<![CDATA[The development of the manufacturing industry requires companies to improve the efficiency of the production process and maintain product quality stability. PT XYZ, a zipper manufacturer, faces a problem with a high Tape Jam Alarm ratio on its CM7 chain making machine, which has an impact on decreasing productivity. Based on three months of production data collection, it is known that the Tape Jam Alarm ratio reaches 8 times in every 1000 mD. This condition indicates an uncontrollable process and the need for an in-depth analysis of the causes of the disturbance. This study aims to identify the root cause of the Tape Jam Alarm and formulate corrective actions that can reduce the alarm frequency. The analysis method used is a Fishbone diagram to trace the causal factors originating from the aspects of the machine, material, method, and work environment. The results of the study indicate that the Tape Guide component on the CM7 machine has a gap that is too narrow and the surface is still rough, causing excessive friction and triggering tape jams. Based on these findings, corrective actions were taken by replacing the Tape Guide with a design that has a wider gap and a smoother surface. After the implementation of the improvements, the Tape Jam Alarm frequency was successfully reduced from 8 times to 2 times in every 1000 mD. Research on reducing tape jam alarms through modifications to the tape jam guide design on the machine is still limited. This research provides a contribution in the form of recommendations for repairing critical components on the CM7 engine and can be used as a reference in efforts to increase the efficiency and reliability of the production process at PT XYZ Keywords: Corrective actions; production; CM7]]>
