Clustering Location Criteria for Seaweed (Kappaphycus alvarezii) Cultivation Based On Oceanographic Characters

Abstract

Aquatic oceanographic characters are a special feature of a waters, where these characters will support the quality of seaweed produced. Oceanographic characters that are closely related to K. alvarezii include geographical position, type of water substrate, temperature, current, pH, salinity, Disolved Oxygen (DO), nitrate and phosphate and sociological characteristics of the community. Therefore, a study is needed to determine the criteria for oceanographic characters that are suitable for the location of K. alvarezii so that it can be used as a reference for farmers K. alvarezii to pay more attention to oceanographic characters in cultivating K. alvarezii. This study begins with observations and measurements of oceanographic characters directly at the location of the study as well as taking water samples. This study uses secondary data to be included, namely a map of the current pattern and that obtained by using the arcGIS application. According to the results of the analysis that has been carried out, S1 group (highly suitable) in Padike waters with a weight of 16, S2 group (suitable) in Tonduk waters with a weight of <16, and group N (not suitable) in Lobuk and Palasa waters with a weight of <10.
