Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

Radius of an electron is estimated about 2 x 10-10 cm, this radius is assume to be rest radius of electron but when electron absorbed the energy from external sources (photon) the radius of electron goes to increases by +x while emitting the energy the radius of an electron goes to decreases –y. This increasing and decreeing take place because electron is constituent of particles. That mean electron is a single system, which on absorbing the energy the constituent particle goes on vibration and this vibration causes the electron to expand the radius. While in emitting the energy, the constituent particle reduces the vibration and this reduces vibration causes contraction of radius of electron. But the radius of electron which is not goes on energy absorption phenomena they have constant estimate radius about 2x10-10cm. Hence the radius of the electron is also depend upon the energy absorption or amount of energy incidence on electrons
The 18th ASIAN Games was held in Jakarta in August 2018. Growth in the number of motor vehicles in Jakarta is 8% per year in the last five years. Gas emissions from motor vehicles contain air pollutants with the highest percentage of carbon monoxide (CO) 70.5% and Particulate Matter (PM) of 1.33%. Although the percentage of PM is small, this pollutant has a harmful impact on respiratory health compared to other pollutants. The purpose of this study is to analyze CO and PM2.5 concentrations during the Asian Games and compare with Indonesia National Ambient Air Quality Standards (NAAQS), to analyze each type of motor vehicle volume with emission load, and to analyze the correlation between CO and PM2.5 concentrations with the emission load. The research method was applied by collecting primary data during the Asian Games using ITX multi gas monitor for CO and Particle Counter HT-9600 for PM2.5. The vehicle volume was counted by using IHCM conversion and the emission load by emission factor from Ministry of Environment and Forestry (MoEF). The results showed the highest average ambient concentrations of CO and PM2.5 occurred on weekdays, respectively 11ppm and 35μg/Nm3 . The CO concentration has exceeded the NAAQS. The highest vehicle volume is the motorcycle with the highest CO emission load, followed by gasoline-fueled cars. The correlation between vehicle volume and PM2.5 emission load was 19.3% and for CO was 38%
