Kajian Tingkat Bahaya Erosi Dan Indeks Nilai Penting Di Hutan Rakyat Di Desa Candiwulan Kecamatan Kutasari Kabupaten Purbalingga
Abstrak: This study was aimed
at assessing the danger level of erosion, vegetation conditions, and the
relationship between the level of erosion and vegetation in the community
forest in Candiwulan Village, District Kutasari, Purbalingga. The results
showed that the rate of erosion in forest areas studied was at 56.62 or go to
class II or mild (erosion rate between 15-60 tonnes / ha / year), plants that
are found in forest areas quite diverse.
There are12 plant seedling species, 14 species of saplings plants, 11
species of pole plants and 12 species of trees.
While in zone II there were only 9 plant species. The calculation included the relative
density, relative frequency and relative dominance to known important value
index (IVI) to determine the role of each of the plants in both zones. The
dominant role of plants at the seedling stage is coffee with IVI 70.49, coffee
saplings showed INP 51.77, the teak
poles with IVI 76.69 and tree of Albizia with IVI 108.79. The vegetation
diversity in the area of community forest Candiwulan Village has caused mild
erosion at hazard level. The cultivating patterns and the type of crops
cultivated influence the erosion and run off because it affects the land and
the soil cover and the production of organic material that serves as a ground
cover.
