This study aims to 1) Know the procedure for developing learning media based on audio-visual coupling system . 2) To find out the learning interest of students in the fourth semester of automotive engineering education at the Muhammadiyah University of Purworejo. 3) Make it easier for non-vocational students to understand the material of the power transfer system, especially in the 4 semester coupling system lessons at the Muhammadiyah University of Purworejo. 4) Increase students' interest in learning about the system material transfer of personnel, especially in the clutch system lesson in semester 4 of Muhammadiyah University of Purworejo. This study uses Research and Development (R & D) with subject research undertaken is the semester students of 4th grade B Automotive Engineering Education Purworejo Muhammadiyah University as many as 39 students. The data was collected using a questionnaire to determine the feasibility of the medium used using the student response sheet and the student learning interest questionnaire using the student learning interest questionnaire. From the results of the study, it shows that: 1) the procedure for developing learning media for the coupling audio visual system includes searching for potential problems, data collection, product design, design validation, design improvement, product testing, product testing, usage trials and product revisions . 2) media instructional audio visual system coupling system suitable for use in a medium of learning. This can be evidenced from media experts who showed a mean score - an average of 3, 1 . Validation from experts who showed an average score of 3.4. The learning media for the coupling system audio-visual system also meets the quality criteria of learning media. This is shown by the student response, namely the small group trial obtaining an average score of 3.43 which includes 5 students and the large group trial obtaining an average score of 3.13. 3) In student interest in learning, it shows that with the audio visual learning media the coupling system can increase the learning interest of 4th semester students of class B at the Muhammadiyah University of Purworejo. © 2020 Institute of Physics Publishing.
