The purpose of this study is to measure the machine’s performance in the filling process which often experiences damage to one of the companies engaged in the food sector that produces coffee and goat milk powder sachet packaging. The company targets the production process results on coffee products as much as 15,600 sachets per day. In Filling Line 3 machines, there are often losses caused by machine breaks, so the daily production target is not achieved. The method used is the machine performance measurement method (OEE) which consists of 3 factors, namely Availability, Performance, and Quality. The results of the study were obtained from the Overall Equipment Effectiveness (OEE) value for the period of December 2021 (53.4%), January 2022 (60.6%), February 2022 (61%), and March 2022 (63.3%). The OEE value obtained from the calculation is still too far from the World Class standard (85%). The factors in the Six Big Losses analysis that caused the low OEE value consisted of Equipment Failure (52.7%), and Setup & Adjustment (30.7%). The proposed improvements that can be used to increase the effectiveness value of the machine include that the company must conduct training for employees and add maintenance operators. Making SOPs for workers must also be considered because SOPs are standards passed by the company to be followed. The company must also monitor the engine components used.
