To overcome this problem, improvements were made by implementing value stream mapping, especially the 6 stages developed by Datenbank namely (1) draw current stream mapping, (2) identify waste, (3) develop solutions using line balancing and set-up time, (4) develop a future stream mapping, (5) implement solution and (6) measure the results. By reducing the operator who is used as an assistant, the company can reduce the cycle time by 28 seconds or 23% of the total cycle time and reduce the lead time from 8.0425 days to 6.322 days or 21% of the total lead time. Based on the general conversion fee of Rp 5,177,430,756 every year, it is estimated that the company can reduce conversion costs by Rp 1,190,809,074 per year.
