This paper is a call for teachers to initiate measures in improving the quality of high school chemistry education in the Philippines and that is by going back to practical laboratory work. The experiment presented in this paper is a proof to the possibility of tailor-made experiments that integrate principles of green chemistry. Integrating green...

... There have been some modifications implemented to meet the green experiment's standards. Different tailor-made experiments integrating principles of green chemistry have been developed in emerging Asian countries, including (i) replacing the current non-beneficial and harmful experiments and utilizing environmentally benign raw materials (Santos & Guidote, 2015;Wang et al., 2020;Kiwfo et al., 2021); (ii) designing Context-Based Green Chemistry Experiments (CBGCEs (Karpudewan & Mathanasegaran, 2018;Bodner, 2015); (iii) popularizing microscale chemistry experiments or known as Small Scale Chemistry (SSC) (Tantayun, 2015;Wang et al., 2018;Listyarini et al., 2019;Zhou, 2019); (iv) developing of laboratory manual ; (v) emphasizing accreditation of policies, rules, and regulations regarding chemical safety in every green chemistry research laboratory (Tantayanon, 2015). ...
... For instance, the guava leaf extracts were transformed into a ready-touse green reagent powder. They were utilized as a natural-reagent assay kit for determining iron (Santos & Guidote, 2015;Kiwfo et al., 2021), molasses as glucose to produce ethanol, producing Br2 in situ while brominating alkenes with HBr and H 2 O 2 (Karpudewan, 2020). They also utilized lauric acid and Vitamin C instead of hazardous substances such as naphthalene, sodium thiosulphate, and corncobs as raw materials to synthesize biodiesel, ethanol, and sunscreen (Zhou et al., 2019). ...
This paper aims to investigate and synthesize literature exploring the current state of Green Chemistry Education (GCE) in the emerging economies in Asia to determine what has been done and the continuing projects for the promotion of Green Chemistry (GC). The researchers used the integrative literature review approach to examine qualitative, quantitative, and mixed methods and empirical and theoretical literature related to GCE. This approach includes (a) problem identification, (b) search for structured literature, (c) data evaluation, (d) data analysis , and (e) presentation of findings. Published studies revealed that most initiatives in integrating GC principles in emerging economies in Asia focused on the secondary and tertiary levels but not graduate studies and non-chemistry-related courses. Most of its progress has been observed in Organic Chemistry and General Chemistry. Results also revealed that the barriers that hampered integrating GCE are pedagogical resources (insufficient or unavailability of time, financial and technological resources) and pedagogical content knowledge (misconceptions about GC, lack of expertise, and the need to update technical knowledge). It can be concluded that even in the initial stage of implementation of green chemistry education in the emerging economies in Asia, and despite numerous documented barriers, proactive efforts are being made by numerous institutions and even individuals who are tenaciously advocating green chemistry. These efforts are enriched through various educational programs , learner-centered pedagogical practices, and strategies that enhance teachers' and students' content knowledge and skills. Finally, economics is a major factor in determining a country's state of Green Chemistry as the economic condition can be credited to outstanding or dismal achievements.
... Siswa yang memahami konsep akan mengingat konsep tersebut dalam jangka waktu yang lama sehingga dapat meningkatkan hasil belajar (Ismail, 2016). Siswa juga lebih berpartisipasi aktif dalam kegiatan praktikum sehingga menciptakan pembelajaran kimia yang lebih menarik, menyenangkan dan lebih bermakna (Santos & Guidote, 2015). Selain itu, Nisa, dkk. ...
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.
