PT. XYZ merupakan perusahaan yang bergerak dibidang produksi spare part dan aksesoris otomotif khusunya sepeda motor. Permasalahan yang dihadapi perusahaan yaitu sering terjadinya kerusakan pada mesin CNC Milling A dengan jumlah kerusakan 32 kali selama tahun 2017 hingga 2018. Perusahaan menerapkan kegiatan preventive maintenance dan corrective maintenance namun kegiatan maintenance ini tidak berjalan dengan optimal. Oleh karena itu, dilakukan pengembangan sistem pemeliharaan untuk meningkatkan keandalan mesin. Metode yang digunakan yaitu Reliability Centered Maintenance (RCM) dengan tujuan menentukan interval waktu pemeliharaan dan estimasi biaya pemeliharaan yang efisien. RCM dilakukan dengan menganalisis kegagalan dengan analisis FMECA. Hasil dari analisis ini berupa nilai RPN yang menunjukkan komponen bearing rel, bearing spindle dan selang sebagai komponen kritis pada sistem. Kemudian ditentukan kebijakan maintenance dengan hasil 2 scheduled on-condition task, 2 scheduled restoration dan 2 scheduled discard task dengan interval waktu maintenance sesuai dengan kategori task. Melalui metode RCM, PT.XYZ dapat menghemat biaya pemeliharaan sebesar Rp. 51.800.331Unduhan
