Production Of Activated Charcoal From Bagasse Waste To Reduce Grounding Resistance Of High Voltage Overhead Power Line

Abstract

Bagasse waste contains 0.79% ash, 27.90% pentose, 22.09% lignin, 37.65% cellulose and 2.0% essence (alcohol, benzene). The cellulose content can be made into active charcoal. The purpose of this study is to determine the effect of time and temperature of bagasse pyrolysis on reducing the grounding resistance value of high voltage overhead power line (SUTT). The bagasse samples were pyrolised at temperature variations of 600oC, 700oC, 800oC, 900oC, and 1000oC, for the duration of 30 minutes, 60 minutes, 90 minutes, 120 minutes, and 150 minutes. The activated charcoal samples were then mixed with NaCl with ratio of 0:1; 0.25:0.75; 0.5:0.5; 0.75:0.25; and 1:0 before being planted under transmission tower. The optimum characteristics of activated carbon were obtained in pyrolysis for 149.8 minutes at 992.05oC, with a characteristic value of 20.79% yield, 14.2% ash content, 1.71% moisture content, 83.71% fixed carbon, 2.09% volatile matter and 1142.1 mg/g iod absorption. These characteristics of activated charcoal meet the standards of activated carbon SNI 06-3730-1995. The results of data analysis show that the activated charcoal : NaCl ratio of 1:0 can reduce the value of SUTT grounding resistance by 76.26%
