This research aims to improve the Overall Equipment Effectiveness (OEE) in the packaging process of cattle feed in an animal feed production facility by analyzing the causes of speed losses in the packaging process and identifying factors that affect speed to enhance machine efficiency. The research process began by collecting OEE data, which consists of three main components: Availability, Performance, and Quality. The analysis of the causes of losses using Pareto diagrams, fishbone diagrams, and Why-Why analysis revealed that the primary factor contributing to low overall effectiveness was the machine operating rate in the production process of feed sacks before packaging. The characteristics of the sacks frequently caused them to get stuck during the conveying process, resulting in frequent machine stoppages and reducing packaging efficiency. An improvement measure was implemented to address this issue by adding an inner layer of plastic to the packaging sacks, increasing the thickness from 6.7 millimeters to 9.7 millimeters. This improvement reduced the problem of the sacks getting stuck during conveying, and the overall equipment effectiveness increased.
