ABSTRAK Perilaku peduli lingkungan merupakan representasi dari pengetahuan, perilaku, dan keterampilan yang dipelajari siswa melalui pembelajaran kimia untuk memecahkan masalah di sekitarnya. Siswa dinyatakan peduli lingkungan jika dapat menerapkan konsep-konsep kimia yang telah diketahuinya untuk memecahkan masalah dan mencegah kerusakan lingkungan. Perilaku peduli lingkungan siswa yang dibangun didukung dengan implementasi Problem Based Learning (PBL) dengan pendekatan Green Chemistry. Penelitian ini bertujuan untuk mengetahui apakah terjadi peningkatan perilaku peduli lingkungan pada implementasi PBL berorientasi Green Chemistry pada materi indikator asam basa alami. Metode penelitian yang digunakan adalah Pre Eksperimental dengan desain One Group Pretest Posttest. Subjek dari penelitian ini berjumlah 30 siswa di salah satu SMA Swasta Kota Bandung. Instrumen penelitian yang digunakan adalah lembar observasi keterlaksanaan pembelajaran dan jawaban LKS, angket perilaku peduli lingkungan serta soal tes penguasaan konsep. Hasil penelitian menunjukkan bahwa: 1) Persentase keterlaksanaan pembelajaran PBL berorientasi Green Chemistry sebesar 82,1 yang dikategorikan baik dan berdasarkan jawaban siswa di LKS memperoleh skor rata-rata 61 yang dikategorikan baik; 2) Adanya perbedaan yang signifikan rata-rata skor perilaku peduli lingkungan siswa setelah implementasi PBL berorientasi Green Chemistry dibandingkan sebelum implementasi, dan 3) Adanya perbedaan yang signifikan rata-rata skor penguasaan konsep siswa setelah implementasi PBL berorientasi Green Chemistry dibandingkan sebelum implementasi. ABSTRACT Environmental care behavior is a representation of the knowledge, behavior, and skills that students learn through learning chemistry to solve problems around them. Students are declared to care about the environment if they can apply the chemical concepts they already know to solve problems and prevent environmental damage. The students' environmental care behavior that is built is supported by the implementation of Problem Based Learning (PBL) with a Green Chemistry approach. This study aims to determine whether there is an increase in environmental care behavior in the implementation of Green Chemistry-oriented PBL on natural acid-base indicator materials. The research method used is Pre Experimental with One Group Pretest Posttest design. The subjects of this study amounted to 30 students in one of the private high schools in Bandung. The research instrument used was an observation sheet on the implementation of learning and student worksheet answers, environmental care behavior questionnaire and concept mastery test questions. The results showed that: 1) The percentage of implementation of Green Chemistry-oriented PBL learning was 82.13, which was categorized as good and based on students' answers in LKS obtained an average score of 61 which was categorized as good; 2) There is a significant difference in the average score of students' environmental care behavior after implementing Green Chemistry-oriented PBL compared to before implementation, and 3) There is a significant difference in the average score of students' concept mastery after implementing Green Chemistry-oriented PBL compared to before implementation.
