<![CDATA[Problems: The machines used for the production of concrete include welding machines, concrete mixer machines, spinning machines, and mobile hopper machines. Of the machines that have experienced disturbances in the production section, are batching mixer machines. Batching mixer machines are used for mixing sand, coral and cement raw materials. Problems often occur in batching mixer machines because there are often some problems or machine damage. The batching mixer which is often damaged, the batching mixer is the end part of the batching plant machine which functions as a machine for mixing and mixing concrete raw materials. Mixer batching machines often experience downtime and breakdown of 865 minutes and breakdown of 265 minutes in 9 months from January to September 2022. Purpose: Using the Overall Equipment Effectiveness (OEE) method, this study aims to identify the factors that contribute to breakdowns and downtime on mixer batching machines and to assess the level of machine utilization efficiency. Methodology: This research uses descriptive analysis method through field research. Results/Findings: The cause of the high value of downtime which causes a low overall equipment effectiveness value of 82%, it is necessary to carry out operator training regarding the machine being handled, increasing the intensity of maintenance of the Batching Plant machine due to the high Batching Plant machine working hours of 90%, causing a low Performance Rate value, namely by 88% for nine months in January - September 2022, the low Performance Rate value is the main cause of the OEE value on Batching Plant machines getting an average value of 82%.]]>
