Production Line Arrangement to Increase Output in order to Meet PT. DMR's Delivery Time in Surabaya

Abstract

PT DMR is a job order that produces ± 285 product items. This study focuses on 3 items, namely Wheels (wheels 30, 40, and 50), Hinge T 86, and Handle 28. Currently, the company has not been able to determine the capacity of each production line and has not been able to determine the Delivery Time accurately. The company wants to know and increase its production capacity so that it can be determined when the Delivery Time is on time. The analysis method used is the arrangement of the production line with line balance. After the calculation and analysis, it was obtained that the efficiency of the Wheel 40 product line increased from 52.43% to 78.19%, Balance Delay decreased from 47.57% to 21.87%, while the Cycle Time of production operations decreased from 15.84 "to 9.00", this occurred due to the use of expanded mattress holes from 10 holes to 14 holes. Wheel 50 experienced an increase in track efficiency from 48.83% to 95.31%, with a decrease in Balance Delay from 51.17 to 4.69, while for the Cycle Time of operations decreased from 19.52 "to 10.00", this occurred due to the use of expanded mattress holes from 8 holes to 12 mattress holes. Hinge T 86 increased from 46.40% to 50.3%, with balance delay decreased from 53.60% to 49.7%, while the operating Cycle Time decreased from 28.8” to 26.58”, an increase due to the addition of outsourcing capacity from 6000 pieces / 2 days to 7000 pieces / 2 days, namely by adding other sources, or still with the condition of additional outsourcing capacity. Handle 28 was not changed because the calculation results showed a production line efficiency of 93.3% (quite high) and Balance Delay 6.7%.
