KAJIAN POTENSI SUMBER ENERGI BIOGAS DARI KOTORAN TERNAK UNTUK BAHAN BAKAR ALTERNATIF DI KECAMATAN KALIREJO KABUPATEN LAMPUNG TENGAH
Abstract: Biogas is a source
of energy that is derived from the decomposition of organic matter by
microorganisms in the absence of oxygen (anaerobic) to produce a mixture of
several gases are methane (CH 4) and carbon dioxide (CO 2).Biogas can be made from many types of
waste material and the rest, a kind of garbage, livestock waste, agricultural
waste and others.Things to consider in the development of biogas energy source
so that the principle of availability of sustainable biogas as an alternative
fuel can be met is a local or regional potential to produce biogas.Communities
in the District Central Lampung regency Kalirejo many who maintain
livestock.Waste from livestock manure is especially very disturbing and
detrimental to health, it is encouraging to capitalize upon the waste as
feedstock for biogas production.To assess the potential of biogas energy
sources are needed data about the amount of livestock manure every day, in this
study is the dung of cows, goats and chickens.Fermentation process for the
three types of dirt inside the reactor each trial was conducted to determine
the length / time effective and energy biogas produced.From the field data
known total number of chickens are farmed as much as 176.264 , goat 12.345and
cow 4.488 tail.Manure produced by 1 chicken, 1 goats and one cow in a row that is
0.055 kg / day, 0.98 kg / day and 19.5 kg / day.While the testing laboratory,
known Biogas produced from each of 20 kg of dung that chicken manure yield of
2.04 m 3, cow dung yield of 0.56 m 3 and 0.76 m 3 cow dung.From field data and
laboratory testing can be calculated local potential in providing sustainable
biogas in District Kalirejo Kalirejo Central Lampung regency, namely the
potential of biogas from chicken manure at 988.84 m 3 / day, goat manure at
338.75m 3 / day and cow manure at 3325.61 m 3 / day.So the total potential of
biogas that can be generated is equal to 4653.2 m 3 / day.
