Arak is a type of beverage containing
ethanol, can be produced by fermentation using vegetable raw materials such as
cassava, corn, tubers, principally material containing sugar (sugar cane, sugar
palm, palm) and fibrous materials such as straw, husk, corncobs, sugar cane
baggas, cocoa pods and coffee). In addition to ethanol is classified based on
raw materials and the process is also based on water content, so there is 96%
ethanol and 99.5% ethanol (anhydrous ethanol) with a water content of 0.05%.
Furthermore, ethanol is also classified according to its use, for industry as
solvents, varnish making, and perfume. Arak has been used successfully as a
fuel known as bioethanol and is used as a reagent in making biodiesel in
processes or chemical reactions or esterification reactions as alternative
fuels.
Arak is obtained from palm and coconut
by traditional fermentation and distillation so that certain levels are
obtained. This is done routinely according to hereditary habits. To increase
levels, distillation can be done in the laboratory to increase levels of
ethanol or biethanol. Alternative fuels both bioethanol and biodiesel are
environmentally friendly because they are sourced from vegetable (plants), it
is hoped that their products can maintain the condition of the air environment
during their use. Ethanol in wine can be as a reagent with oils available in
household products or waste from food frying waste from used cooking oil from
coconut oil.
Indonesia, has the opportunity to
develop alternative fuels such as bioethanol and biodiesel, considering that
raw materials in the form of coconut oil and household cooking can be easily
obtained because Indonesia is an archipelagic country and as a major coconut
producer in the world. But the main use of coconut oil is as food, it is
necessary to know the results of the rest of the frying pan that is not
suitable for consumption means it contains many kinds of saturated fats, known
as used cooking oil. Household waste cooking oil can be processed into
alternative fuels in the form of environmentally friendly biodiesel, obtained
by the esterification process followed by the transesterification process.
Esterification reaction is the reaction between oil and ethanol contained in
the wine with a hydrochloric acid catalyst or with a double catalyst
(hydrochloric acid and toluene), while transesterification is an ester obtained
in the esterification reaction reacted again with ethanol from the wine but
using a KOH catalyst. This esterification result is known as Fatty Acid Ethyl
Ester (FAEE).
The two alternative fuels made from
ethanol that are environmentally friendly to create a clean, safe and
pollution-free environment, to create green chemistry, which starts from
households with the hope in the environment or the community can utilize this
method going forward so that the community is independent in treating home
waste each ladder on an ongoing basis.
Biodiesel (biofuel / biofuel) made from
ethanol from essential wine is developed in Indonesia, considering that there
are three types of liquid biofuel, namely (a) bioethanol, cassava based or
sugar cane which is used as a mixture of gasoline or gasohol; (b) bio-oil, wood
or lignocellulosic conversion products are converted into a liquid form through
an 'explosive pyrolysis' process; (c) biodiesel, as mixing diesel for cars and
agricultural equipment.
Bio-ethanol
and diesel levels can be analyzed by gas chromatography. Biodiesel is produced
in the form of Fatty Acid Ethyl Ester obtained from the reaction of
esterification and transesterification of coconut cooking oil with ethanol
derived from household products. Arak obtained from home industries is carried
out one, two and three times distillation to obtain higher levels similar to
laboratory standard ethanol levels.
FAEE as an environmentally friendly
transportation energy can be synthesized from household waste and cooking oil.
Analysis by GC-MS can be proven to form esters, obtained by the content of
several esters. The esters obtained depend very much on the content of used
cooking oil and bioethanol as the chosen reagent.
To use household wine and waste cooking
which is not useful as an environmentally friendly alternative energy, this
research needs to be developed in other used cooking oil that is spread in the
community to determine its content. In addition to the content of fatty acids
in oil to obtain fatty acid esters as biodiesel, further analysis is needed in
other used cooking oil which is thought to contain other compounds such as
plastic (polymer) as a material and source of poison, along with fried food.
In addition to these basic ingredients
in making biodiesel, reagents also play an important role. After using ethanol
reagents from wine (vegetable / palm ingredients)
