PT PAL Indonesia is one of the largest manufacturing companies in Indonesia that operates in the heavy industry sector with shipbuilding as its main product. PT. PAL Indonesia itself has an area of about 120 hectares which is divisionally grouped as Commercial Ship, Warship, Maintenance and Repair, and General Engineering production facilities. Currently, PT. PAL Indonesia has a composition of 1,300 permanent employees, 5,000 contract workers and 2,000 subcontractor workers. In their activities to move from one place of origin to the destination in the construction area, especially the subcontractor workers usually walk, and there are also those who use the worker transport trucks provided by PT. PAL Indonesia and this is because the subcontractor workers can only use these two ways because the subcontractor workers are not allowed to use their private vehicles in the construction area. The fleet of worker transport trucks is limited to only 2 fleets. This makes the subcontractor workers feel lazy when they want to get on the bus because the bus is often full. Good public transportation must have comfort and safety criteria. The worker transport truck currently uses a type of vehicle body that is partially open, so that passengers cannot be fully protected from motor vehicle exhaust and rain. Therefore, the author designed the exterior interior design of a microbus vehicle in the construction area of PT. PAL Indonesia which can carry more passengers and increase comfort and safety factors.
