Abstract

Manufacturing industry sector is one of industrializing parties that gives significant contribution in achieving the vision of 2020. The ability of human workers is compulsory in letting the industry to be successful in producing products. Unfortunately, many of painful afflictions of musculoskeletal system, known as Cumulative Trauma Disorder (CTD), are associated with the working postures. In additional with, improper design of a workstation would make the task more difficult, strenuous, fatiguing, boring, and uncomfortable. This thesis is addressing three objectives which are projected in a chosen manufacturing company. Basically, these thesis objectives are to identify the response of workers, to analyze working postures at the current workstation and redesign together with analyzing the effectiveness. PRYM CONSUMER (M) has accepted this research and agreed that this case study conducted in PRYM CONSUMER (M) Company. Two major sections of the company have been investigated. The method to identify response is by questionnaires that distributed among the workers. To analyze working posture at the current workstation is done by assessing it by RULA method. The redesigning occurs when it is needed and the effectiveness of the proposed designs is analyzed by comparing before and after results. The results of these thesis is divided into three main sections which is the response of workers is identified that the workers are alert of the pain of their body part. Most workers are exposed to the upper limb discomfort which is contributed to the over reaching and awkward postures. The RULA score from current workstation design has shown that the workers postures are exposed to many ergonomic risks. The redesigns of workstation show several improvements on the working postures that is resulting lower RULA score in the final score. The effectiveness of the redesign has been proved by many of the RULA score is basically lowered and all the working posture involved is well analyzed and a total improvements are addressed. Conclusively, through questionnaires, basic response and a rough explanation on the working conditions is understood. The current working postures and redesign of workstation analysis is sufficient to detect the problem that occurs in the workstation.
