Abstract

Manual Material Handling (MMH) is an activity which involves a significant amount of load perform by human such as lifting, loading, pushing and pulling. Improper ways of handling this activity such as wrong transfer method and position together with low level of awareness of MMH in workplace, especially in manufacturing sector can contribute to an exposure of risk factors, resulting workers to suffer from a disease called Musculoskeletal Disorders (MSDs). There are three objectives of this research, which are to study the risk factor contributing to the muscle discomfort during performing manual load carrying, to analyze the relationship between Rapid Upper Limb Assessment (RULA) with Revised NIOSH Lifting Equation and lastly to determine the effects of anthropometry with different range of table height. Related information were gathered through a set of questionnaire and certain risk factor had been identified. A significant relationship between Recommended Weight Limit and RULA analysis was determined and as a result, the best range of table height was from 65 cm to 80 cm. Anthropometry will effect certain table height due to awkward posture identified through RULA analysis. The choice for the best table height based on previous result, was narrowed down by implementing the man height as the variable. In the end, the best table range of 75 cm to 80 cm were identified as the most suitable for man height of 155 cm to 180 cm since it can fit wider range of human height.
