Abstract

Gracilaria is one type of producing agar (agarofit) seaweed which is widely found in Indonesian waters. Agar contain gelatin-based hydrocolide compounds commonly used as thickening agents in the food industry. Differences in initial biomass and spacing significantly affect the growth of seaweed. This is related to the competition of each individual seaweed in getting nutrients. The success of the planting system is influenced by the use of good quality of seeds and the appropriate weight will increase the growth. The aim of this research is to know the influence of seed weight and spacing to the specific growth of seaweed Gracilaria verrucosa  by using vertical rope method. The experimental design used was Factorial Design, where factor A (weight of seed 50 g, 100 g, and 150 g) and factor B (spacing of 20 cm, 30 cm and 40 cm). The observed variable is the specific growth rate. The result of ANOVA showed that the difference of seed weight and spacing significantly influenced (P <0.01) the growth of G. verrucosa. The highest specific growth was found on seed weight of 50 g,  5.4% day-1 and 30 cm seed distance factor of 4.2% day-1.
