Habitat Characteristics Modelling Dendrocygna javanica (Horsfield, 1821) in North Sumatera, Indonesia, using GIS (Geographic Information System)

Dendrocygna javanica (Horsfield, 1821) is a member of the family Anatidae, the order of Anseriformes, class of Aves, phylum Chordata, of kingdom Animalia. This species is commonly called the Lesser Whistling-duck because it flies in a noisy sound. In Indonesia, it is known as Belibis Batu. Dendrocygna javanica is spread in the regions of Asia including Indonesia. In Indonesia, D. javanica is spread on the islands of Sumatra, Kalimantan, Java, East Nusa Tenggara and West Nusa Tenggara. This study aims to create a distribution model of Dendrocygna javanica based on habitat characteristics in North Sumatra, Indonesia, using GIS (Geographic Information System). A total of 35 distribution points of D. javanica in 8 districts in North Sumatra were analyzed using ArcGis 10.3 software to analyze habitat characteristics. The results showed that D. javanica spread on habitat characteristics Rainfall ranged from 1500-3500 mm/year, 5 soil types namely ferric acrisols (4 points), humic acrisols (4 points), dystric cambisols (2 points), orthic ferrasols (5 point), and dystric fluvisols (20 points), 7 types of land cover namely dryland forest (2 points), plantation (5 points), dryland agriculture (10 points), rice fields (2 points), swamp (4 points), plus (4 points), and body of water (8 points), and are at an elevation of 3-1072 meters above sea level. Dendrocygna javanica is spread in a limited area. This research is expected to be an important source of information in the conservation of D. javanica in North Sumatra
