Abstract
PLTU Paiton Unit 3 merupakan perusahaan yang bergerak di bidang produksi listrik menggunakan bahan baku batubara yang terletak di Paiton, Probolinggo. Untuk mencapai target proses produksi dilakukan 24 jam selama 1 tahun tanpa henti. Program pemeliharaan mesin sangat penting untuk kelancaran proses produksi. Dalam rangka mencapai target tersebut dituntut adanya kelancaran pengiriman batubara dari silo hingga mencapai surface burner menggunakan pulverizer. Data dari Departemen Engineering menunjukkan bahwa beberapa subsistem pulverizer sering mengalami kerusakan yang dapat menimbulkan kegagalan pada sistem tersebut.
Pada penelitian tugas akhir ini menggunakan metode Reliability Centered Maintenance (RCM) untuk menurunkan tingkat breakdown mesin dan downtime produksi. Data historis kerusakan pulverizer akan dianalisa. Kemudian kegagalan dari suatu komponen yang dapat menyebabkan kegagalan fungsi dari sistem diidentifikasi menggunakan tahap Failure Mode and Effect Analysis (FMEA). Selanjutnya tahap RCM Decision Worksheet untuk mengetahui bagian mana dari sistem yang gagal dan perlu dilakukan tindakan perbaikan dan pencegahan berdasarkan kegagalan yang ada agar kejadian yang sama tidak terulang serta menentukan kegiatan perancang perawatan yang tepat pada setiap komponen.
Berdasarkan analisis data secara Reliability Centered Maintenance (RCM) terdapat 12 failure mode yang terjadi pada pulverizer, 3 failure mode dapat dicegah dengan scheduled restoration task, 8 failure mode dapat dicegah dengan scheduled discard task, dan 1 failure mode dapat dicegah dengan redesign. Analisis distribusi kegagalan dengan perangkat lunak Weibull++6 didapatkan MTBF grinding roller 2880,66 jam, MTBF hydraulic pump 5075,06 jam, MTBF gearbox 5381,65 jam dan MTBF coal feeder 525,17 jam.
=========================================================================================
PLTU Paiton Unit 3 is a company engaged in the production of electricity using coal raw material located in Paiton, Probolinggo. To reach the target production everyday, the process is done 24 hours for 1 year without stopping. Maintenance program is essential for a smooth production process. In order to achieve these targets demanded their fluency delivery of coal from the silo to reach the burner surface using a pulverizer. Data from the Department of Engineering showed that some subsystems pulverizer often damaged which can lead to failure in the system.
In this research using Reliability Centered Maintenance (RCM) to reduce the level of engine breakdown and production downtime. Historical data of pulverizer will be analyzed. Then the failure of a component which may cause a malfunction of the system are identified using phase Failure Mode and Effect Analysis (FMEA). The next stage of RCM Decision Worksheet to determine which parts of the system that failed and the necessary corrective and preventive action based on the failure of which is that the same events are not repeated and to determine appropriate maintanance designer activity on each component.
The result of this thesis shows based on data analysis Reliability Centered Maintenance (RCM) there are 12 failure modes that occur in the pulverizer, 3 failure mode can be prevented with the scheduled restoration task, 8 failure mode can be prevented with a scheduled discard task, and one failure mode can be prevented with the redesign. Failure distribution analysis software obtained Weibull ++ 6 hours MTBF grinding roller 2880.66, 5075.06 hours MTBF hydraulic pump, gearbox 5381.65 hours MTBF and MTBF coal feeder 525.1769 hours.
