Evaluation of tree species suitability in Pesanggrahan Sangga Buana Urban Forest, South Jakarta

The development of an urban forest requires planning by selecting appropriate tree species based on the site so that the benefits and functions of the urban forest are optimal. This study aimed to assess the level of suitability between the tree species based on factor aggregate of biomorphology-ecology characteristics, management, aesthetic-safety, and tree health. Research procedures include determining evaluation factor criteria, data collection, weighting criteria using the Analytical Hierarchy Process, preparing tree species suitability evaluation equations, and determining the level of suitability of tree species in each area. The research produced equations for evaluating the suitability of tree species in: a) jogging track= 0,16.B + 0,48.M + 0,07.E + 0,29.K, b) river border= 0,20.B + 0,24.M + 0,05.E + 0,50.K, c) playground= 0,11.B + 0,28.M + 0,14.E + 0,46.K; where: B = biomorfology-ecology characteristic factor score, M= management factor score, E= aesthetic factor score, and K= health factor score. The tree species most suitable on the jogging track area are breadfruit and cotton fruit. The leucaena, june plum, and jackfruit trees have high suitability at the river border. Rain, butterfly, gnetum, frangipani, and matoa are very suitable.
