Mental workload analysis using NASA-TASK LOAD INDEX on manual napkin tissue machine in PT. XYZ

PT XYZ has packer workers tasked with packing tissue on the production floor. In their work, problems often arise related to employees' mental workloads, such as overtime due to irregular working hours, work stress, boredom, accumulation of work, and others. This paper aims to determine the value of mental workload in PT XYZ packer workers and identify factors that cause mental workload so that recommendations for improvement can be given. The subjects of this study were four packers. Data processing was carried out using the NASA - Task Load Index (TLX) method, which has six aspects, namely Mental Demand (MD), Physical Demand 9PD), Temporal Demand (TD), Own Performance (OP), Effort (EF), and Frustration (FR). The results showed that two packers had mental workload scores in the high category above 80, with the highest value of 83,6. So that recommendations can be given for improvements to the work environment and company managerial.
