Abstract
Green open space has a function to reduce the level of carbondioxide in the air. Carbondioxide levels are generally increased due to an increase in motor vehicle exhaust gas emissions and land use changes, such as changes in open land into industrial, or agricultural land turned into housing, etc.Cibinong City in this decade had increased levels of carbondioxide caused by the developmnet of a growing city. Research purposes are (1) analyze changes of green open space and its impact on the ability to absorb carbondioxide, (2) analyze the amount of carbondioxide produced by motor vehicle exhaust gas emissions for each road segment and provide direction spatially green open space. In this decade (from 2000 to 2010), Changes of unbuilt land to built land increased from 2.268,88 Ha (35,78 %) to3.558,22 Ha (56,12 %), however, absorption of the green open spaces of the carbondioxide increases. Whereas, Carbondioxide emission strength on larger road on the Raya Bogor (City Center) 498 gr/detik which has the function of arterial roads with the task of helping regional movement. The most amount of carbondioxide emissions generated by personal vehicles, motorcycles, and ligth public trasportation, while trucks and buses do not contribute. When the carbondioxide emission strength map is overlayed with the land use map then we have the conclusion that the roads that have a high volume of vehicle movement will have a high carbondioxide levels, but not mean low air quality because it depends on the existence of protective trees as green belt. Keywords: green open spaces, carbondioxide emission levels, landuse changes

Summary
Keberhasilan pembangunan akan meningkatkan pertumbuhan ekonomi sehingga mampu meningkatkan taraf hidup masyarakat luas. Mengetahui perubahan lahan dan polanya, serta volulme lalu lintas akan membantu melihat fungsi ekologis ruang terbuka hijau, khususnya parameter karbondioksida, di suatu kota atau ruas jalan kota. Hal ini terjadi karena penggunaan lahan Kota Cibinong terdapat daerah industri, kegiatan transportasi yang tinggi dan pusat permukiman, sehingga kualitas air hujan memiliki konsentrasi SO42-, NO3-, Karbondioksida dan NH3 yang tinggi. Berdasarkan uraian di atas maka penelitian fungsi ekologis ruang terbuka hijau di Kota Cibinong sangat penting dilakukan sehingga tujuan penelitian ini adalah: 1) Menganalisis perubahan ruang terbuka hijau (lahan non terbangun) sejak tahun 2000 sampai dengan tahun 2010 dan pengaruhnya terhadap kemampuan daya serap karbondioksida, 2) Menganalisis besarnya kadar Karbondioksida setiap waktu yang dihasilkannya di setiap ruas jalan yang diakibatkan oleh kendaraan bermotor dan kaitannya dengan penggunaan lahan
