<![CDATA[This study aims to evaluate the quality of plywood production at PT. SLJ Global Tbk using the Statistical Quality Control (SQC) approach, specifically through the application of the I-MR control chart. The data used were collected from the production output during September 2021. The analysis was conducted using both the Individuals Chart (I-Chart) and the Moving Range Chart (MR-Chart), complemented by a Pareto analysis to identify the most dominant types of defects. The results indicate that the overall production process is within statistical control limits; however, there is a violation of Western Electric Rule 4, suggesting a potential shift in the production process. The most dominant types of defects identified are Press Mark, Delamination, and Overlapped, which together account for over 75% of all detected defects. These findings highlight the need for targeted improvements in these areas to enhance product quality. The study is limited by a short observation period and lacks a thorough investigation into the root causes of the defects. Future research is recommended over a longer period and should incorporate root cause analysis to support comprehensive quality improvement efforts.]]>
