Abstract

This research explores using the Predict, Observe, and Explain (POE) model to enhance the learning process in elementary schools, particularly in biology lessons. The study conducted at SMP Berea Tondano with class VII focuses on how the POE model affects student understanding and engagement, specifically in classifying living organisms. A classroom action research (CAR) approach was employed in two cycles, each involving planning, action, observation, and reflection. Nine students from class VII participated in the study. Data were collected through observations, student activity sheets, and tests at the end of each cycle to evaluate the impact of the POE model on learning outcomes and student engagement. The research findings revealed significant improvements in student engagement and learning outcomes across the two cycles. In the first cycle, 55.56% of students achieved the learning goals, which increased to 88.89% in the second cycle. Similarly, student activity levels rose from 35.71% in the first cycle to 78.57% in the second cycle, reflecting greater participation and motivation. The study concludes that the POE model effectively enhances student learning outcomes and promotes active engagement. By involving students in prediction, observation, and explanation, the POE model aids in better understanding and retention of biological concepts. Further research is suggested to explore its application in other subjects and educational contexts.

Abstract

Produk tahu sudah lama menjadi makanan pokok masyarakat Indonesia, terlebih khusus di Kota Manado. Selain harganya murah produk tahu juga sangat banyak dijumpai di tempat-tempat perbelanjaan tradisional maupun swayalan. Tahu memiliki banyak manfaat sebagai sumber protein pengganti dari ikan dan daging. Pada waktu pembuatan tahu biasa kita rendam dengan air terlebih dahulu, karena tahu banyak mengandung protein air rendamannya harus higienis, karena jika tidak higienis akan berpotensi sebagai sarang bakteri pembawa penyakit. Penelitian ini mengenai identifikasi bakteri E.coli pada air rendaman tahu yang diperoleh dari Pasar Bersehati Kota Manado. Air rendaman tahu sudah banyak diteliti, namun belum banyak pengujiannya menggunakan Uji Sitrat, Uji SIM, Uji MR-VP. Penelitian ini bertujuan untuk mengidentifikasi bakteri E.coli di rendaman air tahu. Rancangan penelitian yang digunakan adalah rancangan penelitian deskriptif, mikroskopik, pewarnaan gram, uji biokimia. Hasil penelitian menunjukkan bahwa air yang diambil dari 5 sampel menunjukkan adanya 5 isolat bakteri patogen. Berdasarkan media tumbuh bakteri hanya 3 isolat yang teridentifikasi bakteri E.coli melalui isolasi, pengenceran, pewarnaan gram, dan uji biokimia. Sedangkan 2 sampel tidak teridentifikasi bakteri E.coli. 5 sampel yang telah diteliti ternyata hanya sampel 1,2, dan 4 yang teridentifikasi bakteri E.coli sedangkan sampel 3 dan 5 tidak teridentifikasi bakteri E.coli.
