Java Sea, it is heavily impacted by climate changes and human activities. It has become a wastewater disposal site for the three locations sampling Jakarta, Semarang, Surabaya also domestic sewage, and industrial and agricultural waste are deposited in it. Organic waste is delivered directly to the rivers without special treatment and is then transported into the bay. There have been significant land-use changes, with conversion of 80% of vegetative areas into urban use. Organic non-point source pollution has also affected the bay, likely through riverine input. The present research will perform a coupled hydrodynamic-biogeochemical model, developed by Koropitan (2008). Outcome of the research is a synthesis of climate change and anthropogenic impacts to primary productivity of the Java Sea which is important for mapping the vulnerability index in the Java Sea using the dynamic modeling system to management coastal environmental resources.
