The objective of this study was to explore the capacity of the coagulation active agent that extracted from Moringa oleifera (MO) by various solutions for turbidity and hardness removal in raw water sources. The extracted active agent was also characterized base on its functional group analysis. The solutions of NaCl, KCl and distilled water were used for the active agent extraction. Solution of KCl 1.0 N showed better removal capacity for turbidity and hardness in raw water in compared to NaCl 1.0 N and distilled water. The functional group characterization by FTIR for the residual precipitate after extraction indicated that the order of N-H and C=O bond removal for the following solution is: KCl 1.0 > NaCl 1.0 > distilled water. The result showed that the higher removal capacity of KCl than other solutions was determined by peptides concentration, which is represented by N-H and C=O bond content in the solution.
