21st-century education demands the development of higher-order thinking skills (HOTS) in students through contextual, collaborative, and technology-based learning. The material on reaction rates in chemistry is often challenging for students due to its abstract and complex nature, thus requiring innovative learning media to support conceptual understanding and HOTS development. This study aims to analyze the need for interactive multimedia development on reaction rate material to foster HOTS in 11th-grade high school students, focusing on students, teachers, media, facilities, and curriculum integration. The research method used is descriptive qualitative, involving questionnaires, interviews, and observations of 100 students and 1 chemistry teacher at SMA N 2 Sungai Selan. The results showed that students' need for interactive multimedia reached 92.79% (very needed category), especially to understand abstract concepts and increase learning motivation. Teachers' need for HOTS-based learning media reached 80.00% (very needed category), with existing potential that still requires improvement in its implementation. Students' readiness to use digital devices and the availability of school facilities support the development of interactive media. Based on these findings, developing HOTS-based interactive multimedia on reaction rate material is essential to enhance students' conceptual understanding, active involvement, and high-level thinking skills.
