Abstract

This research is a continuation of the previous research on optimizing Ipomoea batatas L. leaf extract as a flocculent in water treatment for practicum on the chemistry of environmental analysis. This study will be carried out through two stages, the first step is to optimize the optimal processing parameters. Secondly it is water treatment using optimal processing parameters, followed by testing hardness in the water sample before and after processing for hardness testing using the EDTA titration method with the EBT indicator. The results showed the optimal parameters of water treatment with Ipomoea batatas L leaf extract as flocculent was pH 7.17, coagulant dose 8 mL, flocculent dose 3mL, stirring coagulant speed 200 rpm for 7.5 minutes, and flocculent stirring speed 30 rpm for 10 minutes. The results indicate Ipomoea batatas L. leaf extract as a flocculent in water treatment can also reduce the total hardness level in the water.
