| Abstrak (Bhs. Indonesia) | Pertanian padi sawah,khususnya sawah teririgasi merupakan sebagai salah satu sumber emisi Gas Rumah Kaca (GRK) yang menyebabkan terjadinya pemanasan global (global warming). Tujuan penelitian ini antara lain (1) Mengetahui dinamika Gas Rumah Kaca (CH4, CO2 dan N2O) pada penanaman padi menggunakan metode SRI (System of Rice Intensification) dan Konvensional dengan perlakuan penambahan arang selama 1 masa tanam padi. (2) Mengetahui faktor-faktor yang mempengaruhi emisi Gas Rumah Kaca pada penanaman padi dengan metode SRI (System of Rice Intensification) dan Konvensional. Penelitian dilaksanakan pada bulan April 2013 sampai bulan Juli 2013 di Desa Banjarsari wetan Kecamatan Sumbang Kabupaten Banyumas dan sampel gas dianalisis di Laboratorium Balai Penelitian Lingkungan Pertanian, Badan Penelitian dan Pengembangan Pertanian Departemen Pertanian di Kota Pati, Jawa Tengah. Variabel yang diamati dalam penelitian ini antara lain, emisi gas rumah kaca (CH4, CO2 dan N2O) , dan Evapotranspirasi selama pertumbuhan tanaman. Penelitian yang dilakukan menggunakan 2 metode yaitu metode SRI (System of Rice Intensification) dan Konvensional, masing-masing menggunakan perlakuan penambahan arang, dengan dosis arang 5 ton/ha, dosis arang 10 ton/ha dan dosis arang 20 ton/ha. Hasil penelitian padi selama satu musim tanam atau selama masa penanam dengan menggunakan metode SRI (System of Rice Intensification) dan Konvensional dengan perlakuan penambahan arang menunjukkan bahwa total emisi Gas CH4 tertinggi 415,24 ppm/hari pada metode Konvensional perlakuan penambahan arang 20 ton/ha, untuk emisi gas CO2 tertinggi 2336,48 ppm/hari pada metode SRI perlakuan penambahan arang 20 ton/ha sedangkan untuk emisi gas N2O tertinggi 2056,36 ppm/hari pada metode SRI perlakuan penambahan arang 5 ton/ha. Faktor-faktor yang mempengaruhi emisi Gas Rumah Kaca pada penanaman padi dengan metode SRI (System of Rice Intensification) dan Konvensional dengan perlakuan penambahan arang dipengaruhi oleh lingkungan, pH, suhu permukaan, kadar air tanah, evapotranspirasi dan penambahan arang. |

| Abtrak (Bhs. Inggris) | Rice farming, especially the irrigated, is one of the sources of Greenhouse Gasses Emission causing global warming. This research aimed at (1) examining the greenhouse gas dynamics (CH4, CO2 and N2O) during rice planting processes that applied SRI (System of Rice Intensification) and conventional methods implementing charcoal addition treatment, (2) examining the factors affecting the greenhouse emission during the rice planting processes that applied the SRI (System of Rice Intensification) and conventional methods. This research was conducted from April 2013 to July 2013 at East Banjarsari village, Sumbang sub-district, Banyumas regency. The samples of the gasses were analyzed at the Laboratory of Farm and Environment research office, the part of Indonesian Department of Agriculturet at Pati, Central Java. The variables observed in this research were: the greenhouse gas emission (CH4, CO2 dan N2O), and crop evapotranspirasi during one crop season. The research was carried out by implementing two particular methods: SRI (System of Rice Intensification) and conventional methods. In each of the method implementation, the charcoal addition treatment was conducted, and the doses were 5 ton/ha, 10 ton/ha, and 20 ton/ha. The results of the observation during the cultivating season show that the highest total of CH4 gas emission was 415.24 ppm/day occurred when the Konvensional method was applied and 20 ton/ha of charcoal were added, the highest total of CO2 gas emission was 2336.48 ppm/day occurred when the SRI method was applied and 20 ton/ha of charcoal were added, and the highest total of N2O gas emission was 2056.36 ppm/day occurred when the SRI method was applied and 5 ton/ha of charcoal were added. Moreover, it was found that the factors affecting the greenhouse gas emission during the planting processes when the SRI (System of Rice Intensification) and conventional methods were implemented and the charcoal treatment were conducted were the environment, the pH, the surface temperature, the level of ground water, the evapotranspiration, and the addition of charcoal. |
