The primary objective of this research is to assess the reading comprehension material needs of both students and teachers, with a specific focus on multimodal descriptive text and product design explanations. Additionally, the study aims to create a reading comprehension material model using Google Site as a platform and evaluate its effectiveness in improving students' comprehension of descriptive text. Following the research and development (R&D) method, which emphasizes creating novel products or refining existing ones, the chosen R&D model is the ADDIE development model comprising five stages: Analysis, Design, Development, Implementation, and Evaluation. The research involved 10th-grade students from SMA N 8 Semarang. Key findings include: 1.) Students emphasize the importance of interactive and enjoyable material models for effective learning, while teachers recognize the need for diverse material options in schools. 2.) The model of reading comprehension materials, centered on multimodal descriptive text using Google Site, is tailored for Senior High School students. 3.) The efficacy test conducted on the developed products yielded positive outcomes, indicating their suitability as instructional models and their potential to enhance students' reading comprehension skills. Consequently, the multimodal descriptive text-based reading comprehension material model through Google Site is recommended to bolster students' reading comprehension abilities in the classroom.
