LPG Fuel for Motorcycles
Posted on | April 21, 2010 | No Comments
Automotive enthusiasts who know a lot of LPG can be replaced when the gasoline engine runs like a motorcycle. The result will be more economical and environmentally friendly. However, the facts are still too few people who dared to apply it.
“If you do not know the technique, LPG cylinder for motorcycle fuel could explode and harm others around him”, said Budi Soelaiman Sunarto, founder of the Business Multipurpose Cooperative (KSU) Agro Makmur, Karanganyar regency, Central Java.
Currently LPG in containers the size of three kilograms of small tubes is very easy to find. But, still not so many people are familiar with gasoline to LPG conversion techniques to running motorcycle engine.
Since 1998, Budi formed the company in the village of Agro Makmur Doplang, Karangpandan, Karanganyar District. He developed an environmentally friendly energy technology-based ethanol and bio-methane or biogas. Equipped also making its production facilities, such as biogas tool to convert waste consumption of dry organic waste into methane or facilities for the use of bio-ethanol with fuel-efficient stoves ethanol.

According to expert biomedical, Suprapto Ma’at, just screening of tropical herbs of anti-HIV often committed developed countries like the U.S. or Europe. Screening was preceded by the determination sitotoksisitas of cell culture extracts that have been infected by HIV, to screen for the fraction of plant extracts which are known to have a steady activity as anti-HIV.

As reported the nation’s leading newspapers, Kompas. Indonesia Boscha observatory located in Lembang, Bandung, West Java now has a new facility in the form of sun glasses. Lembang is located in tropical areas and enough to make a pretty good strategy to study the sun.
NASA already has a SOHO (Solar & Heliospheric Observatory), certainly not balanced when compared to existing solar telescope in the Boscha. However, due to the strategic location and close enough to the center of Bandung. This is very good facilities to attract people, especially students.
Looking ahead, the data from this solar telescope will be connected with live streaming on the ITB’s website and updated in real time. This data would be used for the National Institute of Aeronautics and Space (LAPAN).

Bioethanol, Potential Future Energy
Posted on | November 11, 2009 | No Comments
According to the researchers, as a country rich in agricultural production and plantation, Indonesia has the potential to develop bioethanol as a gasoline substitute. Even in the future, conversion into bioethanol fuel can be a solution to the depletion of oil content.
Bioethanol can be an option in reducing environmental damage as a side effect of the development of industry and transportation. There are several advantages possessed bioethanol fuel than gasoline, partly because the production process more environmentally friendly and involved planting vegetation that absorb carbondioxide in the atmosphere. In addition, the using of bioethanol as fuel for motor vehicles more environmental friendly because it produces less pollution. Read more
Using of Detergent in Indonesia

For other cleaning materials, detergents is the yield of technological advances that make use of the chemical byproduct of petroleum distillation, combined with other chemicals such as phosphate, silicate, dye, and fragrance ingredients. around in the 1960s, the early generations detergent appeared using surface pengaktif chemicals (surfactants) Alkyl Benzene Sulfonat (ABS) is capable of producing foam. However, due to the difficult nature of ABS broken down by microorganisms in the soil surface, eventually replaced by Linear Alkyl compounds Sulfonat (LAS) are believed to be relatively more familiar with the environment.
In many countries in the world have banned the use of ABS and replaced with the LAS. While in Indonesia, the regulations concerning the prohibition of using ABS does not exist. Several reasons ABS is used in detergent products, such as low cost, stability in the form of cream / pasta and abundant foam. Read more
Solar Cycle Miracle

The sun on the way its evolution as a star shows the dynamic properties, both in the outer layer (photosphere, chromosphere, corona) and the inner lining. One of the wonders of evolution behavior is the phenomenon of solar activity cycle 11 years.
Iteration cycle is a common event in nature. Afternoon changed the night, due to the earth’s rotation on its axis. Successive seasons due to the slope of the earth’s rotation axis to the plane of its orbit around the sun (the earth’s equator at an angle of 23.5 degrees to the Ecliptic). And the sun was also a cycle of activity.
Various period solar cycle have been identified, both within the tens or hundreds of years. One of the easily observed is the 11-year activity cycle. This phenomenon has even been known to observers of the sun since the 17th century, considering the method used is simple, namely counting the number of spots on a regular basis every day.
Galileo Galilei is the one who made a major breakthrough in the history of astronomical observation. After finishing a homemade telescope in 1610, one of the celestial bodies is subject to the sun. Read more
