HUBUNGAN PAPARAN GELOMBANG DAN ARUS TERHADAP KONDISI LAMUN DI PULAU BADI, KABUPATEN PANGKAJENE KEPULAUAN

Badi Island is one of the small islands in the Spermonde Islands. Badi Island is
also located in the wave exposure zone in the Spermonde archipelago and these
conditions affect seagrass growth. This research was conducted from June to December
2022 on Badi Island. The purpose of this study was to determine the relationship
between the level of exposure to waves and currents on the presence and condition of
seagrass beds on Badi Island. The use of this research is that it can be a source of
information and as a reference in research related to the distribution of seagrass beds
on Badi Island, as well as for the purpose of managing the biological resources of the
Spermonde Islands. The research location is divided into 4 stations namely station 1
(North), station 2 (East), station 3 (Southwest), and station 4 (West) where this station is
the control station. Seagrass data were collected using a 50 cm x 50 cm quadrant
transect along the line transect and measurements of physical oceanographic factors
such as currents, waves, wind, tides, depth, and substrate were also carried out.
The results showed that there were 6 types of seagrass found in Badi Island
waters, namely Thalassia hemprichii, Cymodocea rotundata, Halodule uninervis,
Halophila ovalis, Enhalus acoroides, and Syringodium isoetifolium. High waves on the
west side of the island can be one of the factors causing the low seagrass density and
cover on Badi Island. Although the slow current speed on Badi Island does not have a
major effect on the presence of seagrass.
