Abstract:
Moringa oleifera is one of the plants that is easy to find and cultivate. This study was conducted to see the effectiveness of moringa seeds in well water treatment as a natural coagulant to replace coagulant from chemicals that have less beneficial effect. This research was conducted on well water samples in Rumbai Pesisir sub-district Pekanbaru in three different urban villages with total hardness and coloredness parameter and some insitu parameter. Moringa seeds reduced the highest total hardness by 47.05% in Limbungan Village, for the color parameter can be reduced by 83.82% in the Lembah Damai Village. The result of some parameters of DHL can be reduced by 18.64% in Lembah Sari, TSS by 30.82%, turbidity by 43.48%, for temperature parameter and pH moringa seed dust did not give significant change. Based on paired t test (P=0.05), moringa seed dust is effective to decrease total hardness, color, DHL, TSS, and turbidity contents. Based on KEPMENKES RI No: 416/MENKES/PER/IX/1990 on the requirements and supervision of clean water quality and PERMENKES RI No: 492/MENKES/PER/IV/2010 regarding drinking water quality, known total hardness, temperature, pH, TSS meet the value requirements of water quality and drinking water but turbidity and color was known to exceeds the value of water quality and drinking water requirements
