Isolation and Identification of Endophyte Fungi in Fers in Coban Curah Watu as Potential Teaching Materials For Grade X SMA Fungi Isolasi dan Identifikasi Fungi Endofit pada Tumbuhan Paku di Coban Curah Watu sebagai Potensi Bahan Ajar Materi Fungi Kelas X SMA

Abstract

This study aims to isolate and identify endophytic fungi found in fern leaves (Pteridophyta) in the Coban Curah Watu area, and to examine their potential as a source of teaching materials for grade X high school fungi in accordance with the independent curriculum. The background of this study is the importance of utilizing local potential as a contextual learning resource that can improve student understanding. The study uses a mixed method approach with an embedded design model, combining qualitative and quantitative methods. Fern samples were taken by purposive sampling, then isolated using PDA media and identified the morphology of fungi macroscopically and microscopically. The results of the study showed the diversity of endophytic fungi, including the genera Aspergillus, Penicillium, and Fusarium, which have unique characteristics and biological potential, especially in producing secondary metabolite compounds. These findings were developed into learning media in the form of posters that were tested on high school students. Student responses showed high enthusiasm, interest in the material, and an increased understanding of the concept of fungi through a contextual approach. Thus, the results of this study not only enrich information about the diversity of endophytic fungi in ferns, but also have the potential to be meaningful, innovative, and environmentally-based biology teaching materials for students.
