Improvement of Work System and Physical Work Environment to Increase Worker Productivity in Natural Tofu Factory
Abstract
Ergonomics is a scientific discipline that studies the capabilities and limitations of humans, as well as interactions between humans and other system elements (such as machines, workplaces and work environments) in order to create an optimal work system. Ergonomics should be applied to work systems or industries that are generally done by humans manually. One of the industries that is done manually is the business of making tofu at the Natural Tofu Factory. The postures analyzed were the soybean extraction process, the screening process, the printing process and the cutting process. From the assessment of work posture, there are several work postures that are classified at the level of moderate risk in the sense that changes may be needed to improve work attitudes. Work posture that is classified as a high risk level which means it is very dangerous to the musculoskeletal system, needs improvement now. It is influenced by unnatural posture (bent over, neck bent, arms away from the body), repetitive activities, muscle use and excessive exertion.
