Penelitian ini bertujuan untuk menentukan validitas, reliabilitas, dan kepraktisan media video animasi berbasis TikTok pada materi konfigurasi elektron. Model pengembangan yang digunakan adalah ADDIE yang terdiri dari analisi (analysis), desain (design), pengembangan (develop), implementasi (implementation), dan evalusi (evaluation). Namun, penelitian ini dibatasi hanya sampai tahap pengembangan (develop). Pengumpulan data dilakukan melalui angket kebutuhan, validasi oleh ahli, serta uji coba terbatas kepada peserta didik dan guru. Hasil analisis kebutuhan menunjukkan bahwa peserta didik dan guru memandang materi konfigurasi elektron cukup sulit dipahami serta membutuhkan media pembelajaran yang singkat, menarik, dan interaktif. Sebanyak 52,4% peserta didik menyatakan video animasi dapat membantu memahami materi abstrak, dan 81% di antaranya terbiasa menonton konten edukatif di TikTok. Hasil validasi ahli menunjukkan media yang dikembangkan memiliki tingkat validitas sangat tinggi dengan nilai S-CVI sebesar 0,88 dan reliabilitas tinggi dengan nilai IRA sebesar 0,77. Uji coba terbatas yang melibatkan 21 peserta didik kelas X memperoleh respon positif dengan persentase rata-rata 89,52%, sedangkan guru memberikan penilaian rata-rata 87,5%.

This study aims to determine the validity, reliability, and practicality of TikTok-based animated video media on electron configuration material. The development model used is ADDIE, which consists of analysis, design, development, implementation, and evaluation. However, this research was limited only to the development stage. Data were collected through needs questionnaires, expert validation, and limited trials with students and teachers. The results of the needs analysis showed that both students and teachers considered electron configuration material quite difficult to understand and required short, engaging, and interactive learning media. As many as 52.4% of students stated that animated videos could help them understand abstract material, and 81% were accustomed to watching educational content on TikTok. The results of expert validation showed that the developed media had a very high level of validity with an S-CVI value of 0.88 and high reliability with an IRA value of 0.77. Limited trials involving 21 tenth-grade students obtained positive responses with an average percentage of 89.52%, while teachers gave an average score of 87.5%.
