The development of agroforestry based of Sengon Laut with Porang crop area has successfully to increase people economic level. This research aimed to analyze and compare diversity, composition, structure community of canopy Arthropod at Sengon Laut of Porang crop area and non porang crop area, vertical variation diversity, abundance and to recommend good cultivating management. Samples was taken at two different location by blue and yellow colored water pan trap, which was bottom layer (1-1,5 m) and upper layer (8-10 m). Data of structure community comparison each location was analyzed by important value and diversity (Index Shannon-Whienner, Index Bray-Curtis, variation vertical by anova and Non crop vegetation was analyzed by line intercept method. The result of this research yellow water pan trap had better efficiency on upper layer at non Porang crop. Recommendation to the farmers in order to make good cultivation management non crop vegetation is not cleaned and not used pesticide utilization Keywords: agroforestry, Arthtropod, composition, ecosystem stability
