Abstract
Pembangkit Listrik Tenaga Gas Uap (PLTGU) Gresik dengan total kapasitas produksi listrik sebesar 3x500 MW. PLTGU Gresik unit 1 sampai dengan unit 3 memiliki hidrogen plant yang merupakan salah satu komponen penunjang yang sangat penting. Gas hidrogen yang dihasilkan electrolyzer melalui proses elektrolisis ini dimanfaatkan untuk proses pembangkitan listrik. Kegagalan pada electrolyzer dapat menyebabkan gangguan serius dalam proses produksi hidrogen dan mengakibatkan penurunan output produksi sehingga manajemen keandalan diperlukan untuk memastikan bahwa sistem atau peralatan beroperasi secara optimal. SERP adalah metode untuk memeringkat keandalan sistem peralatan berdasarkan potensi dampak kegagalan. Hasil dari proses SERP adalah Maintenance Priority Index (MPI) berupa pemeringkatan peralatan di hidrogen plant untuk menentukan prioritas pemeliharaan. Parameter distribusi kegagalan digunakan untuk menentukan strategi pemeliharaan yang tepat agar efisiensi kinerja produksi hidrogen meningkat. Hasil penelitian menunjukkan cell stack (A) dan cell stack (B) berada diurutan pertama dengan nilai MPI 511,7 sehingga harus mendapat prioritas lebih utama dalam manajemen pemeliharaan. Preventive maintenance perlu dilakukan untuk mencapai target keandalan 60% untuk peralatan cell stack (A) setiap 500 jam operasi, cell stack (B) setiap 500 jam operasi, storage tank (high press) setiap 800 jam operasi, dan control & electrical panel (B) setiap 325 jam operasi.

Gresik Steam Gas Power Plant (PLTGU) with a total electricity production capacity of 3x500 MW. PLTGU Gresik unit 1 to unit 3 has a hydrogen plant which is one of the most important supporting components. Hydrogen gas produced by the electrolyzer through the electrolysis process is utilized for the electricity generation process. Failure of the electrolyzer can cause serious disruption in the hydrogen production process and result in a decrease in production output so reliability management is needed to ensure that the system or equipment operates optimally. SERP is a method to rank the reliability of equipment systems based on the potential impact of failure. The result of the SERP process is the Maintenance Priority Index (MPI) in the form of ranking equipment in the hydrogen plant to determine maintenance priorities. Failure distribution parameters are used to determine the right maintenance strategy to increase the efficiency of hydrogen production performance. The results showed that cell stack (A) and cell stack (B) are in the first place with an MPI value of 511.7 so that they must be prioritized in maintenance management. Preventive maintenance needs to be done to achieve the 60% reliability target for cell stack (A) equipment every 500 operating hours, cell stack (B) every 500 operating hours, storage tank (high press) every 800 operating hours, and control & electrical panel (B) every 325 operating hours.
