Abstract
This research purpose is to address growth performance of carrageenan-producing seaweeds of Kappaphycus and Eucheuma. The research was conducted in coastal area of Kaung Island, Buer sub-district, Sumbawa Regency from August to September 2012. Importance of Eucheuma/Kappaphycus spp. for Indonesian economy and farmer livelihood are main source of hydrocolloids and main source of income. West Nusa Tenggara is one of the production center for Eucheuma/Kappaphycus in Indonesia. The method used for this study was planting seaweed using long-line system involving 25 farmers. The species planted were Kappaphycus alvarezii Tembalang, Kappaphycus alvarezii Maumere, Kappaphycus striatum and Eucheuma spinosum. The growth of Eucheuma spp was measured every 7 days until harvesting time which is 45 days. Initial seed weight was 100 g and the number of seeds perline were 200. Purphoses sampling done by 5 samples per line for analysis of fresh weight, dry weight, carragenan content and incident disease.The result of this research shows that the increase in weight Kappaphycus alvarezii Tembalang is 0,82 grams/day, Kappaphycus alvarezii Maumere is 0,06 grams/day, whereas that of Kappaphycus striatum is 0,97 grams/day and Eucheuma spinosum is 5,59 grams/day. It can be concluded that K. alvarezii, K. striatum and E. spinosum can grow in Kaung, E. spinosum is more adaptable to Kaung ecology, and can be grown throughout the year.
