Abstract

Coffee is a commodity that has an important role in the national economy. Currently, coffee cultivation is threatened by climate change caused by global warming due to increased green house gas (GHG) emissions. The organic  plantation model is a farming model that is considered to increase soil and crop productivity, reduce GHG emissions, and increase carbon sequestration effectively. The study was aimed to estimate GHG emissions and carbon stocks in organic and conventional coffee plantations in Badung Regency, Bali Province and  Laboratory in Balai Penelitian Lingkungan Pertanian, Pati, Jawa Tengah Province, in July 2018. The study was conducted in smallholder coffee plantations in Badung Regency and the analysis was carried out at Laboratory of Indonesian Agricultural Environtment Research Institute. This study used a survey method, while the sampling used a purposive sampling method in organic and conventional coffee plantation. GHG emissions measurement was carried out with a close chamber method by simultaneously the carbon stocks measurement was carried out with the non-destructive method for plant biomass and destructive for understorey. The results showed that organic and conventional coffee plantations emitted GHG by 20.71 and 39.75 ton CO2e ha-1 and stored carbon stock by 227.56 and 288.31 ton CO2e  ha-1, respectively. The differences in GHG emissions and carbon stocks are partly due to differences in management system and the diversity of plant. The management system of the organic coffee plantation should be improved to support handling of the impacts of climate change in Bali Province.

Abstract

Expansion 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.
