Abstract

The purpose of this project is to analyze working posture in of operator in mixing department in an SMIs (Small Medium Industry) in Malaysia. From previous study, it is found that back pain and CTDs (Cumulative Trauma Disorders) are the types of injury occurred associated to working postures. This project is done to identify the risk factors for lifting activity in the manufacturing industry. Furthermore, the research is focus on analyzing the working postures of the mixing department operators using RULA and REBA methods. Other than that, the 1991 NIOSH lifting equation is used to find the (RWL) recommended work limit of the current workstations. RULA analysis is done using CATIA software while REBA analysis is done using the REBA Employee Assessment Worksheet. In order to do the analysis, the anthropometry data, image and video recording of the activity are taken. The data are used to do the RULA and REBA analysis. In this project, the company that accepted the research is an SMI factory located in Kuala Selangor. This factory produces plastic based product, rain gutter system and pipes. Mixer department is one of the production sections in this company. In this department, the raw materials in powder are mixed in order to be processed using the extruder machines. In this section, the workers have to lift load 25kg everyday. The activity that analyzed is the process of transferring the sacks of resin to the funnel. The activity is divided into four sub processes to in order to determine which activity is the worse. Based on the analysis of the project, the result of the research recommended improvements of the workstation. This improvement intended to decrease the risk of injury of the workers.
