Penelitian yang berjudul “Pengembangan Media Pembelajaran Konsep Koloid Berbasis Reels Instagram” ini bertujuan untuk mengetahui kelayakan dan tanggapan peserta didik terhadap media pembelajaran berbasis reels instagram. Penelitian ini menggunakan jenis penelitian Research and Development (R&D) dengan model pengembangan 4-D yang terdiri dari empat tahap, yaitu tahap Pendefinisian (Define), Perancangan (Design), Pengembangan (Development) dan Penyebaran (Disseminate). Penelitian dilakukan di SMAN 3 Banda Aceh dengan subjek penelitian sebanyak 27 orang peserta didik kelas XI IPA 4 yang dipilih secara random sampling. Pengumpulan data diperoleh dari validasi kelayakan media dan tanggapan peserta didik terhadap media berbasis reels instagram. Pengolahan data menggunakan teknik statistik sederhana dalam bentuk perhitungan nilai rata-rata (mean). Hasil analisis data menunjukkan bahwa kelayakan media yang divalidasi oleh dua validator memiliki persentase rata-rata sebesar 94,2% yang termasuk kategori sangat layak. Tanggapan peserta didik terhadap media yang dikembangkan memiliki persentase rata-rata sebesar 91,2% yang termasuk kategori sangat baik. Berdasarkan hasil penelitian dapat disimpulkan bahwa media pembelajaran berbasis reels instagram pada materi koloid layak digunakan sebagai media dalam proses pembelajaran kimia pada konsep koloid.

Keywords: Learning Media, Instagram Reels, 4-D Development Model, Colloid System The research entitled "Development of Instagram Reels-Based Colloidal Concept Learning Media" aims to determine the feasibility and responses of students to Instagram reels-based learning media. This research uses Research and Development (R&D) research with a 4-D development model consisting of four stages, namely the Defining, Design, Development and Disseminate stages. The research was conducted at SMAN 3 Banda Aceh with 27 students of class XI IPA 4 selected by random sampling. Data collection was obtained from media feasibility validation and student responses to Instagram reels-based media. Data processing uses simple statistical techniques in the form of calculating the average value (mean). The results of data analysis show that the media feasibility validated by two validators has an average percentage of 94.2% which is included in the very feasible category. Students' responses to the developed media have an average percentage of 91.2% which is included in the very good category. Based on the results of the study, it can be concluded that the learning media based on Instagram reels on colloidal material is feasible to be used as a medium in the chemistry learning process on the colloid concept.
