PT Dirgantara Indonesia (PT DI) is a state-owned company (BUMN) which runs an aeronautics business that produces airplanes and helicopters. Helicopter MK-II is one of its products with high production targets, especially the tailboom part. Tailboom is a helicopter’s tail that will be assembled with fuselage or helicopter body to form a complete helicopter. Tailboom Helicopter MK-II has 15 unit production targets per year. But PT DI only could produce 13 units per year. For each target difference that is not reached, it will be added up to the next year’s target, and in 2019 the target is 22 unit tailboom. In the production process, pylon, cone, and junction sub-assembly took the longest time among the other process. It because of the lack of mechanic in those parts. Thus, the line production couldn’t run optimally, and the production target couldn’t be reached. The integer linear programming for multioperator assembly line balancing with the objective to minimize the cycle time and the worker is used to solve this problem. The computation results that pylon couldn’t meet the takt time. Therefore, two alternative solutions generated. The first one is adding four mechanics with overtime ten days for each pylon component production, while the second one is adding eight mechanics and change the sequence of the production process for pylon. The best solution is adding eight mechanics and change the sequence of the production process for pylon. This solution can improve production capacity until 26 units per year, therefore the company can generate profit to six hundred million rupiahs per year.
