Abstract

Abstract: Ferns are a type of biodiversity that is spread to live on the forest floor and plays an important role in ecological functions, such as humus formation, protecting soil from erosion, and maintaining soil moisture. This study aims to determine the distribution of fern species at different heights in the Gunung Raya Protection Forest, Temajuk Village and their potential for the community. The method in this study, namely the cruising method to observe ferns on soil contours with an altitude of 25-125 meters above sea level, 125-225 meters above sea level, and 225-325 meters above sea level. Environmental parameters including temperature, humidity, light intensity, soil pH and wind speed were measured at each altitude.  Herbarium was made to identify ferns. Information about the potential of ferns was obtained from the surrounding community. The results showed that there were 14 species of ferns belonging to 7 families. Ferns found were as many as 14 species at an altitude of 25-225 masl decreased to 10 species at the highest contour (325 masl). The four species that were not found were Stenochlaena palustris, Nephrolepis cordifolia, Hypolepis punctata, and Davalia divaricata. Of the 14 species of ferns, 11 of them have potential as vegetables, medicines, ornamental plants, and craft materials.

Abstract

The practicum guide is a guideline for conducting practicum activities. Cincalok was chosen as the practicum guide because of its closeness to the local wisdom of the students, so that the concept of conventional biotechnology can be understood contextually. The use of locally-based fermented products supports relevant learning, and strengthens students' appreciation of local culture and food resources. This study aims to analyze the feasibility of teaching materials for practical guides on conventional biotechnology sub-material regarding the results of physical, chemical, and organoleptic tests of cincalok in West Kalimantan. The research design used was quantitative descriptive. The feasibility test was conducted in three stages, namely instrument validation, media validation, and data analysis. The validators consisted of five people, namely two lecturers from the Biology Education Study Program and three biology teachers from grade X high school. The validation results obtained a CVR value of 0.99 and a CVI value of 0.99, indicating that all aspects of the practical guide assessment were valid. This shows that the practical guide that was created met the criteria in terms of format, language, and content. The practical guide that met the validity criteria could be used in the next stage to evaluate its effectiveness.
