ABSTRACT: The research about
analysis of heavy metal lead (Pb), cadmium (Cd) and mercury (Hg) in Octopuses
(Loligo sp.) obtained from TPI Tambak Lorok Semarang has been carried out. This
research was intended to identify heavy metals accumulating in octopuses
(Loligo sp). The objects studied in this research were octopuses obtained from
Tambak Lorok marketplace in Semarang. The sample for this research was taken by
simple random sampling at three different points of locations. The locations 1,
2 and 3 were located each from the west, the north and the east, respectively,
from the port. The contents of lead, cadmium and mercury in the octopuses’
bodies were measured using SSA (Atom-Absorption Spectrophotometer). The
obtained data were then tested using One-way anava. The differences in metal
contents were analyzed using Scheffe’s tests and then compared with the basic
quality standard stipulated in the Decision Number 03725/B/SK/VII/1989 by the
POM Directorate General The study based on the three different points of
locations showed the following results. The average lead contents in the
octopuses obtained from the points of locations 1, 2 and 3 were 0.29 mg/kg,
0.24 mg/kg and 0.25 mg/kg respectively. The average cadmium contents in the
octopuses obtained from the points of locations 1, 2 and 3 were 0.04 mg/kg,
0.05 mg/kg and 0.06 mg/kg respectively. The average mercury contents in the
octopuses obtained from the points of locations 1, 2 and 3 were 0.06 mg/kg,
0.07 mg/kg and 0.07 mg/kg respectively The lead, cadmium and mercury contents
in the octopuses obtained from the three locations had not exceeded upper limit
stipulated in the Decision Number 03725/B/SK/VII/1989 by the POM Directorate
General. Based on the One-way ANOVA statistical tests on the lead contents,
there was no significant difference among the three samples, but the
statistical tests on the cadmium and mercury contents showed a significant
difference among the three different points of locations relating to these
heavy metal contents in the octopuses.
