The utilization of an Augmented Reality (AR)-based Virtual Laboratory in chemistry education requires teachers to possess practical skills to ensure that the technology can be used optimally in learning activities. This community service activity aimed to improve chemistry teachers’ practical skills in accessing, operating, and integrating an AR-based Virtual Laboratory into learning. The activity was conducted in collaboration with the Chemistry Teachers’ Association (MGMP) of Pangkep Regency and involved 20 teachers through practice-based training consisting of technology orientation, demonstration, guided practice, independent practice, integration of AR with chemistry content, development of learning activity scenarios, and simulation. The evaluation was conducted through practical skills observations based on six indicators: the ability to access the Virtual Laboratory, operate Virtual Laboratory features, use AR features, connect AR with chemistry content, develop learning activity scenarios, and conduct learning simulations. The results showed that after the training, 19 teachers (95%) were able to access the Virtual Laboratory, 18 teachers (90%) were able to operate Virtual Laboratory features, and 18 teachers (90%) were able to use AR features. Furthermore, 17 teachers (85%) were able to connect AR with chemistry content, while 16 teachers (80%) were able to develop learning activity scenarios and conduct learning simulations. These findings indicate that practice-based training can strengthen teachers’ technical and integrative skills in utilizing educational technology for chemistry learning.
