Berhitung termasuk suatu hal yang sifatnya abstrak menjadi tantangan tersendiri bagi peserta didik disabilitas intelektual ringan. Namun kemampuan berhitung harus tetap diberikan kepada peserta didik disabilitas intelektual ringan karena berhitung bermanfaat dalam kehidupan sehari-hari, oleh karena itu diperlukan media pembelajaran konkrit untuk membantu peserta didik disabilitas intelektual ringan belajar kemampuan berhitung. Tujuan penelitian ini yakni membuktikan adakah pengaruh media pohon angka terhadap kemampuan berhitung pada peserta didik disabilitas intelektual ringan.

Penelitian ini menggunakan pendekatan penelitian kuantitatif dengan jenis penelitian pre-experimental dengan design one group pre-test post-test design. Teknik pengumpulan data yang digunakan yakni tes, dengan subjek penelitian sebanyak 6 peserta didik disabilitas intelektual ringan. Teknik analisis data menggunakan uji Wilcoxon match pair test. Hasil penelitian ini menunjukkan bahwa pretest peserta didik disabilitas intelektual mendapat nilai rata-rata 45 dan posttest mendapatkan nilai rata-rata 75. Sehingga terdapat pengaruh penerapan media pohon angka terhadap kemampuan berhitung peserta didik disabilitas intelektual ringan

Kata kunci: disabilitas intelektual ringan, berhitung, media pohon angka.

Counting is an abstract thing that becomes a challenge for students with mild intellectual disabilities. However, counting skills must still be given to students with mild intellectual disabilities because counting is useful in everyday life, therefore concrete learning media is needed to help students with mild intellectual disabilities learn counting skills. The purpose of this study is to prove whether there is an effect of number tree media on counting skills in students with mild intellectual disabilities.

This study uses a quantitative research approach with a pre-experimental type of research with a one group pre-test post-test design. The data collection technique used was a test, with 6 research subjects with mild intellectual disabilities. The data analysis technique used the Wilcoxon match pair test. The results of this study indicate that the pretest of students with intellectual disabilities gets an average score of 45 and the posttest gets an average score of 75. So that there is an effect of applying number tree media on the counting ability of students with mild intellectual disabilities.
