Abstract

ABSTRACT Ponds were one of the habitats that were used as a place for brackish water cultivation in coastal areas. The cultivation activities carried out have problems. One of the problems faced by farmers in Bontang Kuala today was a decline in production. The purpose of this study was to identify the conditions of ponds that are related to pond fertility, namely physically, chemically and biologically, and the analysis of soil quality. The research method was by analyzing of water quality in situ and ex situ. The parameters analyzed in situ were: temperature, pH, dissolved oxygen, salinity; while the parameters analyzed in the laboratory are: TDS, NO3, NO2 and NH4, soil pH, organic matter, N, P soil, whereas to see the plankton diversity was to take water samples for identification in the laboratory. The results of the analysis of water quality are compared with the environmental quality standards of East Kalimantan Province No. 339 of 1988 (Sea water quality standards for marine biota, aquaculture). Water quality physically and chemically was still in accordance with the standards for cultivation, whereas the soil organic matter was high and biologically the diversity of plankton was in medium category.
