Abstract
Cengar natural clay has been used as precursor for synthesis of liquid coagulant. Liquid
coagulant was used to improve the quality of peat water into clean water. Liquid
coagulant was obtained through calcination stage of clay at a temperature of 700 °C for
1 hour and leaching using 0,2 mol H2SO4 with various temperatures of 80 and 100 °C
for 2 hours. Further peat water parameters before and after the coagulation was analyzed
including turbidity and TSS. The results showed that the coagulant with leaching
temperature 80 °C (KLC 1(80-2)) achieved highest percentage efficiency for turbidity
17.59% and TSS 62,78%. However, peat water after the coagulation is unsuitable with
