Alternative energy is the energy source produced from ingredients that have not been widely
utilized. Currently, research on
alternative energy over to the alternative
energy use and
natural ingredients sourced from nature. According Sutikno
(2008) of electrolytes in batteries are acidic, so
the fruit can become acidic electrolyte. Innocencio
Krishna Primary (2007)
adds, that in addition to oranges and apples,
other fruits, can also generate electricity.
Experiments Wasis Sucipto, S. Pd (2007) proved that a
banana peel and orange can be used as a source
of direct electric current.
This raises issues such as: How is the
performance (voltage and resistance) dry batteries which use raw materials
from banana skins?
and How does a
banana skin type of battery performance?
Results showed that
the average voltage produced by the dry battery with electrolyte banana skin is
1.24 volts. And resilience in the average wall clock for 5 days 6 hours (135 hours).
Construction of a banana skin dry batteries with regular batteries. The
difference is in the electrolyte. Banana peel contains some minerals that can
serve as an electrolyte. Minerals in the greatest number is potassium or potassium
(K +). Banana skins also contain salts that contain sodium chloride (Cl-) in
small amounts. The reaction between potassium or potassium and sodium salts can
form potassium chloride or KCl. According to Drs. Asep Jamal (2008) KCl is a strong
electrolyte capable of ionized and conduct electricity.
Bananas also contain Magnesium and Zinc. Magnesium (Mg) can react with the dichloride and a strong electrolyte. Number of Magnesium is 15% of the total amount of bananas. Bananas also contain Zinc (Zn) which is the positive electrode. amount of zinc content in bananas only reach 2%. So that the minerals that were most responsible conduct electricity is potassium or potassium, which react with the sodium salt. Possible salts of magnesium and zinc also played a part in delivering and storing electric current direction.

The results also
showed, control battery can last more than 7 days while the battery is just a
banana skin for less than 6 days. This is due to control battery has a compound
that serves as a depolarization. The compound used is mangandioksida. Although bananas
also contain manganese, but the number was only 0.6 mg per 100 g. Besides, each
reaction in a battery having a polarization process due to hydrogen gas that
escapes. Bananas and banana peels primarily containing more than 60% water
content (H20), which can be detached in the event of a chemical reaction. So
the possibility of polarization is very large. This is resulting in differences
in resistance between the battery and battery control banana skin large enough.
While these three types of bananas, the banana milk that has the highest resistance.
However, due to the difference in resistance between the banana milk banana and
other types of less than 24 hours, it can be argued that the resistance between
the three types of bananas does not provide significant differences.a
Other
complementary data, the net weight of the battery data show that the average banana
skin used was 3.3 grams per battery. While the banana skin intact on average 27
grams per one fruit. So that one could be a banana peel about 8 batteries. This
is another advantage of the dry battery of a banana skin.
Conclusions from the study above is a dry battery using a banana peel raw material has an average voltage of 1.2 V and the resistance of an average of 5 days 7 hours and Among the three types of bananas does not provide the difference in performance (voltage and resistance) are significant.
