Black Box Testing on Android-Based Augmented Reality Application of Human Digestive System

Abstrak

The development of digital technology in education has encouraged the use of more interactive learning media to improve students’ understanding of learning materials. One of the science subjects considered difficult for junior high school students is the human digestive system because the digestive process and organ structures cannot be observed directly. Based on these problems, this study aims to develop an Android-based Augmented Reality application for the Human Digestive System as an interactive learning medium and to implement the Black Box Testing method to evaluate the functionality of the application system. The software development method used in this research is Rapid Application Development (RAD) with marker-based tracking technology. This study applied a qualitative research method with data collection techniques consisting of observation, interviews, and literature study. Black Box Testing was conducted to determine the suitability of system functions based on input and output without analyzing the internal structure of the program code. The testing process involved 172 test scenarios covering marker scanning, 3D object visualization, rotation features, audio, video, learning materials, quizzes, navigation, and application exit functions. The results showed that all application features functioned properly according to expectations without any functional errors. The application was able to display 3D models of human digestive organs effectively and provide interactive features that support the learning process. Therefore, the Android-based Augmented Reality Human Digestive System application is considered feasible and effective as an interactive and educational learning medium.
