<![CDATA[Background – Fifth-grade learners at SDN Bangka 3 reported difficulties recalling Sundanese script forms and applying rarangkén, alongside limited concrete instructional media. Purpose – This study developed Sundanese script matching cards and described expert appraisals and user responses. Method/Approach – An adapted 4-D model guided development, appraisal, revision, and local handover. One media expert and one content expert assessed the initial prototype. Testing comprised a five-student pilot and a 30-student Class VA trial; one classroom teacher supplied a response. Pilot/trial overlap was unspecified. Analysis was descriptive. Findings – Equal-weight means of displayed dimension percentages were 92.19% for media appraisal, 95.83% for content appraisal, 81.77% for student responses, and 83.44% for the teacher response. Raw-score denominators were unavailable for independent verification. A corrected “ja” card was checked by the competition coach but was not formally revalidated. Separate pilot results were not reported. Conclusion – The prototype received favourable expert and user appraisals. These findings concern preliminary feasibility and perceived acceptability, not learning effectiveness. Limited instrument documentation and a single-school sample constrain interpretation. Novelty/Originality/Value – The prototype integrates physical character matching, rarangkén composition, and board-based writing with teacher feedback. Its contribution is a documented local product adaptation rather than demonstrated superiority over existing media.]]>
