Factor B is indicating to study location with vegetation (Rhizophora sp) and no vegetation. In order to analyze plankton abundance, a quantitative descriptive analysis was applied, in addition of ANOVA test to analyze the growth. The result indicated that between two study ponds is different. The number of plankton per liter water from vegetated pond has more plankton individual than the sample from non-vegetated pond.
