Abstract

This research is motivated by the low cognitive learning outcomes and environmental awareness among students due to ecosystem topics traditionally being delivered in an abstract and theoretical manner. This study, entitled "Pemanfaatan Media Terrarium dalam Pembelajaran Ilmu Pengetahuan Alam untuk Meningkatkan Pemahaman Ekosistem dan Kesadaran Lingkungan Siswa," aims to examine the implementation of the project-based learning model utilizing terrarium media to improve students' cognitive achievement and environmental awareness. The method employed is classroom action research based on the Kemmis and McTaggart model, conducted over two cycles. The results demonstrate an increase in the average cognitive score from 52.25 to 84.50, with the final classical completeness reaching 91.30 percent and a Normalized Gain (N-Gain) value categorized as moderate. Meanwhile, the average score for students' environmental awareness rose from 50.73 percent to 82.21 percent, meeting the criteria for "highly conscious". In conclusion, the implementation of the project-based learning model with terrarium media is proven effective in significantly increasing cognitive learning success while simultaneously fostering students' environmental awareness.

Abstract

Bekatul merupakan hasil samping penggilingan padi yang seringkali hanya diangga limbah. Padahal di dalamnya terdapat kandungan yang dapat dimanfaatkan seperti selulosa. Hidrolisis selulosa oleh enzim selulase akan menghasilkan senyawa glukosa. Enzim selulase dapat diperoleh dari berbagai sumber, salah satunya bakteri Bacillus sp. Tujuan dari penelitian ini adalah mengetahui pengaruh konsentrasi substrat bekatul dan suhu inkubasi terhadap aktivitas enzim selulase Bacillus sp. Uji aktivitas enzim selulase pada substrat bekatul dilakukan dengan konsentrasi 0,5%; 1,0%; 1,5% dan suhu inkubasi 30°C, 40°C, 50°C menggunakan metode DNS (3,5-Dinitrosalicylic acid). Data yang diperoleh kemudian dianalisis dengan Two Way ANOVA dan uji lanjut Beda Nyata Terkecil pada P<0,05. Hasil penelitian menunjukkan bahwa tidak terdapat pengaruh signifikan yang diberikan oleh interaksi antara konsentrasi substrat bekatul dengan suhu inkubasi terhadap aktivitas enzim selulase dari Bacillus sp. Namun, terdapat pengaruh yang diberikan oleh masing-masing variasi perlakuan konsentrasi substrat dan suhu inkubasi terhadap aktivitas enzim. Aktivitas enzim selulase tertinggi terhadap substrat bekatul diperoleh pada variasi perlakuan konsentrasi substrat 1,5% dan suhu inkubasi 50°C yaitu 0,0185 U/mL.
