Based on the description above, the goal to be achieved in this study is to determine the Statistical Quality Control (SQC) method with control chart techniques and cause and effect diagrams applied by the company in controlling quality to minimize failed products. The results of the SQC implementation contained data that was out of control. For those out of the upper control limit, the 4th period in August 2018 and the 6th period in October 2018 are Out of the Upper Control Line (UCL). The most influential factor in the occurrence of product defects is the machine and material factors that must be immediately corrected.
