PENGARUH KONSENTRASI LARUTAN PEMASAK PADA PROSES DELIGNIFIKASI ECENG GONDOK DENGAN PROSES ORGANOSOLV

Water hyacinth can be used as the paper-making material and processed further to be made into ethanol. Before processed further, water hyacinth should undergo the delignification or lignin removing process. Delignification process is conducted in several ways: mechanic, craft, and organosolv. This research aims to find out the concentration of ethanol cooking solution and acetate acid by using the sulfate acid catalyst in order to get the maximum result of cellulose in water hyacinth delignification process with organosolv process using a reactor batch equipped by the electricity stirrer , mantle heater and also the condenser . Based on the result conducted, the optimum condition was obtained in the water hyacinth delignification with organosolv process, that is, by using the ethanol cooking solution at 80% concentration with sulfate acid catalyst with pH 2 and cooking time of 2 hours.
