NASA-TLX Assessment of Mental Workload in Manufacturing Industry

Mental workload assessment is essential for the optimal interaction of human system in manufacturing industry. Manufacturing industry engaged construction, maintenance, and fabrication service. Performance worker will be lower if higher workload. In are two type workers that mainly involved process such as operator welder. This was found several defects finished good which caused company to suffer losses. Fatigue due overtime work seven days a high mental The aim this study measure performed on 10 were assessed using NASA Task Load Index (NASA-TLX) Fault Tree Analysis (FTA) tools. One one welders belonged heavy category. Finally, NASA-TLX significantly High indicated defection It recommended fixes evaluating updating rule work, existing SOP
