The development of digitalization in the industrial world is increasingly expanding to all facets of the company. One of the digitalization that is starting to emerge is VR-based training. Various studies show that training with VR can improve operator performance, but there are also those that state that the use of VR increases mental workload. However, these studies are limited to using only subjective measurements to measure mental workload in VR training. Therefore, this study aims to compare mental workload between VR and conventional training methods with physiological and subjective measurements. In addition, this study also assessed the feasibility of using VR as a training media in terms of usability and cost. This study involved 16 students who were divided into two groups of participants, i.e. the group trained using VR and using conventional via video. In this training, assembly was limited to tripod objects. Mental workload was measured using physiological measurements, namely heart rate variability (HRV) and electroencephalography (EEG), as well as subjective assessment using the NASA Task Load Index (NASA-TLX) assessment. Physiological and subjective data were analyzed using statistical tests to determine the average difference between the two training methods. The feasibility of VR as a training media in terms of usability was assessed using the System Usability Scale (SUS) assessment while the cost comparison was carried out by comparing technology and labor costs. Based on physiological and subjective measurements, the two training methods have no significant difference in mental workload. The usability assessment results show that the use of VR is acceptable to participants. In terms of cost, although the initial investment cost of VR training is higher, the annual cost for the next period is much smaller than conventional training.
