Abstract
The objective of this research is to improve the efficiency of the outbound logistics process for inventory management at the warehouse of a plastic pellet manufacturing factory, which serves as a case study. The study began by analyzing the process of issuing document A using time study, flow process chart, flow chart, and brainstorming to identify two problems. 1) The lack of clear storage locations for inventory, resulting in waste in the outbound logistics process. The proposed solution was to prioritize inventory using ABC analysis to reduce the time required for outbound logistics and to redesign the warehouse storage space. 2) The lack of product labeling, resulting in waste in the search process for inventory in the warehouse. The proposed solution was to use visual control tools to label products. The solution was to use visual control tools to label products. The research found that before the improvement, the time required for issuing document A was 2,085.21 seconds and the distance traveled was 425 meters. After the improvement, the time required was reduced to 1,484.77 seconds and the distance traveled was reduced to 165 meters, a decrease of 600.44 seconds or 28.80%, and the distance traveled was reduced to 260 meters, a decrease of 61.18%.
