<![CDATA[Abstrak — Penelitian ini bertujuan untuk mengimplementasikan model pembelajaran inkuiri terbimbimbing menggunakan variasi media untuk meningkatkan pemahaman peserta didik pada mata kuliah sistem operasi. Variasi media bertujuan untuk memberikan hal yang menarik dengan penjelasan yang lebih rinci. Pada aplikasi terdapat petunjuk, tujuan, materi, video pembelajaran, kuis dan tentang. Pembuatan aplikasi menggunakan metode Rapid Prototyping Model yaitu, asses needs and analyze content, set objektives, contruct prototype (design), utility prototype (research), install and maintance system. Aplikasi android dibuat dengan power point, ispring suite 10 dan website Apk 2 builder pro. Proses editing audio dan video menggunakan software Camtasia 2021. Hasil evaluasi test kepada peserta didik rata-rata nilainya 65,55. Hasil survei umpan balik kepada peserta didik tentang aplikasi sistem operasi secara keseluruhan kategori baik dengan perbandingan sebelum revisi dan sesudah revisi. Pemahaman peserta didik pada materi sistem operasi paling tinggi kategori memahami sebesar 50%. Kata Kunci — Inkuiri Terbimbing, Rapid Prototyping Model, Variasi Media Abstract — This study aims to implement guided inquiry learning models using a variety of media to increase students' understanding of operating systems courses. Media variations aim to provide interesting things with more detailed explanations. In the application there are instructions, objectives, materials, learning videos, quizzes and about.
