Penelitian ini bertujuan untuk mendeskripsikan kemampuan berpikir aljabar dan learning obstacle yang dialami oleh siswa SMP pada materi Persamaan dan Pertidaksamaan Linear Satu Variabel. Penelitian ini menggunakan metode kualitatif dengan pendekatan fenomenologi. Pengumpulan data dilakukan dengan menggunakan observasi dan instrumen yaitu tes tertulis dan wawancara. Berdasarkan kemampuan matematis yang diperoleh dari guru matematika dan hasil tes tertulis dari 32 siswa, terpilih enam responden untuk dilakukan wawancara pendalaman. Berdasarkan temuan dan pembahasan dalam penelitian ini, penulis menemukan siswa yang memiliki kemampuan matematis tinggi hanya dapat memenuhi dua indikator yaitu generalisasi dan transformasi, sedangkan siswa dengan kemampuan matematis sedang, dapat memenuhi indikator generalisasi dan baru mau mencapai tahap transformasi, kemudian siswa dengan kemampuan matematis rendah tidak dapat memenuhi semua indikator berpikir aljabar. Siswa dengan kemampuan matematis sedang dan rendah teridentifikasi mengalami hambatan belajar (learning obstacle), ada tiga jenis learning obstacle yang ditemukan yaitu ontogenic obstacle, didactical obstacle dan epistemological obstacle. The purpose of this research is to describe the algebraic thinking ability and the learning obstacles experienced by junior high school students on Linear Equations and Inequalities in One Variable. This is a qualitative research that used a phenomenological approach. The data used was collected through observation, written tests, and interviews. Based on the mathematical abilities obtained from the mathematics teacher and the written test results of 32 students, six respondents were selected for in-depth interviews. From the findings and the discussions in this research, the author found that students who have high mathematical abilities can only meet two indicators: generalization and transformation; the students with moderate mathematical abilities can only meet generalization indicators and were just about to reach the transformation stage; and last, the students with low mathematical abilities cannot fulfill all the indicators of algebraic thinking ability. The students with moderate and low mathematical abilities were identified as having learning obstacles. There were three types of learning obstacles found: ontogenic obstacle, didactical obstacle and epistemological obstacle.
