The effectiveness of banana stem juice as a natural coagulant for treatment of turbid water was investigated. The main parameter studied was Turbidity. Coagulation experiments using jar test was performed with a flocculation system where the effects of Turbid Water pH, Retention time as well as Dosage of Banana Stem Juice on coagulation was examined. A Three Level Factorial Design in Response Surface Methodology (RSM) using Design Expert software was applied in the model analysis. Consequently, most of the actual and predicted values closely agreed with various regression coefficients. The characteristics of the Turbid water was determined with TSS at 222 mg/L, turbidity at 143 NTU and COD at 89.36 mg/L, BOD at 44.68 mg/L, DO1 at 11.7 mg/L, DO5 at 6.93 mg/L, pH at 7, Temperature at 27.3°C. Turbidity reduction using Banana Stem Juice was achieved at pH 6.5 with percentage
