Abstract

Pembangkit Listrik Tenaga Uap (PLTU) PT Indo Pusaka Berau is a PLN work unit that provides electricity to consumers. The problem of the company is the frequent damage to boiler engine components. The company uses corrective maintenance system. On the problem, it is necessary to develop a machine maintenance system with Reliability Centered Maintenance (RCM) approach. The objective of the study was to select a boiler system maintenance action based on the RCM method and component replacement interval to minimize Total Minimum Downtime (TMD). Results of data processing RCM method, component in category Condition Directed (CD) is El Bow component. Components in Time Directed category (TD) are gland seal steam and check valve. Components in the Time Directed category are calculated for component replacement intervals on TMD criteria. The calculation result from component replacement interval was obtained 37 days for gland seal steam component and 58 days for check valve component. The proposed treatment of RCM method can reduce downtime by 11.33% of the company's maintenance methods.

Abstract

Waste is the residual product from an industrial process and the household, useless, no economic value and is a serious problem in the industrial era 4.0, where regulations on environmentally friendly industrialization are an important issue. Primary industries such as sugar cane, oil palm, cocoa produce a lot of wastes during the pre-harvest period such as leaves and three litters, and in the post-harvest period such as pulp, fruit skins, and fruit pulp. PT Berau Cocoa processes cocoa skin waste into animal feed which is applied to cattle in Binungan. This research uses a descriptive research method and how to teach data by distributing 50 questionnaires to cocoa farmers. The results of data analysis show the fact that most cocoa farmers are male of 38 peoples (76%), high school education level of 33 peoples (82%), joined along 4-6 years as 45 peoples (90 %), all respondents are married, and own private land. Supporting factors that influence the processing of cocoa waste into animal feed can be seen from the average value of each factor, method factor (0.596), material factor (0.512), human factor (0.416), and money factors (0.404), and the lowest average is the engine factor (0.312).
