Penerapan Total Productive Maintenance untuk Meningkatkan Efektivitas Mesin CNC Plasma Cutting di PT Panca Wahana Teknindo

Abstract

Mesin CNC Plasma Cutting memiliki peran penting dalam proses produksi fabrikasi logam di PT Panca Wahana Teknindo. Penelitian ini bertujuan untuk mengukur efektivitas dan keandalan mesin menggunakan metode Overall Equipment Effectiveness (OEE), Mean Time Between Failure (MTBF), Mean Time To Repair (MTTR), dan Mean Down Time (MDT). Analisis dilakukan menggunakan pendekatan Six Big Losses dan Root Cause Analysis untuk mengidentifikasi penyebab kerugian dan kerusakan mesin. Hasil penelitian menunjukkan nilai OEE tahunan sebesar 97,16% dengan availability 90,58%, performance 109,49%, dan quality yield 97,81%. Kerugian dominan yang ditemukan yaitu breakdown losses, reduced speed losses, dan process defect losses yang disebabkan oleh belum optimalnya inspeksi harian, pencatan checksheet, autonomous maintenance, dan preventive maintenance. Dengan demikian, Penerapan Total Productive Maintenance diharapkan dapat meningkatkan keandanlan dan efektivitas operasional mesin CNC Plasma Cutting.

The CNC Plasma Cutting machine has an improtant role in metal fabrication production process at PT Panca Wahana Teknindo. This study aims to measure the effectiveness and reliability of the machine using the Overall Equipment Effectiveness (OEE), Mean Time Between Failure (MTBF), Mean Time To Repair (MTTR), and Mean Down Time (MDT) methods. The analysis was conduted using the Six Big Losses and Root Cause Analysis approaches to identify the causes of losses and machine failures. The results showed that the annual OEE value was 97.16%, with availability of 90.58%, performance of 109.49%, and quality yield of 97.81%. The dominant losses found were breakdown losses, reduced speed losses, and process defect losses caused by suboptimal daily inspections, checksheet recording, autonomous maintenance, and preventive maintenance. Therefore, the implementation of Total Productive Maintenance is ecpected to improve the reliability and operational effectiveness of the CNC Plasma Cutting machine.
