Preventive maintenance approach for improving the efficiency of SCM Olimpic K-800 Auto Edgeband machine

This study aims to improve the efficiency of the SCM Olimpic K-800 Auto Edgeband machine at PT ABC, a furniture manufacturing company. From January to June 2024, frequent machine breakdowns disrupted production flow and reduced productivity. The main problem identified was low machine effectiveness, measured using the Overall Equipment Effectiveness (OEE) method, with an average value of 74%, below the world-class standard of 85%. The research contribution is the development of a cost-efficient preventive maintenance schedule that minimizes downtime and improves production reliability. The study applied a quantitative approach using OEE and Six Big Losses analysis to identify the main causes of inefficiency. Results show that the largest loss (58.4%) was due to reduced speed losses. Preventive maintenance scheduling was then developed by classifying spare parts into A (20%), B (30%), and C (50%) cost categories. The proposed maintenance intervals are every 6 months for class A and C, and every 5 months for class B. Cost comparison showed that preventive maintenance reduced total expenses by 25–30% compared to the repair maintenance method. Therefore, implementing a preventive maintenance policy can increase machine effectiveness, reduce costs, and ensure smoother production operations.
