The results of the study found 4 types of seagrass that were spread fairly evenly at 3 research stations, namely: Enhalus acoroides, Thalasia hemprichii, Cymodocea serulata, and Cymodocea rotundata. The range of the average coverage percentage is between 12,50% – 14,96%. Seagrass density ranges from 164,40 – 196,52 ind/m 2 with the highest composition, and species density was Thalasia hemprichii and the lowest was Cymodocea rotundata.
