Afterward, the utilization rate of time and productivity were calculated from the existing standard time and from the calculated standard time. In measurement of work time for preparations of RR Axle Avanza in Trimming 0 activities, Assembly Production Department in Karawang Plant, it was found that the operator had a 71 seconds lack time from 15 activities, while having 202 seconds remaining time from 22 activities. The utilization rate the existing standard time was 73,53% and the productivity was 7,27 units/hour. After the calculation of new standard time, it was obtained that the utilization rate was 87,3% and the productivity was 8,63 unit/hour with 53 seconds unutilized time and no lack time. This shows that the new standard time can be used as a guidance for preparations of RR Axle Avanza activities.
