The most of seaweeds farmers in Geger Coast use off-bottom method. But there are some farmers try to use the new method, the cage method. Nobody knows the cage method can give the higher result of production than off-bottom method or not. To know that is usefull to do the research for compare the both of methods, thus finally based on the both methods can be knew what is the better method to get more result.
The research was conducted to know daily growth rate of K. alvarezii that planted by cage and off-bottom methods. The research was conducted during six weeks, between January and March at Geger Coast, Nusa Dua, Bali. Geger is choosen because the coast has many potential area for cultivation of seaweeds and until now has been used to cultivation of seaweeds, especially for K. alvarezii. The seaweed used in this research is K. alvarezii. The method that used in this research is experimental method. Data was obtained by measurement of growth from K. alvarezii.
Generally the result showed that cultivation method was given significantly different (sig. < 0,05) to daily growth rate of K. alvarezii. The highest daily grow rate of K. alvarezii was given by off-bottom method at second week at 6,32 ± 0,71%. Whereas the lowest daily grow rate of K. alvarezii was given by cage method at sixth week at 0,84 ± 0,81 %.
