Abstract
Mangrove have an ecological function which are the ability to absorb, transport, and accumulate toxic materials that come from around the environment where they grow, one of which is lead (Pb) heavy metal. This study aims to determine the ability of water bodies, sediment and response of mangrove root Avicenia marina in accumulating heavy metal lead (Pb) in the waters of Mangrove Tourism of Muara Angke, Jakarta, Indonesia. Samples taken in the form of mangrove root Avicenia marina, water, and sediment. Then the samples were analyzed in the Laboratory using the Atomic Absorption Spectroscopy (AAS) method. The results showed accumulation of lead in mangrove root is 1.45  1.00 mg/L. Lead accumulation in the sediment have a mighty relationship with lead accumulation in the root of Avicenia marina with r=0.87, F= 31.76 and p<0.001, and the response of mangrove root of Avicenia marina to the lead contaminant determined by concentration amount of lead, time interaction, sediment type, and water flow. Muddy sediment type is a special sediment lead traps in the coastal.
