High-school student from Bantul Find Alternative Electric Leaves Sambiloto

Encouraged by the energy crisis was slowly increasing its impact, three female students at SMU 1 Bantul, Yogyakarta trying to find a simple solution for problems of race tersebut.Melalui tuils work of scientific level of SMA / SMK / MA as the Java-Bali 2011 which was held by SMAN 2 UPTD Nganjuk, East Java became a means of doing research and discovery.

EMR Kemeterian third release of this high school student doing research for 4 months to find alternative energy sources. They are looking for an alternative energy source from something that is commonly found all around us. "Their efforts were not in vain. Their choice eventually fell on the leaves of plants called latin Andrographis paniculata or in Indonesian society known as Sambiloto." Thus expressed Ministry of Energy and Mineral Resources said on its website.

Rima Melati, Sri Astutiningsih and Muafiqoh Dwiarini not alone in doing his research. They were accompanied by Head of SMU 1 Bantul, Drs. Isdarmoko, M. Pd and Reni Shintasari, students Fisipol UGM.Dijelaskan, the process of making an alternative source of electrical energy is done with the principle of the battery. By Rima Melati, one of the team, the research is quite complicated.

However, three months ago, then they find Sambiloto leaf extract has an electrolytic nature. "As many as 1 kilogram of leaves Sambiloto pulverized and blended to get the extract which is then mixed with 2.5 liters of pure water or aquades. The result is three liters of liquid from the leaves of battery Sambiloto , "obviously they are in the research.

In experiments performed during the race on 3 April 2011 and then, the battery liquid from the leaf extract Sambiloto consisting of 6 cells and produces a voltage 2.5 Volt. Stress is able to turn on the light electric power 0.72 Watt. "Each battery cell filled with 500 milliliters and placed electrodes made of zinc and copper plates."

According to them, Sambiloto leaf extract is actually able to turn on the lamp 5 watts for one full month. It's just that it takes 16 liters of extract of leaves tersebut.Sama like batteries in general, liquid extract of the leaves Sambiloto battery needs maintenance if it is experiencing performance degradation.

Sambiloto leaves according to their battery is also necessary to add more extract, when a decline in performance.
