Abstract

This research purposes are to increase the production of seaweed species Eucheuma or Kappaphycus spp. adaptive to changes in water conditions and to produce high quality of seaweed continuosly accepted by industry troughout the year. In order to achieve these objectives, suitability analysis of Eucheuma or Kappaphycus spp using different cultivation methods and the stimulation of the growth of Eucheuma or Kappaphycus spp by adding Sargassum aquifolium extract was carried out. The research method used was the application of an integrated action research and involvement of farmers who will implement the research purposes directly. The result shows that the combined use of Eucheuma or Kappaphycus spp. and method of cultivation significantly affects the absolute growth of Eucheuma or Kappaphycus spp. and content of carrageenan. The other results of this research shows that the application of Sargassum aquifolium extract has no effect on the growth of Kappaphycus alvarezii. The conclusion of this research is the best growth of Eucheuma spinosum is found in cultivation using longline method, the best growth Kappaphycus striatum is found in cultivation using bottom-off method, and the best growth Kappaphycus alvarezii is found in cultivation using raft method. The application of Sargassum aquifolium extract does not have a significant effect on the growth of Kappaphycus alvarezii but can increase level of carrageenan content.
