Abstract: Activated carbon is believed to reduce radiation from cell-phone because it has large pores. This study aims to synthesize a silica-carbon composite as a mobile phone casing using activated carbon from bamboo, coconut shells, and coal combined with silicone rubber. The addition of activated carbon is carried out in the range of 10 - 30 g. Activated carbon mixed with silicone rubber and stirred for 3 minutes at 150 rpm. Based on Digital Electromagnetic Radiation, the highest addition of activated carbon (30g) provides a high radiation reduction but has a small tensile strength and a large elongation value. SEM images show that the distribution of activated carbon 10 - 15 g is more homogeneous on the mobile phone casing.
