Abstract

Salah satu materi biologi yang dapat disampaikan dengan baik melalui kegiatan pengamatan adalah materi Eubacteria. Kegiatan pengamatan spesimen bakteri pada LKS dapat ditunjang dengan adanya media preparat bakteri. Tujuan dari penelitian ini adalah untuk menghasilkan LKS pengamatan dan media preparat bakteri, mendeskripsikan validitas LKS dan media berdasarkan hasil validasi ahli, mendeskripsikan efektifitas LKS dan media berdasarkan ketuntasan indikator dan respons siswa, serta mendeskripsikan kepraktisan LKS dan media berdasarkan aktivitas siswa. Penelitian ini merupakan penelitian pengembangan yang mengacu pada model Research & Development. Bakteri yang digunakan dalam penelitian ini adalah bakteri asam laktat dari dua larutan fermentasi yang berbeda serta bakteri Escherichia coli dan Staphylococcus aureus. Uji coba terbatas dilaksanakan di SMAN 1 Gedangan Sidoarjo pada bulan Agustus 2016. Hasil validasi LKS dan media memperoleh kelayakan sebesar 94,78% dan 95,24% dengan interpretasi sangat layak. LKS dan media preparat bakteri dinyatakan sangat efektif ditinjau dari ketuntasan hasil belajar sebesar 93,33%, respons siswa sebesar 98,34% dan 98,96%. LKS pengamatan dan media preparat dinyatakan sangat praktis ditinjau dari aktivitas siswa sebesar 98,54%. Berdasarkan hal tersebut dapat disimpulkan bahwa LKS materi Eubacteria dan media preparat bakteri layak dari segi validitas, keefektifan, dan kepraktisan. Kata Kunci: Lembar Kegiatan Siswa, Media Preparat Bakteri, Validitas, Kepraktisan, dan Keefektifan

Abstract

Traditional food processing practices often contain implicit scientific knowledge that can be systematically analyzed and explained using modern science. This study examines the scientific knowledge embedded in the traditional preparation of Wadi, a fermented fish product of the Dayak and Banjar communities. The research aims to identify and describe forms of scientific knowledge represented in each stage of the Wadi-making process. This study employed a qualitative descriptive method using documentation analysis. Data were collected from selected written and visual sources that clearly describe the stages of Wadi production. The data were analyzed by mapping traditional practices to scientific concepts in food science. The results indicate that the preparation of Wadi embodies multiple forms of scientific knowledge, including osmosis in the salting process, salt-based preservation through microbial inhibition, lactic acid fermentation, moisture control, and biochemical transformations such as protein hydrolysis. These findings demonstrate that traditional culinary practices are not merely cultural activities but also reflect systematic scientific knowledge consistent with principles of microbiology, biochemistry, and food preservation. In conclusion, the scientific knowledge identified in the making of Wadi has strong potential to support contextual and culturally relevant science learning by connecting everyday practices with formal scientific concepts.
