THE EFFECTIVENESS OF THE USE OF MORINGA OLEIFERA AND EICHORNIA CRASSIPES ACTIVATED COAGULANT SEEDS IN THE PROCESS OF CANAL WASTE WATER CLEANING IN MAKASSARAndi Haslinah, Andrie Andrie, Fatmawati and Djuarti MD
The processing of natural coagulant materials into something that can provide a wider benefit and a greater contribution to society. This study aims to determine the combination of coagulants that are effective in reducing pH and turbidity in domestic wastewater. This research begins with taking Moringa oleifera and Eichhornia crassipes, making coagulants from these two materials, then taking the wastewater after that prepare a stirrer, the two coagulants are put in a beaker glass then the solution is stirred at 180 rpm for 2 minutes using a mixer, then stirring again at 40 rpm for 15 minutes. The solution is allowed to stand for 20 minutes until 2 layers are formed, after which the filtrate and sediment are separated with filter paper (filter membrane) then turbidity and pH measurements are carried out. The effectiveness of each treatment using the percentage change (% change). The results obtained were for the largest decrease in pH was found in Moringa oleifera of 6.880 then followed by combination 1 and combination 4. As for Turbidity, the increase occurred in the treatment of combination 2 to combination 6, and the decrease in turbidity in the treatment of Eichhornia crassipes, combination 1, and Moringa oleifera, namely 1,050 NTU; 1,120 NTU and 1,760 NTU. The conclusion is the effectiveness of the combination of coagulants between Moringa oleifera and Eichhornia crassipes for pH and Turbidity is a combination of 1 (10 + 10) mg.
