<![CDATA[The mathematical problem-solving ability of Grade X students at SMK Istiqlal Delitua remains relatively low, particularly in understanding problems, planning strategies, carrying out solutions, and checking results. This condition indicates the need for engaging and contextual learning media that connect mathematical content with students’ cultural experiences. This study aimed to develop Animaker learning media integrated with Rumah Joglo local wisdom and determine its validity, practicality, effectiveness, and improvement in students’ problem-solving ability. The study employed Research and Development (R&D) using the ADDIE model, consisting of Analysis, Design, Development, Implementation, and Evaluation. Trials included individual, small-group, and field trials involving 35 Grade X students. Data were collected through expert validation, teacher and student response questionnaires, and problem-solving tests, then analyzed using Aiken’s V, percentages, and N-Gain. The results showed a validity score of 95.14%, categorized as highly valid, and an average practicality score of 88.07%, categorized as highly practical. The average score increased from 46.57 to 87.43, with an N-Gain of 0.76, categorized as high. Thus, the Animaker media integrated with Rumah Joglo local wisdom is feasible as an alternative mathematics learning medium for improving students’ problem-solving ability through contextual and culturally relevant learning experiences.]]>
