Abstract
Cultivation of Kappaphycus alvarezii with the long line method is not fully effective because in certain seasons of extreme weather its production decreases due to loss of thallus during cultivation. This study aims to determine the performance of Kappaphycus alvarezii cultivation using local seed and tissue culture seeds methods with different spacing. The experimental design used was a factorial completely randomized design, in which there were factor A (different seeds) and factor B (different spacing). Based on the results of the study, the average DGR of K. alvarezii with different seed origins in each treatment at different distances, there was no difference. The results showed that the extreme weather factor of waves affected the growth of seaweed because in the planting season from May to July the waves and waves were very strong. Therefore, the long line cultivation method is not feasible to be applied to improve the performance of seaweed cultivation.
