Abstract

Echinodermata is one of the main constituents of marine biodiversity
that has an essential role in the marine ecosystem. The purpose of this
study was to look at the composition of Echinodermata by looking at the
diversity index, abundance, dominance, and similarity of the two
Echinodermata locations found, as well as looking at supporting abiotic
factors by correlating abiotic factors with the number of Echinodermata
found at Ngentup Beach and Banyu Meneng Beach. The research was
conducted in July-October 2020 with a purposive sampling method using
line transects then the data was analyzed with the Microsoft Excel
program and PAST v.4.03. This study obtained 9 species at Ngentup
Beach and 11 species at Banyu Meneng Beach. The Echinodermata
diversity index is 1.864 (Ngentup Beach) and 1.117 (Banyu Meneng Beach)
respectively. The Echinodermata dominance index was 0.185 (Ngentup
Beach) and 0.515 (Banyu Meneng Beach). The Echinodermata abundance
index was 0.042 in Tripneustes gratilla (Ngentup Beach) and 0.349 in
Ophiocoma scolopendrina (Banyu Meneng Beach) with a similarity value
of 0.387. Abiotic factor conditions at Ngentup Beach and Banyu Meneng
Beach include pH 7.8, salinity 32.59%, temperature 27.20C, and DO 5.2 ppm,
and at Banyu Meneng Beach pH 8.2, salinity 30.47%, 27.7 0C, and DO 5.57
ppm. The correlation test results showed a high correlation between
Ophiocoma scolopendrina and the abiotic factor pH, namely 0.845,
Echinothrix calamaris with the abiotic factors of salinity, Diadema
setosum with the temperature 0.807 and DO 0.961.
