Abstract

Abstract: Pulasan ( Nephelium ramboutan-ake Bill. Liinh.) is one of the genetic sources of the Sapindaceae family which has many benefits, including fresh fruit, processed food industry as well as traditional and modern medicines. Currently, the existence of outward appearance has experienced scarcity, even threatened with extinction. This study aims to determine the distribution and create a map of the outward distribution in the Riau Ecosystem Area. This study uses a survey method, namely the technique of getting outward distribution points by tracking using the Garmin 76csx Global Positioning System (GPS). The data obtained were processed using the Map Source program and ArcGIS 10. The basic map used was a map of the administrative boundaries of Kampar, Kuantan Singingi, Siak and Bengkalis districts as well as a map of soil types. The outward distribution of each sub-district is presented descriptively and in the form of a map. Overlays of germplasm have been explored in as many as 495 trees spread over four districts in Riau. The population of the outward distribution in the mineral soil ecosystem zone is more than the population in the peat soil ecosystem zone. Distributed in groups with unequal populations.
