Ergonomics Analysis of Luggage Trolley for Airport Using Posture Evaluation Index (PEI) in Virtual Environment Modelling

Abstract

Abstract On the science of ergonomics, pushing trolley activity is the type of pushing tasks. Pushing the trolley activities with a given number of loads on it raises the risk of musculoskeletal disorders and discomfort in the body. This study tried to study a series of movements of pushing trolleys and study the ergonomic aspects that affect the posture of the trolley user using simulation in virtual environments. The study was conducted on five types of trolleys with the differences on size dimensions. The goal of this study is to get the kind of trolley which is ideal the operators. Valuation of the work posture done by evaluate the Posture Evaluation Index (PEI) for each trolley. PEI will integrate the assessment results of Rapid Upper Limb Assessment (RULA), Ovako Working Posture Analysis (OWAS), and the Lower Back Analysis (LBA) from the task analysis toolkits contained in the Jack 6.1 software into a score that can give you the actual condition of a person while using the trolley. The results of this study can be used as consideration in choosing trolleys with types and dimensions that really exists in this world that according to the ergonomic aspects of the Indonesian human body.
