Abstract: | Production of Jatropha as a biofuel can be increased by fertilization. Subtitution chemical fertilizer into organic fertilizer have to consider the methane (CH4) emissions from soil that fertilizer applied. In this study the rate of methane (CH4) emission from jatropha cake compost (-0.99 CH4/m2/hour) and peanuts intercrops (- 0.62 CH4/m2/hour) is lower than urea fertilizer (- 0.04 CH4/m2/hour). Carbon sequestration is a reference to see the potential of the plant to reduce the CO2 in the atmosphere. Application of urea fertlizer showed carbon uptake (13.62 tonnes C/ha/year) higher than between fertilizer application (12.83 ton C/ha/year) and jatropha cake compost (11.09 tonnes C/ha/year). The productivity of jatropha from the jatropha cake compost (152 kg/ha/year) and intercrops (147.1 kg/ha/year) application was higher than urea fertilizer (147 kg/ha /year). |
