Gadjah Mada University (UGM) Research Team Develop Ganyong for Bio-ethanol production. For some people, rimpang ganyong (Canna edulis ker) is seen next to the eye so that less dibudidayakan. Rimpang that during the time known only as a distraction or food flour wheat flour substitute, also appeared to be used as alternative fuel for gasoline and kerosene.
This was after the UGM Research Team to develop bio-ethanol production from rimpang kana as one of the hydrogen fuel. "Interest from ganyong, this plant has not been much dibudidayakan and have great potential. Substance because it contains starch that is hig
h enough, gulanya high enough, so have the potential for bio-ethanol.
Ganyong, the plant is easy to grow, tolerant of shade, have a potential high enough to developed, "said Dr. Kumala Dewi, M.Sc., a member of the research team in 25 exhibition Results Activities Research and UGM Hi-Link Project at the Sheraton Hotel Jakarta, Tuesday (4 / 3). UGM Research Team Develop Ganyong for Bio-ethanol Production Kumala Dewi addition, researchers are Prof.. Dra. Endang Sutariningsih Soetarto, M.Sc., Ph.D., both of them is a lecturer at the Faculty of Biology Gadjah Mada University, and Prof.. Dra. Wega Trisunaryanti, M.S., Ph.D. UGM's Faculty of Mathematics and Natural Sciences.
In research, the bio-ethanol production is done in a way take advantage of dry starch in ganyong that reach 15-20 percent. Gynecology and starch hydrolysis dirombak the union to become a more simple process Liquefaction Saccharification. "With the union a more simple, the more glucose chain length, we cut into pieces so that it becomes a simple form of sugar. Next fermented leavened with the help of the usual used as yeast bread, "said women's birth Magelang, 8 April 1966 this.
Fermentation carried out during the next 3-4 days. Results include alcohol fermentation. However, the alcohol content will increase sharply during the fermentation process lasts up to 40 percent on the day keeempat. Results ago didestilasi fermentation process for the purification. Destilasi obtained from the first bio-ethanol with the 50-75 percent level. Next, re-done destilasi to obtain bio-ethanol with a value above 90 percent. "After that bio-ethanol can dimurnikan using molecular sieves," said Kumala Dewi more.
From this research, the quality level of bio-ethanol can be 98 percent meet the standards of fuel substitution. The maximum concentration recommended for mixing bio-ethanol with 98 percent gasoline, is 10 percent. Mentioned in the research, a kilogram (kg) ganyong can produce 120 cc of bio-ethanol. This means that 7-8 kg ganyong needed to produce one liter of bio-ethanol. In other words, the comparison of 8:1 is required to be able to produce bio-ethanol berkadar 75 percent of the comparison and 12:1 for bioethanol berkadar 97-98 percent. Kumala Dewi with other members of the team conducting the research since July 2008 after obtaining grants from the Hi-Link.
The idea to utilize ganyong obtaining 1993. At the time he conducted the research culture ganyong. "There I find that ganyong easy to grow and can be manipulated umbinya formation such that production of many more. But kan, utilization not know that much. In addition to food, because it contains starch and sugar so I have ideas to develop as bio-ethanol, "said the mother of three children. (PR UGM / Gusti Grehenson)
