Isolation and identification of decomposer fungi from Macaranga indica and Hibiscus macrophyllus leaf litter from restoration area of Gunung Leuser National Park

Abstract

Leaves mostly litter on the forest floor. The process of leaf litter decomposition involves the role of microorganisms such as fungi. The study aimed to isolating and identifying the fungi of Macaranga indica and Hibiscus macrophyllus leaf litter. The leaf litter was taken under the stand of Macaranga indica and Hibiscus macrophyllus in the restoration area of Gunung Leuser National Park Sei Betung Resort North Sumatra. Fungi were isolated using the direct plating methods with Potato Dextrose Agar medium. The purified fungi were then identified morphologically to the genus level. Morphological identification carried out by looking at the macroscopic and microscopic features of fungi. There were six isolates from Macaranga indica leaf litter and eight isolates from Hibiscus macrophyllus leaf litter. The result shows that there are five genera of fungi consisting of Aspergillus, Penicillium, Mucor, Trichoderma, and Cladosporium.
