MORPHOLOGICAL APPEARANCE OF THE SEAWEED KAPPAPHYCUS ALVAREZII CULTURED IN DIFFERENT HABITATS AT ARUNGKEKEBudiman Yunus and Moh. Tauhid UmarAbstract The goal of this research was to explore the morphological appearance of the red seaweed Kappaphycus alvarezii when grown in three different coastal habitats, including morphology, growth and carrageenan content. It is hoped that the results will provide information of use in the management and culture of high quality seaweed. The research took place over three months (January - March 2016) at Arungkeke, Jeneponto District, in the coastal waters of the Flores Sea. Carrageenan content was analyzed in the Nutrition laboratory, Faculty of Agriculture, and the Marine Biology Laboratory, Faculty Marine Science and Fisheries, Hasanuddin University. The longline method was employed to culture seaweed in three different habitats (estuarine, seagrass meadows and coral reefs), using a Split Plot Design. Analysis of Variance (ANOVA) was used to analyze the data. The coral reef habitat gave the best results in terms of absolute growth, specific growth rate and carrageenan content, which were 35.14 g, 19.26 % and 9.88 % respectively. Morphological performance was also superior compared to the other two habitats, including thallus color and freedom from pests/disease.
