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 mm.day-1)
and the highest growth of rhizome Thalassia hemprichii at 4th station (1.3
mm.day-1). 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.
