ASOSIASI ECHINODERMATA DENGAN KOMUNITAS PADANG LAMUN DI PERAIRAN DESA MANGON KECAMATAN SANANA KABUPATEN KEPULAUAN SULA

Abstract

The purpose of this study was to determine the association between the phylum Echinodermata and the seagrass community in the waters of Mangon Village. This research was conducted in the waters of Mangon Village, Sanana District, Sula Islands Regency in October 2022. The research method used was the quadratic transect method. This method consists of 2 research stations which are about 500m apart. The transect line is drawn straight from the beach to the sea for 100m then a quadratic plot is placed in a zig-zag manner to the left and right of the transect line. There were 10 plots that were observed and spaced 10m each and 3 repetitions were carried out with a distance of 50m per transect. From this method the results obtained in the waters of Mangon Village showed that at station one, the species found at two stations in Mangon Village waters were 7 species of Echinodermata and 6 species of seagrass. Based on the person product moment correlation value, there is a correlation in the form of a positive association between seagrasses and echinoderms at the study site. The environmental parameters owned by the waters of Mangon Village, Sula Islands Regency, namely, temperature has a range of 24-28˚C, salinity has a range of 28 – 34⁰/00, and pH has a range of 7,08-8,08. The substrate obtained is sand and sand mixed with coral fragments.
