Abstract
The Talaud Archipelago is one of the Regions in North Sulawesi with natural materials such as white sand which is very potential. The purpose of this study was to identify the mineral content and to determine the characteristics of silica extracted using the alkaline fusion method on the white sands of Sara Beach and the White Sands of the Talaud Islands. The analysis used is FTIR (Fourier Transform Infra Red). The results of the FTIR analysis show that the spectrum results that often appear in the wave number 680-850 cm-1 which is indicated as a symmetric stretching vibration function group of Si-O in siloxane (=Si-O-Si=), wave number 1800-1600 cm-1 which is the –OH bending vibrational functional group of Silanol (Si-OH).
