<![CDATA[Teaching poetry writing at the junior high school level requires engaging and interactive learning media to help students develop ideas and express them in poetic form. Therefore, learning media that support independent learning and facilitate students' understanding of poetry writing are needed. This study aims to develop Cerindo application-based learning media for poetry writing among students in Class VIII A at SMP Negeri 16 Pontianak and to determine its validity and practicality. This study employed the Research and Development (R&D) method using the 4D development model, which consists of four stages: define, design, develop, and disseminate. The research subjects were students in Class VIII A at SMP Negeri 16 Pontianak. Data were collected through expert validation sheets and student response questionnaires. Product feasibility was assessed by two validators, namely one media expert and one subject matter expert. The data were analyzed using quantitative descriptive techniques by converting assessment scores into percentages. The results showed that the Cerindo learning media achieved an overall validity score of 91%, categorized as highly valid, consisting of a material validity score of 90% and a media validity score of 92.5%. Meanwhile, the practicality test based on student responses yielded a score of 92.5%, categorized as highly practical. These findings indicate that Cerindo is suitable for use in teaching poetry writing. The application is expected to help students develop ideas and improve their poetry-writing skills independently through interactive content presentation.]]>
