Abstract

Coagulation and flocculation process is always ended up with sedimentation process. The success of settling process depends on quantity of settled floc. Appropriate concentration, pH, and velocity become important factors for the performance of the coagulant. Moringa oleifera is organic coagulant, cheap, and easy to produce it. Settled floc has been observed the biomass, and lipid ingredient for its potency as biodiesel. The aims of this research were to determine the influence of concentration, pH and flocculation speed, rapid mixing time variation on the results of biomass and lipid harvesting using Moringa oleifera as coagulant in Bozem Morokrembangan. Jar tests experiment were carried out at different concentrations of Moringa oleifera of 0- 100 mg/L and pH variation were 4.5-6.5. The next step was to determine the optimum variation of the flocculation speeds were 0-50 rpm. Data analysis in this research was descriptive analysis presented with graphs, as well as statistical analysis using Anova One-Way test. The optimum coagulant concentration with Moringa oleifera for harvesting biomass and lipid of sediment was obtained in this study of 60 mg/L and pH 6.5. The optimum speed of flocculation was obtained in this study at 0 rpm of rapid mixing is optimum for settling flocculation using M. oleifera.
