Abstract

Heavy metals copper (Cu) was microelements needed by organisms in small quantities. The type of plankton that could be used as a bioremediation agent because of its abundance and resistance in nature was Skeletonema costatum. This study aims to determine the effect of different density of Skeletonema costatum exposure Cu and Determine the effect of exposure to the growth of Skeletonema costatum. The design used in this research was an experimental method. This research using Completely Randomized Design (CRD) with three treatments and six replications. Treatment used was 5,000 cells/ml (A), 10,000 cells/ml (B), and 15,000 cells/ml (C) of cells density at 1 ppm Cu concentration. The results of this study prove that the density of Skeletonema costatum could affect Cu uptake levels with the absorption percentage of treatment A was78,62b ± 10.40; the absorption percentage of treatment B was 88,13ab ± 7.49; the absorption percentage of treatment C was 91,96b ± 4.87. Culture media that contained 1 ppm Cu concentration could affect the growth and growth phase of Skeletonema costatum. Skeletonema costatum that exposed cells with Cu has higher growth than with Cu reviews those not exposed.
