PENGARUH PERENDAMAN BERBAGAI DOSIS PUPUK BIONIK TERHADAP LAJU PERTUMBUHAN RUMPUT LAUT Gracilaria Verrucosa

ABSTRACT

This study aims to determine the effect of immersion in various doses of bionic fertilizer on the growth rate of Gracilaria verrucosa seaweed. The test organism used was Gracilaria verrucosa Seaweed. The research design used was a completely randomized design (CRD) with 4 treatments and 5 replications in order to obtain 20 experimental units. The treatment in this study was immersion of liquid bionic fertilizer for 6 hours with the following doses: (0 ml), (2.5 ml), (3.5 ml), and (4.5 ml). The results showed that the immersion treatment of bionic liquid fertilizer on the growth of G. verrucosa seaweed showed a very significant effect (P <0.01) on the specific growth rate and the growth in absolute weight. Treatment (dose 3.5 ml) gave the best results at a specific growth rate of 0.95% / day and an absolute weight growth of 57.26 g.
