Abstrak: Tujuan penelitian ini adalah untuk mengetahui efektivitas pembelajaran Problem Based Learning (PBL) dengan pendekatan Culturally Responsive Teaching (CRT) terhadap kemampuan pemecahan masalah peserta didik kelas VII materi pokok bangun ruang sisi datar di SMP Negeri 1 Semarang. Penelitian ini merupakan penelitian kuantitatif menggunakan metode eksperimen dengan bentuk true experimental design jenis pretest-posttest control group design. Pengambilan sampel menggunakan teknik cluster random sampling. Teknik pengumpulan data menggunakan tes. Teknik analisis data menggunakan nilai posttest dilakukan uji normalitas, uji homogenitas, dan uji perbedaan rata-rata. Hasil penelitian ini adalah rata-rata kemampuan pemecahan masalah kelas eksperimen lebih baik daripada rata-rata kemampuan pemecahan masalah kelas kontrol. Analisis uji-t menunjukkan bahwa rata-rata kemampuan pemecahan masalah kelas eksperimen adalah 88,618 dan kelas kontrol adalah 84,647. Dari hasil uji perbedaan rata-rata posttest menunjukkan bahwa nilai , maka  ditolak dan  diterima. Artinya, ada perbedaan kemampuan pemecahan masalah peserta didik yang diajar menggunakan model pembelajaran Problem Based Learning (PBL) dengan pendekatan Culturally Responsive Teaching (CRT) dan yang diajar menggunakan model pembelajaran konvensional. Dengan demikian, model PBL dengan pendekatan CRT ini dapat diimplementasikan secara efektif dalam proses pembelajaran. Kata Kunci: PBL, CRT, Bangun Ruang Sisi Datar.   Abstract : The aim of this research is to evaluate the effectiveness of Problem-Based Learning (PBL) integrated with a Culturally Responsive Teaching (CRT) approach on the problem-solving skills of seventh-grade students in the topic of solid geometry at SMP Negeri 1 Semarang. This quantitative research employs an experimental method with a true experimental design, specifically a pretest-posttest control group design. Cluster random sampling was used to select the sample. Data collection was conducted through testing. Data analysis involved normality tests, homogeneity tests, and mean difference tests on the posttest scores. The results of this research indicate that the average problem-solving ability of the experimental group is superior to that of the control group. T-test analysis reveals that the average problem-solving score of the experimental group is 88.618, compared to 84.647 for the control group. The mean difference test results show that  = 2.0175 is greater than  = 1.6683, leading to the rejection of  and acceptance of . This signifies a difference in the problem-solving abilities of students taught using the Problem-Based Learning (PBL) model with a Culturally Responsive Teaching (CRT) approach compared to those taught using conventional teaching methods. The findings show that the experimental class outperformed the control class in terms of problem-solving abilities. Therefore, the PBL model with a CRT approach can be effectively applied in the teaching process. Keywords: PBL, CRT, Solid Geometry.
