GIS based: Mapping of Multy Purpose Tree Species (Durio zibethinus) in Perkebunan Tambunan Village, Langkat District, North Sumatera Province, Indonesia

Abstract

Durio zibethinus (durian) in Indonesia is known as one of the types of Multy Purpose Tree Species (MPTS). Durian is a Malvaceae family. It grows naturally as well as is planted on community agroforestry land in Langkat Regency, North Sumatra. This study aimed to map the distribution of land suitability of Durio zibethinus using Geographic Information System (GIS) in Perkebunan Tambuan Village, Salapian Sub district, Langkat District. This study was conducted from February 2019 to July 2019 at the USU Experimental plantation, Perkebunan Tambunan Village, Salapian Sub district, Soil physical and chemical properties analysis were conducted in Central Laboratory and Soil Biology Laboratory, Faculty of Agriculture, Universitas Sumatera Utara (USU). The evaluation of land suitability distribution using GIS was conducted in Laboratory of Forest Inventory, Faculty of Forestry, USU. The land suitability of Durio zibethinus in Perkebunan Tambunan Village was marginally suitable for all land units (Land Unit 1, 2 and 3).
