This study was motivated by the need to implement a learning model that can actively engage students in problem-solving activities and utilize contextual and interactive learning media in ecosystem learning. This study aimed to determine the effect of the Problem Based Learning (PBL) model assisted by Google Sites integrated with QuizWhizzer on the learning outcomes of seventh-grade students at SMP Negeri 34 Samarinda. This study employed a quasi-experimental method with a nonequivalent control group design. The sample consisted of an experimental class that received learning through the PBL model assisted by Google Sites integrated with QuizWhizzer and a control class that received conventional learning. Data were collected using learning outcome tests in the form of pretests and posttests and were analyzed using the Mann-Whitney test and N-Gain. The Mann-Whitney test of the pretest scores showed an Asymp. Sig. (2-tailed) value of 0.114 > 0.05, indicating no significant difference in initial abilities between the two classes. The hypothesis test of the posttest scores yielded an Asymp. Sig. (2-tailed) value of 0.079 > 0.05, indicating no significant difference in learning outcomes between the two classes. The mean N-Gain score was -0.053 for the experimental class, categorized as a decrease, and 0.051 for the control class, categorized as low. Thus, the implementation of PBL assisted by Google Sites integrated with QuizWhizzer did not show a significant effect on students’ learning outcomes. These findings indicate the need to consider students’ readiness, learning management, the use of technology-based media, and students’ engagement in group discussions. ABSTRAK Penelitian ini dilatarbelakangi oleh perlunya penerapan model pembelajaran yang dapat melibatkan peserta didik secara aktif dalam pemecahan masalah serta penggunaan media pembelajaran yang kontekstual dan interaktif pada materi ekosistem. Penelitian ini bertujuan untuk mengetahui pengaruh model Problem Based Learning dengan media Google Sites terintegrasi QuizWhizzer terhadap hasil belajar peserta didik kelas VII SMP Negeri 34 Samarinda. Penelitian ini menggunakan jenis penelitian quasi experiment dengan desain nonequivalent control group. Sampel penelitian terdiri atas kelas eksperimen yang memperoleh pembelajaran menggunakan PBL dengan media Google Sites terintegrasi QuizWhizzer dan kelas kontrol yang memperoleh pembelajaran konvensional. Data dikumpulkan menggunakan tes hasil belajar berupa pretest dan posttest, kemudian dianalisis menggunakan uji Mann-Whitney dan N-Gain. Hasil uji Mann-Whitney terhadap nilai pretest menunjukkan nilai Asymp. Sig. (2-tailed) sebesar 0,114 > 0,05, sehingga tidak terdapat perbedaan kemampuan awal yang signifikan antara kedua kelas. Hasil uji hipotesis terhadap nilai posttest memperoleh nilai Asymp. Sig. (2-tailed) sebesar 0,079 > 0,05, sehingga tidak terdapat perbedaan hasil belajar yang signifikan antara kedua kelas. Rata-rata N-Gain kelas eksperimen sebesar -0,053 dengan kategori terjadi penurunan, sedangkan kelas kontrol sebesar 0,051 dengan kategori rendah. Dengan demikian, penerapan PBL dengan media Google Sites terintegrasi QuizWhizzer belum menunjukkan pengaruh yang signifikan terhadap hasil belajar peserta didik. Hasil tersebut menunjukkan perlunya memperhatikan kesiapan peserta didik, pengelolaan pembelajaran, penggunaan media berbasis teknologi, dan keterlibatan peserta didik dalam diskusi kelompok.
