Penelitian ini dilatarbelakangi oleh rendahnya hasil belajar siswa pada materi larutan penyangga. Oleh karena itu diterapkan model pembelajaran inkuiri terbimbing berorientasi green chemistry yang bertujuan untuk meningkatkan hasil belajar dan mengetahui respon siswa pada materi larutan penyangga di MAN 1 Banda Aceh Tahun Pelajaran 2018/2019. Populasi sampel pada penelitian ini adalah seluruh siswa kelas XI IPA MAN 1 Banda Aceh. Pengambilan sampel menggunakan teknik purposive sampling. Sampel penelitian ini adalah kelas XI IPA3 sebagai kelas eksperimen dan XI IPA4 sebagai kelas kontrol. Pengumpulan data menggunakan 14 soal pilihan ganda beralasan. Analisis data hasil belajar menggunakan perhitungan N-gain dan uji t sedangkan respon siswa menggunakan persentase. Hasil penelitian menunjukkan rata-rata nilai postes kelas eksperimen sebesar 77% sedangkan kelas kontrol sebesar 54%. Skor N-gain kelas eksperimen sebesar 73% termasuk kategori tinggi sedangkan kelas kontrol sebesar 44% termasuk kategori sedang. Hasil analisis data menggunakan uji hipotesis (uji t) yang menunjukkan nilai thit ttabel (7,6121,993) maka terdapat perbedaan yang signifikan sehingga dapat disimpulkan bahwa model inkuiri terbimbing berorientasi green chemistry dapat meningkatkan hasil belajar siswa. Siswa juga memberikan respon positif terhadap model pembelajaran ini.

“…Previous research shows that chemical concepts taught in the context of green chemistry allow students to make connections with their local economic, environmental, and societal context; these connections are thought to underlie the advanced conceptual understanding that students develop compared to their peers who are instructed in the same concepts but in a traditional teacher-centered approach (Karpudewan et al, 2012a(Karpudewan et al, , 2012b(Karpudewan et al, , 2012cKarpudewan et al, 2015). In these studies, the green chemistry curriculum resulted not only in conceptual gains but also gains in other areas.…”

“…Research shows that students tend to have a variety of misunderstandings concerning acids and bases (Demircioglu et al, 2005) often despite and perhaps because of teaching (Chiu, 2007;Artdej et al, 2010). green chemistry experiments and activities) that fosters debate over controversial issues also revealed an enhanced student understanding of chemistry concepts (Karpudewan et al, 2015). A study investigating a socio-constructivist approach (e.g.…”

In a world where environmental degradation is taking on alarming levels, understanding, and acting to minimize, the individual environmental impact is an important goal for many science educators. In this study, a green chemistry curriculum—combining chemistry experiments with everyday, environmentally friendly substances with a student-centered approach that includes student–student discussion—was tested for its potential to increase the understanding of acid–base concepts and argumentative skills. A quasi-experimental design was chosen intended to take into account teacher/school nested effects. The study involved three classes of 150 16 year old Form Four students (1 experimental,N= 50; 2 control,N= 100) from two Schools A and B serving students from the same sociocultural and economic backgrounds taught by two teachers (Teacher A in School A taught 1 experimental and 1 control; Teacher B in School B taught 1 control). An ANCOVA with a pre-test as a covariate showed a statistically significant treatment effect as measured by an acid–base concept understanding test. Additionally, qualitative analysis of an Argumentation Skill Test (AST) shows that the experimental students used higher levels of argumentation skills following treatment than their peers in the two control classes. Implications are discussed for integrating green chemistry into the secondary school chemistry curriculum to teach the content on acid–base and green chemistry as a tool to assist the construction of arguments.

“…Various studies relating to the application of green chemistry as an effort for environmental sustainability have been carried out [12,13,14,15], but the phenomenon of environmental crisis is still being found, especially with regard to chemistry. This shows that the knowledge of green chemistry for chemical industry practitioners has not been implemented or understood yet.…”

The importance of improving the quality of learning in schools is more and more recognized. Now day Green Chemistry is recommended in teaching chemistry as an effort to foster students' caring attitudes towards the environment. On the other hand, improving teaching quality through a lesson study has been done a lot. This paper contributes a solution to the problem of improving the quality of chemistry teaching that fosters students' caring attitudes towards the environment. The integration of the principles of green chemistry through the application of the principles of Lesson Study learning community that allows the principles of green chemistry to be understood and applied by students in their daily lives results in a Teaching model called Green Chemistry Learning Comprehensive by Collaborative and Collegialities (GCLC2C) that has been developed and validated.
