Abstract
Critical thinking skills are very important to be mastered and developed by students, especially in the complex topic of thermochemistry. In addition, the integration of green chemistry is used in learning because the chemical practice process in high school still involves many hazardous materials. Through the PjBL model, this study aims to determine the process and determine the differences in results before and after the implementation of the green chemistry oriented project based learning model on students' critical thinking skills on the topic of thermochemistry. This model was chosen because it is able to actively involve students through practical activities based on real project designs at school, and this green chemistry integration is able to help students understand environmentally friendly sustainable living. This study uses a quantitative method with a pre-experimental design through a one-group pre-test post-test design. The subjects of this study were 35 students of grade XI-2 at SMAN 1 Kramatwatu with a purposive sampling technique. The instruments used include Teaching Modules, Student Worksheets (LKPD), observation sheets, PjBL assessment sheets and skill test questions. Data analysis was carried out in the descriptive test using Microsoft Excel applications while the inferential test used the SPSS application. The results showed that there were differences in students' critical thinking skills before and after implementing the project-based learning model. These results can be seen in the hypothesis test, where the sig. (2-tailed) value is 0,001 < 0,05, thus indicating that H0 is rejected and H1 is accepted. These results can be strengthened based on the test and non-test results, where based on the test results, the difference in students' pretest and posttest scores was 51,75%. Then based on the non-test results on the observation sheet, students' KBK achievement was 73,17% with "good" criteria and the PjBL assessment sheet was 86,11% with "very good" criteria.

| Additional Information: | Keterampilan berpikir kritis sangat penting untuk dikuasai dan dikembangkan oleh siswa khususnya pada topik termokimia yang bersifat kompleks. Selain itu, integrasi kimia hijau digunakan dalam pembelajaran karena proses praktik kimia di SMA masih banyak melibatkan bahan berbahaya. Melalui model PjBL, penelitian ini bertujuan untuk mengetahui proses dan mengetahui hasil perbedaan sebelum dan setelah diterapkan model project based learning berorientasi kimia hijau terhadap keterampilan berpikir kritis siswa pada topik termokimia. Model ini dipilih karena mampu melibatkan siswa secara aktif melalui kegiatan praktikum berdasarkan rancangan proyek nyata di sekolah, dan integrasi kimia hijau ini mampu membantu siswa dalam memahami kehidupan yang berkelanjutan yang ramah lingkungan. Penelitian ini menggunakan metode kuantitatif dengan rancangan pre-experimental melalui one group pre-test post-test design. Subjek penelitian ini adalah siswa kelas XI-2 di SMAN 1 Kramatwatu berjumlah 35 siswa dengan teknik purposive sampling. Intrumen yang digunakan meliputi Modul Ajar, LKPD, lembar observasi, lembar penilaian PjBL dan soal tes keterampilan. Analisis data yang dilakukan pada uji deskriptif menggunakan aplikasi Microsoft excel sedangkan uji inferensial menggunakan aplikasi SPSS. Hasil penelitian menunjukkan bahwa terdapat perbedaan keterampilan berpikir kritis siswa sebelum dan sesudah menerapkan model project based learning. Hasil ini dapat dilihat pada uji hipotesis, di mana nilai sig.(2-tailed) sebesar yaitu sebesar 0,001 < 0,05, sehingga menunjukkan bahwa H0 ditolak dan H1 diterima. Hasil ini dapat diperkuat berdasarkan hasil tes dan non tes, di mana berdasarkan hasil tes diperoleh selisih nilai pretest dan posttest siswa sebesar 51,75%. Kemudian berdasarkan hasil non tes pada lembar observasi ketercapaian KBK siswa sebesar 73,17% dengan kriteria “baik” dan lembar penilaian PjBL sebesar 86,11% dengan kriteria “sangat baik”. | |||||||||
