistical tools are implemented to any existing stage in the PDCA cycle. P control chart analysis results indicate that the production activities are beyond the control limit. This can be seen in the map control where there are several points that have exceeded the upper and lower limits on the control chart. Additionally there are several points that experience jumping and looping on a control chart. From the analysis of cause-effect diagram, it can be seen the factors that cause defects in products derived from human factors, oven machinery, raw materials, environment, and working methods, so that the company can take corrective action to overcome these problems.
