Utilization or often called a theory of subjective value (subjective value theory). In general, utilization is the benefit obtained from consuming goods. Utilization is a measure of the benefits of an item compared to its alternative use. The actual number of products at PT.ABC during the July-September 2019 period was smaller than the target number of products. For example, in September 2019 the targeted number of products was 3,432 pcs, but actually in that month only 3,282 were achieved. This condition is the basis for analyzing the utilization of the Blasting Tower Type Chun Horng CH-100ZA machine, to determine the level of machine availability at PT.ABC. The calculation method that will be used is MTBF (Mean Time Between Falure), MTTR (Mean Time To Repair), Availability and Utilization. With a target of 91% machine availability, it will be able to produce 100% target utilization. After calculating, the Availability value in July was 95.81%, in August it was 97.63%, and in September it was 94%, so the target utilization of 100% should have been fulfilled.
