ABSTRACT
Research on river water treatment has been carried out using the coagulation-flocculation method by using of natural coagulants. Soybeans can be used as natural coagulants because they contain protein, and the results obtained will be compared with PAC coagulants. The purpose of this study was to determine the efficiency of using soybeans for turbidity and TDS removal in river water, to compare the results of using soybeans as a coagulant with PAC coagulants and to calculate SVI and sludge mass values. Soybeans were prepared by drying in the sun for 7 days and sifting with a sieve size of 140 mesh. The coagulation-flocculation process was carried out using a jar test with fast stirring at 100 rpm for 1 minute, slow stirring at 40 rpm for 20 minutes, with varying doses of soybeans, namely 180 mg/l, 190 mg/l, 200 mg/l, 210 mg/l, 220 mg/l and variations in PAC doses, namely 15 mg/l, 20 mg/l, 25 mg/l, 30 mg/l, 35 mg/l. Soybean coagulant and PAC have almost the same effectiveness in reducing turbidity, organic matter and color. Where the turbidity reduction efficiency for soybean coagulant is 93% and 94% PAC, for removal of organic matter in soybean coagulant is 38.94% and PAC 42.37%, then for removal of color content of soybean coagulant is 38.24% and PAC 44, 12%. For SVI and sludge mass values, soybean coagulant and PAC also have almost the same effectiveness. As for the TDS parameter, due to the more soluble nature of the PAC coagulant, makes it easier to react so that it forms flocs quickly compared to soybean coagulants. Where the results of the TDS concentration increased at a dose of 220 mg/l, namely 185 mg/l so that the TDS efficiency was -46.83%.
