Abstract
This research aims to formulate an optimal preventive maintenance strategy for the DC battery backup control system to ensure the operational sustainability of Gas Turbine Compressors in the oil and gas sector. The study is prompted by a unit shutdown in July 2024 caused by the failure of VRLA-type batteries, which sustained the load for less than 5 minutes significantly below the technical specification of 8 to 10 hours. This study employs a mixed-methods approach, integrating qualitative data from interviews and field observations with quantitative data from operational reports and historical analyzer records. Root causes were systematically identified using Fishbone Diagrams and 5-Why analysis. The findings indicate that battery capacity degradation was caused by deviations from original specifications and a significant influence of human factors in maintenance procedures. As a solution, corrective actions involving battery unit replacement and the strengthening of maintenance strategies were implemented. Final testing demonstrated a significant improvement in system reliability, with the batteries successfully supporting the control load stably in accordance with established operational standards. Keywords: DC Battery Back-Up; Gas Turbine Compressor; Battery Capacity Degradation; Preventive Maintenance; Reliability Analysis. Penelitian ini bertujuan untuk merumuskan strategi pemeliharaan preventif yang optimal pada sistem kontrol cadangan baterai DC guna menjamin keberlanjutan operasional Gas Turbine Compressor di sektor minyak dan gas. Studi ini dilatarbelakangi oleh terjadinya unit shutdown pada Juli 2024 akibat kegagalan baterai tipe VRLA yang hanya mampu menopang beban selama kurang dari 5 menit, jauh di bawah spesifikasi teknisnya yang seharusnya mencapai 8 hingga 10 jam. Penelitian ini menggunakan metode campuran (mixed-methods) dengan mengintegrasikan data kualitatif melalui wawancara serta observasi lapangan, dan data kuantitatif dari laporan operasional serta catatan historis alat analisis. Identifikasi akar masalah dilakukan secara sistematis menggunakan Diagram Fishbone dan analisis 5-Why. Hasil kajian menunjukkan bahwa degradasi kapasitas baterai disebabkan oleh deviasi spesifikasi awal serta adanya pengaruh signifikan dari faktor manusia dalam prosedur pemeliharaan. Sebagai solusi, tindakan korektif berupa penggantian unit baterai dan penguatan strategi pemeliharaan telah diimplementasikan. Pengujian akhir membuktikan adanya peningkatan keandalan sistem secara signifikan, di mana baterai kini mampu menopang beban kontrol dengan stabil sesuai dengan standar operasional yang ditetapkan. Kata Kunci: DC Battery Back-Up; Gas Turbine Compressor; Degradasi Kapasitas Baterai; Pemeliharaan Preventif; Analisis Keandalan.
