<![CDATA[Numeracy is one of the essential competencies that needs to be developed in students with special needs, particularly in Mathematics learning at Special Education Elementary Schools (SDLB). The diversity of student characteristics requires learning media that is adaptive, concrete, interactive, and accessible according to each student's learning needs. This study aims to develop and determine the effectiveness of the BAKENA (Adaptive Learning for Numeracy Skills of Children with Special Needs) Interactive Learning Media in supporting the improvement of numeracy skills of fifth-grade SDLB students on number material 1-200. This study used the Research and Development (R&D) method with stages of needs analysis, design, development, implementation, and evaluation. BAKENA was developed based on HTML with features including materials, numeracy games, exercises, evaluation, feedback, and learning adjustments based on the characteristics of students with Intellectual Disability, Hearing Impairment, Learning Difficulties, Autism, and Low Vision. The media also integrates elements of Central Kalimantan culture through the Betang House, Dayak motifs, local environment, and the Hornbill bird. Implementation results on 9 students showed an increase in numeracy skills after using BAKENA. The average N-Gain was 0.55, in the moderate category, with 7 students in the moderate category and 2 students in the high category. These results indicate that BAKENA can serve as an alternative learning medium that supports the improvement of numeracy skills of SDLB students through an adaptive, interactive, concrete, accessible, and contextual learning approach]]>
