dc.descriptionExpansion of sugarcane areal to support enhancement production and fulfilment target of self-sufficiency for national sugar should be conducted to see environment impact, particularly related to greenhouse gases emission. The objective of this study was to figure out N2O emission from conventional sugarcane plantation by farmer in rainfed area. The observation of N2O gas was carried out in sugarcane plantation in Sidomukti Village, Jaken District, Pati, Central Java. Sampling of N2O gas was conducted by close chamber method. The study showed that maximum fluxes of sugarcane plantation before and after fertilizer application are 4.011 and 223 µg N2O m-2 day-1. Meanwhile, after fertilizer application the maximum and minimum fluxes of N2O are 6.408 and 25 µg N2O m -2 day-1. N2O emission from sugarcane plantation recorded in rainfed area as 4.21 ± 2.53 kg N2O ha-1 year-1 with potential of global warming number as 1.31 ton CO2-e per hectar per year.Emisi N2O dari Pertanaman Tebu di Lahan Tadah HujanPerluasan areal tanam tebu untuk mendukung peningkatan produksi dan pemenuhan target swasembada gula nasional sudah dianggap perlu untuk melihat dampak lingkungan khususnya mengenai evaluasi emisi gas rumah kaca dari pertanaman tebu. Tujuan dari penelitian ini adalah untuk mengetahui emisi gas N2O dari sistem pertanaman tebu secara konvensional petani di lahan tadah hujan. Pengamatan gas N2O dilakukan pada lahan perkebunan tebu di desa Sidomukti Kecamatan Jaken Kabupaten Pati Provinsi Jawa Tengah. Pengambilan sampel N2O menggunakan metode sungkup tertutup. Hasil penelitian menunjukkan bahwa fluks maksimum pada pertanaman tebu sebelum pemupukan sebesar 4,011 µg N2O m -2 hari-1 dan fluks minimum sebesar 223 µg N2O m -2 hari-1, sedangkan fluks maksimum setelah pemupukan sebesar 6,408 µg N2O m -2 hari-1 dan fluks minimum sebesar 25 µg N2O m -2 hari-1. Emisi N2O pertanaman tebu sebesar 4.21 ± 2.53 kg N2O ha-1tahun-1 dengan nilai potensi pemanasan global sebesar 1.31 ton CO2-e per hektar per tahun.en-US
