Abstract

SYNTHESIS OF SUGAR FROM ORGANIC WASTES VIA ACID CATALYST
HYDROLYSIS. Hydrolysis process is an important step from every process to produce biofuel with
organic wastes as raw material. Hydrolysis process with chemical uses hydrochloride acid as catalyst
in which will transform holocellulose to glucose. Raw material of 100 grams is put into hydrolysis
reactor with batch system equipped with pressure control and ratio hydrochloride of 1 : 6 w/v. The
variables studied were temperature of 110-140oC, HCl concentration of 0.5-1%, time of hydrolysis of
15-60 minutes. The sugar concentration was taken and then be analyzed by Nelson-Somogy method.
The hydrolysis, which was carried out with the temperature of 120oC, time of 30 minutes, HCl
concentration of 0.75%, and the pressure of 6 bar, produced sugar reduction of 27.3 mg/mL and yield
of 15.07%.

Proses hidrolisis merupakan satu tahap penting dari rangkaian tahapan proses produksi bahan bakar
nabati menggunakan bahan baku sampah organik. Proses hidrolisis secara kimiawi menggunakan
HCl sebagai katalis akan mengubah holoselulosa yang terdapat pada sampah organik menjadi gula.
Gula yang dihasilkan inilah yang dapat difermentasi menjadi bahan bakar nabati. Bahan
baku sebanyak 100 g dimasukkan dalam reaktor hidrolisis sistem batch yang dilengkapi dengan
pengukur tekanan dan ditambahkan larutan HCl pada perbandingan 1:6 b/v. Hidrolisis dilakukan
dengan memvariasikan suhu operasi 100-140oC, waktu proses 15-60 menit, serta konsentrasi HCl 0,5-
1%. Hidrolisat yang dihasilkan dianalisis kadar gula menggunakan metode Nelson-somogy. Hasil
hidrolisis yang dilakukan pada suhu 120oC selama 30 menit serta konsentrasi HCl 0,75% dan tekanan
terukur 6 bar menghasilkan gula 27,30 mg/mL dan yield gula sebesar 15,07%.
