This study aims to determine how students' ability to solve mathematical problems on three-dimensional material improves after the implementation of the Problem Based Learning model assisted by GeoGebra. The subjects in this study were students of class XII MIPA 5 at SMA Negeri 5 Medan. The object of this study was to improve students' mathematical problem solving abilities by implementing the Problem Based Learning (PBL) model assisted by GeoGebra. The research instruments used were tests and observations. This study is a classroom action research with 2 cycles carried out in the odd semester of the 2024/2025 academic year. At the end of each cycle, a test was given to determine the improvement in students' mathematical solving abilities. The test results showed that there was an increase in the average value in the process of solving students' answers in each indicator of problem solving ability. The aspect of understanding the problem in cycle I was 82.86, increasing in cycle II to 94.29. The aspect of planning problem solving in cycle I was 63.17, increasing in cycle II to 81.59. The aspect of implementing the solution in cycle I was 56.67, increasing in cycle II to 78.41. The re-checking aspect in cycle I was 53.38, increasing in cycle II to 68.10. Furthermore, the results of the mathematical problem solving ability test of students after the provision of actions in cycle I were obtained as many as 22 students or 62.89% of students had achieved complete problem solving abilities with an average value of problem solving abilities in cycle I of 66.38. Furthermore, after the implementation of the actions in cycle II, the number of students who had achieved learning completeness was 30 students or 85.71% and the average class value was 80.48. Based on the descriptions above, it can be concluded that there was an increase in students' mathematical problem solving abilities through the application of the Problem Based Learning model assisted by GeoGebra.

Penelitian ini bertujuan untuk mengetahui bagaimana peningkatan kemampuan siswa dalam memecahkan masalah matematika pada materi dimensi tiga setelah diterapkan model Problem Based Learning berbantuan GeoGebra. Subjek dalam penelitian ini adalah siswa kelas XII MIPA 5 di SMA Negeri 5 Medan. Objek dalam penelitian ini adalah untuk meningkatkan kemampuan pemecahan masalah matematis siswa dengan menerapkan model Problem Based Learning (PBL) berbantuan GeoGebra. Instrumen penelitian yang digunakan adalah tes dan observasi. Penelitian ini adalah penelitian tindakan kelas dengan 2 siklus yang dilaksanakan pada semester ganjil tahun Pelajaran 2024/2025. Pada setiap akhir siklus diberikan tes untuk mengetahui peningkatan kemampuan pemecahan matematis siswa. Hadil tes menunjukkan bahwa terjadi peningkatan nilai rata-rata pada proses penyelesaian jawaban siswa dalam setiap indikator kemampuan pemecahan masalah. Aspek memahami masalah pada siklus I yaitu 82,86, meningkat pada siklus II menjadi 94.29. Aspek merencanakan penyelesaian masalah pada siklus I yaitu 63.17, meningkat pada siklus II menjadi 81,59. Aspek melaksanakan penyelesaian pada siklus I yaitu 56,67 meningkat pada siklus II menjadi 78,41. Aspek memeriksa kembali pada siklus I yaitu 53,38 meningkat pada siklus II menjadi 68,10. Selanjutnya, Hasil tes kemampuan pemecahan masaah matematis siswa setelah pemberian tindakan pada siklus I diperoleh sebanyak 22 siswa atau 62,89 % siswa telah mencapai ketuntasan kemampuan pemecahan masalah dengan nilai rata-rata kemampuan pemecahan masalah pada siklus I sebesar 66,38. Selanjutnya, setelah pelaksanaan tindakan pada siklus II, diperoleh jumlah siswa yang telah mencapai ketuntasan belajar sebanyak 30 siswa atau 85,71% dan nilai rata-rata kelas sebesar 80,48. Berdasarkan uraian-uraian diatas dapat disimpulkan bahwa terjadi peningkatan kemampuan pemecahan masalah matematika siswa melalui penerapan model Problem Based Learning berbantuan GeoGebra.
