A Usability Study of Mobile Augmented Reality-Based Learning Media for Heavy Equipment Safety in Indonesian Vocational School

Mining involves working in hazardous environments with various risks. The most common cause of mining accidents was mechanical failure, involving the use of heavy equipment. Thus, students who learn mining geology in vocational school must increase their knowledge of heavy equipment safety before they can work with it in the actual workplace. However, heavy equipment is very expensive and requires proper inspection and routine maintenance which needs high financial allocation for vocational schools. Thus, technology that can develop heavy equipment safety learning media reasonably affordable, interactive, and safe is needed. With the help of immersive technology, such as augmented reality (AR) will benefit students to attain important knowledge in heavy equipment safety. This study developed a learning module and a mobile AR application as learning media for heavy equipment safety and evaluated its validity and usability.
