STUDI BESARNYA EROSI PADA AREAL REKLAMASI TAMBANG BATUBARA DI PT ARUTMIN INDONESIA KABUPATEN KOTABARU
Abstract: PT Arutmin Indonesia
as a major coal company, has been trying to implement the principles of
environmentally sound mining, ie, by carrying out reclamation after coal
mining. Erosion that on the area already
reclaimed, is the major problems encountered.The purpose of this study was to
determine the magnitude of erosion and the magnitude of the danger of erosion
(TBE) in various types of land units reclaimed in the PT.Arutmin Senakin. The
results of this study is expected to provide useful information to relevant
parties for consideration in land reclamation and soil conservation efforts and
water, especially in the area of former coal mines. The method used to
predict the magnitude of erosion is the Universal Soil Loss Equation method
(USLE) is raised by Wischmeier and Smith.The results showed that the amount of
erosion occurred in Land Unit I 39.11 tonnes / ha / yr is higher than other
land units, but the total hazard ereosi (TBE) at the very extreme of Land Unit
V 34.41 tonnes / ha / yr , because it
has a value of erosion hazard index (IBE) is more than the Other Land Unit.
