Abstract
Penelitian ini bertujuan untuk mengetahui pengaruh praktikum berbasis green chemistry terhadap sikap peduli lingkungan siswa. Jenis penelitian yang digunakan adalah penelitian kuasi-eksperimen (quasi-experimental), dengan desain penelitian pretest-posttest control group design. Populasi pada penelitian ini adalah seluruh siswa kelas XI MIPA pada SMAN 1 Parakansalak tahun ajaran 2021/2022, yang terdiri dari empat kelas yaitu kelas XI MIPA 1, XI MIPA 2, XI MIPA 3 dan XI MIPA 4. Sampel dalam penelitian dipilih dengan menggunakan teknik convenience sampling. Kelas XI MIPA 4 dengan jumlah 19 siswa terpilih sebagai kelompok kontrol, dan XI MIPA 3 dengan jumlah 25 siswa terpilih sebagai kelompok eksperimen. Kelas XI MIPA 4 sebagai kelompok kontrol akan menggunakan metode praktikum kimia secara tradisional, sedangkan kelas XI MIPA 3 sebagai kelompok eksperimen akan menggunakan metode praktikum berbasis green chemistry. Data yang diperoleh dianalisis menggunakan uji independent samples t-test dan uji paired samples t-test. Hasil uji independent samples t-test (ɑ = 5%) untuk skor pretest dan posttest, menunjukkan nilai sig (2-tailed) diperoleh adalah 0,189 dan 0,037. Sedangkan hasil uji paired samples t-test (ɑ = 5%) untuk kelompok kontrol dan eksperimen, menunjukkan nilai sig (2-tailed) diperoleh adalah 0,349 dan 0,000. Data ini menunjukkan bahwa terdapat perbedaan signifikan untuk sikap peduli lingkungan antara kelompok kontrol dan eksperimen setelah melakukan praktikum titrasi asam basa dengan cara berbeda, dimana kelompok kontrol mengalami peningkatan skor sikap peduli lingkungan setelah melakukan praktikum titrasi asam basa dengan cara green chemistry. *******************This study aims to determine the influence of green chemistry-based practicum on students' environmental care attitudes. The type of research used is quasi-experimental research, with a pretest-posttest control group design. The population in this study was all students of class XI MIPA at SMAN 1 Parakansalak for the 2021/2022 school year, which consisted of four classes, namely class XI MIPA 1, XI MIPA 2, XI MIPA 3 and XI MIPA 4. The samples in the study were selected using convenience sampling techniques. Class XI MIPA 4 with a total of 19 students selected as the control group, and XI MIPA 3 with a total of 25 students selected as the experimental group. Class XI MIPA 4 as the control group will use the traditional chemistry practicum method, while class XI MIPA 3 as the experimental group will use the green chemistry-based practicum method. The data obtained were analyzed using independent samples t-test and paired samples t-test. The results of the independent samples t-test (ɑ = 5%) for pretest and posttest scores, showed that the sig (2-tailed) values obtained were 0.189 and 0.037. While the results of the paired samples t-test (ɑ = 5%) for the control and experimental groups, showed that the sig (2-tailed) values obtained were 0.349 and 0.000. This data shows that there are significant differences for environmental care attitudes between the control group and experiments after conducting acid-base titration practicum in different ways, where the control group experienced an increase in environmental care attitude scores after conducting acid-base titration practicum by green chemistry.*************************
