Abstract

Dalam penelitian tugas akhir ini dilakukan implementasi Reliability Centered Maintenance (RCM) pada sistem methanator yang berfungsi untuk mengkonversi CO dan CO2 sisa proses CO shift conversion dan CO2 removal ke dalam bentuk Metana (CH4), sebelum memasuki proses sintesis amoniak. Analisis kualitatif pada masing-masing komponen/unit penyusun sistem methanator adalah berupa penjelasan fungsi (system function) yang diikuti dengan hasil pengolahan data yang disajikan dalam tabel FMEA dan tabel decision worksheet. Analisis kuantitatif pada masingmasing komponen/unit penyusun sistem methanator didasarkan atas hasil perhitungan keandalan (reliability), ketersediaan (availability), keterawatan (maintainability), serta hubungan antara laju kegagalan (failure rate) terhadap langkah preventive maintenance yang diimplementasikan terhadap masing-masing komponen/unit. Berdasarkan hasil penelitian, diketahui bahwa komponen kritis berdasarkan nilai keandalannya yang sudah mencapai 0,6 saat sebelum 1000 jam operasi adalah unit-unit besar itu sendiri, yaitu Exchanger 114-C, Methanator 106-D, dan Cooler 115-C. Pada akhirnya, dari 7 unit/komponen yang ada, didapatkan 1 komponen dengan scheduled restoration task, 2 komponen dengan scheduled on-condition task, dan 4 komponen dengan no scheduled maintenance, berdasarkan hasil implementasi preventive maintenance. ===================================================================================================== In this final project there is an implementation of Reliability Centered Maintenance (RCM) on methanator system which has main function in converting CO and CO2 from CO shift conversion and CO2 removal system to Methane (CH4) form, before entering synthesis of ammonia process. Qualitative analysis in each components of methanator system is about explanation of system function that is following with the result of data processing which is written as FMEA table and decision worksheet table. Quantitative analysis in each components of methanator system is based on measurement of reliability, availability, maintainability, and the relationship between failure rate and preventive maintenance that is implemented to each components. From the result, we know that critical components based on its reliability of 0,6 before 1000 operation hours are the main components, such as Exchanger 114-C, Methanator 106-D, and Cooler 115-C. Finally, from all the 7 components, we got 1 component with scheduled restoration task, 2 components with scheduled on-condition task, and 4 components with no scheduled maintenance, based on the implementation of preventive maintenance.
