The purpose of this study to determine the ability of Chlorella vulgaris in absorbing Pb (lead) and the effect of the variation of Pb metal concentration on the growth of Chlorella vulgaris.This study using an experimental study with complete random design with 4 treatments, namely control (without the addition of metal), Pb1 (addition of metal 1 mg / l), Pb3 (3 mg / l) and Pb5 (5 mg / l), respectively 3 replications. Exposure Pb ion in Chlorella vulgaris for 7 days. Analysis of the metal content of Pb concentration performed on culture media after exposure it at 3 hours after dispersion Chlorella vulgaris and on day 7 of culture using the AAS method. Do also counting the growth of cells each day. The results of the analysis of the average metal content of Pb in the culture medium at the end of the study was the control (0.1980), Pb1 (0.1453), Pb3 (0.4144) and Pb5 (0.5305). While the average growth of Chlorella vulgaris at the end of the study were control (630.1116 x 104), Pb1 (829.0012 x 104), Pb3 (1069.9446 x 104) and Pb 5 (808.94450 x 104). The results of the analysis of the content of Pb in the F test shown that the difference in concentration of water Pb given real influence on the ability of Chlorella vulgaris in absorbing Pb and growth. The conclusion of this study was Chlorella vulgaris has the ability to absorb metals in the waters, and the provision of various concentrations of Pb can affect the growth of Chlorella vulgaris.
