Abstract

Mangrove ecosystem has  the role of interface ecosystem between land and sea. It has social, economic and ecological functions. The decreasing quality and quantity of mangrove mangrove forrest has resulted in environmental damage. Langsa City has mangrove forest in damaged condition because of conversion into fish ponds, illegal logging, pollution and settlements. The purpose of this research was to determine the level of land suitability of rehabilitated mangrove areas. The research was conducted in Langsa City, Aceh. Location and method of this research determined by purposive and descriptive with survey techniques. The Analytical method used is a suitability analysis. According to land suitability matrix and spatial analysis, there were three types of mangroves that can be used for rehabilitation programs in the study area like Rhizophora spp., Avicennia spp., and Sonneratia spp. In land suitability level, Rhizophora spp. had the highest of land suitability around 1.263,92 ha (66,88%).


Ekosistem mangrove merupakan wilayah yang berperan sebagai peralihan antara daratan dan lautan yang mempunyai fungsi ekologi, sosial ekonomi, dan fisik. Menurunnya kualitas dan kuantitas hutan mangrove telah mengakibatkan kerusakan lingkungan. Kondisi hutan mangrove Kota Langsa pada saat ini mengalami kerusakan. Faktor utama penyebab kerusakan, antara lain konversi hutan mangrove menjadi tambak, pembalakan liar, pencemaran, dan permukiman baru. Tujuan penelitian untuk menentukan tingkat kesesuaian lahan pada areal rehabilitasi mangrove. Penelitian ini dilakukan di Kota Langsa, Aceh. Penentuan lokasi penelitian dilakukan secara purposive dan menggunakan metode deskriptif dengan teknik survei. Analisis kesesuaian lahan dan analisis spasial untuk mengetahui tingkat kesesuaian lahan mangrove digunakan dalam penelitian ini. Hasil penelitian menunjukkan, ada tiga jenis mangrove yang dapat digunakan untuk program rehabilitasi, yaitu: Rhizophora spp., Avicennia spp., dan Sonneratia spp. Berdasarkan tingkat kesesuaian lahan, jenis Rhizophora spp. mempunyai tingkat kesesuaian lahan tertinggi. Luasan lahan yang dapat ditanami jenis Rhizophora spp. seluas 1.263,92 ha (66,88%).
