Wildani Mahmudah, Shella Azen Noviasari, Dhany Damayanti, Gigih Prihantono.


his research aims to estimate the emission of CH4 gas from the utilization of biogas technology as a source of alternative fuels and biogas has an influence on the economic condition of the society of Ploso Ngamban Village, Kendal, Ngawi East Java who has been utilizing biogas.
