Aceh has a large potential of biogas energy development. According to Central Bureau of Statistic's data 2013, the total population of cattle in Aceh Province is 701,284. Since 2012, YKU Foundation has been developing a biogas energy program made of cow and designing a reactor which is simple and affordable by the community. It is constructed from polyethylene (PE) plastic 0.2 mm, with unit price IDR 10,000,000.- (around USD 909.09, with USD 1 = IDR 11,000). Animal waste of 100.000 cows would potentially yield biogas energy as much as 36.000 m3 (27 million litres of kerosene) / year. If CO2 emission factor = 2.5359, then CO2 emission out of kerosene consumption is approximately 68.469.300 kg CO2/year. From economical perspective, the saving of kerosene at amount of 2,250 kilo litres is equal to IDR 22.5 billion (USD 1.9 million) per month or IDR 270 billion (USD 23.48 million) per year. During 2014, YKU is being an implementing partner of USAID for Indonesia Clean Energy Development (ICED) Program, with the objective to increase people's energy independence and to preserve the environment, to support the improvement of the local economy, and ultimately to reduce the carbon emission as much as 281,000 kg CO2 per year. It is eventually expected that these activities would contributes to Indonesia emission reduction efforts, and to widespread use of biogas energy specifically in Aceh, and throughout Indonesia in general.
