Abstract
This study aimed to analyze the differences strains in the characteristics of the specific growth rate Kappaphycus alvarezii . This research was conducted in the waters of Lontar village, Serang Banten for 45 days in May-June. The treatment used is a strain difference seaweed seedlings derived from tissue culture (KJL-Lampung), strain “ Jumbo kuning coklat ” (JKC-Lontar) and strain “ Jumbo hijau botol ” (JHB Taman Jaya). This study used an experimental method using a completely randomized design (CRD) with three treatments and each 3 replication. Culture method of seaweed used off-bottom methode. Parameters measured were the specific growth rate and water quality. The results showed that the specific growth rate in seaweed Kappaphycus alvarezii strain JHB-Taman Jaya higher than the specific growth rate of seaweed Kappaphycus alvarezii strain JKC-Lontar and KJL-Lampung. Therefore, for maintenance in May-June should be planted seaweed Kappaphycus alvarezii strain JHB-Taman Jaya.
