Abstract
The problem that occurs in the practice of transmission overhaul is that every time students practice they always experience complaints of pain in several parts of the body, especially the upper body. The pain causes students to take a lot of short breaks when doing transmission overhaul practices such as straightening their backs, lowering their hands or moving their necks to reduce soreness. Based on a preliminary study by distributing Nordic Body Map (NBM) questionnaires, many students experienced complaints of pain in the upper neck, lower neck, back, waist, right left forearm and left upper right arm. The purpose of this study was to produce a tool that serves to help hold, lower, lift the transmission and place the transmission for unloading and to determine the effect of using this practice tool on reducing ergonomic risk. The tool is called a transmission jack table which is designed to reduce the risk of ergonomic cumulative trauma disorders (CTDs) suffered by student practitioners in the transmission overhaul practice of the automotive power train course. This design uses an ergonomic approach, starting with antropometric measurements of students, designing using software and making prototypes, then testing and analysis using the Quick Exposure Checklist (QEC) method. The results of this study are the acquisition of practical aids in the form of a transmission jack table and a decrease in the risk of ergonomic cumulative trauma disorders (CTDs) suffered by students. So that this learning tool has a good impact in reducing musculoskeletal complaints and the impact will reduce the risk of work accidents and increase work productivity.
