N2 - One of the biomass lignocellulose derived from Empty Bunches of Palm Oil (EFB) has great potential as a source of biofuel because of its cellulose content reaches 40% of the total weight, the amount of abundant in Indonesia reached 31 million tons in 2019, and its utilization is still very limited. This study aims to find out the optimum condition for reducing sugar production after enzymatic hydrolysis using cellulase enzymes from Aspergillus niger and Trichoderma ressei (1:2). EFB that have been sieved measuring 100 mesh is delignified using a mixture of NaOH 2% and H2O2 5% at 70oC for 6 hours. Then, the process was continued by enzymatic hydrolysis at pH 5,5 condition and stirring speed of 125rpm. Variables used are temperatures (oC) 30, 40, and 60; substrates (gr) 1, 2, 3; and hydrolysis time (hours) 24, 36, and 48. The optimal operating condition (substrate ratio, temperature, and hydrolysis time) was studied using the Response Surface Methodology (RSM). The resulting R2 value is quite high at 95.59% and 91.62% for R2(adj). The highest concentration of reduced sugar (14.29 g/L) was achieved from the model developed at 37°C, a 3gr mass of EFB per 10 cm3water, and 24 hours hydrolysis.
