This research is a research and development study conducted to find out: the development process, feasibility, effectiveness, and practicality of developing BERBUKIT learning media for earth materials in IPAS subjects. The study used the ADDIE development model, which includes Analysis, Design, Development, Implementation, and Evaluation, using data collection techniques such as interviews, observations, and questionnaires, and to measure students' interest, a Paired Sample t-test was used. This research was conducted at SD Negeri Puluhan with the trial subjects being fifth-grade students. The results of this study are: (1) Learning tools in the form of BERBUKIT media based on needs analysis and curriculum analysis. Designing BERBUKIT media and product assessment instruments. (2) The learning tools are declared feasible based on the validity aspect, obtaining a score of 93.7% from content experts and a score of 93.2% from media experts. Based on practicality aspects, student responses showed a percentage of 85.10%, teacher response questionnaires showed a percentage of 82.50%, and the implementation observation sheets indicated very good criteria with a learning implementation percentage of 95%. Based on the effectiveness of the BERBUKIT learning media assisted by Augmented Reality, it was declared effective. This was obtained from the Paired Sample T-test, which resulted in a sig (2-tailed) value of 0.000 < 0.05. Therefore, it can be concluded that the implementation of the interactive BERBUKIT learning media assisted by Augmented Reality has an impact on increasing the learning interest of fifth-grade students at Puluhan State Elementary School.
