Abstract

This research aims to improve the production process of Japanese flagpoles for vinyl signboards by applying the ECRS waste reduction principle to minimize production time and distance while establishing a standardized process. The study begins with an analysis of the current production process using flow process charts and diagrams. Subsequently, data was analyzed to identify the root causes of inefficiencies through brainstorming sessions with stakeholders, utilizing a fishbone diagram. The ECRS principle is then employed to pinpoint waste factors and optimize the production process into
a standardized workflow. The research results are evaluated based on reductions in the number of operational steps, time, and distance. The findings reveal that before the improvement, the production process consisted of 39 steps, taking 12 hours, 4 minutes, and 29 seconds, with a total production distance of 176 meters. After the improvement, the number of steps was reduced to 29, the production time decreased to 8 hours, 45 minutes, and 7 seconds, and the distance was shortened to 127.5 meters. This represents a 25.64% reduction in operational steps, a 27.52% decrease in production time, and a 27.56% reduction in production distance. In conclusion, the application of the ECRS waste reduction principle effectively enhances production efficiency and improves the competitiveness of the manufacturing process.
