Determination and Classification of Benthic Habitat With Lyzenga Algorithm in Tanjung Piayu Waters, Riau Islands

Batam Island has topographical characteristics including elevation, and coastal ecosystems that are considered complete include coral reefs, macroalgae, seagrasses, and mangroves. Tanjung Piayu waters are found in the southern part of Batam Island, which is adjacent to the Barelang bridge that connects the other islands to Batam. The water of Tanjung Piayu have the potential to develop into a marine tourism hub, saltwater fish farming, fishing, and many more. In this study, the classification and correction of water columns were carried out using the Lyzenga formula, to see benthic habitats in the waters of Tanjung Piayu. This research uses a remote sensing method with Landsat-8 image data. This study purpose was to determine and classify the distribution of benthic habitats in the waters of Tanjung Piayu. The results of this study obtained four classes in the classification of shallow-water benthic habitats with an area of coral reefs 199.50 Ha, seagrass and sand 496.90 Ha, land 2987.18 Ha, and waters 1603.97 Ha, and with the percentage of coral reefs 3.77%, Seagrass and Sand 8.88%, and waters 30.33%. The Lyzenga algorithm is able to identify benthic habitats and determine the area size according to the class in benthic habitats.
