ABSTRACT
The working practices involve turning, cutting, scraping, welding, grinding training and so on. Almost all working practices are conducted in standing position. With eight hour session a day, it can be predicted that there will be a lot of disorders, especially the subjective ones such as the musculoskeletal disorders, general fatigue and concentration as well as the workload. In order to be able to compete, hence, the industry has to be able to give the best service to the customers, have a comfortable working atmosphere, interesting and friendly performance of the students, fast service, and the products fulfill the customers’ expectation. Consequently, the eciency and productivity of work must be accelerated optimally in order to reach the above goal. The improvement of the work productivity can be reached by pressing all
kinds of input into the minimum level and increasing output into the maximum one [1]. The input, especially related to resources, has to be employed in an optimal fashion. In order to reach such condition, the students must be facilitated with comfortable, safe, and ecient work facilities. The work facilities comprise of, work station, work environment and work organization that is in accordance with the capability, skill and limitation of students in the hope that the productivity can be reached at the highest level [2]. It is a study of the psychology of the machine workers need to be developed, the evaluation of the influence of the working position before and after work that could potentially result in musculoskeletal disorders, general fatigue, workload and workers’ concentration has been explored, it is becoming a major base for providing information about the parameters important in formulating motion studies on the psychology
of the machine working in a range of complex conditions and broader data.
