Abstract

Sago (Metroxylon sagu Rottb.) starch is one of potential sources of starch in Indonesia; however, it has not been widely used as industrial raw material for modified starch, such as maltodextrin, which has higher addedvalue than the native sago starch. The aim of this study was to develop the processing technology of maltodextrin production from sago starch using microwave irradiation. The addition of activated carbon had a significant effect on the sugar produced in the microwave-assisted hydrolysis. The longer the duration of microwave irradiation the higher the total dissolved solids in the filtrate, and the lower the pH values. The increase of the microwave power level from 550 to 770 W significantly affected sugar content of the hydrolysates. Suitable Dextrose Equivalent (DE) value of maltodextrin (?20) can be obtained after hydrolysis for 10 to 12 minutes at the power level of 550 W or 6 to 8 minutes at the power level of 770 W.

Abstract

Single and mix cultures of white-rot fungi Trametes versicolor and Pleurotus ostreatus has been applied onto sugarcane bagasse as a pretreatment process. The purpose of this research was to investigate the effect of single and mix cultures of white-rot fungi in lignin degradation while maintaining minimum loss of ?-cellulose of sugarcane bagasse. Single and mix cultures of white-rot fungi T. versicolor and P. ostreatus have been inoculated onto sugarcane bagasse which varied in 5%, 10%, and 15% (w/v) with inoculum comparison 1:1. After 4-week incubation, analysis was carried out on the content of extractives, lignin, ?-cellulose and hemicellulose. The result showed that 4-week incubation of single culture of P. ostreatus was more advantageous as a pretreatment method for sugarcane bagasse, with considerable number of lignin degradation (17,95%) and minimum loss of cellulose (11,00%) and hemicelluloses (5,75%). As with mix cultures, incubation period should have been reduced to prevent significant loss of cellulose and hemicellulose. Furthermore, with shorter incubation period, this biological pretreatment process will be more interesting and feasible for the industry.
