Mount Sinabung volcanic ash is a basic material that can be used to produce silicon dioxide (SiO 2 ). SiO 2 can be used as a building raw material as well as in food and beverage packaging. To produce SiO 2 , the volcanic ash of Mount Sinabung must be synthesized using the coprecipitation method. The result of this process produces SiO 2 content as much as 48%, a formed function group that states the existence of SiO 2 namely Si-O-Si and Si-O at absorption of 1095.57 cm-1 and 798.53 cm-1. From the results of SEM can be seen the morphology of SiO 2 formed. In the XRD results, the phase of SiO 2 is amorphous.
