Real-Time WIP Shelf-Life Tracking with Barcode Technology for Defects Reduction

Manual labeling of product information in the wafer production line at PT XYZ failed to meet secure tracking and tracing requirements, resulting in increased defects. To solve this problem, the author used the Gemba Kaizen approach as a tool companies use for continuous improvement achieved through low-cost steps. Our main idea is to introduce alternative technologies by developing real-time applications to track WIP (Work-in-process) movement information in production. This barcode technology uses low-cost technology and has proven effective in helping production supervisors speed up decision-making of WIP management and minimize the risk of process failure in production that causes an increase in the number of defects. The results showed that the real-time system can reduce the number of defects from 2.6% to 1.6%. This can optimize overall inventory management and provide valuable insights for manufacturing companies looking to improve their operational efficiency through low-cost technology and real-time monitoring.
