Abstract

Seagrasses are flowering plants (angiosperms) that live on a substrate of sand, muddy sand, and sand mixed with coral fragments. Seagrass beds have an important role both for supports the life of various types of marine biota as well as protein source for the coastal community. The purposes of this study were to find out the types of seagrasses and to assess seagrass bed conditions around Lantung village waters. The line transect quadrat method was using for data collection. Four transects were laid perpendicular from the sea to the shoreline. A 50 x 50 cm frame was used to asstimet seagrass percent cover and laid every ten meters along the transect line. This study found 7 species of seagrass namely Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, Syringodium isoetifolium, Halodule pinifolia, Halophila decipiens, and Halophila ovalis. The average value of seagrass percent cover at the location was 66.44% and it was categorized as ‘healthy’. The environmental parameters values were 29.86°C, 29.05‰ and 8.45 for temperature, salinity and pH respectively.
