Abstract: The low mathematics learning outcomes and students’ lack of conceptual understanding have become a problem in the learning process of class XII SMK N 1 Merangin. This condition causes students to be less active and less able to solve mathematical problems independently. This study aims to improve students’ mathematics learning outcomes through the implementation of the Problem Based Learning (PBL) model assisted by peer tutoring discussions. This research uses the Classroom Action Research (CAR) method which was carried out in two cycles, namely cycle I and cycle II involving 26 students of class XII AKL SMK N 1 Merangin. Data were collected through learning achievement tests in each cycle and student activity observations. The results showed a significant improvement from cycle I to cycle II. The average score in cycle I was 67.3 with a total score of 1,750, while in cycle II it increased to 99.2 with a total score of 2,580. This improvement indicates that the implementation of the Problem Based Learning (PBL) model is effective in increasing students’ activeness and learning outcomes in mathematics learning. Therefore, it can be concluded that the Problem Based Learning (PBL) model is effective in improving mathematics learning outcomes of class XII students at SMK N 1 Merangin. Abstrak Rendahnya hasil belajar matematika siswa serta kurangnya pemahaman konsep menjadi permasalahan dalam proses pembelajaran di kelas XII SMK N 1 Merangin. Kondisi ini menyebabkan siswa kurang aktif dan kurang mampu menyelesaikan permasalahan matematika secara mandiri. Penelitian ini bertujuan untuk meningkatkan hasil belajar matematika siswa melalui penerapan model pembelajaran Problem Based Learning (PBL) dengan bantuan diskusi tutor sebaya. Penelitian ini menggunakan metode Penelitian Tindakan Kelas (PTK) yang dilaksanakan dalam dua siklus, yaitu siklus I dan siklus II dengan subjek 26 siswa kelas XII AKL SMK N 1 Merangin. Teknik pengumpulan data dilakukan melalui tes hasil belajar pada setiap siklus serta observasi aktivitas siswa. Hasil penelitian menunjukkan adanya peningkatan yang signifikan dari siklus I ke siklus II. Rata-rata nilai siswa pada siklus I sebesar 67,3 dengan jumlah nilai keseluruhan 1.750, sedangkan pada siklus II meningkat menjadi 99,2 dengan jumlah nilai keseluruhan 2.580. Peningkatan ini menunjukkan bahwa penerapan model Problem Based Learning (PBL) mampu meningkatkan keaktifan dan hasil belajar siswa dalam pembelajaran matematika. Dengan demikian, dapat disimpulkan bahwa model Problem Based Learning (PBL) efektif digunakan dalam meningkatkan hasil belajar matematika siswa kelas XII SMK N 1 Merangin.
