Description Mitigation of Green House Gases (GHGs) Emission through the implementation of intermittent irrigation on irrigated paddy field has been conducted. The aim of this study was to determine the mitigation potency by calculating the rate of growth of GHS’s emission and Global Warming Potential (GWP) on intermittent irrigation and conventional paddy field areas. GHGs’s (including CH4, CO2, and N2O) samples were collected in the irrigation area of Mrican Kanan Jombang on tertiary unit: TB 1 Ki, TB 2 Ki, TL4 Ka and conventional unit as data control. The samples were collected in three phases of rice growth which are: vegetative phase, primordia phase, and ripening fruit phase on boxes that catch GHGs. The samples were analyzed at the laboratory with chromatography gases (GC). Result from GHG’s flux indicated the values of GHG’s emission and GWP, thus the decline rate of GHG’s emission could be extracted. The study showed that the intermittent irrigation could reduce CH4 emission for about 33,18 percent and GHGs’ global warming potency for about 34,9 percent compared to conventional irrigation .
Mitigasi Emisi Gas Rumah Kaca (GRK) melalui penerapan irigasi terputus (intermittent) di lahan sawah beririgasi telah dilakukan. Tujuan penelitian ini adalah menghitung besarnya potensi mitigasi melalui perhitungan laju emisi GRK dan Global Warming Potential (GWP) pada penerapan irigasi intermittent dan konvensional. Pengambilan sampel GRK (CH4, CO2 dan N2O) dilakukan di Daerah Irigasi Mrican Kanan Jombang pada petak tersier TB 1 Ki, TB 2 Ki, TL4 Ka dan petak konvensional sebagai kontrol. Sampel diambil pada 3 fase pertumbuhan padi yaitu fase vegetatif, primordia dan pemasakan buah dalam box penangkap GRK. Sampel dianalisa di laboratorium dengan kromatografi gas (GC). Hasil pembacaaan fluks GRK ditujukan untuk mendapatkan nilai Emisi GRK dan GWP agar dapat dilihat penurunan emisi GRK pada perlakuan pemberian air secara terputus. Penelitian ini menunjukkan bahwa dengan penerapan irigasi intermittent dapat menurunkan emisi CH4 sebesar 33,18% dan potensi pemanasan global GRK sebesar 34,9% jika dibandingkan dengan penerapan irigasi konvensional (tergenang).
