ANALISIS BEBAN MENTAL MENGGUNAKAN NASA-TLX PADA OPERATOR PRODUKSI PENGGILINGAN SEMEN

Workload is a job demand when receiving requests for orders or demands that will produce a form and level of performance. The problems that cause mental workload are the addition of working hours (overtime), the social relations of other department employees with poor production operators, the temperature in the production operator's environment which is classified as cold there are employees This study aims to determine the minimum and maximum mental workload and to identify mental workload using the Aeronautics and Space Administration Taks Load Index (Nasa TLX) and the Cardiovascular Load (CVL) method. In this study, subjective measurements were made on employees using the NASA TLX method. Six indicators are compared and scored, then the factors that cause high mental load are analysed using the NASA-TLX and CVL methods. Based on the calculation results using the NASA TLX method, it was obtained that out of 24 employees who experienced mental workload, there were 6 workers who experienced high mental workload and physical workload calculations using the CVL percentage and the results of NASA TLX questionnaire data processing, there were 6 workers who experienced mental workload and quite high physical workload. Indicators that affect the 6 workers include the amount of work experienced by workers, external body factors, and internal body factors by the workers themselves.
