<![CDATA[AbstrakTujuan penelitian ini adalah untuk mengembangkan media pembelajaran geometri bangun ruang adaptif (BARUSIDA) yang valid, praktis, dan efektif dalam meningkatkan pemahaman konsep siswa tunanetra di sekolah inklusi. Media BARUSIDA adalah alat peraga nyata pada topik bangun ruang sisi datar yang didesain dengan memanfaatkan modalitas taktil siswa tunanetra, penulisan huruf Braille, serta dapat dibongkar-pasang seperti puzzle agar mereka dapat mengkonstruksi lebih dari satu jenis model bangun ruang sisi datar secara fleksibel. Metode penelitian yang digunakan adalah penelitian pengembangan model Plomp yang terdiri dari 5 fase, yaitu: (1) investigasi awal; (2) desain; (3) konstruksi; (4) tes, evaluasi, revisi; dan (5) implementasi. Penelitian ini dilakukan di SMP Modern Islamic School (MIS) sebagai salah satu sekolah inklusi yang melayani siswa tunanetra di Surakarta. Penelitian ini dilakukan secara terbatas pada 3 siswa tunanetra sebagai subjek penelitian dikarenakan kondisi pandemi Covid-19. Teknik analisis data untuk uji efektivitas adalah Single Subject Research dengan model Multiple Baseline Design tipe A-B. Hasil yang diperoleh adalah media BARUSIDA yang valid, praktis, dan efektif. Media BARUSIDA dinyatakan valid berdasarkan hasil validasi ahli. Media BARUSIDA dinyatakan praktis karena diperoleh tingkat keterlaksanaan media dan keinginan penggunaan media berada pada kategori Baik dan Sangat Baik dengan rerata skor angket respon guru sebesar 3,214, rerata skor angket respon dua orang siswa sebesar 3,2, serta rerata skor respon seorang siswa sebesar 3,5. Media BARUSIDA dinyatakan efektif karena terdapat peningkatan skor pemahaman konsep dari baseline ke treatment sebesar 1 sampai 3 poin setelah dilakukan beberapa sesi pertanyaan wawancara berbasis tugas terkait indikator pemahaman konsep.Kata Kunci: Bangun Ruang Sisi Datar, Media Pembelajaran Adaptif, Pemahaman Konsep, Sekolah Inklusi, Siswa Tunanetra. AbstractThis research aims to develop a valid, practical, and effective adaptive polyhedron learning media in geometry. The media is labeled as BARUSIDA. BARUSIDA is a real learning media in the form of concrete manipulatives on polyhedrons in geometry, designed by considering the tactile principles of visually impaired students. BARUSIDA can represent more than one type of geometry shape because it can be assembled flexibly like a puzzle so that visually impaired students can construct some solid geometry shape models. The method used in this research is development research which refers to the Plomp development model. The Plomp development model consists of 5 phases, namely: (1) preliminary investigation, (2) design, (3) construction, (4) test, evaluation, and revision, and (5) implementation. This research was conducted at SMP Modern Islamic School (MIS) as one of the inclusion schools serving visually impaired students in Surakarta. This research was conducted very carefully and was limited to 3 blind students due to the Covid-19 pandemic conditions.  The results obtained in this research is valid, practical, and effective BARUSIDA learning media. BARUSIDA was declared valid after there were no comments or suggestions for improvement from experts after a series of expert validation processes had been carried out. BARUSIDA media is stated to be practical with the mean score of the level of media implementation and the desire to use media from the teacher’s response questionnaire of 3.214, the mean score of the two students’ questionnaire responses is 3.2, and the average response score of a student is 3.5. BARUSIDA media was declared effective with increased concept understanding scores from baseline to treatment, which ranged from 1 to 3 points after several sessions of task-based interview questions related to concept understanding indicators.Keywords: Development Research, Manipulatives, Polyhedron, Concept Understanding, Visually Impaired Students, Inclusive Schools.]]>
