Analisa NDVI Citra Satelit Landsat Multi Temporal Untuk Pemantauan Deforestasi Hutan Kabupaten Aceh Utara

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 showed that the NDVI value for forest distribution based on vegetation density in 2000 was -0,620438 � 0,628743, in 2003 between -0,364238 � 0,530055 and in 2015 between -0,274592 � 0,642049. The rate of deforestation in the district of North Aceh based on the value of the vegetation index (NDVI) yields 3 classes of deforestation are severe deforestation, light deforestation and not deforested, in 2000 there was deforestation of 25,62%, in 2003 it was 99,91% and in 2015 amounted to 15,89%, most deforestation occurs in production forests.

Literature Review United Nations and Indonesian Government for Management Deforestation Cases in Kalimantan Island

“…war, nulear weapon, have caused the current forest to be damaged or deforested within + 300 years (Keenan et al, 2015;Ramadhini & Sukojo, 2017). Deforestation is the destruction of forests or the reduction of areas that have forests with a variety of factors both by human factors, namely the expansion of agriculture and plantations, mining coal, iron ore, gold, nickel, and etc, the conversion of land into housing and degradation which can later lead to disruption of biodiversity, global climate change, and deprivation of the rights of the livelihoods of local communities around forest areas (McNicol, Ryan, & Mitchard, 2018;Seymour & Harris, 2019).…”

Customary Law of the Forest in North Aceh Regency

“…13 North Aceh Regency is one of the regencies that still have 27 sub-districts and 19 subdistricts which might be regions that have widespread forests as a source of network lifestyles. Now, deforestation and forest degradation are getting better 14 and raise public anxiety about natural disasters. This article analyzes the concept of customary law-based forest management as local wisdom in North Aceh Regency.…”
