This study aims to learn the technique of Marker Based Tracking Augmented Reality which is implemented for Visualization of Anatomy of Human Body Organs. Augmented Reality Visualization Applications Anatomy of the Human Body Organ is built on the Android mobile platform device. In the analysis of the application interface design using the approach of User Center Design. Testing the application using Usability Test. Based on the results of implementation and testing, Marker Based AR technique successfully applied in making Visualization Applications Anatomy Human Body Organs on Android Platform. Applications use markers to display digital content 2D images of the brain, eyes, heart, and lungs. The results of the Usability Test show users can see organ anatomy information very clearly and users are very interested in using the applications created because it provides a different experience in learning.
