Abstract

This study aims to analyze the relationship between water quality variables with the growth of seaweed(Gracilaria verrucosa).Maintenance seaweed conducted in selected farms for 42 days, the weight of the seaweed as much as 50 g wet tied with a rope vertically. Variables observed were not free (y) the specific growth while independent variables are (x) the intensity of light, salinity, temperature, degree of acidity, nitrate, phosphate, ammonium, iron and magnesium. Data were analyzed using multiple regression was used to determine independent variables obtained is used to predict the dependent variable. The results showed that the water quality of the 9 variables that were examined was only five variables, namely water quality nitrate, salinity, iron, ammonium and phosphate which significantly affect the growth of seaweed (G. verrucosa) in the pond.
