PENGEMBANGAN MEDIA PEMBELAJARAN TEKS DESKRIPSI BERBASIS ASSEMBLR EDU BERMUATAN KEARIFAN BUDAYA LOKAL KALIMANTAN TENGAH PADA SISWA KELAS XII

Teaching descriptive text writing in senior high schools requires students to observe objects in detail, develop imagery, and express their observations in coherent and meaningful written language. However, classroom practices are still dominated by conventional learning media that do not adequately support concrete and contextual visualization, resulting in low-quality descriptive texts produced by students. In addition, the potential of local cultural wisdom as an authentic learning resource has not been optimally utilized. This study aimed to develop descriptive text learning media based on Assemblr Edu integrated with the local cultural wisdom of Central Kalimantan and to examine its feasibility and effectiveness in Indonesian language learning for twelfth-grade students. This study employed a research and development approach using the ADDIE model, which includes analysis, design, development, implementation, and evaluation stages. The research subjects involved Indonesian language teachers and twelfth-grade students at SMA Muhammadiyah 1 Palangka Raya and SMA NU Palangka Raya. Data were collected through observation, interviews, questionnaires, and descriptive writing tests. The results showed that the developed learning media were categorized as highly feasible based on validation by media experts, subject-matter experts, and teaching practitioners. The field trial results indicated that the media were effective in improving students’ descriptive writing skills, as reflected in better text structure, more detailed descriptions, and stronger relevance to local cultural contexts. Therefore, descriptive text learning media based on Assemblr Edu integrated with Central Kalimantan local cultural wisdom are feasible and effective for use in Indonesian language learning at the senior high school level.
