Analisis Kerapatan Vegetasi pada Kelas Tutupan Lahan di Daerah Aliran Sungai Lepan
Analisis Kerapatan Vegetasi pada Kelas Tutupan Lahan di Daerah Aliran Sungai Lepan
Gunung Leuser National Park (TNGL) is upstream of Watershed Lepan which is a conservation area that must be kept existence. Due to population growth the community needs for land increases, so that one of the steps taken to convert forests to meet their needs. Damage to TNGL will affect the balance of watershed ecosystem Lepan. This research was conducted by using Geographic Information System (GIS), Remote Sensing, which is a spatial technology. Analyses were performed with menampalkan (overlay) multiple spatial data to obtain data land cover changes that occur in the watershed Lepan from year 2005 to 2015, and the value range of NDVI (Normalized Difference Vegetation Index) to determine the density of the vegetation in the watershed Lepan. The results showed forest cover in 2015 amounted to 28.1% of the total watershed Lepan means do not meet the minimum standards set by the government in Act 41 of 1999 on Forestry namely forest area must have at least 30% of the total area of a DAS. This research is expected to provide information for consideration in Lepan watershed management efforts. 121201031
