<![CDATA[Fraction operation material in elementary schools is often considered difficult by students due to its abstract nature and the lack of interactive digital learning media. This condition has the potential to decrease students' interest and mathematics learning outcomes if not addressed with appropriate learning material innovations. Therefore, this study aimed to develop a multimedia-based e-module assisted by flipbook media on fraction operations material for fifth-grade elementary school students that is valid, practical, and has a potential effect. This study employed a Research and Development (R&D) method using the ADDIE model, which consists of the analyze, design, development, implementation, and evaluation stages. The study was conducted in the second semester of the 2025/2026 academic year at SD Negeri 157 Palembang. The results showed that the validation assessment conducted by media experts, material experts, and language experts obtained an average percentage of 92.66%, categorized as very valid. The student response questionnaire results indicated that the multimedia-based e-module obtained a percentage of 86.92%, falling into the very practical category. In addition, the effectiveness test results showed that the developed e-module achieved a percentage of 88.20%, indicating a potential effect on improving student learning outcomes with a very effective category. Thus, the developed multimedia-based e-module assisted by flipbook media is feasible, practical, and effective for use as a digital mathematics learning material in elementary schools. ABSTRAK Materi operasi hitung pecahan di sekolah dasar sering dianggap sulit oleh siswa karena konsepnya yang bersifat abstrak dan minimnya ketersediaan media pembelajaran digital yang interaktif. Kondisi tersebut berpotensi menurunkan minat serta hasil belajar matematika siswa jika tidak ditangani dengan inovasi bahan ajar yang tepat. Oleh karena itu, penelitian ini bertujuan untuk menghasilkan e-modul berbasis multimedia berbantuan flipbook pada materi operasi hitung pecahan untuk siswa kelas V sekolah dasar yang valid, praktis, dan memiliki efek potensial. Penelitian ini menggunakan metode penelitian dan pengembangan (Research and Development) dengan model ADDIE yang meliputi tahap analysis (analisis), design (perancangan), development (pengembangan), implementation (implementasi), dan evaluation (evaluasi). Penelitian dilaksanakan pada semester genap tahun ajaran 2025/2026 di SD Negeri 157 Palembang. Hasil penelitian menunjukkan bahwa penilaian validasi dari ahli media, ahli materi, dan ahli bahasa memperoleh rata-rata persentase sebesar 92,66% dengan kriteria sangat valid. Hasil angket respon siswa memperoleh persentase sebesar 86,92% yang termasuk dalam kriteria sangat practical (sangat praktis). Selain itu, hasil tes setelah implementasi menunjukkan persentase ketuntasan sebesar 88,20% yang mengindikasikan bahwa produk memiliki efek potensial yang sangat efektif terhadap peningkatan hasil belajar siswa. Dengan demikian, e-modul berbasis multimedia berbantuan flipbook ini dinyatakan sangat layak, praktis, dan efektif digunakan sebagai bahan ajar digital matematika di sekolah dasar. ]]>
