Physiological Response of Thallasia hemprichii on Antrophogenic Pressure In Pari Island, Seribu Islands, DKI Jakarta

Abstract: Seagrass ecosystem is one of tropical marine ecosystem and have important function. The function of ecosystem like a feeding and nursery ground for marine biota. Antrophogenic pressure is one of threat for seagrass ecosystem sustainability. This research study about effect antropogenic pressure for seagrass Thallasia hemprichii physiology response in some different location at Great Barrier Pari Island. The physiology response study cover growth, heavy metal bioaccumulation and histology analysis. The result shows that growth of leaf and rhizome Thalassia hemprichii have positif correlation with nutrient consentration in environment. The highest growth of leaf Thalassia hemprichii at 2nd station (4.16 and the highest growth of rhizome Thalassia hemprichii at 4th station (1.3 Seagrass can accumulation heavy metal from environment. The highest heavy metal accumulation is Pb. Not correlation between heavy metal consentration in seagrass with heavy metal concentration from environment. Analysis histology result that not damage seagrass tissue in all research station.
