<![CDATA[The purpose of this research is to identify the effect of pyrolysis and drying on coconut shell charcoal proximate analysis. The method used in this research is Taguchi method. The independent variables used in this study were pyrolysis temperature (4500C, 5500C and 6500C), residence time (60 minutes, 90 minutes and 120 minutes), drying temperature (1000C, 1050C and 1100C) and drying time (12 hours, 18 hours and 24 hours). The response variable in this research is coconut shell charcoal proksimat value consisting of moisture content, ash content, volatile substance and bound carbon content. Orthogonal array used is L9(3)4. The results showed that the optimum condition for moisture content obtained in A1B1C1D1 condition means pyrolysis temperature 4500C, residence time 60 minutes, drying temperature 1000C and 12 hours drying time. The optimum condition for ash content obtained in A2B3C2D1 condition means pyrolysis temperature 5500C, residence time 120 minutes, drying temperature 1000C and 18 hours drying time. The optimum conditions for volatile substances obtained in A3B3C2D1 condition mean pyrolysis temperature 6500C, residence time 120 min, drying temperature 1050C and 12 hours drying time. The optimum conditions for the bonded carbon content obtained under A3B3C2D1 conditions mean pyrolysis temperature 6500C, residence time 120 min, drying temperature 1050C and 12 hours drying time.]]>
