EFEKTIVITAS LARUTAN JERUK NIPIS TERHADAP PENURUNAN KADAR MERKURI (Hg) PADA IKAN TONGKOL (Euthynnus sp)
ABSTRACT: Belawan waters have
been contaminated with heavy metals such as lead (Pb), cadmium (Cd), and
mercury (Hg). Belawan sources of marine pollution caused by industrial waste
results. Mercury (Hg) is the most toxic heavy metals that are harmful to
health. Water biota that live in the waters of Belawan will accumulate the
metal in the body tissue through the food chain. In fact, fish and shellfish is
a popular seafood Indonesian society. This research aims to study if there is
or not the different of the declining of mercury content to the fish in market
of KUD Gabion Belawan and the variation of concentration and submersion on
citric.This research is Quasi Experiment study with complete random sampling
with two factors, i.e. the first factor is variation of concentration and the
second one is variation of duration of submersion. This research was conducted
on March up to May 2015. The population in this research is tuna fish that sold
in KUD Gabion Belawan from the sea of Belawan and the sample in this research
is tuna fish with weight 1,2 kg. The data was analyzed by statistical test
Friedman. The results showed that decreased levels of mercury (Hg) in the of
concentration of 0%, 25%, 50%, and 75% for 5 minutes at 0.875 ppm, 0.0786 ppm,
0.0725 ppm and 0.0584 ppm, while the concentration 0 %, 25%, 50%, and 75% for
10 minutes at 0.0869 ppm, 0.0624 ppm, 0.0587 ppm and 0.0336 ppm. The results of
test Friedman showed that the difference of the four concentration (0%, 25%,
50%, 75%) of citric to the declining of content of mercury (Hg) (p<0.001)
and the duration of submersion (5 minutes and 10 minutes) (p= 0.001) of the
citric to the declining of mercury content (Hg.)
The public are advised to soaked with lime solution concentration 75 %
for 10 minutes before cooking to declining of mercury (Hg) in tuna. Government
should control Belawan waters pollution water biota such as fish for
consumption by the public, by advanced research needs to be done with an acid
solution such as vinegar, tamarind the levels to declining heavy metal o such
as lead (Pb), cadmium (Cd).
