This research focused on the low level of understanding of grade 3 students at MI Elpist Temanggung Central Java towards the Javanese language in Temanggung dialect or Basa Temanggungan. It was caused by the dominance of the use of Indonesian in everyday life and was reinforced by the influence of language through digital media. Another contributing factor was the negative perception of the Temanggung dialect, which needed to be more modern, thus affecting students' motivation to learn and use this language. The research method used the ADDIE model (Analysis, Design, Development, Implementation, Evaluation) to develop flashcard-based learning media containing local wisdom. This flashcard integrated local cultural elements such as tembang dolanan, which not only served to improve vocabulary understanding but also instilled Temanggung cultural values. The research results showed that the use of flashcards significantly increased students' interest and understanding of Basa Temanggungan, especially in tembang dolanan materials such as "Cublak-Cublak Suweng" and "Sluku-Sluku Bathok". However, there were challenges in applying Krama vocabulary and limited learning time. This research emphasized the importance of collaboration between teachers, parents, and the social environment to enrich local language learning through more interactive and contextual methods in order to preserve regional languages and local wisdom systematically.
