"Sebagai salah satu komponen sistem transportasi, terminal merupakan titik simpul dalam jaringan transportasi. Terminal merupakan tempat dimana penumpang masuk dan meninggalkan lokasi serta mempunyai peran penting untuk pengendalian dan pengaturan sistem pelayanan angkutan umum. Permasalahan yang terjadi di terminal adalah terjadinya kondisi antrean bus yang sedang menunggu penumpang pada lajur bus terminal. Dampak yang diakibatkan oleh kondisi antrean tersebut adalah meningkatnya emisi gas buang kendaraan bermotor. Salah satu emisi gas buang kendaraan bermotor yang berbahaya dan sulit dikendalikan adalah polutan NOx yang terdiri dari polutan NO dan polutan NO2. Oleh karena itu, perlu dilakukan penelitian terhadap konsentrasi NOx pada udara ambien di sekitar lajur bus terminal. Metode yang digunakan untuk pengukuran konsentrasi NOx adalah metode Griess Slatzman sesuai dengan SNI 19-7119.2-2005. Hasil penelitian menunjukkan jenis kendaraan berbahan bakar gas memiliki kontribusi terkecil dalam mempengaruhi besarnya nilai konsentrasi NOx yang terukur di lajur bus terminal blok-m.

As one component of the transportation system, terminal represents a nodal point in transportation network. Terminal is a place where passengers enter and leave the site as well as having an important role for the control and regulation of public transport service system. The problems that occur in the terminal is the condition of the bus queue for waiting the passengers at the bus lanes. Impact caused by the condition of the queue is increasing exhaust emissions of motor vehicles. One of the exhaust emissions of motor vehicles which is dangerous and difficult to control is NOx pollutants, consisting of NO and NO2. Therefore, it is necessary to study the NOx concentration in the ambient air around the terminal bus lanes. The method used for measuring the concentration of NOx is Griess Slatzman method in accordance with SNI 19-7119.2-2005. The results showed the type of gas-fueled vehicles have the smallest contribution in influencing the value of the NOx concentration measured in bus lanes Terminal Blok M. Value of the correlation relationship between the volume of buses and NOx concentration is 0,055 – 0,856. The results showed that the correlation between the volume of buses with air pollutant concentrations (NO and NO2) is worth very weak to strong. NOx concentrations measured values were well below the standards 400 μg/m3. RQ value calculation results indicate that the stall owners were in the bus lane is still in a fairly safe level of risk."
