Human reproductive system is an important topic to be mastered by students in high school, however, the learning results of this topic in National Exam was still reported unsatisfactory. Therefore, developing a 3D-based learning media could be a potential solution to ease students in learning about this topic. We aimed to develop an Augmented Reality (AR) media on the human reproductive system topic, determine the feasibility and determine the effectiveness of using the media to improve students' cognitive abilities. This study used the ADDIE model (Analysis, Design, Development, Implementation, & Evaluation) and was conducted at SMAN 13 Jambi City. The test subjects were students of class XI in Science class. Data collection was performed with questionnaires to obtain product feasibility data based on validation results from experts, Biology teachers, and student responses. Multiple choice tests were used to obtain data on the effectiveness of using the media. The questionnaire data for the feasibility of the media were analyzed descriptively, while the effectiveness of the developed media were analyzed with Mann-Whitney test. The results showed that validation from both material and media experts are in very good category, scoring 100% and 95%, respectively. The response from biology teachers was also in good category, showing 92% as well as the result from the student's response (83.5%). Therefore, the developed AR media is considered suitable to be used in learning. The cognitive ability of students who are taught with and without AR media was not significantly different. The average posttest score for the treatment class was 49.23, gain=0,2; and the control class was 43.5, gain=0.1, p= 0.125). Although there is no significant difference in students' cognivite ability, there is a tendency of increasing students' learning outcomes using the AR media rather than not using the AR media.
