| dc.description.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. | en_US |
