Ecological and Anthropological Impact on Diversity Echinodermata in the South Beach Area, Indonesia

Abstract

The Sancang Beach is overgrown by various types of seagrass, algae, coral reefs, and mangroves so it has the potential for the life of marine biota, including the Echinoderms phylum. This research aims to describe the diversity of the Echinoderms phylum in Sancang Beach, Garut District. This research was conducted from November 2019 to December 2020. The type of research conducted is descriptive research using the purposive sampling method located in Ciporeang to Cibako. Echinoderm data was collected using the Belt Transect technique along 100 m which was drawn perpendicularly from the coast to the sea with a plot measuring 1x1 m. Data analysis used the Shannon-Wiener diversity index formula. Identification is done by comparing the morphological species obtained with the morphological characteristics in the Identification book. Overall observation results obtained Echinoderms as many as 12 species consisting of 5 classes, 7 orders, and 7 families with an average diversity index value on the beach of Sancang Garut District, namely H '= 1.07. The conclusion is that the level of diversity in Sancang Beach, Garut District is moderate.
