<![CDATA[South Banawa District is one of the areas in Donggala Regency which has the best prospects in the pond aquaculture sector because this area has the potential to produce milkfish and shrimp. The earthquake and tsunami of 28 September 2018 damaged most of the ponds in South Banawa District. This study aimed to analyze the composition, diversity, and dominance of plankton in fish and shrimp farming ponds in Lalombi and Tolongano Village. The diversity index (H ́) of plankton in the two villages, namely Lalombi, ranges from 0.3040-1.0769 (phytoplankton), 0.4385-0.4610 (zooplankton) and Tolongano, it ranges from 0.2219-1.2318 (phytoplankton), 0-1.3297 (zooplankton). The results of this diversity are included in the low community category, which means that the condition of the plankton community is unstable, so the condition of the community is experiencing environmental disturbances, caused by changes in the structure of the soil texture due to the earthquake and tsunami. The dominance index values ranged from 0.4227-0.9033 for and from 0-0.2778 for Dominance index values close to one mean that under current conditions there is a dominant type of but for the value was close to zero, which means that there was no species dominating the structure of the community. uniformity index values ranged from 0.1562-0.4957 and those for ranged from 0-0.9592.]]>
