Abstract
Penelitian ini bertujuan untuk mengetahui bagaimana distribusi spasial CO, menganalisis pengaruh kepadatan kendaraan bermotor, kondisi meteorologi dan penggunaan lahan terhadap konsentrasi CO di Kampus UGM. Digunakan metode moving observation technique untuk mendapatkan data primer. Hasil pengukuran yaitu: bagian utara CO pagi 20,1 ppm; siang 17,4 ppm dan sore 24,3 ppm; bagian tengah CO pagi 15,3 ppm, siang 14,7 ppm dan sore 13,1 ppm; bagian selatan CO pagi 18,4 ppm siang 18,5 ppm dan sore 28,3 ppm. Persamaan hasil regresi linier berganda yang paling sesuai dengan tidak memasukkan variabel iklim mikro adalah CO = 11,744 + 0,002 K_B. Ajusted R Square sebesar 0,276 selalu lebih kecil dari R square. Konsentrasi CO ambien di kampus UGM di bawah ambang batas baku mutu DIY yaitu 35 ppm. Kata Kunci : CO, polusi udara, kepadatan kendaraan bermotor.
