Analysis of aspects of abundance and diversity of plankton in the waters around the Lantebung mangrove ecotourism area of Makassar City, Indonesia

This study aims to determine the aspects of abundance, diversity, uniformity and dominance of plankton in the waters around the Lantebung mangrove ecotourism area, Makassar City. The study used a survey method. Plankton sampling was carried out using a 25-micron plankton net. Each sample bottle was labeled based on the sampling location and analyzed in the laboratory. Plankton sample testing consists of the number, abundance, diversity, uniformity, and dominance of plankton. The plankton data obtained are then processed and analyzed with descriptive analysis. The results of the study showed that the number, abundance, diversity and dominance of plankton at all observation stations were classified as low or small and the highest was in the plankton type Rhizosolenia sp. Meanwhile, the highest uniformity of plankton species was at station 1 (ST 1), namely 0.078453, and the lowest was at station 2 (ST 2), namely 0.052748.
