Analisa Tingkat Resiko pada Komponen Pembangkit Listrik di Kota Balikpapan Dengan Metode FMEA

Abstract

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 40 mendapatkan jensi perawatan prediktif dan preventif, sedangkan komponen dengan nilai RPN<20 mendapatkan perawatan corrective.
