## Abstract
Abstract Increased human activity in all sectors due to rapid development, often resulting in pollutants such as heavy metals that have an impact on the environment and one alternative is phytotechnology. This study aims to (1) Determine the seagrass’s capacity to absorb lead (Pb) and copper (Cu), (2) Determine the optimization of seagrass, sediment, and seawater in absorbing Pb and Cu. This study was an experimental study carried out at the Hasanuddin University hatchery unit, Barrang Lompo Island, then analysis of Pb and Cu metal content in the Analytical Chemistry Laboratory of the Department of Chemistry, Faculty of Mathematics and Natural Sciences, Hasanuddin University using the Atomic Absorption Spectrophotometer (AAS). The results showed that Enhalus acoroides seagrass had capacity dal am absorbed Pb of 0.08 mg/kg at a concentration of 120 ppm, while dal am absorbed Cu of 0.65 mg/kg at a concentration of 2 ppm, so that this seagrass is more effective at absorbing Cu than Pb, the Pb optimum results in seawater at a concentration of 120 ppm at 3.04 mg / L and sediment at an concentration of 80 ppm at 29.30 mg/kg, while the optimum yield of Cu content in seawater and sediments, obtained at concentrations of 1 ppm and 2 ppm, namely 0.56 mg/L in seawater and at a concentration of 4 ppm is 29, 67 mg / kg in sediment. While the optimal absorption of Pb by seagrass occurs at low concentrations of 40 ppm and 80 ppm of 0.07 mg/kg. The same result was obtained in sediments, 29.22 mg/kg at a concentration of 40 ppm. While the optimum Pb content in seawater is at a concentration of 40 ppm of 1.26 mg / L.
