Abstract

This study aims to determine the effect of different doses of urea fertilizer on the growth of seaweed (Caulerpa lentillifera). The research utilized a Completely Randomized Design (CRD) with four treatments and three replications: treatment A (control without urea fertilizer application at 0 mg/L), treatment B (urea fertilizer application at 27 mg/L), treatment C (urea fertilizer application at 47 mg/L), and treatment D (urea fertilizer application at 67 mg/L). The parameters tested were absolute growth rate and specific growth rate. Data analysis was conducted using ANOVA. Seaweed (Caulerpa lentillifera) specimens, with an average weight of 200 g (totaling 2,400 g), each of 200 g samples were placed in aquariums sized 40x40x35 cm and maintained for 35 days. The absolute growth rate obtained for treatment A (without fertilizer application) was -111 g, for Treatment D was -115 g, for treatment C was -129.3 g, and the lowest was observed for treatment B at -135.7 g. The specific growth rate obtained for treatment A (without fertilizer application) was -2.68 g, for treatment D was -2.74 g, for treatment C was -3.00 g, and the lowest was observed for treatment B at -3.28 g. Based on the results of the ANOVA test, it can be concluded that the addition of urea fertilizer at different doses did not have a significant effect (P>0.05) on the absolute growth rate and specific growth rate of the seaweed (Caulerpa lentillifera).
