Jakarta as one of the biggest city in Indonesia, it own more than 6.506.244 units of motor vehicles. The combustion of fossil fuels in motor vehicles can cause air pollution. Station is represented as one of heavy pollution location. The observation has be done by abservate the amount of vehicles, stomatal characteristic, and weight of dust on Angsana leaves, which growth around Lebak Bulus station. As the result, there is relation between weight of dust on leaf and stomatal characteristic, with r value = 1. The level weighat of dust on leaf has effect to stomata conditions, such as surface of stomata become smaller and shape of stomata become irregular, but amount and size of stomata didnâ€™t influenced. In some case, leaf can be identifid by visible symptoms of injury such as chlorotic at the leaf veins, which caused by SO2 or black or brown flecks at the leaf veins, which caused by NOx.

Lignite coal was found abundant in Indonesia, but usage for this type of coal was still relatively low. Economic value of coal increases when it is solubilized. Biosolubilization of coal by utilize of microbes produces compounds equivalent to petroleum. In this research, effect of urea on lignite biosolubilization by Trichoderma sp. was examined. Method of this research consisted of spore inoculum preparation, biosolubilization lignite coal with a variety of treatment that consists of treatment A (MSS + sucroseÂ 1% + coal 5% + urea), and treatment B (MSS + sucroseÂ 1% + coal 5%). Results showed that the addition of urea supported lignit coal biosolubilization by Trichoderma sp. based on increase in medium pH, concentration of phenolic and conjugated aromatic compounds, and activity of extracellular enzyme. In addition, result of product characterization using GCMS revealed compounds equivalent to 13,60%, 26,20% and 90,8% respectively for gasoline, kerosene and diesel components. Those confirmed that urea can be used as an alternative nitrogen source to support Trichoderma sp. in lignit biosolubilization producing petroleum compounds.

Methane is one of the greenhouse gases produced by ruminants. One way to reduce methane is by feeding development strategies. Concentrates or forage are two possible forms of animal feed. Forage can be replaced with citronella (Cymbopogon nardus L.) residue, which has not been fully consumed as feed. The purpose of the study was to decide the production of methane gas that has residual citronella to concentrate in buffalo rumen fluid in vitro, for 48 hours. The treatments in this research were 0.4 g citronella residue (A); 0.4 g citronella residue + 0.01 g concentrate (B); 0.4 g citronella residue + 0.02 g concentrate (C); 0.01 g concentrate (D); and 0.02 g concentrate (E). For the 48-hour measurements, the highest methane gas production was treatment 98.2% (D); followed by 92.06% (E); 17.71% (C); 15.33% (A); and 13.54% (B). It can be concluded that methane gas can be reduced by residue citronella. This shows that citronella residue can lower methane gas. The study's findings are anticipated to be among the references for using agricultural product residues, particularly citronella as animal feed to reduce the methane produced by the livestock industry
