Penelitian ini menggunakan (quasi experiment) dengan desain posttest (non equivalent group design). Populasi dalam penelitian ini merupakan seluruh peserta didik kelas VII. Sampel penelitian, yaitu kelas VII F berjumlah 30 orang sebagai kelompok eksperimen dan kelas VII C berjumlah 28 orang sebagai kelompok kontrol yang diambil menggunakan teknik purposive sampling. Data keterampilan berpikir kritis diperoleh dari nilai posttest yang dianalisis dengan uji Independent Sample t-Test dengan bantuan aplikasi IBM SPSS Statistic Version 26. Hasil penelitian menunjukkan bahwa pada taraf signifikansi 0,05 didapatkan nilai Sig. (2-tailed) 0,000 {\ensuremath{<}} 0,05. Sehingga dapat disimpulkan bahwa terdapat pengaruh penggunaan model pembelajaran PjBL terhadap keterampilan berpikir kritis peserta didik materi pencemaran lingkungan.

This research employs a quasi-experimental design with a posttest (non-equivalent groups design). The population of this study comprises all seventh-grade students, with class VII F consisting of 30 individuals serving as the experimental group and class VII C comprising 28 individuals serving as the control group, selected using purposive sampling techniques. Data on critical thinking skills were obtained from posttest scores, which were analyzed using the Independent Sample t-Test with the assistance of IBM SPSS Statistics Version 26. The results indicate that at a significance level of 0.05, a Sig. (2-tailed) value of 0.000 was obtained, which is less than 0.05. Therefore, it can be concluded that there is a significant effect of the PjBL learning model on students' critical thinking skills regarding environmental pollution topics.
