Oyster habitat in a body of water often contain excessive metal content. This research aimed to decrease of Cu level concentration and understand the change of granulocyte in oyster body after being treated for sea water for 12 hours. This research used experimental method with Completely Randomized Design consisting 4 treatments and 3 replications. Cu concentration was measured by using AAS method and the amount of hemocyte (granulocyte) was calculated by using haemocytometer. Cu concentration in oyster before treatment was 0.374 ppm. Immersion with the water discharge of 0.05 m/s for 12 hours was able to decrease Cu 46 % (0.158 ppm of Cu residue) with the lowest granulocyte (31.92 %). © Published under licence by IOP Publishing Ltd.
