Abstract
Kegagalan elemen Produced water treatment system dapat meningkatkan biaya operasi dan berpotensi menyebabkan pencemaran lingkungan Sehingga diperlukan strategi pemeliharaan yang efektif dan efisien. Dalam tugas akhir ini bertujuan untuk menganalisis RAM(Reliability, Availability, and Maintainability), menentukan tindakan pemeliharaan yang sesuai dengan pendekatan RCM(Reliability Centered Maintennace), serta mendapatkan biaya pemeliharaan yang optimal menggunakan metode Non-dominated Sorting Genetic Algorithm (NSGA) II. Hasil dari penelitian menunjukkan bahwa reliability sistem mencapai penurunan 50% dalam waktu 2300 jam. Dalam satu periode preventive maintenance semua komponen produced water treatment memiliki nilai availability di atas 98%. Sedangkan untuk mencapai maintainability 100% waktu perbaikan yang dibutuhkan paling cepat yaitu 4 jam. Jenis Proactive maintenance schedule on condition dan restoration task adalah tindakan yang sesuai untuk diterapkan. Hasil optimisasi didapatkan biaya pemeliharaan yang optimal pada produced water treatment system dalam rentang 5 tahun sebesar USD 18.948.

The failure of the element Produced water treatment system can increase operating costs and potentially cause environmental pollution. Therefore an effective and efficient maintenance strategy is needed. The aims of this thesis to analyze RAM (Reliability, Availability, and Maintainability), determine maintenance actions in accordance using RCM (Reliability Centered Maintenance) approach, and obtain optimal maintenance costs using the Non-dominated Sorting Genetic Algorithm (NSGA) II method. The results of this thesis show that the reliability of the system reaches a 50% reduction within 2300 hours. In one preventive maintenance period all components of produced water treatment have an availability value above 98%. Whereas to achieve 100% maintainability, the fastest repair time is 4 hours. Types of Proactive maintenance schedules on condition and restoration tasks are appropriate actions to be applied. Optimization results obtained optimal maintenance costs in the produced water treatment system within 5 years is USD 18.948.
