INVENTARISASI KEANEKARAGAMAN LUMUT KERAK (LICHENES) DI TELAGA SARANGAN SEBAGAI SUMBER BELAJAR BIOLOGI

Telaga Sarangan is one of the tourist areas located in Magetan Regency, East Java, that holds significant potential in terms of biodiversity, including its relevance to Lichenes-based biology learning. Lichens are symbiotic organisms known for their sensitivity to environmental changes, making them useful as natural bioindicators. Moreover, Lichens can serve as meaningful contextual learning materials in biology education.
This study aims to identify the species of Lichenes found in two locations (stations) and analyze their diversity level as a basis for developing a biology learning resource. Data collection employed a quantitative approach using a descriptive method through belt transect techniques measuring 10×20 meters per plot, consisting of 10 plots in Station 1 (2,000 m²) and 15 plots in Station 2 (3,000 m²). The observed data included colony counts, thallus types, and environmental parameters such as temperature, air humidity, and light intensity. The results revealed seven identified Lichen species: Flavoparmalia ceperata, Cryptothecia striata, Parmeliopsis hyperopta, Pertusaria paratuberculifera, Parmotrema perlatum, Lepraria lobificans, and Parmelia saxatilis. The diversity index (H') at Station I was 1.2653 (E = 0.7862; C = 0.3554) and at Station II was 1.2642 (E = 0.7855; C = 0.3622), both categorized as moderate diversity levels.
The findings were further developed into a biology learning media in the form of an draft e-booklet designed to align with Phase E learning outcomes in the Kurikulum Merdeka. It is expected that students will enhance the contextual relevance of learning materials and raise their awareness of the importance of conserving the surrounding environment. Additionally, this research may serve as a reference for future studies
