Abstract
The purpose of this study is to determine the effect of Ulva sp extract for Kappaphycus alvarezii, and to determine the dosage. This research is expected to provide benefits for seaweed farmers in increasing production. This research was conducted in August 1st until October 30, 2016, at Ekas Bay, Ekas Buana village, Jerowaru sub-district, East Lombok. The study design used a completely randomized design (CRD), there are six treatments with four replications, so the number of experimental units totalling are 24 experimental units. Data were analyzed using ANOVA (Analysis of Variance) and conducted a further test LSD (Least Significant Difference) if there is a significant effect of each treatment. The results showed that the extract of Ulva sp. have a significant influence on the specific growth rate and absolute growth of Kappaphycus alvarezii. The higest specific growth rate is 5.48% from the treatment 30% dosage Ulva sp extract. The highest absolute growth is the treatment with a concentration of 30% with an average weight of 498.5 grams. The conclusion of this research is extracts of Ulva sp. significantly affect Kappapycus alvarezii growth and optimal dose for growth Kappapycus alvarezii is 30%.
