Abstract

Carbon emissions is one of the activities of agroecosystem impacts of oil palm on peat land as a result of the making drainage and plant growth. This research was conducted in the area of oil palm agroecosystem on peat land landscape, Ogan Komering Ilir District, South Sumatra with the aim of estimating reserves and carbon emissions on the land. Contribution of carbon emissions on the land with plant age 5, 3 and 2 years without drainage channels are respectively 12.027; 11.262 and 9.783 tons CO2/year, as well as plants age of 5 years with the drainage channel is 14.723 tons of CO2/year. Contribution of carbon emissions from the making drainage channel reaches 2,696 tons of CO2/ha/year and greater than the contribution of carbon emissions from the aging plant palm oil annually, amounting to 0.383 to 1.479 tons of CO2/ha/year.

Abstract

ABSTRAK. Peranan gambut terhadap lahan degradasi menjadi sangat penting dan bernilai dalam hal cadangan karbon karena berdampak terhadap hilangnya vegetasi akibat penggundulan dan kebakaran hutan. Penelitian ini dilaksanakan pada lahan gambut pada agrosistem kelapa sawit di Kabupaten Ogan Komering Ilir, Sumatera Selatan. Tujuan penelitian ini untuk menduga cadangan karbon gambut. Hasil penelitian menunjukkan bahwa kedalaman gambut berkisar antara 200 – 850 cm, bulk density antara 0,211 – 0,347 g cm-3 dan kandungan organik C sekitar 56,30 - 58,31%. Prediksi cadangan karbon adalah sebesar 1,675.361 - 9.055,922 ton C ha-1. The Prediction of Peatland Carbon Stocks in Oil Palm AgroecosystemsABSTRACT. The role of peat on degraded land becomes extremely important and valuable, for being the last carbon stocks because of the loss of vegetation due to deforestation and forest fires. This research was conducted in peatlands that have been used for oil palm agro-ecosystem, Ogan Komering Ilir District,  South Sumatra. The purpose of the study was to estimate carbon stocks in peatlands. The results showed that the peat depth ranged from 200 to 850 cm, the bulk density between 0.211 to 0.347 g cm-3 and the organic C content of approximately 56.30 -58.31%. The prediction of carbon stock ranged from 1.675,361 ton C ha-1 to 9.055,922 ton C ha-1.

Abstract

The purpose of this study is to analyze nitro oxide emissions as a result of adding urea and zeolite to rice plants (Oryza sativa L.) on peatlands. The treatments used were 2 factors, namely factor 1 using a dose of urea fertilizer from three levels of treatment N1 : 125 kg/ha; N2 : 250 kg/ha; N3 : 375 kg/ha and factor 2, the dose of zeolite consists of three levels of treatment Z1 : 125 kg/ha; Z2 : 250 kg/ha; Z3 : 375 kg/ha. Each combination was repeated as many as 5 phases (phase 1 = 15 DDP, phase 2 = 35 DDP, phase 3 = 55 DDP, phase 4 = 65 DDP and phase = 90 DDP) so the number of units treatment 3 x 3 x 5 = 45 pots. Data analysis used linear regression test. The results showed the administration of a combination of urea doses and zeolite in rice plantations had not significant effect on nitrous oxide emissions produced at each observation. In this study, the highest nitrous oxide emissions were obtained in phases 1 and 2. From the results of the F test is Ho rejected. With this it is proven that the urea dose partially has not significant effect on nitro oxide emissions. The dose of zeolite (X2) is H0 is rejected, thus showing that zeolite has not significant effect on the availability of nitrous oxide emissions.Keywords: Urea, Zeolite, Nitro oxide emissions peatlands
