Augmented Reality Application Development on Universitas Airlangga Museum's Sculpture as Hindu-Buddhist History Educational Media

History learning generally tends to be conventional by using textbooks and student worksheets, moreover, history education is considered a boring and less attractive course because it tends to memorization learning. This study aimed to develop the bhagya application, an augmented reality application on the sculptures of the Universitas Airlangga History and Culture Museum as a media for Hindu-Buddhist history education and to determine the effectiveness of augmented reality media as an educational medium. This study implemented the ADDIE method which consists of five stages, analysis, design, development, implementation, and evaluation. In the evaluation stages, four tests were carried out those are material and media validation testing, black box testing, effectivity testing, and user response testing. This study gave the result that this application is a very valid application for the media and material fields which was assessed by four experts with an average score for each field of 97.39% and 94.29%. This application obtained a positive response based on the results of the user response test of 89.77% with the "very good" category. This application was quite effective as an educational medium obtained from the effectiveness test with a normalized gain score of 0.55 in the moderate category where there is an increase in the post-test value of the respondent's pre-test score. In this study, the augmented reality application on the sculpture of the Museum of History and Culture of Universitas Airlangga was successfully developed with the results of user responses being in the very good category and quite effective as an educational medium. It is suggested that further research will be able to measure the level of effectiveness and the level of a user response at all levels of education.
