Potensi Kulit Kacang Tanah (Arachis hypogaea) Sebagai Sumber Karbon Untuk Material Maju

Abstract

Carbon material is one example of the development of advanced materials. Carbon is the result of the decomposition of an organic compound through an imperfect carbonization process. Carbon can be utilized from organic waste materials containing cellulose, hemicellulose, lignin and starch. The composition of peanut shells is 65.7% cellulose, the high content of cellulose in peanut shells makes it a potential carbon source. The method used for the manufacture of peanut shell carbon is calcination at various temperatures of 250 ⁰C, 300 ⁰C, 350 ⁰C and 400 ⁰C. Carbon proximate analysis was carried out by testing the ash content, vapor content and bound carbon content. In this study the standard used is SNI 06-3730-1995. The results of the analysis showed that the ash content increased with increasing calcination temperature, while the vapor content decreased with increasing calcination temperature. The carbon content obtained decreases with increasing calcination temperature. The optimum condition of peanut shell carbon close to SNI 06-3730-1995 was obtained at carbon with a calcination temperature of 250 ⁰C, 5.10% and a vapor content of 7.41% and a bound carbon content of 87.49%.
