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.
