Company X is a power plant that supplies Balikpapan city electricity. In order to maintain the availability of electricity, regular maintenance is carried out, predictive, preventive and corrective maintenance in company X. The maintenance scheme of each component is based on the level of risk and priority scale. In this study, the determination of the level of risk and priority scale for each component uses Failure Mode And Effect Analysis (FMEA). The subject of the research was the W20V320 engine type diesel fuel component in the X power plant in Balikpapan City. Maintenance data for 2 years, 2017 and 2018, with 420 failure modes from 67 components used as research data. Engines are grouped into 12 systems and each system has a RPN (Risk Priority Number) value. In the RPN the Severity, Occurance, and Detection values are arranged based on company X's condition at the time the report is written. The highest RPN value is found in the Radiator Motor Fan component in the Radiator system and the LO Separator component in the Lube Oil Supply System  which is 144. Components with an RPN value> 40 receive predictive and preventive maintenance services, while components with an RPN value <20 get corrective maentenance services. Keywords : FMEA Maintenance, RPNABSTRAKPerusahaan X merupakan pembangkit yang memasok listrik kota Balikpapan. Demi menjaga ketersedian listrik dilakukan perawatan secara berkala yaitu predictive, preventive dan corrective maintenance pada perusahaan X. Skema perawatan setiap komponen berdasarkan tingkat resiko dan skala prioritas. Pada penelitian dilakukan penentuan tingkat resiko dan skala prioritas setiap komponen menggunakan Failure Mode And Effect Analysis (FMEA). Subjek penelitian adalah komponen Engine tipe W20V320 berbahan bakar solar pada pembangkit listrik X di Kota Balikpapan. Data perawatan selama 2 tahun yaitu tahun 2017 dan 2018, dengan 420 mode kegagalan dari 67 komponen digunakan sebagai data penelitian. Engine dikelompokkan menjadi 12 sistem dan setiap sistem memiliki nilai RPN (Risk Priority Number). Pada RPN nilai Severity, Occurance, dan  Detection disusun berdasarkan kondisi perusahaan X saat laporan ditulis. Nilai RPN  tertinggi terdapat pada komponen Radiator Motor Fan di sistem Radiator dan Komponen LO Separator di sistem Lube Oil Supply System yaitu 144. Komponen dengan nilai RPN>40 mendapatkan jensi perawatan prediktif dan preventif, sedangkan komponen dengan nilai RPN<20 mendapatkan perawatan corrective.Kata kunci :  FMEA, Maintenance, RPN
