Analysis of the Workload Measurement Using Cardiovascular Load (CVL) and NASA Task Load Index (NASA-TLX) in XYZ Inc.

XYZ Inc. is an industrial company engaged in the processing of palm oil and its derivatives. With excessive working hours and shift pattern change of once a week, unachieved production targets, work accidents occurrence, and employees who ask for permission or absent because of illness, it can cause workload both physically and mentally at the production department. This study was conducted to analyze the workload using the Cardiovascular Load (CVL) and NASA-TLX methods. The calculation results using the CVL method showed that the greatest physical workload in the shift I and shift II was perceived by KALI from the refra 3 station of group C with the CVL value of 36.73% and 32.38% with notes that improvement was needed. The results using the NASA-TLX method showed very high mental workload in ABD in the shift I of group B of 84.67%, ALI in the shift I of group C of 86.67%, AG in the shift I group C of 85.33 %, ALI in shift II of group C of 81.33% and AG in the shift II of group C of 85.33%. Based on the Cardiovascular Load (CVL) and NASA-TLX results, 9 employees experienced physical workloads and 5 employees experienced mental workloads.
