Description acids and bases topics. Quasy experiment was chosen as research method with posttest only group design. The research population was students of XI IPA 1 and XI IPA 2 in SMA Negeri 26 Jakarta. The sample was established using the purposive sampling technique by choosing two classes as experiment class and control class. The experiment class was taught by using the Blended-Problem Based Learning model, while the control class was taught by using Blended-Explicit Instruction. The data were collected by using critical thinking skill questions. The data analysis technique used independent sample t test. The result showed that the experiment class’s mean was 68,306, while the control class was 58,611. The hypothesis was obtained by value of tcalculate (3,454) > ttable (1,667) with significant level is 0,05. So, it can be concluded that there was positive effect of Blended-Problem Based Learning model on students’ critical thinking skill in acids and bases topics.

Penelitian ini bertujuan untuk mengetahui pengaruh penerapan model pembelajaran Blended-Problem Based Learning terhadap kemampuan berpikir kritis peserta didik pada materi Asam dan Basa. Kuasi eksperimen dipilih sebagai metode penelitian dengan desain posttest only group. Populasi dalam penelitian merupakan peserta didik kelas XI IPA 1 dan XI IPA 2 SMA Negeri 26 Jakarta. Penentuan sampel menggunakan teknik purposive sampling, dengan memilih dua kelas yang dijadikan sebagai kelas eksperimen dan kelas kontrol. Kelas eksperimen diterapkan pembelajaran menggunakan model Blended-Problem Based Learning, sedangkan kelas kontrol diterapkan pembelajaran menggunakan model Blended-Explicit Instruction. Pengumpulan data menggunakan tes soal kemampuan berpikir kritis materi asam dan basa. Data dianalisis menggunakan statistik uji t sampel independen. Hasil penelitian menunjukkan bahwa nilai rata-rata posttest kelas eksperimen sebesar 68,306 dan kelas kontrol sebesar 58,611. Hasil pengujian terhadap hipotesis diperoleh dengan nilai thitung (3,454) > ttabel (1,667) pada taraf signifikan 0,05. Dengan demikian, dapat disimpulkan bahwa terdapat pengaruh positif pada penerapan model pembelajaran Blended-Problem Based Learning terhadap kemampuan berpikir kritis peserta didik pada materi Asam dan Basa.
