Keanekaragaman Jenis Jamur pada KPH Wilayah IX Panyabungan, Kabupaten Mandailing Natal, Sumatera Utara

Abstract

Indonesia is a tropical country that has relatively high humidity so it is very supportive of mushroom growth. Mushrooms have various functions besides being used as medicinal materials, they also play a role in maintaining the balance of the ecosystem. One of the forest areas that is a mushroom habitat is KPH Region IX Panyabungan. Research on mushrooms in KPH Region IX has never been done before. This study aims to determine the types of mushrooms that exist in KPH Region IX Panyabungan, to determine the benefits of mushrooms and the environmental conditions of mushroom habitats in KPH Region IX. The data collection method was carried out with mushroom exploration techniques in the field. The method of processing mushroom habitat data was carried out using Principal Component Analysis (PCA). The results showed that there were 54 species of mushroom consisting of 2 divisions, 4 classes, 11 orders, 26 families, and 43 genus with saprophytic mushroom found as much as 90.91%, ectomycorrhizal fungi as much as 7.27%, and saprophytic and ectomycorrhizal mushroom as much as 1.82%. The correlation between the number of species with light intensity (-0.133), temperature (-0.127) and slope (-0.432) is negative meaning that the higher the light intensity, temperature and slope, the number of fungal species will decrease. While the relationship between pH (0.197), altitude (0.255) and humidity (0.395) is positive, meaning that the higher the pH, altitude and humidity, the number of fungal species found will increase.
