Abstract. The result of this research is to determine the ratio of the combination of cow manure and bagasse (F/I) to the volume of biogas production, chemical pretreatment effect of raw material bagasse on biogas production volume and the effect of co-digester on biogas production. The results showed a decrease in total solid occurs when the increase of 2%, 5% to 10%, and this contributes to decreasing the production of biogas. Chemical pretreatment influences on the production of biogas through pretreatment with 2% NaOH solution with surface morphology bagasse seen with SEM image and its chemical structure changes with FTIR instrument. The highest biogas yield of 51.04 L/Kg substrate was obtained from a combination bagasse treated with 2% NaOH solution for 24 hours and as much as 20% cow's rumen.

“…Possibly, the failure in finding reducing sugars from alkaline pretreatments was mainly due to how they produce swelling of cellulose, but not necessarily reaching hydrolysis of reducing sugars present or their chemical composition changes [26]. Although the applications of basic pretreatment with CaO, basic pretreatment with NaOH, oxidizing basic pretreatment, and ozonolysis are effective because they improve the opening of cellulosic fibers [10], they do not degrade sugars at this stage, that is, only making the material susceptible to enzymatic attack.…”

The objective of this study was to evaluate the chemical and enzymatic hydrolysis using a factorial experimental design (2 3 ) in order to obtain fermentable sugars from cellulose-based material (CBM) usually used as pet litter. In assessing chemical hydrolysis, we studied the effect of temperature, in addition to H 2 SO 4 concentration and reaction time, on the production of total sugars, reducing sugars, soluble lignin, carbohydrate profile, furfural (F), and hydroxymethyl furfural (HMF). We performed a response surface analysis and found that, at 100 ∘ C, 1% acid concentration, and 60 min reaction time, the yields of 0.0033 g reducing sugar/g biomass and 0.0852 g total sugars/g biomass were obtained. Under the above conditions, F is not generated, while HMF is generated in such a concentration that does not inhibit fermentation. We pretreated the CBM with H 2 SO 4 , NaOH, CaO, or ozonolysis, in order to evaluate the effectiveness of the enzymatic hydrolysis from the pretreated biomass, using an enzymatic cocktail. Results showed that CBM with acid was susceptible to enzymatic attack, obtaining a concentration of 0.1570 g reducing sugars/g biomass and 0.3798 g total sugars/g biomass. We concluded that acid pretreatment was the best to obtain fermentable sugars from CBM.

“…Substrate (bintaro fruit powders) immersion was done in 1L 1N NaOH at 100°C and 1 bar pressure for 30-minutes holding time in an autoclave in accordance with the research conducted previously by [4]. On the completion of the delignification process, the substrate was rinsed for several times using distilled water in order to neutralize the pH of the solution.…”

Abstract. Bintaro fruit (Cerbera manghas) contains 36.945 of cellulose and 38% of lignin which is potential as a source of raw material for making bioethanol. The purpose of this research is to know the effectiveness of formula in producing bioethanol by the process of bintaro. The methods used in this research are pretreatment, delignification, hydrolysis, fermentation, and distillation. Pretreatment was performed by subcooling the substrate at 80 0 C followed by milling it up to 60 mesh. Delignification was performed by soaking the substrate in 100 0 C of 1N NaOH and 1 barr for 30 minutes. Hydrolysis was carried out with sulfuric acid catalyst (H2SO4) variations of 5.5%, 6.0%, and 6.5% at 120 0 C for 60 minutes. Fermentation with Zymomonas in variation of 1%, 3%, and 5% at room temperature for 3 days. The fermented filtrate was distilled at 73 0 C to obtain ethanol and tested the levels of ethanol with chromatography gas. The results showed that the highest levels of ethanol is 9.977% resulted from 6.5% of sulfuric acid hydrolysis and 5% of Zymomonas mobilis fermentation. The high levels of ethanol is supported by qualitative test result of the presence of reducing sugars with fehling yielding of 7002 ppm red brick tested quantitatively by nelson somogyi method. In conclusion, the level of bioethanol produced is directly proportional to the increased concentration of sulfuric acid and Zymomonas mobilis. The conclusion is levels of bioethanol produced is directly proportional to the increase in the concentration of sulfuric acid and Zymomonas mobilis is used.
