Kemampuan pemecahan masalah matematis merupakan kemampuan untuk
menyelesaikan dan mencari solusi dari suatu kesulitan permasalahan. Kemampuan
pemecahan masalah matematis sangat penting dalam pembelajaran matematika
sehingga perlu dimiliki oleh siswa. Penelitian ini bertujuan untuk mendeskripsikan
kemampuan pemecahan masalah matematis siswa pada materi SPLDV di SMP
Negeri 7 Banda Aceh. Jenis penelitian yaitu kualitatif deskriptif. Subjek dalam
penelitian yaitu 6 siswa yang mewakili kemampuan pemecahan masalah matematis
kategori tinggi, sedang, dan rendah. Instrumen yang digunakan adalah tes
kemampuan pemecahan masalah matematis dan pedoman wawancara. Pengumpulan
data dilakukan melalui soal tes kemampuan pemecahan masalah matematis dan
wawancara. Data penelitian dianalisis melalui 3 tahapan yaitu, reduksi data, penyajian
data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa kemampuan
pemecahan masalah matematis siswa dalam menyelesaikan masalah sistem
persamaan linear dua variabel (SPLDV) bervariasi. Siswa dengan kategori tinggi
dapat melaksanakan semua tahapan kemampuan pemecahan masalah menurut Polya
(memahami masalah, merencanakan penyelesaian, melaksanakan penyelesaian, dan
memeriksa kembali) dengan baik. Siswa dengan kategori sedang hanya melaksanakan
3 tahapan kemampuan pemecahan masalah, yaitu memahami masalah, merencanakan
penyelesaian, dan melaksanakan penyelesaian, namun tidak melaksanakan tahapan
memeriksa kembali. Sementra itu, siswa dengan kemampuan rendah hanya mampu
melaksanakan tahapan memahami masalah.
Kata kunci: Kemampuan pemecahan masalah, SPLDV, Tahapan pemecahan

Zahidah. (2026). Students’ Mathematical Problem-Solving Ability on System of Linear Equations in Two Variables at SMP Negeri 7 Banda Aceh. [Thesis. Syiah Kuala University]. Supervised Dra. Bintang Zaura, M.Pd., dan Dra. Ellianti, M.Pd. Mathematical problem-solving ability is the ability to resolve and find solutions to challenging problems. Mathematical problem-solving ability is essential in mathematics learning and therefore needs to be possessed by students. This research aims to describe students’ mathematical problem-solving abilities on the topic of system of linear equations in two variables (SPLDV) at SMP Negeri 7 Banda Aceh. The type of research is descriptive qualitative. The subjects in the research were 6 students representing high, medium, and low categories of mathematical problemsolving ability. The instruments used were a mathematical problem-solving test and interviews. The research data were analyzed through three stages, namely data reduction, data presentation, and conclusion drawing. The results of the research show that students’ mathematical problem-solving abilities in solving systems of linear equations in two variables vary. Student in the high category were able to perform all stages of mathematical problem solving according to Polya, (namely understanding the problem, devising a plan, carrying out the plan, and looking back) effectively. Students in the medium category were able to perform only three stages of mathematical problem solving, namely understanding the problem, devising a plan, and carrying out the plan, but were unable to perform looking back stage. Meanwhile, students in the low category were only able to perform the stage of understanding the problem. Keywords : Mathematical problem-solving ability, System of linear equations in two variables, Polya’s problem-solving stages
