KANDUNGAN TEMBAGA (CU) DAN SENG (ZN) PADA IKAN MAS (Cyprinus commonio L.) DAN NILA (Oreochromis niloticus) YANG DIBUDIDAYAKAN DI KOLAM PASCA TAMBANG BATUBARA
ABSTRACT: The purpose of this
study was to determine the heavy metal content of Copper (Cu) and Zinc (Zn) in
the flesh of carp and tilapia were cultured in post coal mine pond. Fish used
in this study were carp and tilapia with average size of 7.5 cm each and
average weight of 13.5 g each. The preparation of carp and tilapia was used
with dry destruction method then the heavy metal contents of carp and tilapia
detected using of AAS (Atomic Absorption Spectrophotometer). The water quality
was observed as a supporting data. The results showed that the flesh of carp
and tilapia were containing of heavy of Cu and Zn. The highest Cu content in
carp was 0.0008 mg / Kg and some of them were not detected. The highest Zn
content was 0.1577 mg / Kg and lowest was 0.1062 mg / Kg. While on tilapia the
highest Cu content was 3.0732 mg / Kg and lowest was 0.5317 mg / Kg, whereas at
the other weeks were not detected. The highest Zn content was 0.1555 mg / Kg
and lowest was 0.0731 mg / Kg. In the body of carp and tilapia there were the
heavy metal content of Cu and Zn. Profile of highest heavy metal of copper (Cu)
and Zinc (Zn) content in the flesh of carp and tilapia was fluctuated during
the one-month cultivated period.
