<![CDATA[This study aims to design and develop a digital learning media based on Augmented Reality (AR) for cube geometric shapes material in grade VIII of junior high school that is valid and feasible according to material and media experts. The research and development (R&D) method used follows the ADDIE framework, which is restricted to the development and evaluation phases through expert appraisal. Data collection instruments consisted of material and media validation sheets using a Likert scale. The results of this study outline the step-by-step development process using Assembler Edu integrated with PowerPoint. The validation analysis technique utilizes percentage formulas to convert quantitative data into qualitative feasibility criteria, requiring a minimum score of 61% to be declared feasible for mathematics.]]>
