Abstract

This study aims to determine the effect of the Hypothetico-Deductive Reasoning method in Learning Cycle 7E on students' critical thinking skills. The design of this study is quasi-experimental with nonequivalent control group design and implemented at SMPN 1 Baureno with a population of all class VII. The sample used was 2 classes, namely class VII A as an experimental class and class VII B as a control class. The critical thinking ability test consist of 7 essay questions. It can be concluded that students' critical thinking skills are in good criteria with an average percentage of 72.61%.

Abstract

Pangan jajanan merupakan makanan dan minuman yang dijual oleh pedagang kaki lima di jalanan dan tempat-tempat umum lain yang langsung dimakan atau dikonsumsi kemudian tanpa pengolahan atau persiapan lebih lanjut. Oleh karena itu, keamanan pangan menjadi hal yang perlu diperhatikan. Salah satu penentu keamanan pangan adalah adanya zat-zat kimia berbahaya yang tidak boleh digunakan sebagai bahan tambahan pangan seperti formalin dan boraks. Penelitian ini bertujuan untuk mengidentifikasi adanya formalin dan boraks dalam pangan jajanan yang dijual di sekitar kabupaten Bangkalan. Pengambilan sampel dilakukan secara acak. Identifikasi dilakukan secara kualitatif dan kuantitatif. Identifikasi kualitatif boraks dengan menggunakan kertas kurkumin. Tes positif, jika terjadi perubahan warna dari kuning menjadi merah kecoklatan. Identifikasi kualitatif formalin menggunakan larutan PK. Tes positif, jika terjadi perubahan warna larutan PK dari pink menjadi memudar. Hasil identifikasi kuantitatif pangan jajanan menunjukkan bahwa presentase terbesar kandungan boraks ada pada tahu balut telur daerah Socah yaitu 213ppm dan presentase terbesar kandungan formalin ada pada kerupuk daerah Arosbaya yaitu 45ppm.
