Strategies to Improve Machine Maintenance Effectiveness to Minimize Downtime at PT. MNO, a Tableware Ceramics Manufacturer

The objective of this research is to enhance the productivity of PT MNO to reduce the downtime, as it can be done by good machine maintenance strategy. This study is a mixed method research by analyzing data on some machineries with critical conditions of the Kiln and Oven at PT MNO for 2022 - 2024 using Overall Equipment Effectiveness and root cause analysis. The study’s findings reveal a decline in OEE of 42.75% by 2024 due to the “Best tools oldest” affecting availability of spare parts. Strategic improvements with method 5W+1H: are to gain the OEE and bring back to 79% that year. The contribution implication of this research is to provide as a reference stakeholders, PT. MNO, and State-Owned Enterprises to maintain the stable supply of national ceramic product.
