Hydrocarbon Refrigerant Refrigerant = The Future

By Abdallah Nur Siddiq-destruction of the ozone layer and the effects of global warming, one of which was caused by the use of materials containing chlorine (Cl). The source of the element chlorine could be a refrigerant/refrigerant from the CFC (Chloro Fluoro Carbon). But in everyday life, the application of refrigerant is very much, which is worn on the refrigerators, Air conditioners, and almost all the other cooling machine. Where… Read More »Hydrocarbon Refrigerant Refrigerant = The Future

Corrosion in Geothermal Systems

By Abdallah Nur Siddiq-corrosion is the definition of material damage by chemical or electrochemical action of the surrounding environment. Effect of corrosion on the metal surface of the geothermal fluid depending on the chemical composition of the fluid and metal materials. Geothermal fluid has a wide range of composition, of the fluid with high acidity levels that contain sulfur and halogen acids are actively mengkorosi many alloys up to high… Read More »Corrosion in Geothermal Systems

The main problems in Geothermal-System Scaling

By Abdallah Nur Siddiq-definition of the scale is the deposition of solids on the surface of the metal, stone, or other material. Geothermal systems, the scale of the geothermal fluid berfase liquid (water). There are 3 classes of minerals in geothermal fluid that can cause the onset of scaling, i.e.: Silica and silicates Carbonate of calcium and iron Sulfides of iron and heavy metals Water is a universal solvent so… Read More »The main problems in Geothermal-System Scaling

The potential of Geothermal Energy and independence Indonesia

The development of renewable energy geothermal/geothermal in Indonesia for the purpose of electricity for 25 years ago are still very small, amounting to about 4% of total national energy. But Indonesia has a geothermal energy reserves are very large reach 27,140 MW or about 40% of the world's geothermal reserves (Eddy, 2011). If Indonesia, Arabic is likened to Geothermal. Geothermal is very potential for continued development, because it's free, sustainable… Read More »The potential of Geothermal Energy and independence Indonesia

Garbage as a solution to Global warming and the energy crisis

By Abdul Halim and Nur Abdillah Siddiq-global warming resulting from the use of fossil fuels became the topic of a very booming pyang in this decade. The impact of global warming is one of them is a significant climate changes that threaten the life of living beings. One of the widely used fuel is coal. The year 2009, the United Nations invited heads of State from dozens of countries agreeing… Read More »Garbage as a solution to Global warming and the energy crisis

Dye Sensitized Solar Cell and its discoverer (m. Gratzel)

Have ever been thought of yet when Indonesia layout where the equator is a grace and a gift from God which is priceless? Yes, Indonesia is very lucky to pass the line of the equator, it means Indonesia traversed by the Sun in each day, although sometimes clouded so long rainy season.  The territory of Indonesia will always in sunlight for 10 up to 12 hours in a day (Djoko Adi… Read More »Dye Sensitized Solar Cell and its discoverer (m.

The origin of "mass" according to the PHYSICS of glasses, why is there a particle that Has Mass (e.g. an electron) and why some are Not (e.g. photons)

= Mass of the giver of the particle the Higgs particle By Abdallah Nur Siddiq-according to physics, the Higgs particle that cause mass effects. The Higgs particle is taken from the name of the person who first formulate, Peter w. Higgs. In simple terms, the Higgs particle contained in an object mass (more precisely is the Higgs particle interacting with something so something that has mass, as you will know… Read More »The origin of "mass" according to the PHYSICS of glasses, why is there a particle that Has Mass (e.g. an electron) and why some are Not (e.g. photons)
