Abstract
The activity of loading and unloading rice in Indonesia is still carried out using human power. Porters transport rice manually from truck to warehouse or the otherwise. Manual material handling work (MMH) will pose a risk of musculoskeletal disorders (MSDs). The application of the work analysis method generates an analysis per one body position only. There is a need for a model that can perform a work analysis quickly for any change in body movement if it is carried out in dynamic work, for instances on rice porters. In this research, Digital Human Modeling Tecnomatix Jack is used in the Task Simulation Builder menu to simulate dynamic work and generate analysis. The dynamic work carried out is to compare the risk of transporting rice weighing 10 kg and 25 kg. The results obtained are Ergonomic Report, Static Strength Prediction (SSP), Low Back Compression Analysis (LBA), Fatigue, Cumulative Loading and Metabolic Energy Expenditure (MEE). The simulator also provides the SSV file extension as in SSP. If needed, this result can be entered in a formula according to work analysis method such as RULA or REBA so that every change in movement obtained results related to the risk that may occur.
