Abstract

The motivation for this study is to improve the organization of the spare parts storage area in the CGS unit. Previously, there was no system for controlling the entry and exit of stored goods, leading to disorganization. The researcher sought to address this issue by developing control documents and establishing a well-organized storage system for incoming and outgoing goods. The research methodology is based on the principles of Kaizen and PDCA and employs various tools, including stock card sheets, stock summary sheets, and SOP sheets. The researcher developed a spare parts document control system that effectively regulates goods’ entry and exit in the CGS unit’s storage area by implementing these tools. Overall, the researcher successfully developed a spare parts document control system that has significantly improved the organization of the CGS unit’s spare parts storage area, proven by the decrease in the number of errors that occur by 80%. The system has ensured that the entry and exit of stored goods are managed and documented, leading to a better-organized storage area.
