        abstract = {The study of reflux time variation influence for zeolite synthesis using 
hydrothermal method from bottom ash coal burning residu of P.G. Madukismo
Yogyakarta has done. 
Convertion process of bottom ash into zeolite has four phases: Preparation,
refluxing in HCl (reflux time variation 5, 6, 7, 8, and 9 hours), zeolite synthesis
and characterization. The product of zeolite synthesis is characterized by XRD
and FTIR. 
Product of this synthesis is zeolite type Faujasit, Zeolite Y, Zeolite X, Zeolite
Na, and Zeolite ZSM-5. The result of FTIR characterization showed that the
pattern adsorption of double ring of zeolite at 560,31-617,65 cm
. Reflux time
influence the type and christalinity of zeolite synthesis product because refluxing
can also cause an Al decreasing and dealumination..


Key word: Zeolite, Bottom Ash, Reflux}
