This study aims to develop learning media based on Augmented Reality (AR) multimedia in the Balinese Traditional Game Megoak-goakan. The research method used is the research and development method with the Dick and Carey development research model and literature review on the benefits and affordability of AR. The stages in this development research are 1) needs analysis, 2) development of Augmented Reality-based learning media, and 3) product validation test. Data collection for learning media validation uses an assessment instrument with a Likert scale. The results of this development research in the form of software with Augmented Reality technology on Optical Instruments. Augmented Reality-based multimedia learning media has gone through a validation test stage with an average percentage of achievement of 91% according to material experts and 90% according to learning media experts. From the results of this study, it can be concluded that Augmented Reality-based multimedia learning media meets the requirements with quality very good to be used as a supporting medium in the traditional game of Megoak-goakan learning activities.
