【 摘 要 】

This research was conducted on the loading process of manual material handling of cup mineral water activity at PT. PA, Aceh Besar, Indonesia. With samples of 12 transport workers, the observed loading activity includes the position of lifting, walking, and loading. The loading process is done manually from the warehouse into the truck. This work is done continuously by a transport worker with each transported load reaching 48 kilograms. In a one-Time loading process, a transport worker performs as many as 33 trips and the timing for each transport loading process is 20 seconds. With the work done continuously and the loads transported are weighty; therefore there are risks of experiencing musculoskeletal disorders by the transport workers. Thus, questionnaires, interviews, and observations were used as instruments to obtain data. Calculations were further conducted to analyze the postures of transport workers by using the Photogrammetric Method. The results show that the moment force calculation at L5/S1 is greatest in the position of lifting the load at 5.756,81 N; meanwhile, the NIOSH provision is 3,400 N for a normal lift limit. Hence, the solutions proposed to this problem are to reduce the load to 24 kilograms/loading and the utilization of the trolley.
