Mineral Content Seaweed Gracilaria Verrucosa Fertilized using Vermicompost
Journal Title: GRD Journal for Engineering - Year 2017, Vol 2, Issue 9
Abstract
Seaweed as chlorophyll plants requires nutrients to support growth. Vermicompost is 100% organic fertilizer quality and environmentally friendly, contains of various nutrients needed for seaweed to grow and produce optimal levels of agar and play an important role in stimulating the vegetative growth of seaweed. The purpose of this study is to determine the optimal dose of vermicompost fertilizer to produce the content of mineral elements such as NO3, NH4, PO4, SO4 and Mg seaweed. From the results of the Kolmogorov Smirnov (KS) and Shapiro-Wilk (SW) norms, the mineral content of seaweed in the form of nitrate (NO3), ammonium (NH4), phosphate (PO4) and sulfate (SO4) spread following normal distribution (p> 0.05). Levene homogenity test of mineral content of NO3, NH4, PO4 and SO4 have the same homogenity has been fulfilled (p> 0.05). The mineral content of nitrate (NO3), phosphate (PO4), magnesium (Mg) and sulfate (SO4) seaweed Gracilaria verrucosa the highest obtained in treatment A and the lowest in treatment F while the highest mineral content of ammonium (NH4) seaweed at treatment C and the lowest on the treatment F (without fertilizer).
