ANALISIS TOTAL PRODUCTIVE MAINTENANCE PADA PROSES PENGECORAN UNTUK MENINGKATKAN KINERJA MESIN PEDESTAL MIXER OMEGA 300 DI PT XYZ

Abstract

Gangguan yang terjadi pada mesin Pedestal Mixer Omega 300 di bagian moulding, khususnya pada komponen selang pneumatic, dapat memengaruhi kelancaran proses produksi. Penelitian ini bertujuan untuk menganalisis penerapan Total Productive Maintenance (TPM), efektivitas mesin menggunakan metode Overall Equipment Effectiveness (OEE), tingkat keandalan mesin menggunakan Reliability Maintenance, serta memberikan usulan perbaikan pada mesin Pedestal Mixer Omega 300 di PT XYZ. Metode penelitian menggunakan pendekatan deskriptif kuantitatif melalui observasi, wawancara, dan dokumentasi. Analisis dilakukan menggunakan metode OEE, Mean Time Between Failure (MTBF), Mean Time To Repair (MTTR), Mean Down Time (MDT), dan Root Cause Analysis (RCA). Hasil penelitian menunjukkan bahwa efektivitas mesin Pedestal Mixer Omega 300 masih belum optimal dengan nilai OEE sebesar 56%. Komponen selang pneumatic menjadi penyumbang unplanned downtime tertinggi. Hasil analisis menunjukkan nilai MTBF sebesar 1056 menit, MTTR sebesar 30 menit, dan MDT sebesar 99 Menit. Usulan perbaikan diberikan melalui pembuatan One Point Lesson (OPL) dan checklist Autonomous Maintenance.

Disturbances occurring in the Pedestal Mixer Omega 300 machine in the moulding section, particularly in the pneumatic hose component, may affect the smoothness of the production process. This study aims to analyze the implementation of Total Productive Maintenance (TPM), machine effectiveness using the Overall Equipment Effectiveness (OEE) method, machine reliability using Reliability Maintenance, and to provide improvement proposals for the Pedestal Mixer Omega 300 machine at PT XYZ. The research method used a quantitative descriptive approach through observation, interviews, and documentation. The analysis was conducted using the OEE method, Mean Time Between Failure (MTBF), Mean Time To Repair (MTTR), Mean Down Time (MDT), and Root Cause Analysis (RCA). The results showed that the effectiveness of the Pedestal Mixer Omega 300 machine was still not optimal, with an OEE value of 56%. The pneumatic hose component contributed the highest unplanned downtime. The analysis results showed an MTBF value of 1056 minutes, an MTTR value of 30 minutes, and an MDT value of 99 minutes. Improvement proposals were provided through the development of a One Point Lesson (OPL) and an Autonomous Maintenance checklist.
