Analisis data menggunakan uji normalitas dan pengujian hipotesis. Penelitian ini dilaksanakan bulan Maret-April 2017. Hasil penelitian ditemukan bahwa, pertama latihan sepaksila individu secara signifikan berpengaruh terhadap kemampuan reservice dengan thitung=4,16>ttabel=3,18. Kedua, latihan sepaksila berpasangan secara signifikan berpengaruh terhadap kemampuan reservice, dengan thitung=4.49>ttabel=3,18. Ketiga, baik latihan sepaksila individu maupun latihan sepaksila berpasangan memiliki pengaruh yang sama terhadap kemampuan reservice dengan thitung=0,4399<ttabel=3,18.

Using ABC analysis, the critical parts within the machines will be sorted out and each of the critical parts will be measured the mean time between failure with comparing the total uptime of the spare part and total breakdown per critical component in that period of time. As the result of the study, can be concluded that water injection pump machine, with 3 month averages will have a breakdown that involving the critical parts. The recommendation is, the management has to pay attention at the inventory level of critical parts so it can be more efficient where is the inventory level is not bigger than usage level considering critical parts have high price above all parts that will make higher inventory cost if the supply is more than usage and lack of inventory will causing major shutdown that will cost company some costly opportunity.Keywords : Reliability, Maintenance.
