Jenis ini adalah penelitian tindakan kelas. Penelitian ini bertujuan untuk mengetahui perbedaan yang signifikan antara kelas siswa yang dibelajarkan melalui model Problem Based Learning berbantuan aplikasi quizizz dan kelas siswa yang dibelajarkan melalui model konvensional. Penelitian ini merupakan penelitian eksperimen semu dengan desain penelitiannya adalah non-equivalent post-test control group design. Populasi dalam penelitian ini siswa kelas V SD gugus VII Kecamatan Ubud sebanyak 104 orang siswa. Untuk menentukan sampel digunakan teknik random sampling. Sampel dalam penelitian ini adalah siswa kelas V SD Negeri 2 Sayan yang berjumlah 28 orang sebagai kelas eksperimen dan SD Negeri 1 Sayan yang berjumlah 22 orang sebagai kelas kontrol. Pengumpulan data kemampuan memecahkan masalah dilakukan dengan metode tes, yaitu tes kemampuan memecahkan masalah, dengan jenis tes essai. Data selanjutnya dianalisis menggunakan analisis statistik uji-t. Hasil penelitian menunjukkan, bahwa terdapat perbedaan yang signifikan kemampuam memecahkan masalah antara kelas siswa yang dibelajarkan melalui model problem based learning berbantuan aplikasi quizizz dan siswa yang dibelajarkan melalui pembelajaran konvensional. Hal ini terbukti dari hasil analisis dengan menggunakan uji-t diperoleh thitung = 10,858 > ttabel (α=0,05,50) = 1,675 dan didukung dengan perbedaan rata-rata kemampuan memecahkan masalah antara kelas eksperimen dan kelas kontrol yaitu = 62,11 > = 46,68. Dengan demikian dapat disimpulkan, bahwa model Problem Based Learning berbantuan aplikasi quizizz berpengaruh terhadap kemampuan memecahkan masalah siswa di kelas V SD Gugus VII Kecamatan Ubud.

Abstract
This type was classroom action research. This study aims to determine the significant difference between the class of students who are taught through the Problem Based Learning model assisted by the Quizizz application and the class of students who are taught through the conventional model. This research was a quasi-experimental research with a non-equivalent post-test control group design. The population in this study were 104 students in the fifth grade of SD cluster VII, Ubud District. To determine the sample used random sampling technique. The sample in this study was the fifth grade students of SD Negeri 2 Sayan, totaling 28 people as the experimental class and SD Negeri 1 Sayan, amounting to 22 people as the control class. The data collection of problem-solving abilities was carried out by the test method, namely the problem-solving ability test, with the type of essay test. The data were then analyzed using t-test statistical analysis. The results showed that there was a significant difference in problem-solving abilities between classes of students who were taught through a problem-based learning model assisted by the Quizizz application and students who were taught through conventional learning. This is evident from the results of the analysis using the t-test obtained tcount = 10,858 > ttable (α=0,05,50) = 1,675 and is supported by the difference in the average problem-solving ability between the experimental class and the control class, namely X = 62, 11 > X = 46.68. Thus, it can be concluded that the Problem Based Learning model assisted by the Quizizz application has an effect on the problem solving ability of students in class V SD Cluster VII, Ubud District.
