Work Mental Load Analysis on Car Repair Mechanics in Yogyakarta

Abstract

Mechanics must work with precision, excellent and consistent speed, and other work that drains both the mechanic’s physical and mental energy. Official motorbike mechanics experience complaints of work stress due to high work demands. Regarding the measurement of mental workload, a subjective workload is easily given and has a high assessment ability because the measurement is not dependent on the task. The NASA-TLX (Task Load Index) scale is the most widely used subjective scale by asking participants to rank separately on the subscale of mental demand, physical demand, temporal demand, performance, effort, and frustration level. This will be useful to be able to distinguish between tasks in terms of the specific subscale. Mental demand has the highest result (305) because the car workshop is demanded to find the cause of damage to the car, then remember the car components when dismantled and re-installed. Based on statistical analysis, between mental demand and working hours indicates a positive relationship. Heavy mental activities can be reduced by training workshop workers relating to administration, expertise in each type of car, and comfortable and safe work areas.
