ABSTRACT

Sidoarjo as one potential area of aquaculture ponds very wide. Aquaculture sector can contribute
large revenues for Sidoarjo regency, but with the emergence of mudflow case PT. Lapindo led to a
decline in production in the aquaculture sector. One of the factors that can affect the production
decline is the pollution of mudflow PT. Lapindo, which is heavy metal. The purpose of this study
was to conduct a study of the impact of the mudflow events in the District Sidoarjo for aquaculture
activities. Samples were tested heavy metal content in this study is the gill and shrimp meat and
pond water samples and water reservoir. While heavy metals identified are lead (Pb), Mercury (Hg),
Copper (Cu) and cadmium (Cd). Observations on heavy metal content of pond water samples and
organ gill and shrimp meat showed a relatively high number compared with the water quality standard
for production and consumption. In the area range first (5 km), the highest heavy metal contents
are shown in black tiger shrimp gill samples, the 0255 ± 0029 ppm (Lead), 0142 ± 0041 ppm
(Mercury), 0694 ± 0048 ppm (Copper) and 0035 ± 0007 ppm (Cadmium). While in the area of the
second range (10 km), the metal content highest weight indicated on the shrimp gill samples, namely
0124 ± 0009 ppm (Lead) 0089 ± 0018 ppm (Mercury), 0356 ± 0013 ppm (Copper) and 0023 ±
0004 ppm (Cadmium). In the third range area (15 km), similar results are shown in sample Gill 0049
± 0007 ppm (Lead), 0062 ± 0015 ppm (Mercury), 0091 ± 0018 ppm (Copper) and 0019 ± 0006
ppm (Cadmium). The farther the distance from the center spurt pond, the less content heavy metals
was observed. However, the heavy metal content has been identified the majority of the area was
also the third range has exceeded the water quality standard as well as production for consumption
except Lead (Pb) and Cadmium (Cd) on samples of pond water and mercury (Hg) in the samples
gills and shrimp meat.
