Rice straw Where is cellulose material is silicone sanfiorik nilai plant by acid to produce pipeline by studying the relevant factors that affect digestion 2 factor was the concentration of the acid sanfiorik 0.5, 1.0, 1.5, and 2% w/v and the quantity of rice straw in the aqueous solution of acid equal to 2.5, 5.0, 7.5% (w/v) to take the time to degrade, 15:00?T 121° c temperature Which found that the appropriate conditions for digestion is the concentration of the acid sanfiorik 2% (w/v) and the quantity of rice straw in aqueous solution of acid equal to 7.5% (w/v), the maximum quantity of pipeline equals 38.52 (g/L) by measuring the quantity of sugar vs. standard glucose graph (phenolic-sanfiorik method). Bring the pipeline that is increasing the appropriate use of ethanol fermentation by Saccharomyces cerevisiae yeast TISTR 5049 by State is divided into 3 (1) the quantity of sugar started with different nitrogen sources, (2), (3) proper APA charoem appropriate by curing the underlying temperature 30° c for a period of 5 days, Saccharomyces cerevisiae, it was found that TISTR 5049 can fuel ethanol fermented from pipeline has been highest in day 3 the concentration of sugar, starting with 25% (w/v) ammonium sulphate 0.10% (w/v) and p.a. charoem ton is equal to the quantity of ethanol which is lathao with 75.336 (g/L).
