Abstract:
Moringa seeds can be utilized as coagulants because they contain active substances of 4α-4r-rhamnosyloxy-benzyl-isothiocyanate. The purpose of this study was to determine the effectiveness of Moringa oleifera seed as coagulant in reducing fluoride content and turbidity in well water. The fluoride and turbidity was monitored by UV-Vis spectrophotometry and turbidimetry, respectively. The result showed that moringa oleifera seed, is able to reduce fluoride content and turbidity. Fluoride content in Purnama village, Sukajadi village and Tanjung Palas village percentage decrease of fluoride content equal to 49.10%, 24.97% and 28.94. Turbidity value in Purnama village, Sukajadi village and Tanjung Palas village percentage of turbidity degradation value equal to 62.06%, 60.51% and 19.05%. Based on PERMENKES RI NO. 416 of 1990 on the terms of supervision of clean water threshold value for fluoride 1.5 mg/L, while from the results of this study obtained by 0.0082, 0.1908 and 0.1591 mg/L. For the turbidity value of 25 NTU, while from the results of this study amounted to 23.8, 10.16 and 41.93 NTU.
It can be conclude that moringa oleifera seed effective in lowering fluoride content and turbidity in dug well water.
