Abstract
Abstrak
Penelitian ini bertujuan untuk mengetahui pengaruh model Problem Based Learning (PBL) berbantuan Educaplay terhadap kemampuan pemecahan masalah matematis siswa kelas VII SMP Negeri 1 Padangan pada materi aljabar. Penelitian ini merupakan penelitian kuantitatif. Desain penelitian yang digunakan adalah pretest-posttest control group design. Populasi penelitian adalah seluruh siswa kelas VII SMP Negeri 1 Padangan, sedangkan sampel penelitian terdiri atas kelas VII D sebagai kelas kontrol dan kelas VII E sebagai kelas eksperimen yang dipilih menggunakan teknik random sampling Instrumen penelitian berupa kemampuan pemecahan masalah matematis berbentuk 20 soal pilihan ganda. Teknik analisis data menggunakan uji normalitas, uji homogenitas, uji keseimbangan dan uji hipotesis menggunakan uji-t. Hasil penelitian menunjukkan bahwa terdapat pengaruh model Problem Based Learning (PBL) berbantuan web Educaplay terhadap kemampuan pemecahan masalah matematis siswa. Hal ini terlihat dari hasil posttest kelas eksperimen yang lebih tinggi dibandingkan kelas kontrol. Dengan demikian, model Problem Based Learning (PBL) berbantuan web Educaplay digunakan sebagai alternatif pembelajaran untuk meningkatkan kemampuan pemecahan masalah matematis siswa.

Abstract
This study aims to determine the effect of the Problem-Based Learning (PBL) model assisted by the Educaplay website on the mathematical problem-solving abilities of seventh-grade students at SMP Negeri 1 Padangan in algebra. This research is quantitative. The research design used a pretest-posttest control group design. The study population was all seventh-grade students at SMP Negeri 1 Padangan, while the sample consisted of class VII D as the control class and class VII E as the experimental class, selected using a random sampling technique. The research instrument was a mathematical problem-solving ability test in the form of 20 multiple-choice questions. Data analysis techniques used normality tests, homogeneity tests, and balance tests, and hypothesis testing using t-tests. The results showed that the Problem-Based Learning (PBL) model assisted by the Educaplay website influenced students' mathematical problem-solving abilities. This was evident from the posttest results of the experimental class, which were higher than those of the control class. Thus, the Problem-Based Learning (PBL) model assisted by the Educaplay website can be used as an alternative learning method to improve students' mathematical problem-solving abilities.
