Abstract
ABSTRAK CV Anugrah Jaya Sejahtera sebuah perusahaan yang bergerak dalam industri manufaktur plate working process (PWP), mempunyai beberapa mesin yang sangat penting bagi jalannya proses produksi yakni seperti mesin shear, press,sekrap, welding, gerinda, bubut. Mesin cutting yang terdapat diperusahaan ada tiga jenis ,ketiga mesin tersebut adalah mesin cutting Hydraulic Shear H- 3065 (1 mesin), Hydraulic Shear H-3013 (1 mesin), Hydraulic Shear H-2565 (1 mesin). Berdasarkan kerusakan periode Januari – Desember 2019 banyak terjadi pada mesin steel work hydraulic shear H-2565 (72 kerusakan dengan total downtime 150 jam). Hasil diagram pareto menunjukan bahwa mesin Hydraulic Shear H-2565 merupakan mesin yang paling kritis yaitu terhadap komponen lubrication pump. Berdasarkan hasil perhitungan Risk Priority Number (RPN) diperoleh bahwa nilai RPN tertinggi adalah 504 RPN oleh sebab itu, perlu adanya perhatian khusus pada komponen lubrication pump tersebut.Masalah ini diselesaikan dengan menerapkan metode Reliability Centered Maintenance II (RCM II) tujuannya adalah dalam rangka untuk menentukan prioritas perbaikan sehingga diperoleh nilai kehandalan terhadap perencanaan waktu penggantian komponen dan minium cost perawatan. Hasil penelitian menunjukan terhadap penerapan Reliability Centered Maintenance II dengan mengaplikasikan LTA, FMEA dan reliabilility concept diperoleh waktu penggantian terhadap komponen kritis lubrication pump selama 252 jam dengan perolehan biaya ekonomis Rp. 308.724.698,00 dengan biaya awal sebesar Rp. 364.196.400,00 maka diperoleh penghematan biaya perawatan penggantian komponen lubrication pump sebesar Rp. 56.071.702,00. Kata Kunci: Maintenance, Reliability, RCM II, dan LTA-FMEA. ABSTRACT CV Anugrah Jaya Sejahtera is a company in manufacturing industry for plate working process (PWP), it has some important machines for production process, such as: shear, press, scrap, welding, grinding, and lathe machine. The company has three types of cutting machines. They are cutting Hydraulic Shear H- 3065 (1 machine), Hydraulic Shear H-3013 (1machine), Hydraulic Shear H-2565 (1 machine). Based on the damage period of January – December 2019 mostly occurred on steel work hydraulic shear machine H-2565 (72 damages with 150 hours total downtime). On Pareto Diagram shows that Hydraulic Shear machine H-2565 is the most critical machine toward lubrication pump component. Based on Risk Priority Number (RPN) calculation, it is obtained that the highest RPN value is 504 RPN, thus, it needs special attention lubrication pump component. The problem is resolved by applying Reliability Centered Maintenance II method (RCM II), the purpose is to determine repairmen priority, so that, it was obtained reliability values on component replacement time schedule and minimum cost maintenance. Research result shows that applying Reliability Centered Maintenance II by implementing LTA, FMEA and reliability concept, it was obtained replacement time on critical component of lubrication pump for 252 hours with economical cost as much as Rp 308.724.698,00 with initial cost Rp 364.196.400,00, then the maintenance cost saving of the lubrication pump component is as much as Rp 56.071.702,00. Keywords: Maintenance, Reliability, RCM II, and LTA-FMEA.
