The carbon footprint from ruminant livestock in the breeding-green farm in Jember

Abstract

Abstract Livestock, especially ruminants, potentially emit nitrous oxide (N2O) and methane (CH4) gas through enteric fermentation activities from the eructation process and dung management (DM) activities. This study aims to determine the emissions gas of CH4 and N2O from livestock ruminants in the livestock breeding-green in Jember. The gas emission calculation method follows an international agreement initiated by the Intergovernmental Panel on Climate Change (IPCC) 2006, with Layer-2 for CH4 and Layer-1 for N2O. The results showed that the amount of CH4 emission from enteric fermentation was 103,321 tons CO2-eq per year, higher than DM, which is 4,510 tons CO2-eq /year. The amount of indirect N2O emissions from DM is 0.0763 tons CO2-eq /year, higher than direct N2O emissions from DM, which is 0.0527 tons CO2-eq /year.
