Abstract
Tourism in West Nusa Tenggara Province has experienced a significant increase in tourist visits so that the community and the government are interested in managing tourism more professionally. Tourism management will lead to the use of coastal and marine land, with no regard to the causal effectiveness or the ecological impact of the building materials used, one of which is macroalgae. This study aims to determine the type of macroalgae, to know the media that are overgrown with macroalgae, and to find out the comparison of types in three ecosystems in the Sekotong Coastal Area, West Lombok. This research was conducted from January to June 2018. The study was a kind of descriptive experimental by using purposive sampling method. Identification of the type of macroalgae was carried out by taking into account the morphological structure including the shape of the thallus, the color of the thallus, the form of thallus branching, the form of branching of spores and the arrangement of cells. Data analysis was conducted by calculating the relative density (KR), relative frequency (FR), and important value index (INP). The types of macroalgae found were 35 species are belongs to the three divisions, namely Chlorophyta (8 types), Rhodophyta (21 types), and Phaeophyta (6 types). The type of Sphacelaria novae Hollande found is abundant with an INP value of almost 200%. Media that is overgrown with macroalgae is wood and tile media. While the rubber media and concrete are slightly overgrown with macroalgae. Ecosystems that are mostly found in macroalgae are in seagrass ecosystems with 33 species while mangrove ecosystems are slightly overgrown with macroalgae with 13 species.
