IPB Discover How Making Biodiesel from Waste Liquid Animal
Bio Fuel Biodiesel can be obtained in liquid waste containment of slaughterhouses and livestock wastewater. Researchers from the Bogor Agricultural Institute to prove it. They can obtain one liter of biodiesel crude oil per day from an average of 156 per square meter of area shelters.
Biodiesel is derived from microalgae, says Prof. Suprihatin, senior researcher at the Department of Agroindustrial Technology, Faculty of Agriculture, Bogor Agricultural University (IPB), in his office in Bogor, West Java.
Microalgae is a phytoplankton. Microalgae easily found in various waters. Various types of microalgae widely studied because fotosintesisnya ranks highest efficiency and the ability to produce oil (lipid) is high enough anyway.
Microalgae biomass formation process requires a nutrient (nutrients). These nutrients as fertilizer for plants. An abundance of nutrients can be obtained from slaughterhouse waste and animal husbandry.
"In principle, in any waters provided that absorb sunlight and contain enough nutrients can be grown microalgae," he said.
According to him, domestic waste from households in urban and water from agricultural land also contains many nutrients that are good for breed microalgae.
Quick harvest
Microalgae grow quite fast so it can quickly harvest biodiesel. From research Suprihatin and his colleagues, obtained three types of dominant microalgae grown in medium wastewater from the abattoir and farm. All three were Chlorella sp, Scenedesmus sp, and Ankistrodesmus sp.
"Microalgae began to flourish after the fourth day. Then enter the death phase after 12 days to 15 days, "said Suprihatin.
Suprihatin measure the concentration of the growth of microalgae biomass. In the medium waste from slaughterhouses found growing phase 400 milligrams per liter to the optimum to 1930 milligrams per liter.
In cattle waste medium, the initial concentration of microalgae measured 190 milligrams per liter and is able to develop the optimum up to 2130 milligrams per liter.
Productivity of microalgae was an average of 160 milligrams per liter per day for the media slaughterhouse waste. Then 130 milligrams per liter per day for livestock wastewater media.
For the record, microalgae are grown in ponds reservoirs with a depth of 0.2 meters.
According Suprihatin, the productivity of microalgae in the medium slaughterhouse waste to 32 grams per square meter per day. As for the medium farm wastes obtained the average productivity of microalgae by 26 grams per square meter per day. The allowance for the nutrient phosphorus (P) and nitrogen (N) of growing medium each about 0.32 grams per square meter per day and 3.2 grams per square meter per day.
At the same time occurred the binding of carbon dioxide by microalgae approximately 60 grams of carbon dioxide per square meter per day and release oxygen is 22 grams per square meter per day.
Suprihatin said carbon dioxide-consuming microalgae. Microalgae for mitigating global warming by reducing carbon dioxide emissions as much as possible.
From various data, the count value Suprihatin obtain an average of one liter of crude oil biodiesel can be harvested from an area of 156 square meters with 0.2 meters depth pool shelter.
No complicated
Suprihatin said from one liter of crude oil biodiesel can be produced 80 percent of oil biodiesel ready. The process of making biodiesel is not as complicated.
The initial steps is to identify and isolate microalgae. Microalgae Chlorella sp type most rapidly growing than the other two, Scenedesmus and Ankistrodesmus sp sp.
After entering the optimal growth phase, ready for harvest microalgae. Microalgae was filtered, dried, and extracted.
The results of extraction of crude oil that must be separated using the solvent hexane or diethyl ether. Further purification by transesterification process.
This transesterification converts free fatty acids into alkyl esters. Esterification reaction by reacting the crude oil microalgae with alcohol and the addition of acid catalyst.
Suitable catalysts, such as sulfuric acid, hydrochloric acid, organic sulfonic acids, or strong acid cation exchange resin.
"From the transesterification process crude oil by 80 percent this microalgae into biodiesel," said Suprihatin.
Suprihatin said, so far has not gained a real count of production value than the price of biodiesel to conventional diesel or diesel oil. The indication is still above the price of conventional oil.
"There are other advantages that are still to be reckoned with," said Suprihatin.
Another advantage, microalgae never compete with food production. Microalgae undergo a process of growth is very fast and capable mengonservasi water.
The initial investment for clean energy production is not high. But, all depend on the intention and determination to achieve these gains.

Green Energy in Indonesia are more likely Instead of Nuclear Energy
Green Energy in Indonesia are more likely Instead of Nuclear Energy
Development of renewable energy are currently more likely than nuclear power plants. During a visit to Japan last week, President Susilo Bambang Yudhoyono said Indonesia will not build nuclear power plants as long as there are other energy sources.
"President Yudhoyono is on the right track to choosing a power source other than nuclear power plants," said the Climate and Energy campaigner of Greenpeace Southeast Asia, Arif Fiyanto, in Jakarta.
Arif said the threat of nuclear danger is greater than the benefits. In contrast, renewable energy sources there is no threat. "This is a signal for the government to write off nuclear power development plans and immediately switch on the development of renewable energy sources such as geothermal, solar, and wind," he said.
Nuclear technology expert who has worked at the National Nuclear Energy Agency (Batan), Iwan Kurniawan, said, does not mean the construction of nuclear power plants instead of nuclear experts in the Batan will be unemployed. Nuclear technology still needs serious attention to improving the economy in agriculture and healthcare.
"The problem may be in the budget already allocated Rp 450 billion for the period 2011-2013 to study the location in the Pacific Islands and the socialization of nuclear power plants," said Iwan. Funds amounting to it is put down in Presidential Decree No. 5 of 2010 on National Medium Term Development Plan 2010-2014.
"The fund will be more beneficial to the development of nuclear technology research, including the possibility to develop the capability of producing nuclear power plant components such as casings of nuclear fuel," Iwan says

Volvo Electric Car Successfully Develops With Mileage 1000 KM For Once Charging Battery
Volvo Electric Car Successfully Develops With Mileage 1000 KM For Once Charging Battery
Volvo makes a new step with electric car development project "Range Extender" that is able to travel a distance of 1,000 km. This project conducted a Swedish car company because of the limitations of electric cars currently cruising ability is limited. Range Extender is the electric cars equipped with gasoline engines (motor fuel).
According to Volvo, the project received assistance from the Swedish Energy Agency and the European Union. For these three combinations Volve develop concepts and technologies expected to be conducted a trial in the first quarter of 2012.
"This suggests we become more focused in the development of electric cars. During the electric car has limitations, namely the price and size of the battery charge. As a result, be very limited mileage, depending on battery type and size. With the Range Extender, electric cars could effectively increase the distance thousands of miles, but can emissions below 50 g / km, "beber Derek Crabb, Vice President of Power Train Engineering Volvo Car Corporation.
The development brings together three leading technologies of different technologies, 3-cylinder gasoline engine assist electric motor turning the front wheels. All are equipped with a brake energy concept renegeration or brake energy regeneration.
Gasoline engine used can also be given the intake of ethanol (E85). Two concepts tested on the Volvo C30 Electric. For this Volvo must make modifications include reduced battery size so that the petrol engine and fuel tank could be installed without creating new problems.
Concept I: Relationship Series
Using an electric car the Volvo C30. For this use 3-cylinder gasoline engine powered 60 PS (945kW) placed in the rear trunk. Gas tank capacity of 40 liters.
Machine connected to the generator 40 kW. The resulting power is used to rotate the electric motor with a power 111 PS or (82 kW). Penggemudi can also select and use a generator to charge the battery.
In this way, the mileage is also increased when the battery is used to run the car. The total combined mileage is 1,000 km. If only Relying on pure battery energy, about 110 km.
Concept II: Parallel Relationships
Cars get power from the 3-cylinder engine placed behind the gas tank is also 40 liters. The difference with the first draft, this version of the power source is connected in parallel. It is used for turbo 190 PS petrol engine working rotating rear wheels through a 6-speed automatic transmission.
In this way, the efficiency of cars on the highway when it accelerated better. Because the power cars rely on electric power from batteries, gasoline engines are also generated through the generator. For the 40 kW generator is used.
Motor electric motor that is used to produce power 111 PS (82 kW). The second source was the driving force when combined will produce 300 PS and is expected to sprint from 0 -100 km / h in 6 seconds. Range Extender 1000 km, while the battery is only 75 km.
Concept III: V60 Parallel
In this concept, the whole package drive is the front (engine room). The electric motor is equipped with a 111 PS turbo gasoline engine that produces 140 kW of power, transmission otomatid 2-stage and 40 kW generators. Power from the gasoline engine drive the front wheels through a transmission and recharge the batteries when needed.
Up to speeds of 50 km / h, the car always use electrical power. Gasoline engine will work at high speed. In addition, the gasoline engine is also tasked to charge the battery when its energy is below the specified limits.
The battery is placed in the rear trunk and produces mileage of 50 km (energy from the battery alone). Larger tank capacity, 45 liters and is designed to use gasoline and ethanol. Total mileage of 1,000 km.
"Through three projects allows us evaluate the various possibilities Range Extender. Among other electric car C30 and V60 Plug-in Hybrids. The goal, pressing the carbon dioxide emissions without
compromising the needs, comfort and practicality of using the car, "says Derek Crabb.
Volvo is the most complete car manufacturers perform various tests on vehicles made, especially the security aspect. Well, regarding the company's intention to produce electric cars, namely C30 Electric, various tests were carried out.
One of the interesting tests and greatly affect the performance of the battery is cold temperatures. For that Volvo electric car test at minus 20 degrees Celsius. Apparently, according to the company, which made electric car can operate smoothly.
Described, the test temperatures below zero do because Volvo apply the same test criteria with conventional cars it makes. Especially for electric cars, some new test methods were developed so that part is tested to 200 items.
"We must ensure, C30 Electricity still works fine when run, parking and charge the battery on a variety of conditions, from normal to very cold temperatures and hot. Northern Sweden is the most fitting place to do the tests below zero degrees, "said Lennar Stegland, Director of Volvo Cars Special.
Volvo C30 tested with three temperature control system. First use of heating and cooling for the passenger. Second, the use of cooling and heating for the battery (if needed). Furthermore, the electric motor and the "electronic power" or electronic control cooled using water.
Bio-Ethanol Heating
In this test, Volvo says, managed to create innovative solutions, which makes heating without sacrificing battery performance (mileage). For this, Volvo uses bio-ethanol heater mounted on the car.
Tank used to carry 14.5 liter bio-ethanol.
Utilizing these heaters can also electricity from the battery. In electric mode, use immersion heaters, which warm air in cold temperatures. "Motorists can memogram and control the temperature control unit in accordance with the conditions of his journey. Heating ethanol is the basic mode. In this way mileage vehicles with batteries farther away. For short distances, can operate the temperature control system to obtain electrical energy from the battery, "explains Lennart Stegland.
Battery charging system with no wired or wireless (wireless), it could be without plugs or stekker for hybrid electric cars and plug-ins, car manufacturers are increasingly in demand world. If previously, Toyota has been proclaimed in collaboration with WiTricity (U.S.) to develop a wireless charging system, now turn to Volvo in collaboration with the Belgian company.
This method is considered more comfortable and enjoyable. Because the owner did not bother rolling up the cable car after filling or manarik when going to plug it into the socket. The latest version - is actually still in the stage of development - which will be filled car parked on the plate battery charger (charging plate) that is hidden under the floor or road surface.
Wireless charging developed in collaboration with Volvo Drive Flanders from Belgium - the system induction. With this system, electrical energy is transferred from the source to the car charger without cables. In this way, changes or modifications to the charging system in the car.
"The main target should be fun electric car owners," explains Johan Konnberg, project manager of the Division of Special Vehicles Volvo Car Corporation. In this project Volvo C30 uses electricity to dimofikasi first filling the system.
How it Works inductive charging, the charger plate implanted under the ground, eg below the surface of the road to the house or in the garage. Charger plate consists of a coil that generates a magnetic field when energized by electrical current.
Well, when the car is parked on it, the energy of the plate was transferred to without physical contact to coil "puller" induction on the car. Flows transferred in the form of alternating current (AC).
Later in the car, an electric current is converted into direct current (DC) through a converter to charge the battery. Special to the Volvo C30 Electric, reaching 24 kWh battery capacity, takes about an hour an hour and 20 minutes for full charge.
Added, Volvo will send 250 electric cars to selected customers in Europe in the second half of this year. This is a step to accelerate the use of electric cars to choose!

How to Make Biofuel from Newspapers and Magazines Used
How to Make Biofuel from Newspapers and Magazines Used
SOME scientists at Tulane University in New Orleans had perfected strains Clostiridium named TU-103. Microbe is the first of its kind capable of performing the synthesis of butanol from cellulose.
Microbes TU-103 can process various kinds of plants and plant products and turn it into butanol. In other words, these microbes have the ability that one of them able to turn a pile of old newspapers into fuel.
TU-103 was discovered by David Mullin, a professor in the department of molecular cell biology and Tulane University with a postdoctoral Harshad Velankan Hailee Rask and students who worked for over two years.
The team tested the microbes in the middle of bagasse, the fibrous waste material generated during harvesting.
"Cellulose exist everywhere: paper, grass, leaves, corncobs, corn stalks and agricultural waste. These items are available in a large scale because of the stem and ear of corn is generally discarded as waste, "said Mullin.
"The results of the present invention can produce bio-butanol at a cheaper cost that can save fuel costs per gallon. As a fuel, bio-butanol made from cellulose which dramatically lowers carbon dioxide emissions than gasoline and has a positive impact on waste landfills.
Compared to ethanol, butanol is a better product. It utilizes waste material from existing products. Not made from crops grown specifically to make bakar.Butanol material has an energy content that is almost equivalent to gasoline, but with much lower emissions.
Professor practitioners in the department of earth sciences and environmental Tulane University, Jeffrey Sigler said, "Biofuels such as butanol, is generally better for air quality than petrol. This material has a much cleaner burning. "
"If agricultural waste can be recovered into raw materials for biofuels, it seems this could be a very important step forward in reducing CO2 emissions from various types of fuels, while minimizing the impact of land use," he added.
Amazingly, butanol does not require special modification for use in combustion engines that exist today in order to function as a fuel. It is therefore natural that Mullin had great hopes on the TU-103 and butanol as a fuel of the future.

Google's arch of amusing had some aciculate words for Facebook while speaking Wednesday at a tech conference, area Google co-founder Sergey Brin aswell showed up as a abruptness guest.
Vic Gundotra, Google's top controlling for amusing products, and Brin talked mostly about the company's Google+ amusing arrangement during a altercation at the Web 2.0 Summit in San Francisco on Wednesday.
"We wish to do amusing in a way that is added like absolute life," Gundotra said. "So I anticipate you're traveling to see us demography a actual privacy-centered approach."
Conference adjudicator John Battelle asked Gundotra what he anticipation of "the accessible amusing graph" -- that is, Facebook.
"There is a acumen why every anticipation in your arch doesn't appear out of your mouth," Gundotra replied. "We do not accept in oversharing. We anticipate curation matters."
Brin alleged himself "not a actual amusing person," but -- shocker! -- "Google+ I instantly begin compelling."
Brin talked up Google+'s "Circles" feature, in which the network's 40 actor users can put their access into altered groups and accept with whom they'll allotment their activity.
"At aboriginal I begin Circles complicated, but now I adulation them," Brin said.
But not anybody loves Google+. Battelle asked about a leaked memo, acquaint in Google+ itself, in which aggregation architect Steve Yegge accidentally acquaint accessible complaints about the amusing arrangement and how it was launched -- and Google's administration style.
"I mean, we never like to see that," Gundotra said. "But it gave humans a appearance of what we do internally. Within the Google family, we are actual honest. And analytical about our efforts."
Google (GOOG, Fortune 500) didn't blaze Yegge, Gundotra said, abacus that the aggregation took the attitude that "the alfresco apple got a blink at what it's like to plan at Google."
Brin backward mostly quiet on the subject. "I didn't accomplish it accomplished the aboriginal 1,000 pages myself," he laughed.
Brin's new role: Brin, who stepped down from his role as Google admiral in January and is now artlessly "co-founder," said he's been blessed in his new atom and enjoys the adventitious to analyze "more abstruse work."
