Rice and Rasi (by the name food processed from cassava in indonesia) of course differs in but it’s the function is same, as staple food. Rice made from rice material, while Rasi from cassava material. If Rice consumed by some of Indonesia publics, while Rasi only consumed by a few people in Kampung Cirendeu, Leuwigajah, Cimahi Town, West Java.
When during Rice new order becomes favorite as component of staple food, many member of certain publics - as in Papua with habit eats corms, Gunung Kidul eats tiwul and other - changes over to rice. Hence, at that time, recognized term people or member remain to is told is poor if has not eaten rice.
But, member of public Kampung Cirendeu non imbued with of the mention, they remain to maintains habit which they to inherit hereditary, eats Rasi. And, the tradition had been acted the kampong ancestor since a period of colonization of Dutch 1918. But happened change of term from initial Sanguen becomes Rasi.
The story, by 1924 the doyens Kampung Cirendeu assess name of Sanguen doesn't be national, hence changed to to become Rasi. Actually, the the kampong ancestors doesn't refuse rice, but they have history which do not benefit with morning crop.
At one time, in colonization epoch of Dutch, area of rice field which has been cultivated abrupt paddy to run dry. very Difficult rice supply at that time and member of kampong started looks for way out from this problem, by changing rice field to become cassava garden area. And, since then public Cirendeu familiarizes consumes cassava.
Stands at bay eating Rasi
Exploiting of Extract Cassava for tooth impression material mixture
In impression material Indonesia alginate many applied circle medical of tooth although still must be imported from outside country. Since economics crisis the year 1998 the price of increasing alginate impression material until four times at that moment.
This situation resulted in efforts to modify the commercial alginate as had been conducted by a dentist in South Sumatera province in Indonesia.
He who had added cassava starch into the commercial alginate used to make partial denture impression. The aim of this research is to investigate the effect of additional cassava starch into the commercial alginate on its ability to produce reproduction detail using type III gypsum the amont of 120 specimens were divided into 6 group of various additional cassava starch 45–55%.
The specimens then being impressed with detail reproduction tool (ISO No. : 1563/1978) and the result is then analyzed under a stereo microscope. Conclusion: the alginate impression material with cassava starch with ratio up to 47,5% can be used as an impression in 50μm and 75μm in depth line
Many talked about ethanol
Many people will not know fuel from Ethanol, have never been thought of a root crop to have components for this ethanol fuel.
Recently, a plant express $40million to yield ethanol from cassava which have been expostulated among general public.
For the agriculture industry, this ethanol production could mean greater employment opportunities for cassava farmers while in economic terms, the increasing produce in cassava farming for ethanol production could boost the country's Gross Domestic Product.
Nevertheless, produce of ethanol fuel earns even exported to boost the relation of international trades, idea to change cassava into ethanol fuel, or into likelier fuel, be a miracle.
It is best known as the alcohol found in thermometers and alcoholic beverages. It is often referred to as alcohol. However, in more simple terms, ethanol fuel is fuel derived from the decomposition of the organic compounds of ethyl alcohol. Ethanol is also known as ethyl alcohol, drinking alcohol or grain alcohol. After the use of fire, the fermentation of sugar into ethanol is perhaps the earliest organic reaction known to humanity. Fermentation simply means the process of culturing yeast under conditions to produce alcohol.
Newest visit a delegation of commerce from country China with ambassador Fiji Sir James Ah Koy has caused reaction where some people has received this initiative as an encouragement for country while the other sees this thing like having an environmental destruction influence especially in heating global.
However, knows that this thing which is idea amazing to make cassava becomes ethanol fuel to draw and really fascinates.
Bio-fuel engineer in Biofuel Unit in Department from Energy Vilimone Vosarogo says idea to yield ethanol fuel started at Brazil August 1971.
He says this is because of commodity exchange incorporated surplus un-sellable a real big from which they start reducing ethanol for fuel from commodity exchange incorporated.
Mr Vosarogo says some nations in area Pacific Asia like Thailand, Malaysia, Country China and Indonesia has in the process of yields ethanol fuel from cassava.
He says Fiji is ideal country to produce this because of climate that enabling produce of high energy yield like cassava.
"The economy will save a big percentage from the Annual Fuel Input bill and foreign exchange earnings," Mr Vosarogo said.
"That will yield on the ground is made cash flow with purchasing on the ground yields fuel and about courses there will be a a real big rural worker market as thing which the main suppliers at this ethanol fuel plant.
"There will be also one improvement to present indiscreetly contributes sector, independence lessened in social prosperity, reduced pressure from science and in an a real short repays time, a a real return height for plant from this $40 million in four years," he says.
"Actually, there will be a downdraft of Greenhouse gas emissions.
"Which is effective decay factor and strongest in lessening global warmness.
"This is the best way to refer good area and expansion responsible.
"Fiji under no obligation to give a cent for repair from program but for downstream is of benefit, that becomes is better to have control from its(the product and consumption," he says.
"This is why a joint venture with farmers is necessary though some kind of arrangement"
Mr Vosarogo said to turn cassava into ethanol fuel, the cassava must first be fermented with a catalyst.
He said this goes through a distillation process and after further controlled distillations, ethanol fuel is produced which has to be below 0.5 per cent water content to be engine compliant for full combustion and vehicle maintenance.
He said the suppliers of cassava were open to the general public of Fiji.
"In fact, it is deliberately priced lower than the current market price to address the issue of an increase in prices of cassava for local consumption.
"The factory will buy at 30 cents a kilo compared to around 50 cents per kilo in the market.
"However, idea to yield ethanol fuel from cassava to refer national energy crisis because fuel costs rising, reduction oil fuel back up, global trend to look for alternative fuel, manipulation near by nations OPEC to improve repair condition of climates and a reduction of Greenhouse gas emissions"
Mr Vosarogo had earlier stated that over $1.2billion was spent on importing fuel last year.
He said there were more than 80,000 cars in Fiji where 67 per cent of these would be able to use ethanol directly.
He said all cars made after 1992 and most imported cars could also use ethanol.
He said ethanol production was not just for land transport but also for sea, air and generators.
In modern times, ethanol was intended for industrial use but later its production from by-products of petroleum refining has become more popular.
Ethanol has an extensive use as a solvent for substances intended for human contact or consumption including scents, flavorings, colorings and medicine. Ethanol is an essential solvent and a feedstock for the synthesis of other products. Its toxicity to yeast limits the ethanol concentration obtainable by brewing.
The fermentation process must exclude oxygen. In order to produce ethanol from starchy materials, the starch must first be converted into sugars.
The largest single use of ethanol is as a motor fuel and fuel additive while the largest national fuel ethanol industries exist in Brazil.
