Development of Transmission Jack Table as a Learning Innovation of Transmission Overhaul Practice to Reduce the Risk of Cumulative Trauma Disorders (CTDs) in Students

—The purpose of this research is to produce a tool that serves to help hold, lift, and lift and place the transmission to unload. The tool is called a transmission jack table which is designed to reduce the risk of cumulative ergonomic trauma disorders (CTDs) suffered by student practitioners in the transmission overhaul practice of the automotive power train course. This design uses an ergonomics approach, starting with anthropometric measurements of students, designing using software and making prototypes, then testing and analysis using the Quick Exposure Checklist (QEC) method. The result of this study is to obtain a tool in the form of a transmission jack table and reduce the risk of cumulative ergonomic trauma disorders (CTDs) experienced by students. So that this learning tool has a good impact in reducing musculoskeletal complaints and reducing the risk of work accidents and increasing work productivity.
