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.

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%
The purpose of this study is to determine the distribution of total coliform and Escherichia coli as a biological indicator within groundwater, located in Kebayoran Baru, South Jakarta, Indonesia (6° 14' 37.039" S 106° 48' 0.504" E). Total coliform and Escherichia coli are bacteria whose presence can be indicated from contaminated water by human faeces or animal waste. The method used for sampling was done by stratified random sampling techniques. In this random sample of stratification, it is divided within several segments based on the categories. Sampling is divided according to area and each sample is collected based on income which are divided into three groups, namely, high income, medium income and low income as many as 24 sampling points. The presence of total coliform and E. coli was calculated using Most Probable Number method and ArcGIS Program to process bacterial distribution pattern. The results of this study showed that in all groundwater samples containing coliform and E. coli, it was only found within sampling points that ranged from 6 MPN/100 ml up to 1100 MPN/100 ml. Whereas E. coli bacteria in ground water ranged from 0 MPN/100 ml up to 263 MPN/100 ml are not found
