<![CDATA[This study aims to develop valid and practical augmented reality (AR)-based learning media to support Kepler's Law learning at the high school level. The research method used is the ADDIE (Analysis, Design, Development, Implementation, Evaluation) development model, which provides a systematic approach in designing and implementing learning media. The population of this study were students of SMA Negeri 6 Pekanbaru, with a sample of grade XI students selected using a purposive sampling technique. Data were collected through validity tests by experts and practicality tests by students. Data analysis techniques used include validity analysis with the Aiken V index and practicality analysis using the Likert scale. The results showed that the AR application developed had a high level of validity with an Aiken V index score of 0.99, which reflects the suitability and consistency of expert assessments. Meanwhile, the practicality of the application was assessed as high with an average score of 4.3 based on student evaluations. Thus, this AR learning media is declared valid and practical for use in high school physics learning, especially in the material of Kepler's Law and Newton's Law of Gravity]]>
