PRODUKSI DAN KARAKTERISASI BIOCHAR AMPAS TEBU(Saccharum officinarum Linn) PRODUCTION AND CHARATERIZATION OF BAGASSE BIOCHAR (Saccharum officinarum Linn)

The production and characterization of bagasse biochar (Saccharum officinarum Linn) in this study was carried out through pyrolysis for 4 hours at a temperature of 1100C. The purpose of this research was to determine the biochar capacity of bagasse (Saccharum officinarum Linn) as an ameliorant for improving fertility in marginal lands, especially in West Kalimantan, namely peatlands. The capacity of biochar as an ameliorant in this study is known based on gravimetric analysis, which has a moisture content of 0.38%, ash content of 2.42%, volatile content of 0.53%, fixed carbon (cf) 97.02%. Meanwhile, from the results of SEM-EDX characterization there were 100% carbon compounds and the presence of pores in the form of micro pores. And the results of FTIR characterization have the absorption of functional groups of organic compounds at wave numbers (cm-1) 3448.72 from the Ogroup OH streching, 2978.09 and 2931.80 CH bending groups of cellulose compounds, 2368.59 and 2276 C≡C bending groups lingnin compounds and 1620.21 and 1435.04 groups of C=O and C=C streching compounds of lingninsellulose and hemicellulose
