“…However, the linear effects of NaOH concentration and the interactive effects of NaOH concentration and microwave power were not significant (P > 0.1), which shows that these terms had little influence on reducing sugar yield. Wang et al [22] have observed low solid recovery and reduced sugar yield on using alkali concentration above 3% for pretreatment with long exposure to microwave energy in coastal Bermuda grass. In this study, the insignificant effect of NaOH concentration on reducing sugar yield reveals that alkali concentration below 3% does not affect the sugar yield.…”

“…Pretreated cassava pulp showed highest reducing sugar yield of 472.61 mg g 21 (microwave alkali) and 309.84 mg g 21 (microwave acid) with 100 W of microwave power on 30-min exposure. Further increase in microwave power leads to decrease in reducing sugar yield, which might be due to degradation of carbohydrates at higher temperature as well [22].…”

In the present study, a comparison of two types of microwave pretreatment such as microwave assisted alkali and microwave assisted acid were studied using cassava pulp as the substrate. The effect of pretreatment agent concentration, microwave power and pretreatment time on enzymatic saccharification was studied using a response surface method according to Central Composite design. Under optimized conditions, microwave assisted alkali pretreatment of cassava pulp with 2.27% NaOH at 125 W for 18 min followed by enzymatic hydrolysis gave reducing sugar yield of 0.472 g g 21 dry biomass, while microwave assisted acid treatment with 1.95% H 2 SO 4 at 135 W for 25 min showed reducing sugar yield of 0.306 g g 21 dry biomass. The yield from microwave assisted alkali was higher and was 2.7 times higher than that obtained with raw cassava pulp. Microwave assisted liquefaction of pretreated cassava pulp at 100 W for 30 min using amylase lowered the process time.

“…Generally this pretreatment is conducted under low temperature conditions with long time and high base concentrations [14]. The advantage of using a base as a lignocellulose pretreatment is the presence of lignin destruction wherein lignin inhibits the action of the enzyme during the anaerobic process [15]. Alkali can damage ester bonds between lignin and xylem [16].…”

Abstract. Food needs in Indonesia is increasing, including beef. Today, Indonesia has problem to do selfsufficiency in beef. The cause of the problem is the quality of local beef is still lower compared with imported beef due to the quality of livestock feed consumed. To increase the quality of livestock is through pretreatment and fermentation. Source of livestock feed that processed is solid sago waste (Arenga microcarpa), because in Indonesia that is relatively abundant and not used optimally. Chemical pretreatment process for delignification is by using NaOH solution. The purposes of this research are to study NaOH pretreatment, the addition of Trichoderma sp, and fermentation time to improve the quality of sago solid waste as livestock feed through anaerobic fermentation. The variables used are addition or without addition (4%w NaOH solution and Trichoderma sp 1%w) and fermentation time (7, 14 and 21 days), with the response of crude fiber and protein. The result of this research shows that the pretreatment with soaking of NaOH solution, addition of Trichoderma sp and 14 days of fermentation was more effective to improve the quality of solid sago waste with decrease of crude fiber from 33.37% to 17.36% and increase of crude protein from 4.00% to 7.96%.
