Abstract

Ergonomic risk is the common issues in manufacturing industry due to the less knowledge of ergonomic and awkward posture during working. Based on the previous study, it shows that awkward posture and heavy lifting were the most highlighted issues that occurs in Aero Composite industry because this industry that normally use manual handling working process. The aim of this study is to analyze the working posture at Aero Composite industry in mechanical assembly and suggest an conceptual design of improvement workstation. Four objective have been constructed based on the problem statement. The first objective that have been done the project use Rapid Upper Limb Assessment (RULA) in order to analyze the most level of risk of workers during working. The method that were used on this first objective are to make an RULA analysis CATIA V5 and DELMIA V5 is used to replicate the workers posture and make an RULA analysis. In this industry one of the highest ergonomic risk occurs at drilling activity. Then, for the second objective on this project is to develop manikin by using Aero Composite Industry population. This manikin industry population can be used to identify the RULA and the suitable activity of workers during working. Besides, this project is to simulate the working process of mechanical assembly to analyze the risk via simulation. This project use DELMIA V5 to simulate the working process at Aero Composite Industry. Therefore, these simulations have been done by globalize simulation for whole department with all process activity while localize is the specific activity that have been chosen based on the highest risk activity occurs in Aero Composite Industry. The last objective is to suggest improvement to the industry to assist this industry to solve the ergonomic issues as well to increase their productivity and quality of life of the workers. This research is expected to create a design guideline for the industry that help workers complete the job safer and more comfortable at the workstation during working.
