The purpose of this study is to develop, test the feasibility, and test the effectiveness of Augmented Reality Book (AR-Book) media in improving learning outcomes in human digestive system material of grade V students of SDN Kalibanteng Kidul 01. This research uses the Research and Development method with the ADDIE development model. The instruments used are questionnaires and test questions. Product validity tests are carried out by material and media experts. The results of this research are: AR-Book development design as a learning medium; media notability of AR-Books by 90% media experts and 92% of materials rated "very valid"; teacher and student responses to AR-Book were "very interesting" with a percentage of teachers 92% and students 93.7%; The effectiveness of the media from the t test results showed a GIS (2-tailed) value of 0.000 < 0.05 which means there is a significant difference from the average results before treatment and after treatment and the N-Gain test which shows a value of 0.71 which means there is a significant increase in the high category.
