Penelitian ini dilatarbelakangi oleh rendahnya kemampuan penalaran matematika siswa Sekolah Menengah Atas (SMA) dalam matematika. Siswa mengalami kesulitan dalam pembelajaran materi geometri ruang. Penelitian ini bertujuan untuk mengetahui gambaran kemampuan penalaran matematika siswa SMA pada materi geometri ruang. Metode penelitian ini adalah kualitatif deskriptif dengan menganalisis kemampuan penalaran siswa dari instrumen yang diberikan. Instrumen dalam penelitian ini berbentuk tes tertulis yang berjumlah 5 soal. Berdasarkan hasil penelitian penelitian di SMA YPI Tunas Bangsa Palembang diperoleh nilai rata-rata kemampuan penalaran matematika siswa sebesar 66,11 yang tergolong cukup. Secara keseluruhan, indikator kemampuan penalaran matematika yang banyak dikuasai siswa adalah menyajikan pernyataan matematika dengan gambar dan tulisan, sedangkan indikator kemampuan penalaran matematika yang kurang dikuasai siswa adalah menarik kesimpulan dari suatu pernyataan. This research is motivated by the low mathematical reasoning abilities of high school students in mathematics. Students experience difficulties in learning space geometry material. This study aims to describe the mathematical reasoning abilities of high school students in space geometry. The method of this research is descriptive qualitative by analyzing the students' reasoning abilities of the given instrument. The instruments in this study were in the form of written tests totaling 5 questions. Based on the results of research at Tunas Bangsa Palembang YPI High School, the average mathematical reasoning ability of students of 66.11 was obtained as an average. Overall, the indicator of mathematical reasoning abilities that are controlled by many students is presenting mathematical statements with images and writing, while indicators of mathematical reasoning abilities that are less mastered by students are drawing conclusions from a statement.
