Kappaphycus striatus, a member of the Rhodophyta class, is extensively farmed by the coastal residents of Kupang, East Nusa Tenggara. The objective of this study was to examine the development and productivity of seaweed by the application of liquid organic fertilizer (LOF) using both floating net cages and the longline method. The data analysis was conducted via a factorial full random analysis approach. The findings indicated that the mean values of absolute growth, relative growth, daily growth rate, and production associated with the floating net cage method were 11.91± 0.80g/ day, 0.032± 0.002g/ g/ day, 3.14± 0.17%/ day, and 16.19± 1.08gdw/ m, respectively. Regarding the longline approach, the values obtained were 9.48± 2.09g/ day, 0.027± 0.004g/ g/ day, 2.65± 0.43%/ day, and 12.89± 2.84gdw/ m, respectively. The growth and output of seaweed can be influenced indirectly by the quality of water. The statistical analysis revealed a significant difference (P< 0.01) in the effect of seaweed cultivation when comparing the cultivation method with the LOF treatment.
