Dewaka's banana grows well and abundant bananas production in Merauke area, but with a little bit sour taste when they're ripe made this bananas often the second choice compared to another kind of bananas. The research has been conducted to determine concentration of bioethanol produced from dewaka's banana flour. Banana flour was obtained from crused the slices of dried bananas. Then concentration of ethanol can then be identified through a series of tests in the laboratory. The results of gas chromatographic analysis show that dewaka banana can be used as an alternative energy source with bioethanol content of 83.43%. The concentration was result of 5 (five) days fermentation with yeast. The hydrolysis which is used was acid hydrolysis, using hydrochloric acid. The optimum concentration of hydrolysis was 1.5 N HCl, the optimum temperature was 90 0 C, whereas the optimum hydrolysis time was 70 minutes.
The purpose of the study was to determine the quality of the grainand rice are planted, the ricevarieties Inpago Unsoed 1. The research method use dis data collection, namely primary data andsecondary data. Primary data is used for observed in this research about grain moisturecontent,density of grain, foreign bodies, empty grains, grain crackedor broken, after the percentage ofgrain milled head of rice, broken rice, graing roats, grain limestone, yolk broken and milled rice yield.The results showed that during the observation the quality of grain varieties Inpago Unsoed 1 hasmilled at about 13,33% moisture content, grain density of 0,57g/ml, and grain weight is 27,60g/1000grain. The percentage point for the determination quality of head point is 73,49%, broken grainsabout 13,92%, and 12,34% graing roats. The quality of rice milled varieties inpago Unsoed 1 includelow. The lower of rice quality is due to the low of head rice percentage, while the percentage ofbroken grain sand high graing roats. Rice milled yield about 51,23%
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
