<![CDATA[The results of the cognitive diagnostic assessment showed that students’ literacy and numeracy abilities varied, with 58% in the low category, 18% in the moderate category, and 23% in the high category. In addition, 75% of students had not achieved the Learning Achievement Criteria (KKTP) in Science and Social Studies (IPAS) and Mathematics. This condition indicates the need for interactive and meaningful learning media that can accommodate students’ learning needs. This study aimed to develop, analyze the feasibility, and examine the effectiveness of Jejak Itah (Interactive Exploration of Central Kalimantan Culture), a learning medium based on ethnomathematics, ethnoscience, local culture, Islamic values, and digital technology to support Deep Learning implementation in elementary schools. The study employed a Research and Development (R&D) method using the ADDIE model, consisting of analysis, design, development, implementation, and evaluation stages. The subjects were 22 sixth-grade students at SD Muhammadiyah Pahandut. Data were collected through diagnostic assessments, expert validation, observations, student response questionnaires, and pretest-posttest assessments, then analyzed using percentages and N-Gain. The results showed that Jejak Itah was highly feasible based on media expert validation (95.83%), mathematics content (92.00%), science content (98.00%), and Islamic integration (97.14%). The medium received very positive responses and improved learning outcomes, with an N-Gain score of 0.83 (high category). Therefore, Jejak Itah is feasible as an innovative learning medium based on local culture and digital technology.]]>
