<![CDATA[This study is a type of research and Development (R&D) which aims to develop augmented Reality (AR) based learning media on the topic of the human digestive system for high school students. This study was initiated because of the increasing need for interactive learning media that are able to visualize abstract biological concepts and support * independent curriculum*, which emphasizes meaningful and technology-oriented learning. The development process follows the 4-D model (Define, Design, Develop, Disseminate) introduced by Thiagarajan, but this study was limited to the Develop stage due to time constraints. Research instruments include expert validation sheets, teacher and student practicalities questionnaires, and pretest and posttest assessments to measure media effectiveness. The validation results of 98% media experts and 88% material experts showed that the media is very feasible. The practical test received a score of 90% from teachers and 98% from students, both belonging to the “very practical”category. Furthermore, the effectiveness test showed an increase in students ' conceptual understanding, with an average N-Gain score of 76.52%, which is high. These results indicate that AR-based learning media are effective in increasing students ' engagement and conceptual understanding of the human digestive system.]]>
