ABSTRAK Lahan tambak garam yang sesuai dengan kriteria kesesuaian lahan tambak garam dapat meningkatkan kualitas maupun kuantitas yang dihasilkan. Hal tersebut adanya evaluasi kesesuaian dan keberlanjutan lahan tambak garam. Tujuan dari penelitian ini yaitu mengetahui luasan lahan tambak garam di Pulau Gili Raja serta luasan tingkat kesesuaian dalam aspek teknis, aspek sosial ekonomi, aspek teknis sosial ekonomi dan tingkat keberlanjutan pada dimensi lingkungan, dimensi ekonomi, dimensi sosial, dimensi kelembagaan. Faktor yang mempengaruhi pengelolaan lahan tambak garam yaitu cuaca dan iklim. Metode yang digunakan untuk kesesuaian yaitu pemodelan indeks atau skoring dengan analisis data spasial menggunakan Sistem Informasi Geografis dengan cara query. Metode untuk analisis keberlanjutan yaitu Rapfish (Rapid Appraisal of Fisheries) dengan MDS (Multi Dimensional Scalling). Software yang digunakan adalah ArcGis 10.4 dan Program Rapfish (Rapid Appraisal of Fisheries). Hasil didapatkan luasan tingkat kesesuaian aspke teknis, aspek sosial ekonomi, dan aspek teknis sosial ekonomi sebagai berikut : aspek teknis kelas sesuai (S1) seluas 16,24 Ha (80,11%) dan kelas kurang sesuai (S2) seluas 4,03 Ha (19,88%), aspek sosial ekonomi kelas kesesuaian (S1) seluas 16,16 Ha (79,71%) dan kelas kurang sesuai (S2) seluas 4,11 Ha ( 20,28%), aspek teknis sosial ekonomi kelas sesuai (S1) seluas 17,76 Ha (87,58%) dan kelas kurang sesuai (S2) seluas 2,51 Ha (12,41%), dari hasil skoring ke-tiga aspek tidak dipatkan kelas kesesuaian tidak sesuai (N). Hasil analisis keberlanjutan didapatkan nilai indeks dan status tingkat keberlanjutan dimensi lingkungan senilai 59,50 (Cukup Berkelanjutan), dimensi ekonomi senilai 32,54 (Kurang Berkelanjutan), dimensi sosial senilai 73,43 (Cukup Berkelanjutan), dimensi kelembagaan senilai 73,71 (Cukup Berkelanjutan).

ABSTRACT Salt ponds in accordance with the criteria of suitability of salt ponds can increase the quality and quantity produced. This is an evaluation of the suitability and sustainability of salt ponds. The purpose of this study is to determine the extent of salt pond land on Gili Raja Island and the extent of suitability in technical aspects, socio-economic aspects, socio-economic technical aspects and the level of sustainability in environmental dimensions, economic dimensions, social dimensions, institutional dimensions. Factors influencing the management of salt ponds are weather and climate. The method used for conformity is indexing or scoring modeling with spatial data analysis using Geographic Information Systems by means of a query. The method for sustainability analysis is Rapfish (Rapid Appraisal of Fisheries) with MDS (Multi Dimensional Scaling). The software used is ArcGis 10.4 and the Rapfish (Rapid Appraisal of Fisheries) Program. The results obtained are the extent of suitability of technical aspects, socio-economic aspects, and socio-economic technical aspects as follows: technical aspects of appropriate classes (S1) covering 16.24 Ha (80.11%) and less suitable classes (S2) covering 4.03 Ha (19.88%), socioeconomic aspects of conformity class (S1) covering 16.16 Ha (79.71%) and less suitable classes (S2) covering 4.11 Ha (20.28%), technical aspects of social economy class in accordance (S1) in the area of 17.76 Ha (87.58%) and inadequate class (S2) in the area of 2.51 Ha (12.41%), from the results of the scoring of the three aspects not compressed the suitability class is not appropriate (N) . The results of the sustainability analysis found the index value and the status of the sustainability level of the environmental dimension valued at 59.50 (Moderately Sustainable), economic dimension valued at 32.54 (Less Sustainable), social dimension valued at 73.43 (Simply Sustainable), institutional dimension worth 73.71 ( Self-sustained).
