The location was set as a research location was the location 1, as the areas of a body of a river, Location 2 as the river estuaries, and Location of 3 as ocean waters. Sampling was performed every 2 weeks for 5 times the sampling making use planktonnet with mesh size 45 μm. Sampling was carried out vertically at high tide and low tide began from May to July 2012. The results obtained 49 genera at high tide, while at low tide obtained 44 genera. Abundance obtained when the observation was an average of 17.90 specs/L at high tide, and at low tide the average gained 20.49 specs/L. Diversity of zooplankton an average of 2.20 obtained at high tide, and an average of 2.13 obtained at low tide. Homogeneity obtained average for sampling at the time of high tide and low tide with the same value at 0.56. The index domination at high tide and low tide also have the same value, the average 0.44.
