Abstract

Seagrass were flowering plants that grow entirely under the sea. Seagrass were a significant element in coastal habitats such as Bintan waters because it acts as a protective beach. Seagrasses have the capacity to stabilize the bottom waters of sediments and were able to generate sediments that can fertilize the waters. Seagrass can be a reference in coastal area to improve the stability of the coastal environment. Seagrass beds are useful for a protected area for tiny organisms a spawning location for aquatic biota and a location for juvenile and larval enlargement. Distribution of seagrass abundance are essential to understand because they can define coastal regions whether they are harmed or not. Seagrass surveillance techniques were still using divers with restricted coverage of the study region. For this reason an acoustic method was used through this research to detect seagrass and the habitats that it occupied. It can be concluded that the acoustic method can measure sound intensity or acoustic backscatter from seagrass and their habitat. The height of the seagrass can be evaluated depending on the acoustic reflection value of the seagrass. There were 3 seagrass groups based on percent closure in the research place which were tiny to none of the seagrass groups unusual seagrass groups and many seagrass groups. Seagrass was mostly found in good sedimentary habitats. The increase in the quantity of manually calculated seagrass biomass was accompanied by a rise in the value of acoustic backscattering intensity. The overall accuracy of the seagrass species using the acoustic technique is 87.
