To continuously adapt to the Industry 4.0 era, PT Toyota Motor Manufacturing Indonesia, a company operating in the automotive industry, prioritizes the adoption of smart offices through the digitalization of various business processes, including human resource development via the Toyota Learning Center (TLC). Currently, TLC has implemented several digitalization initiatives that have successfully enhanced the efficiency of human resource training, one of which is the use of virtual reality training for welding and safety induction tasks. Given the advantages of VR in these training areas, TLC aims to expand the virtual training modules to cover assembly tasks, with the objective of sustainably minimizing waste and operational costs. However, the management is yet to understand the impact of VR-based assembly training on workers' cognitive abilities. Therefore, this study aims to evaluate the implementation of VR-based assembly training on the cognitive skills of assembly workers. This research was conducted using a between-subjects experiment on two independent groups that received assembly training through conventional video-based methods and VR. The experiment began with training sessions using different methods for the two groups, followed by an assembly test on a tripod product model. During the testing session, performance parameters were measured by recording the duration of assembly completion. Furthermore, mental workload parameters were assessed using the NASA TLX form, working memory was assessed through a post-test form, and the usability of the existing system was evaluated using the SUS form. Finally, the correlation between work performance and working memory parameters was calculated. The results indicate that conventional assembly training significantly leads to better work performance. However, there was no significant difference found between the two groups in terms of mental workload and working memory. Additionally, the existing system used in the study was deemed acceptable by participants. A strong positive linear correlation between work performance and working memory was also found. It is hoped that this study can provide insights that assist the company’s management in considering the implementation of VR-based assembly training.
