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.

Abstract

Abstrak. Penelitian ini bertujuan untuk mendokumentasikan keanekaragaman jenis tumbuhan anggota Pteridophyta pada area lahan gambut di kawasan kampus Universitas Palangka Raya. Hasil penelitian selanjutnya dimanfaatkan untuk menunjang kegiatan praktikum mata kuliah Botani Tumbuhan Rendah. Penelitian ini dilaksanakan pada bulan April-Agustus 2005 di kawasan kampus Universitas Palangka Raya. Metode penelitian menggunakan metode deskriptif. Pengumpulan data dilakukan dengan teknik survei eksploratif, yaitu menjelajahi/menelusuri secara langsung semua area-area sampling yang telah ditentukan di wilayah populasi di kawasan kampus UPR. Analisis data secara deskriptif, dengan cara mengidentifikasi, mendeskripsi, dan mengklasifikasi, serta mendokumentasi semua spesimen tumbuhan paku angota divisi Pteridophyta yang ditemukan. Hasil penelitian menemukan 25 jenis tumbuhan anggota Pteridophyta pada vegetasi lahan gambut di kawasan kampus Universitas Palangka Raya, yaitu: Cyclosorus aridus Ching., Cyclosorus sp., Stenochlaena palustris Bedd., Nephrolepis biserrata Schott., Nephrolepis hirsutula, Pteris ensiformis Burm., Blechnum sp., Pteridium aquilinum Underw., Gleichenia linearis, Davallia denticulata (Burm.f.) Mett., Phymatosorus scolopendria (Burm.f.) Pic.

The results will then be used to support laboratory activities in the Lower Plant Botany course. This research was conducted from April to August 2005 on the University of Palangka Raya campus. The research method used was descriptive. Data collection was conducted using an exploratory survey technique, which involved directly exploring all predetermined sampling areas within the population area of ​​the UPR campus. Descriptive data analysis, namely by identifying, describing, and classifying, as well as documenting all specimens of ferns belonging to the Pteridophyta division that were found. The research results found 25 types of plants belonging to the Pteridophyta in peatland vegetation in the Palangka Raya University campus area, namely: Cyclosorus aridus Ching., Cyclosorus sp., Stenochlaena palustris Bedd., Nephrolepis biserrata Schott., Nephrolepis hirsutula, Pteris ensiformis Burm., Blechnum sp., Pteridium aquilinum Underw., Gleichenia linearis, Davallia denticulata (Burm.f.) Mett., Phymatosorus scolopendria (Burm.f.) Pic. Serm., Pyrrosia lanceolata (L) Farw., Pyrrosia sp.1, Pyrrosia pilloseloides (L) M.G.Price., Pyrrosia sp.2,, Lygodium scandens (L) Sw., Lygodium flexuosum (L) Sw., Drynaria quercifolia (L) J.Sm., Salvinia natans (L) All., Azolla pinnata, Ceratopteris thalictroides (L) Brongn., Lycopodium cernuum, Selaginella ornata (Hook & Grev.) Spring., Vittaria elongata Sw., dan Microsorum punctatum (L) Copel.
