Optimalisasi Pemeliharaan Dalam Rangka Penurunan Downtime Mesin Carton Erector Fl-01 Di Pt Pertamina Lubricants Production Unit Jakarta

Abstract

Downtime mesin adalah nilai waktu mesin tidak beroperasi yang menyebabkan mesin tidak dapat menjalankan sebagaimana fungsinya. Tujuan dari penelitian ini adalah untuk menurunkan nilai downtime mesin carton erector FL-01 di PT Pertamina Lubricants PUJ (Production Unit Jakarta). Berdasarakan tujuan tersebut dilakukan pengukuran TPM (Total Productive Maintenance) dengan perhitungan OEE (Overall Equipment Effectiveness), Reliability Maintenance, metode FTA (Fault Tree Analysis) dan metode RCM (Reliability Centered Maintenance) sebagai penentuan strategi perawatan. Setelah menerapkan usulan strategi perawatan beserta penggunaan checklist preventive maintenance dan OPL (One Point Lesson), menunjukan tercapainya tujuan penelitian ini. Hasil dari implementasi selama 3 bulan, menunjukan penurunan nilai rata-rata downtime mesin carton erector FL-01 sebesar 5,9% dan peningkatan nilai OEE (Overall Equipment Effectiveness) sebesar 6,8% berdasarkan kenaikan nilai availability rate sebesar 5,9%, performance rate sebesar 1,0%, dan quality rate sebesar 0,2%.

Machine downtime is the value of the time during which the machine is not operating that causes the machine not to be able to run as it should. The purpose of this study was to reduce the downtime value of FL-01 carton erector machine at PT Pertamina Lubricants PUJ (Production Unit Jakarta). In solving this problem, TPM (Total Productive Maintenance) measurements were carried out with OEE (Overall Equipment Effectiveness) calculations, Reliability Maintenance, FTA (Fault Tree Analysis) method, and RCM (Reliability Centered Maintenance) method as the determination of maintenance strategies. After implementing the proposed maintenance strategy along with the use of preventive maintenance checklists and OPL (One Point Lesson), it shows that the objective of this study has been achieved. The results of the implementation for 3 months show decrease in the average downtime value of the FL-01 carton erector machine by 5.9% and an increase in the OEE (Overall Equipment Effectiveness) value by 6.8% based on an increase in the availability rate value of 5.9%, a performance rate of 1.0%, and a quality rate of 0.2%.
