Abstract :
The waters of Tanjung Mas Semarang are multifunctional areas, tourism,
settlements, industrial activities, households, trade, ports, sea transportation, that
dispose of waste into those waters. The presence of pollutants will affect the
quality of water and aquatic organisms living in these waters. Marine biota that
live in these waters include dogol shrimp (Metapenaeus monoceros) is a mainstay
commodity of the fishery sector that is generally exported in the form of frozen,
has a high nutritional value. The existence of many human activities in Tanjung
Mas Waters that potentially produce waste containing heavy metals including
copper metal that can contaminate water.
This study aims to determine the metal content of copper that accumulates
in dogol shrimp from fish auction at Tanjung Mas Semarang. This research uses
UV-VIS spectrophotometry method. The data obtained were analyzed
descriptively by comparing the food standard based on Decree of Director General
of Food and Drug Control No. 03725 / B / SK / VII / 89, that the permitted level
of copper in food was 20.0 mg / kg. The results showed that the highest metal
content of copper in dogol prawn was in TPI II of 5.3660 mg / kg, the second
highest was in TPI I of 5.3586 mg / kg, while the lowest was in TPI III of 5.3251
mg / kg, still below the specified threshold (20 mg / kg).
