Abstract

ABSTRAK Pada PT. Pertamina EP Cepu Regional 4 Zona 13 Matindok Field telah mengidentifikasi masalah-masalah yang terjadi khususnya di Unit Generator Nitrogen. Berdasarkan pengamatan di lapangan masalah yang didapatkan yaitu khususnya pada Kompresor Nitrogen yang diakibatkan oleh akumulasi air endapan yang masuk kebagian Compressor Screw.Tindakan atau strategi yang tepat adalah memodifikasi jalur pipa yang sering terakumulasi air, lalu ditambahkan beberapa komponen perpipaan agar air yang berada dalam pipa dapat disalurkan keluar dan tidak masuk ke bagian kompresor screw. Adapun tujuan dilakukannya penelitian yaitu untuk mengetahui sambungan-sambungan pada sistem perpipaan dan menemukan solusi air akibat kondensasi di kompresor N2 yang masuk ke komponen/part kompresor sehingga merusak komponen. Metode yang digunakan untuk menyelesaikan permasalahan tersebut adalah metode Fishbone Diagrams  (Diagram Tulang Ikan). Hasil yang didapatkan dengan metode tersebut adalah penyebab terjadinya kerusakan pada kompresor dry nitrogen disebabkan oleh alat yaitu drainnase pada perpipaan terlalu kecil dan kontruksi pipa yang memungkinkan air dapat masuk langsung ke screw, sedangkan penyebab dari manusia yaitu tidak menguras terlebih dahulu air sebelum kompresor running dan penyebab dari lingkungan yaitu tingkat humidity di lapangan 80%. Sehingga penyelesaian yang didapatkan yaitu membuat desain pipeline agar dapat mengurangi kelebihan air endapan dalam pipa, sehingga kemungkinan air masuk ke bagian kompresor dapat dikurangi.

Abstract

This research aims to increase the reliability and availability of the Nitrogen Air Compressor machine and determine the maintenance schedule for the Nitrogen Air Compressor machine. The method used in this research is the Reliability Availability and Maintainability (RAM) method to determine the level of Reliability Availability and Maintainability on Nitrogen Air Compressor machines to determine more optimal maintenance scheduling. The results of this research showed 4 defects in the Nitrogen Air Compressor units C and D components, namely (1) Filter Dryer (M 580-1) (C) produced a system reliability value of 82.47%, a system maintainability value of 83.00%, and Availability that has been carried out can produce an inherent availability value of 99.67% and an operational availability value of 99.92%. (2) Air Inlet Filter (6.4198.1) (C) produces a system reliability value of 81.31%, a system maintainability value of 83.87%, and Availability that has been carried out can produce an inherent availability value of 99.92% and operational availability value is 99.92%. (3) Oil Filter (6.3464.1) (D) and produces a system reliability value of 81.34%, system maintainability value of 85.49%, and the Availability that has been carried out can produce an inherent availability value of 99.93% and operational availability value is 99.93%. (4) Filter Dryer (M 580-1) (D) produces a system reliability value of 80.%, system maintainability value of 85.49%, and Availability that has been carried out can produce an inherent availability value of 99.93% and an operational availability of 99.93%. From these results it can be concluded that the RAM method can determine more optimal machine maintenance scheduling. Suggestions for companies are that they can implement scheduling using the RAM method.
