ANALISA RELIABILITY KOMPONEN PADA SISTEM PEMBANGKIT LISTRIK DI PUSDIKLAT MIGAS CEPU

ABSTRAK

Reliability suatu sistem sangat bergantung pada reliability komponen-komponen yang mendukung bekerjanya sistem tersebut. Reliability komponen pada umumnya dipengaruhi oleh model perawatan pemeliharan juga pada budget dari maintenance cost. Oleh karena itu reliability komponen dan reliability system bisa ditetapkan berdasarkan Condition Based dan atau Time Based Maintenance. Sampai saat ini prediksi reliability komponenperalatan yang menunjang pengolahan minyak terutama pada Unit Pembangkit Listrik di Pusdiklat Migas Cepu belum disusun secara sistematis prediksi yang berupa pemeliharaan hanya dilakukan secara periodik tanpa analisa yang pasti seperti analisa Maintenance Cost Mean Time To Failure MTTF jumlah man-hour dan Maintenance Budget. Padahal fakta tersebut sangat membantu Maintenance Management sehingga dapat dijaga reliability komponen yang mendukung terhadap reliability sistem. Metodologi yang dgunakan adalah dengan menganalisa data perawatan peralatan Genset yang ada selama 2 tahun terakhir 2003-2004. Data perawatan tersebut diubah dalam bentuk rupiahman-hour berdasarkan Mean Time To Failure MTTF dan lama perbaikan. Selanjutnya scheduling dilakukan berdasarkan time based dan condition based untuk digunakan perhitungan total budget tahunan. Dari analisa yang dilakukan maka dapat disimpulkan Operasional Cost dan Reliability bertemu titik optimalnya pada jam ke 289. Hal ini menjelaskan bahwa Time Based Maintenance yang sedang berlangsung 326 jam masih mendekati titik optimal. Usaha perbaikan reliability dilakukan dengan menambahkan komponen Filter. Dengan menambahkan komponen tersebut maka reliability system berubah naik dari 40 menjadi 45 .


ABSTRACT

Reliability is a system which is depend on components reliability that supporting the work of its system. In general component reliability is influenced by maintenance model and also the budget of maintenance cost. So that the component reliability and system reliability can be determined based on Condition Based and or Time Based Maintenance. The The prediction of tool nreliability that supporting oil processing especially at Electrical Generator unit Pusdiklat Migas Cepu Does not compile systematically until now. The prediction which is in the form of maintenance is done periodically without certain analysis such as Maintenace Cost Analysis Mean Time To Failure MTTF. The Amount Of Man-Hour and Maintenance Budget. In reality the above fact can support Maintenance Management so that the component reliability which supporting system reliability can be kept. The method used in this case is by analyzing maintenance dataof genset tools during the last two years 2003-2004. The maintenance data are changed into rupiahman-hour based on Mean Time To Failure MTTFand the time of repair. After that sceduling is done based on time based and condition based which used for total calculation of annual budget. From the analysis which has been done it can be concluded that Operational Cost and Reliability meet their optimum point at the time if 1663. After doing analysis the effort of reliability repair can be done by changing maintenance interval that is changing the lubricant and filter that in the beginning is done every 2 weeks 15 days becomes 12 days. By the maintenance interval changing the system reliability increases from 39.76 into 42.46 .
