Poka-Yoke in the production process of car seat parts

Abstract

This research is Poka-Yoke in the production process of car seat parts. The objectives are 1) to develop waste detection to prevent errors in the production process of automotive seat parts. 2) to study the efficiency of a drill hole inspection machine to prevent errors in the production process of automotive seat parts. Find problems using brainstorming techniques to find the root cause of the problem. Fishbone diagram to find solutions and use Poka-Yoke technique to develop waste detection to prevent errors in the production process of cushion parts. Data was collected during July-November 2022, comparing before and after data. Statistics using percentages. From the study it was found that before building a drill hole inspection machine Total production volume was 22,000 pieces. Work delivered to customers was 22,000 pieces. Found defective work delivered to customers 295 pieces, accounting for 1.34% of defective work passed to customers. After using the drill hole inspection machine, it was found that there was a production volume of 36,000 pieces, and 321 pieces of defective work were found to be delivered to the customer, accounting for 0.89%.
