Abstract
Salah satu alat ukur untuk mengetahui kinerja suatu sistem adalah sisa umur. Taksiran sisa umur suatu sistem dapat ditentukan dengan menghitung fungsi Mean Residual Life (MRL). Sisa umur digunakan sebagai salah satu pertimbangan untuk melakukan perawatan dan pemeliharaan sehingga dapat meningkatkan efisiensi proses produksi. Mesin yang terhubung secara paralel sangat penting untuk menunjang proses produksi karena kegagalan semua komponen yang terhubung paralel menyebabkan kegagalan sistem. Tujuan dari penelitian ini adalah menentukan fungsi reliabilitas sistem dan mengestimasi umur dan sisa umur pompa air pada model jaringan paralel dengan melakukan estimasi parameter distribusi kerusakan yang sesuai terlebih dahulu. Simulasi dilakukan pada dua jenis sistem paralel, yaitu sistem paralel pompa air baku yang terdistribusi Weibull dan sistem redundansi cold standby pompa distribusi yang terdistribusi Eksponensial. Simulasi dilakukan dengan menggunakan nilai estimasi parameter yang diperoleh dengan metode MLE dan Bayes, yaitu λ=0,01469, β=2,3418 dan θ=70,6732. Hasil yang diperoleh dari simulasi penelitian ini adalah sistem paralel pompa air baku mempunyai reliabitas sebesar 85,86% dengan estimasi umur 87 hari dan sisa umur 31 hari sedangkan sistem redundansi standby pompa distribusi mempunyai reliabilitas sebesar 54,19% dengan estimasi umur 85 hari dan sisa umur 55 hari.
=============================================================================== One of the measuring tools to know the performance of a system is the residual lifetime. The estimated residual life of a system can be determined by calculating the Mean Residual Life (MRL) function. The residual life is used as a consideration for maintenance so as to improve the efficiency of the production process because machines, which connected in parallel, are essential to support the production process. Failure of all parallel connected components causes system failure. The purposes of this research are to determine the reliability function of the system and to estimate the lifetime and the residual life of the water pump on the parallel network model by estimating the distribution parameters first. The simulation is performed on two types of parallel systems, the parallel system of the raw water pump which is distributed Weibull and the distribution pump standby-redundancy system, which is distributed Eksponensial. Simulation is done by using parameter estimation value obtained by MLE and Bayes method, λ=0,01469, β=2,3418 and θ=70,6732 . The results obtained from the simulation of this research is a parallel system of raw water pump has a reliability of 85,86% with an estimated lifetime of 87 days and the residual of 31 days while standby-redundancy system of the distribution pump has a reliability of 54,19% with an estimated lifetime of 85 days and the residual life of 55 days.
