International Journal of Academic and Applied Research (IJAAR)   Year: 2023 | Volume: 7 | Issue: 3 | Page No.: 13-18 Prediction of Carbon Monoxide Pollutant Levels Average in DKI Jakarta Province Using the Ordinary Kriging Method Download PDF Syehvira Shal Shabilla, Toha Saifudin, Nur Chamidah, M. Fariz Fadillah Mardianto, Siti Maghfirotul Ulyah Abstract: DKI Jakarta is the most densely polluted city in Indonesia according to the 2021 IQ Air report. The main source of pollution in DKI Jakarta is caused by transportation emissions. Even though transportation emissions are the largest sector producing CO pollutants, it even reaches 70.5%. The pollutant carbon monoxide (CO) is also the most dangerous pollutant according to research by the New Jersey Department of Environmental Protection. On the other, DKI Jakarta only has five monitoring points for CO levels. Therefore, predictions are made at location points that are not sampled to better represent the condition of CO pollutant levels in DKI Jakarta. This study aims to provide information to the public and the government to immediately take preventive and anticipatory steps. The results showed that the best prediction of CO pollutant levels using the Ordinary Kriging method was exponential with a Mean Absolute Percentage Error (MAPE) of 10.001% which means it has good accuracy. The prediction results for the 44 districts as a whole are within the threshold. There are 26 sub-districts included in the unhealthy for sensitive groups category and 18 sub-districts included in the category. Thus, the government still has to pay more attention to optimizing the reduction of air pollution, especially due to CO pollutants.
