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.

Keberhasilan budi daya tambak udang windu pada awal tahun 1990-an menyebabkan terjadinya pertambahan luas tambak yang cukup besar di Sulawesi Selatan termasuk di Kabupaten Pinrang. Untuk mendapatkan data perubahan luas dan luas tambak terkini di kabupaten tersebut maka dilakukan validasi luas tambak melalui pemanfaatan citra satelit. Citra satelit yang digunakan adalah Landsat-7 ETM+ akuisisi 2002 dan 2005 yang selanjutnya dilakukan klasifikasi. Sedangkan untuk data sebelumnya yaitu tahun 1991 digunakan peta rupabumi Indonesia yang didigitasi dan dilakukan analisis spasial dengan menggunakan SIG. Hasil analisis menunjukkan bahwa luas tambak di Kabupaten Pinrang pada tahun 1991 adalah 7.490,805 ha dan meningkat pada tahun 2002 dan 2005 menjadi berturut-turut 13.366,086 ha dan 14.569,180 ha. Penambahan luas tambak di Kabupaten Pinrang sebagian besar berasal dari konversi sawah dan sebagian lagi berasal dari konversi penggunaan lahan lainnya yang ada di kawasan pesisir.The successful of tiger prawn culture in the brackish water pond in the early of 1990s to cause expansion of brackish water pond area in fairly large in South Sulawesi including Pinrang Regency. To find data of area changing and updating data of brackish water pond area in this regency, was conducted the validation brackish water pond area with satellite image. Satellite image which used was Landsat-7 ETM+ acquisition 2002 and 2005. Satellite image was classified, while the early data, in 1991, was used maps of rupabumi Indonesia that was digitized and conducted spatial analysis with GIS. The results of analysis show that brackish water pond area in Pinrang regency in 1991 was 7,490.805 ha and increased up to 13,366.086 ha and 14,569.180 ha in 2002—2005, respectively. The addition of brackish water ponds area in Pinrang Regency was mainly came from conversion of paddy field and it remaining was from the other land uses type of coastal zone.

Fishery development in Province of South Sulawesi can be devided into two categories, they are marine culture and fisheries, include wild fishery and aquaculture. One of aquaculture is brackish water pond. There are several kinds of fish that can grow in brackish water pond, such as milkfish. Milkfish is a potential commodity which is not only for consume but also for export to abroad. The aim of this research is to knowing the factors which affects the production of milkfish in fishpond. The basic research which used is Explanatory Research. This research takes place in Ma’rang subdistrict Pangkep District. The population is all fisherman which total there are 804 fishermen. Simple random sampling is used to get 80 fishermen as samples. They are consist 57 fishermen in Talaka Village and 23 fishermen in Pitue Village. Primary data is gathered by doing interview with the fishermen. This research is used Cobb-Douglas function for analysis. The results of this research show variable of area of fish raising place, young milkfish, fertilizer, burden and region dummy are have significant effect toward production of milkfish in brackish water pond, while labour, feed, age and experience have no effect toeard production pf milkfish in brackish water pond.
