Abstract

One of the functions of the forest is natural disaster such as flood control and the landslide that is how these forests absorb water into the root of the tree. Most forests in North Aceh Regency is protected forest which has undergone deforestation due to the presence of illegal logging and opening of new land like planting oil palm that impact against water infiltration. This research was conducted to identify deforestation forests in 2000, 2003 and 2015 using the techniques of remote sensing by satellite images landsat landsat 7 and 8. The method used was algorithm NDVI to get the classification of forest distribution and the level of deforestation forests based on the density of the vegetation from the Forestry Department 2003. Analysis of the rate of deforestation and loss of vast forests is done by leveraging the value of NDVI and other supporting data. The results of this research show that the increasingly low NDVI values can occur due to the interference of clouds, fog and smoke at the time of recording, so that the satellite image area non vegetation is larger than the area of vegetation, vegetation index value based on deforestation largely occurs on forest production which are more easily accessible due to the many possible means of road, while the protected forest have the means of access are more difficult to reach. The broad decline in forests that are experiencing deforestation, namely in the amount of 84.06% by 2015.
