These activities are conducted as the periodic maintenance schedule. The maintenance standard is also set to ensure that the maintenance activities will be performed well. After the preventive maintenance was implemented by used 5 machines that differently, the result shows that the mean time between failure (MTBF) by average can increases from 176.10 hours/time to 265.88 hours/time so increases by 89.77 hours/time for the mean time to repair (MTTR) by average can decreases from 36.44 hours/time to 21.86 hours/time so decreases by 14.58 hours/time and last for machine availability (A) by average can increases from 81.87 % to 91.51 % so increases by 9.64 %.
