ABSTRAK

Penelitian ini bertujuan untuk menentukan pengaruh hidrolisis selulosa hasil delignifikasi tandan kosong kelapa sawit dan menentukan kondisi terbaik hidrolisis yang didapatkan pada proses hidrolisis dalam sistem cairan ionik kolin klorid. Bahan baku utama yang digunakan adalah selulosa hasil delignifikasi TKKS, kolin klorid, asam sulfatl, dan aquadest. Penelitian ini dilakukan pada temperatur 105oC, konsentrasi katalis (H2SO4)10 % (b/b) selulosa, jumlah cairan

ionik 10%, 15%, dan 20% (b/b) selulosa dan kecepatan pengaduk konstan 120 rpm dengan waktu reaksi 30, 60 dan 90 menit. Hasil penelitian pada tahap hidrolisis menggunakan cairan ionik diperoleh kadar glukosa. Analisis dengan metode LUFF menunjukkan kadar glukosa maksimum yang dihasilkan yaitu sebesar 37,96% dengan kondisi terbaik pada waktu reaksi 90 menit dan jumlah kolin klorid 20%.

ABSTRACT

This research aims to determine the hydrolysis of delignification results on palm empty fruit bunches and determine the best conditions of hydrolysis obtained in the hydrolysis process in the choline chloride ionic liquid system. The main raw material used is cellulose delignification results TKKS, choline chloride, sulfatl acid, and distilled water. The hydrolysis stage in this research was carried out at temperature 105 0C, concentration of catalyst (H2SO4) 10% (w / w) cellulose, the

amount of ionic liquid 10%, 15%, and 20% (w / w) cellulose and it was stirred at constant speed 120 rpm with a reaction time of 30, 60 and 90 minutes. The results showed, in the hydrolysis stage was obtained using an ionic liquid glucose . LUFF method analysis showed the purity of the resulting hydrolysis is equal to of 37.96% with the best reaction time, the optimum conditions was obtained in reaction time 90 minutes and the amount of choline chloride 20%.
