The method used is the ADDIE RD model with the stages of Analysis, Design, Development, Implementation, and Evaluation. Data were collected through observation, interviews, documentation, validation sheets, assessments, and tests. Data analysis was carried out using qualitative and quantitative descriptive techniques. The results showed that AR IPAS media integrates the real and virtual worlds, and provides interactive and real-time information in 2D and 3D, made with the Assemblr Edu application. This media is effective, easy to operate, and affordable to make. However, AR media is sensitive to changes in viewing angle and requires sufficient memory capacity on the device used. The implementation of AR IPAS media at SD Negeri Nanggulan and MI Al-Huda was conducted in five meetings, students were enthusiastic and actively involved, allowing direct concept exploration. AR IPAS media products are proven to be effective, proven through paired sample t-tests on two classes showing significance p 0.05, indicating a significant difference in students' critical thinking skills before and after using AR media.]]>
