Is Dr. Fatimah, Make Clay and Skin Mangosteen for Capturing solar cells

Environmentally Friendly and Cheap, Can Help The Backpacker

Efforts to find a cheap alternative energy and environmentally friendly continue to be the experts. Is Dr. Fatimah, UII lecturer Jogjakarta, utilizing clay and skin mangosteen fruit as a catcher and storage of solar cells. Like what?

NATURE Is Fatimah as a woman who had two sons and a daughter do not release their will to develop his love of researching. Passionate lecturer researching birth March 19, 1975 is getting into every time you finish discussing with the students in Jogjakarta UII.
New research is trying to create a tool capable of storing solar cells. In the early initiated, he had to limit the tools that he created must be environmentally friendly as well as inexpensive. "As busy dealt, now more popular the search for alternative renewable energy or sustainable," he said in Jakarta last Friday (21/10).
Thanks to this research, won the contest Is a special study of young women are entitled L'Oreal-UNESCO for Women in Science. As one of five winners, Is entitled to a research scholarship of Rp 70 million. He target, the creation of this new tool be completed no later than one year.
When designing the study, women who earned a doctorate degree from Gadjah Mada University was thought that the sun is a blessing that is important. Sunlight categories including sustainable energy sources (ongoing).
According to him, in a day, on average the sun shines in Indonesia for about ten hours. Every second the sun's rays is, Is said, can be used as a source of electrical energy into renewable category. He believes that the energy released when the sun is just out of Judgement. "So, it should be fully utilized," he said.
During this time, according to Is, the technology used to capture solar cells are relatively expensive and less environmentally friendly. In the market, that equipment can be sold at a price of up to tens of millions of dollars. In addition, these materials are less environmentally friendly manufacturer. Starting material silicon, plastic, iron, and aluminum.
Lecturers who had received his education a few extra times in Australia and Singapore were explained, as the researchers themselves must continue to explore new things. Primarily to deal with problems as well as catcher materials storage solar power less expensive environmentally friendly and tend them.
Is was then racked his brain. He also repeatedly back and forth from the laboratory of Faculty of Mathematics and Natural Sciences UII Jogjakarta to the campus library to find reference materials catcher solar cells that are environmentally friendly. Some time later, he decided to use clay (clay) and the skin of the mangosteen fruit (Garcinia Magostana L.) as well as storage media catcher solar cells.
For business looking for clay, Is not afraid to admit out of stock. Especially natural montmorillonite clay which he claims is quite superior in this project. He called the potential of this type of loam in Indonesia reached 380 million tons. Most numerous in Boyolali, Central Java and Tasikmalaya, West Java. Typically, this type of clay used for ceramics raw materials.
Predicate-winning lecturer was telling example of UII 2004, before being used for fishing equipment as well as storage of solar cells, clay must be modified. Among these, combined with titanium dioxide material. "Basically, the capture of solar cells that titanium dioxide," he said.
So what was the role of clay? Is said, the clay acts as a means of extending the reach of capture and storage of solar cells. He then made a simple analogy. Namely, together with receiving water at the same waterfall, people who use the bucket will get more water than people who use glasses.
"Something like that. The wider tangkapnya power, solar cells stored more and more," said the woman who won the award three times the lecturer terproduktif write a scientific paper that UII.
After peeling the role of clay, Is explained mangosteen peel. For availability of mangosteen peel, Is not worried. As a tropical country, Indonesia is well suited for growing fruit with a sweet taste sour. He said, before use, mangosteen skin needs to be taken is extracted pigment color.
Mangosteen skin pigment that has been extracted is going to strengthen the role of clay and titanium dioxide in capturing and storing solar cells. Work systems mangosteen peel extract to absorb solar cells with exactly the process of photosynthesis. Sunlight is absorbed to help cook their own food crops.
Molecular function of skin color on the mangosteen extract is believed to stimulate the absorption of solar cells in the slab of clay and expedite the flow of storage based on titanium dioxide. "Utilizing the clays course has helped arrest the solar cells. Moreover, if the up grade again with the help of mangosteen peel extract. Surely a more optimal outcome," said Is.
He admitted that in this country as well as efforts to create tentacle storage of solar cells that are environmentally friendly and cheaper still less desirable. Because, first stamped complicated and difficult to obtain material raw material. But, according to Is, the difficulty would be comparable to the impact of its use on the health of Earth's survival.
Is confident this study will generate sufficient appropriate equipment. He compared with similar efforts undertaken a number of countries in Europe. Many countries in Europe that has been developing environmentally friendly technology in capturing and storing solar cell which is then converted into electrical energy.
Looking ahead, Is going to develop the results of this research for various purposes. Among other things, a kind of tool charge mobile phones (HP) that can be taken anywhere. "People already do not bother looking for plugs or batteries to buy," he said.
By designing a charger (HP) portable made from clay and mangosteen peel extract into fist-sized adult, a tool that can be placed in backpacks.
"Sure helps lovers travel or backpacker community," he said. After a day of absorbing solar cells, HP portable charger can be used in the forest even if that does not get stun from electricity supply.
For the calculation of cost of production, Is not measure it in detail. But, if the tool made from clay and skin extracts of the mangosteen fruit that can be mass produced, their cost of production can be suppressed and to reach hundreds of thousands of dollars only.
Now, Is still the focus of the research stage to create the tools. If it is really effective is capable of capturing and storing solar cells, and then discuss the cost of production that's right for the pockets of the backpacker. (C2/nw)
