Penyumbang terbesar emisi gas karbon monoksida diperkotaan adalah kepadatan lalulintas yang tinggi akibat peningkataan pemakaian kendaraan bermotor. Iklim mikro juga memiliki peranan dalam peningkatan konsentrasi karbon monoksida. Penelitian ini dilakukan untuk mengetahui pengaruh kepadatan lalulintas dan variabel-variabel iklim mikro (suhu, kelembaban, dan angin) terhadap konsentrasi karbon monoksida di daerah Kartasura. Lokasi pengambilan sampel di pilih di lokasi yang memiliki perbedaan morfologi jalan. Penelitian ini menggunakan metode observasi dengan 3 lokasi pengamatan. Masing-masing titik di ukur selama 17 jam dengan mengambil data kepadatan lalulintas, konsentrasi karbon monoksida, suhu, kelembapan, dan kecepatan angin. Analisis deskriptif digunakan untuk menggambarkan kondisi daerah penelitian, sedangkan analisis statistik korelasi dan regresi untuk mengetahui besarnya hubungan variabel-variabel yang terlibat.

The high traffic density, caused by the increasing usage of motorizes vehicle, give the biggest carbon monoxide emission contribution in the urban area. The micro climate also give role in the carbon monoxide concentration improvement. The study was aimed to identify the effect of traffic density and the micro climate variables (temperature, humidity, and wind) towards the carbon monoxide concentration in Kartasura. The sample was taken from the location that had road morphology differences. The study applied the observation method that had three observation points. Each observation point was measured for 17 hours by taking the data on traffic density, carbon monoxide concentration, temperature and wind speed. Descriptive analysis was used to describe the condition of the study area. Whereas, statistic analysis of correlation and regression was used to identify the amount of the relations among the variables involved. In Jalan Jendral Sudirman, the traffic density and the carbon monoxide were strongly correlated (0,561) with the regression CO Jalan Jendral Sudirman 1,234+0,001 smp. Meanwhile, the temperature was strongly correlated (0,544), the humidity was strongly correlated (-0,582), and the wind was adequately correlated (-0,304), the regression equation was CO Jalan Jendral Sudirman 35,181+0,001smp-0,596 temperature-0,271 humidity-0,006 wind.
