Kemampuan penalaran matematis merupakan salah satu kemampuan yang harus dimiliki oleh siswa dalam mempelajari matematika. Kenyataannya, kemampuan penalaran matematis siswa kelas VIII SMP Negeri 8 Banda Aceh masih tergolong rendah dan belum mencapai ketuntasan. sehingga dibutuhkan suatu model pembelajaran yang dapat meningkatkan kemampuan penalaran matematis siswa yaitu model Problem Based Learning. Tujuan dari penelitian ini adalah untuk mengetahui kemampuan penalaran matematis siswa melalui model pembelajaran Problem Based Learning pada materi sistem persamaan linear dua variabel dapat mencapai ketuntasan. Penelitian ini menggunakan pendekatan kuantitatif. Jenis yang digunakan dalam penelitian ini adalah quasi-experimental design, yang didesain dalam bentuk one group posttest-only design. Populasi penelitian ini adalah seluruh siswa kelas VIII SMP Negeri 8 Banda Aceh. Sampel yang dipilih adalah siswa kelas VIII-4 dengan jumlah 32 siswa. Teknik pengumpulan data dilakukan dengan pemberian soal tes kepada siswa setelah diterapkan model pembelajaran Problem Based Learning. Analisis data dilakukan dengan menggunakan uji-t pihak kanan dengan taraf signifikan α=0,05 dan dk = 31. Hasil analisis data diperoleh bahwa thitung > ttabel yaitu 4,22 > 1,69, sehingga dapat disimpulkan bahwa kemampuan penalaran matematis siswa melalui model pembelajaran Problem Based Learning pada materi sistem persamaan linear dua variabel dapat mencapai ketuntasan.

Salsabilla. (2024). Students Mathematical Reasoning Ability Through the Problem-Based Learning Model on the Topic of Systems of Linear Equations in Two Variables. [Skripsi.Universitas Syiah Kuala]. Under direction of Dra. Suryawati, M.Pd., dan Suhartati, S.Pd., M.Pd. Mathematical reasoning ability is one of the essential skills students must possess in learning mathematics. In reality, the mathematical reasoning ability of Grade VIII students at SMP Negeri 8 Banda Aceh is still relatively low and has not reached the minimum mastery criteria. Therefore, a learning model that can enhance students' reasoning abilities is needed, namely the Problem-Based Learning (PBL) model. The purpose of this study was to determine whether students’ mathematical reasoning ability through the implementation of the Problem-Based Learning model on the topic of systems of linear equations in two variables can reach mastery criteria. This study employed a quantitative approach. The research design used was a quasi-experimental design, specifically the one-group posttest-only design. The population of this study included all Grade VIII students at SMP Negeri 8 Banda Aceh. The sample consisted of 32 students from class VIII-4. Data collection was conducted through a test administered after the implementation of the Problem-Based Learning model. The data were analyzed using a one-tailed t-test with a significance level of α = 0.05 and degrees of freedom (df) = 31. The results showed that t_calculated > t_table, namely 4.22 > 1.69. Therefore, it can be concluded that students’ mathematical reasoning ability through the Problem-Based Learning model on the topic of systems of linear equations in two variables has reached the mastery criteria.
