The Use of Moringa Seed (Moringa oleifera) Extract as a Natural Coagulant to Reduce the Turbidity Level of Worongnge Village River Water

Abstract

The quality of the water used by the community in Worongnge Village is poor water quality, therefore alternative solutions are needed to treat water so that the water is suitable for use. One process that can be used is the coagulation-flocculation process with Moringa seeds. The purpose of this study was to determine the concentration of Moringa seeds can stabilize the quality of water pH, TDS, and turbidity (turbidity) of river water in Worongnge Village. This research was conducted in the form of an experiment consisting of 5 treatments and each treatment used 1 liter of river water and each would be given 3 variations of time: (12 hours, 24 hours, 36 hours). The design is as follows: P0: 1 liter of river water without treatment P1: Provision of 1 liter of river water and 2 g of Moringa seed extract. P2: Giving 1 liter of river water and 4 grams of Moringa seed extract. P3: Giving 1 liter of river water and 6 grams of Moringa seed extract. P4: Giving 1 liter of river water and 8 grams of Moringa seed extract. The results of the research carried out found that the effective concentration of Moringa seed extract was 2gr(P1) where the results were water pH 7.2, water TDS 0.191, and turbidity (turbidity) 46. The use of Moringa oleifera seed extract as a natural coagulant is effective in reducing the turbidity of river water.
