Evaluasi Kesesuaian Jenis Pohon di Hutan Kota Pesanggrahan Sangga Buana, Jakarta Selatan

Abstract

Pembangunan hutan kota memerlukan perencanaan melalui pemilihan jenis pohon yang sesuai berdasarkan tapak agar manfaat dan fungsi hutan kota optimal. Penelitian ini bertujuan menilai tingkat kesesuaian jenis pohon berdasarkan agregat faktor silvikultur, manajemen, estetika, dan kesehatan pohon. Prosedur penelitian meliputi penentuan kriteria faktor evaluasi, pengumpulan data, pembobotan kriteria menggunakan Analytical Hierarchy Process, penyusunan persamaan evaluasi kesesuaian jenis pohon, penentuan tingkat kesesuaian jenis pohon di masing-masing area. Penelitian menghasilkan persamaan evaluasi kesesuaian jenis pohon pada: a) area jogging track= 0,16.S + 0,48.M+ 0,07.E + 0,29.K, b) sempadan sungai= 0,20.S + 0,24.M + 0,05.E + 0,50.K, c) playground= 0,11.S + 0,28.M + 0,14.E + 0,46.K; dimana: S= skor faktor silvikultur, M= skor faktor manajemen, E= skor faktor estetika, dan K= skor faktor kesehatan. Jenis pohon dengan kesesuaian sangat tinggi pada area jogging track yaitu sukun dan kecapi. Pohon petai cina, kedondong, dan nangka memiliki kesesuaian yang tinggi di sempadan sungai. Pada area playground pohon trembesi, bunga kupu-kupu, melinjo, kamboja, dan matoa memiliki kesesuaian yang sangat tinggi.

The development of an urban forest requires planning through 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 trees species based on factor aggregate of silviculture, management, aesthetic, 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, 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.S + 0,48.M + 0,07.E + 0,29.K, b) river border= 0,20.S + 0,24.M + 0,05.E + 0,50.K, c) playground= 0,11.S + 0,28.M + 0,14.E + 0,46.K; where: S= silvicultural factor score, M= management factor score, E= aesthetic factor score, and K= health factor score. The tree species with a high suitability on the jogging track area are breadfruit and cotton fruit. The leucaena, june plum, and jackfruit trees have a high suitability at the river border. In the playground area, rain tree, butterfly tree, gnetum, frangipani, and matoa have very high suitability.
