Abstract There were 3,624.5 hectares of the brackish water pond in Aceh Tamiang, which can support the national shrimp export program. The problems arise due to the pond ownership matter, the source of financing, the technology used, and the institutionalization action to improve productivity. The purpose of this research is to improve brackish water pond productivity based on socio-economic aspects in the location. The survey to achieve these aims conducted from April - May 2021, in eight villages in Aceh Tamiang. Data and information were interviewed from 160 pond farmers. Simple statistics and descriptive techniques were used to analyse the data. The main findings are: 91.1 % of the traditional brackish water farmers depend on commercial seed and feed; the productivity of the brackish water pond is between 1.2 tonnes/hectares/year - 2.4 tonnes/hectares/year; the average pond ownership is between 1.1 and 3.4 hectares/farmer; 60% - 94,1% of financial funding to run business depends on their source and the rest from investor or trader. This research recommends: the brackish water farmers in all villages should be organized in one “corporate business” to improve productivity. This institution is owned by farmers based on money stock and managed by professionals.

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).

ABSTRACTIn applying traditional brackish water pond aquaculture of tiger shrimp (Penaeus monodon), plankton is one of water micro organisms that plays an important role as natural food and stability indicator of water or aquatic environment in which life and growth of aquatic organisms depend on water quality variables, both physical and chemical properties. This research objective was to find out the effects of dominant water variables on plankton abundance in brackish-water pond. The research was conducted in traditional brackish water ponds of tiger shrimp in Pasuruan Regency, East Java Province. The research was conducted through direct measurements in the field and also collection of plankton and water samples. Those were then analyzed in the laboratory. Better change to analysis used in this study was regression model analysis was based on the smallest square method. Dependent variables was plankton abundance and independent variables were the water quality variables such as temperature, dissolved oxygen, salinity, pH, total suspended solid (TSS), nitrite, nitrate, ammonia, phosphate, iron (Fe), and total organic matter (TOM). The result showed that range of plankton abundance was 20.0-6,360 individuals/L with average 401.3 individuals/L. There was a significant relationship between plankton abundance and TSS which negatively affected plankton abundance as much as 0.52 or 52%. Based on index values of average dominance, variety, and uniformity, the brackish water pond water or aquatic area in this study was categorized as moderately stable, where plankton genera were well distributed and there was no genus dominating other genus.
