Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh model Problem Based Learning (PBL) yang diintegrasikan dengan sejarah penemuan distilasi Jabir Ibn Hayyan terhadap kemampuan berpikir kritis mahasiswa. Penelitian menggunakan metode quasi experiment dengan desain Pretest-Posttest Non-equivalent Control Group Design. Sampel dipilih menggunakan teknik non-probability purposive sampling dan terdiri atas 31 mahasiswa pada kelas eksperimen serta 25 mahasiswa pada kelas kontrol. Kelas eksperimen memperoleh pembelajaran PBL terintegrasi sejarah kimia, sedangkan kelas kontrol memperoleh pembelajaran konvensional. data diperoleh melalui pretest dan posttest berupa 5 butir soal esai yang dinilai menggunakan Holistic Critical Thinking Scoring Rubric (HCTSR). Hasil penelitian menunjukkan bahwa rata-rata skor posttest kelas eksperimen sebesar 63,40 lebih tinggi dibandingkan kelas kontrol sebesar 53,20. Hasil perhitungan N-Gain pada kelas eksperimen berada pada kategori sedang, sedangkan kelas kontrol berada pada kategori rendah. Pengujian hipotesis menggunakan Mann–Whitney U menghasilkan nilai Asymp. Sig. (2-tailed) sebesar 0,016 (< 0,05), yang menunjukkan terdapat perbedaan yang signifikan antara kedua kelas. Oleh karena itu, dapat disimpulkan bahwa model Problem-Based Learning (PBL) yang diintegrasikan dengan sejarah kimia berpengaruh signifikan terhadap kemampuan berpikir kritis mahasiswa pada materi penemuan distilasi Jabir Ibn Hayyan. ***** This study aimed to analyze the effect of Problem-Based Learning (PBL) integrated with the historical context of Jabir Ibn Hayyan’s discovery of distillation on students’ critical thinking skills. The study employed a quasi-experimental method with a Pretest-Posttest Non-equivalent Control Group Design. The sample was selected using non-probability purposive sampling and consisted of 31 students in the experimental class and 25 students in the control class. The experimental class received PBL instruction integrated with the history of chemistry, while the control class received conventional instruction. Data were collected through pretest and posttest consisting of five essay questions assessed using the Holistic Critical Thinking Scoring Rubric (HCTSR). The results showed that the mean posttest score of the experimental class (63.40) was higher than that of the control class (53.20). The N-Gain score of the experimental class was categorized as moderate, whereas the control class was categorized as low. Hypothesis testing using the Mann–Whitney U test produced an Asymp. Sig. (2-tailed) value of 0.016 (< 0.05), indicating a significant difference between the two classes. Therefore, it can be concluded that Problem-Based Learning (PBL) integrated with the history of chemistry had a significant effect on students’ critical thinking skills in the topic of Jabir Ibn Hayyan’s discovery of distillation.
