Oleh karena itu, kegiatan belajar peserta didik harus senantiasa diarahkan tidak hanya dalam penguasaan konsep-konsep semata, namun juga pada peningkatan kemampuan berpikir peserta didik, khususnya kemampuan berpikir kritis. Hakikatnya, berpikir kritis merupakan kemampuan untuk mempertimbangkan informasi yang diperoleh dari berbagai sumber, kemudian mengolahnya secara kreatif dan logis, menilai kebenarannya, menganalisis, dan menarik kesimpulan akhir, sehingga informasi tersebut dapat dipertahankan kebenarannya. Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran Learning Cycle 7E terhadap kemampuan berpikir kritis peserta didik pada konsep pencemaran lingkungan di kelas VII SMP Negeri 2 Kota Tasikmalaya. Penelitian ini dilaksanakan pada bulan April Mei 2018 di SMP Negeri 2 Kota Tasikmalaya. Metode eksperimen yang digunakan adalah true experimental dengan populasi seluruh kelas VII SMP Negeri 2 Kota Tasikmalaya sebanyak 11 kelas dengan jumlah siswa 352 orang. Sampel diambil dengan menggunakan teknik cluster random sampling sebanyak 2 kelas, yaitu kelas VII-J sebagai kelas eksperimen dan kelas VII-I sebagai kelas kontrol. Instrumen yang digunakan untuk mengukur kemampuan berpikir kritis berupa soal uraian dengan jumlah 17 butir soal. Teknik analisis data yang digunakan yaitu menggunakan uji ANOVA dengan taraf signifikansi (α) 0,05. Hasil penelitian menunjukkan bahwa Learning Cycle 7E berpengaruh terhadap kemampuan berpikir kritis peserta didik dengan skor rata-rata 38,03, dibandingkan dengan kelas kontrol dengan skor rata-rata 34,80.

To reduce Indonesia's dependence on biomaterials imports in the field of biomedicine, it can be done through the engineering of operating yarn production absorbed from Indonesia's natural resources. Poly Lactic Acid (PLA) is a polymer that is widely applied as a biomaterial in biomedical fields such as operating threads. In this research, absorbable suture was made from poly lactic acid poly polymer blend from water hyacinth with natural glucomannan polymer of iles-iles.
