KELAYAKAN LAHAN PERTAMBAKAN DI TANAH SULFAT MASAM, KABUPATEN LUWU TIMUR, SULAWESI SELATAN
Abstract
Salah satu lahan yang bisa dikembangkan untuk budi daya tambak adalah tanah sulfat masam. Di Indonesia potensinya cukup luas dan umumnya lahan semacam ini berada di kawasan pesisir. Penelitian ini bertujuan untuk mengetahui potensi kelayakan lahan tanah sulfat masam untuk pertambakan dan optimalisasi pemanfaatannya berdasarkan tingkat kesesuaian lahan dan daya dukung lingkungan. Penelitian dilakukan di Kabupaten Luwu Timur, Sulawesi Selatan. Metode penelitian dengan melakukan survai untuk mendapatkan data primer. Sedangkan data sekunder diperoleh dari instansi terkait dan peta yang diperlukan untuk proses analisis dengan Sistem Informasi Geografis (SIG). Analisis data melalui tumpang susun dari beberapa peta dan data primer pada setiap pengamatan dengan mempertimbangkan pembobotan dan skala penilaian untuk mendapatkan nilai skoring dalam menentukan kesesuaian lahan budi daya tambak. Hasil analisis kelayakan lahan untuk tambak didapatkan nilai potensi dan kelayakan seluas 5.617,9 ha yang terdiri atas 709,4 ha kelayakan tinggi; 3.947,7 ha kelayakan sedang; dan 960,7 ha kelayakan rendah.
One of land that can be developed for brackish water aquaculture is acid sulfate soil. The potency of acid sulfate soil in Indonesia is relatively large and generally found in coastal area. The objectives of this research to know the potency and land suitability of acid sulfate soil for brackish water aquaculture and optimal utilization based on land suitability level and its carrying capacity. This research was conducted at Malili Sub District; East Luwu Regency, South Sulawesi. Surveys have been done collected primary data. while secondary data was obtained from related Institution and needed maps for Geographic Information System (GIS) analysis, with overlying maps and primary data in each station observation with considering and assessment scale value of determining land suitability for brackish water pond. The result of maps analysis had been obtained the potency and land suitability at Malili Sub district were 5,617.9 ha consisted of 709.4 ha (high suitability); 3,947.7 ha (moderate suitability); and 960.7 ha (low suitability).
