Cu (Cuprum) Pollution Effect from Shrimp Processing

Abstract

Abstract Litopenaeus vannamei shrimp is a type of aquaculture shrimp, easily maintained in fresh water, short-lived, at a lower cost compared to other types of shrimp cultivation. So vannamei shrimp is more available in traditional markets. The cultivation of vannamei shrimp uses fisheries technology in its feed, which is a cuprum (Cu) mixture. The study was conducted by taking samples of Litopenaeus vannanmei species purchased in 8 traditional markets spread throughout the city of Surabaya. Each market is taken 5 random samples of shrimp with relatively the same size and condition. Then it is processed by steaming, boiling, frying and burning. Determination of Cu heavy metal content in shrimp is carried out using atomic absorption type AA 3e00 Variant Tech tron (AAS), with a few additional 50 ml glass cups, 10 ml volumetric flask, 5 ml polyethylene vial, 10-100 effendorf micropipette μl and analytical balance. There was a significant difference between boiling (p = 0,000) and steamed (p = 0,001) with shrimp in raw conditions. Whereas for processing by grilling (p = 0.989), and by frying (p = 0.078) showed insignificant results. This means that there is no significant difference in Cu content in shrimp, between raw conditions and processing by being grilled and fried.
