Inventarisasi Emisi Gas Rumah Kaca (CH4 dan N2O) Dari Sektor Peternakan Sapi Dengan Metode Tier-1 IPCC di Kabupaten Muaro Jambi

Abstract

Gas rumah kaca (GRK) dalam bentuk CH4 dan N2O memberikan kontribusi terhadap pemanasan global. Sektor pertanian menyumbang 10-12% dari total GRK antropogenik dari gas CH4 dan N2O. Sedangkan sektor peternakan menyumbang sekitar 18-51% GRK antropogenik. Penelitian bertujuan untuk menganalisis beban emisi gas CH4 dan N2O bersumber dari Peternakan terhadap GRK Di Kabupaten Muara Jambi yang diestimasi dengan menggunakan metode Tier-1 IPCC. Pada metode ini data yang diperlukan adalah populasi ternak dalam satu tahun 2018 dan nilai faktor emisi (FE) setiap gas GRK menurut buku panduan IPCC (2006). Data populasi ternak sapi diambil dari buku statistic peternakan, sedangkan nilai FE diambil dari buku IPCC (2006). Hasil penelitian menunjukkan beban emisi gas CH4 dari fermentasi enterik 1,1227 Gg CH4/tahun, Emisi CH4 dari Pengelolaan kotoran 0,0239 Gg CH4/tahun, emisi N2O langsung dari pengelolaan kotoran 465,85 Kg N2O/tahun dan emisi N2O tidak langsung dari pengelolaan kotoran ternak 69,88 Kg N2O/tahun. Sektor peternakan telah berkontribusi terhadap pemanasan global yang bersumber dari gas CH4 dan NO2 baik dari fermentasi enterik maupun dari pengolaan kotoran ternak sapi.

Inventories of Methane Emission for Enteric and Decomposition Gasses from Cattle Manure and Its Mitigation Strategies

“…Therefore, it is crucial for Jambi Province to develop effective strategies to manage CH4 emissions, especially from dairy cattle, to mitigate the impact on the environment. Such strategies should aim to reduce the amount of CH4 produced by dairy cattle while increasing their productivity and overall health (Syarifuddin et al, 2019). This condition will be give negative impact on ozone.…”

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

“…The emissions in [12] with TIU for Livestock Breeding-Green Forage Jember is the same as the emissions of 5 mature dairy cows in TIU Jember, which is 10.800 kilotons of CO2-eq /year or 2.150 kilotons of CO2-eq /year /head. The previous research [4] stated that the emission of CH4 in livestock from EnF is influenced by livestock type and population.…”

“…The livestock subsector was based on two main activities, namely enteric fermentation (EnF) and dung management (DM), and potentially emitted gases of CH4 and N2O. The gas emission of CH4 and N2O was based on [4], which showed that CH4 emissions amounted to 1.1466 Gg per year, and N2O emissions amounted to 535.73 kg per year. Methane gas from enteric fermentation occurs during digestion when microorganisms in livestock, particularly ruminants, break down carbohydrates [5].…”

Estimation of greenhouse gases in rice fields and plantations in Teluk Bintuni Regency, West Papua

“…Data were taken from 15 farmer groups from 15 districts and 6 households of rice farmers assisted by Tangguh LNG CSR in Teluk Bintuni Regency. The calculation method uses IPCC 2006 Tier 2[53,54]. The correction factor used in calculating the Bintuni GHG is adjusted based on land area, soil type, type of fertilizer, type of irrigation used.The calculated GHG emissions from the agricultural and plantation sectors are from rice planting activities, fertilizer use, and soil management.…”
