Abstract
Kappaphycus alvarezii seaweed is one of the important economically valuable commodities. Kappaphycus alvarezii is one of the macro algae species that has many benefits. Kappaphycus alvarezii seaweed cultivation is the dominant mariculture activity on Panggang Island, DKI Jakarta. The condition of the quality of the aquatic environment greatly affects the production of Kappaphycus alvarezii seaweed. This study aims to analyze the suitability level of Kappaphycus alvarezii seaweed cultivation in the dry season and rainy season. This research was carried out in Panggang Island, DKI Jakarta during the dry and rainy seasons. The observed environmental quality parameters include the physical physics parameters, namely temperature, current speed, brightness, and depth observed in situ. Aquatic chemical parameters namely salinity, pH, dissolved oxygen observed in situ and nitrates and phosphate observed in ex-situ. In order to get a classification of the suitability level, the suitability of the marine matrix is made through scoring and weighting on the parameters limiting seaweed farming activities. Based on the results of the study it can be concluded that the suitability of the waters on Panggang Island, DKI Jakarta is very suitable (Sl) for Kappaphycus alvarezii cultivation both during the planting period in the dry season or the rainy season.
