Analysis of Plankton Abundance, Diversity and Dominance along the Siddo Coast in Barru Regency, Indonesia

Abstract

This research aims to determine the level of abundance, diversity, uniformity, and dominance of plankton in the waters of Siddo Beach, Barru Regency. The research was carried out at three research locations, namely location 1, namely the hatchery location and Siddo Beach Bay; location 2, namely the location around the pier and mangroves; and location 3, namely the location around the community settlement in Toe hamlet, Barru Regency. Plankton in this location needs to be researched because there are many environmental forces that can disrupt the existence of plankton. Analisis plankton dilaksanakan di Laboratorium Kimia dan Air Politeknik Pertanian Negeri Pangkep. Data selanjutnya dianalisis dengan analisis deskriptif. The results showed that the abundance of plankton at location 1 was highest for plankton of the Navicula sp type; at location 2, the highest was for plankton of the Oscilatoria sp type; and the abundance of plankton at location 3 was highest for plankton of the type Acartia sp. The average diversity of plankton at the research location is in the range of 0.1526795-0.20716, the uniformity of plankton at the research location is in the range 0.06144279-0.10646145, and the dominance of plankton at location 1 is highest in Cosconidiscus sp type plankton, location 2 is dominated by Oscilatoria sp type plankton, and location 3 is dominated by plankton of the Acartis sp type. Thus, there is no type of plankton that has the highest abundance and dominance for all research locations.
