<![CDATA[This research is shown to analyze the causes of malfunction tester machine at PT WIK Far East Batam. The population in this study is the function tester machine at PT WIK Batam. The technique of taking samples in this research is to use a purposive sampling technique. In this research technique, the machine as the object used as the sample is the function tester machine which has the most problems and has the longest downtime. The data analysis technique uses the failure mode and effect method, the data analysis technique uses FMEA, FTA, MTTF, and repair scheduling reliability, based on the FMEA results, Conveyor is the component that has the highest RPN value, followed by flowmeter, on the damage distribution, the Weibull distribution was chosen because has the highest fit index value, by calculating the MTTF, the results obtained for 11 days before the component is damaged, and through the Reliability calculation, shows the machine reliability value on the machine maintenance schedule of 0.39807]]>
