Abstract

Air quality in DKI Jakarta is currently trending. On August 10, 2023, Jakarta was ranked as the city with the worst air quality in the world. This condition causes a lot of anxiety among the public and disrupts health. Therefore, people in the capital city are asking the government to act quickly and precisely to overcome the problem of poor air quality. The response given by the government to deal with air pollution in DKI Jakarta is to provide several policies. Starting from August 11 until the end of August 2023, the government will issue up to 7 policies that are expected to overcome the pollution problem in the capital city. This research wants to see whether there is a difference in air quality in DKI Jakarta before and after the follow-up provided by the government. Daily recorded air quality index data is taken from a database, namely AQAIR. The data obtained was analyzed using the Mann-Whitney Test to see whether there were differences before and after the government issued the policy. After analyzing the data, the results showed that there was not sufficient evidence to state that there were significant differences related to air quality in DKI Jakarta before and after the policy issued by the government. Based on this, it seems that the policies issued by the government to overcome pollution are still not enough or not appropriate. Therefore, other alternative solutions are needed so that air quality problems can be resolved as soon as possible.

Abstract

The Human Development Index (HDI) is an indicator to measure success in improving the quality of human life. The utilization of HDI indicators can be used to classify observations into clusters based on several aspects, such as health, education, and economy. The results of the clusters can be used as a reference for evaluating government policies. This study uses HDI indicator data in the East Nusa Tenggara (NTT) Province, which consists: Life Expectancy, Average Years of Schooling, Expected Years of Schooling, and Per Capita Expenditure. The outliers were detected in each variable. Therefore the k-medoids clustering method was used in this study because of their robustness on outliers. The clustering results show that there are 4 clusters formed, with each cluster describing a unique character. Cluster 1 describes the condition of the districts in general. Cluster 2 describes the condition of the districts that are one step ahead of others, which are expected to transform into cities in the future. Cluster 3 describes the condition of the district that needs more attention from the government in all sectors because all the HDI indicators are on the lowest value comparing to the other clusters. On the other hand, cluster 4 describes urban areas which have more developed than other areas, in terms of health, education, and economy. The clustering results can be used as a suggestion for evaluating government policies that have been implemented, in order to create structured equitable development based on data and regional characteristics as well.
