1 Nazaruddin1 IMPLEMENTASI TOTAL PRODUCTIVITY MAINTENANCE (TPM) Nazaruddin

2 Kebijakan keuangan UGM 2 Ada 2 metode pengukuran produktivitas (Sumanth, 1984): 1. Productivity Management; proses manajemen formal yg menyertakan semua tingkatan manajemen dan kartyawan dengan sasaran akahir mengurangi ongkos pabrikasi, distribusi dan penjualan suatu produk/jasa melalui suatu pengintegrasian empat tahap siklus produktivitas (MEPI) 2. Productivity Engineering; terkait dengan disain, pemeliharaan dan pengembangan pengukuran produktivitas, evaluasi, perencanaan, dan sistem peningkatan dalam organisasi pabrikasi dan jasa

3 Nazaruddin3 Nakajima (1988); productivity engineering ≈ Total Productivity Maintenance melalui pengukuran Overall Equipments Effectiveness (OEE) W. Mark & M. Nakamura (1997); “ TPM is an activity/partnership between maintennace and production organisations to improve product quality, reduce waste, reduce manufacturing cost, increase equipment availability and improve a company’s overall state of maintenance”

Reduced Speed 5. Defects in Process 6. Reduced Yield MTBF Availability = MTBF + MTTR + MWT (Total Pieces/Operating Time) Performance = Efficiency Theoritical O/T Processed amount – Defect amount Rate of Quality = Products Processed amount EquipmentsSix Big Losses Calculation of Overall Equipments Effectiveness OVERALL EQUIPMENTS EFFECTIVENESS = Availability x Performance Eff x Rate of Quality

5 Nazaruddin5 Ket: MTBF : Mean Time Between Failure (expectation of production time between failures) MTTR : Mean Time To Repair (expectation of time to restoration) MWT : Mean Waiting Time (expectation of time for restoration to statr) OVERALL EQUIPMENTS EFFECTIVENESS (OEE) = Availability x Performance x Rate of Quality Avaibility; pengukuran kehandalan mesin yang diukur dari waktu terbuang (downtime loss) pada Saat mesin utama sedang beroperasi, sedangkan Performance Efficiency Mengukur ouput selama waktu yang tersedia (actual cycle time) dibandingkan dengan kapasitas terpasang (theoretical cycle time) dan Quality Rate mengukur tingkat ouput produk bagus dibandingkan dengan jumlah produk gagal
