<![CDATA[This study aimed to develop RANTING IDE, a learning application designed to help elementary school students distinguish between main ideas and supporting ideas. The study employed a Research and Development (R&D) method using the ADDIE model, consisting of Analysis, Design, Development, Implementation, and Evaluation stages. The feasibility of the application was assessed through expert validation, while its practicality was examined based on student responses. The results showed that the validation score from the media expert reached 95%, categorized as highly feasible, while the material expert validation score reached 96.6%, also categorized as highly feasible. Furthermore, students’ responses to the RANTING IDE application were highly positive, with an average score of 92%, categorized as very good. These findings indicate that the RANTING IDE application is highly feasible for use in Indonesian language learning, particularly to assist students in distinguishing main ideas from supporting ideas. The application is expected to serve as an educational innovation that facilitates students’ understanding of texts through an engaging and accessible digital learning medium. Thus, RANTING IDE has potential as an alternative learning resource for supporting reading comprehension in elementary education.]]>
