This research aims to improve student accessibility and engagement in Islamic religious education through the development of a mobile application named AGAMIS (Aplikasi Gawai Mahir Agama Islam). The study was conducted at the Department of Business Administration, Politeknik Negeri Samarinda, focusing on Generation Z students who are highly accustomed to digital technologies. Using the ADDIE model for instructional design, the research adopted a Research and Development (R&D) approach to create an interactive platform offering features such as learning materials, quizzes, and discussion forums. After implementation and testing, the results showed a significant increase in student participation, motivation, and understanding, with 70% of the students demonstrating improved comprehension of the course content. This suggests that AGAMIS is an effective tool for enhancing student engagement in religious education. The findings contribute to the ongoing efforts in integrating technology in education, especially in the context of Islamic studies, and provide a foundation for future research in developing digital learning media.
