The data used in the research is secondary data of the time series type collected from each organizer's publication. The analytical method used is data envelopment analysis (DEA) oriented to the input and output level. The results of this study indicate that during the analysis period, Indonesian airlines have reached the efficiency stage with a relative efficiency score of 1.Industri penerbangan adalah salah satu industri yang bergerak di bidang jasa, serta transportasi udara memiliki tingkat efektivitas yang tinggi dalam hal waktu dari beberapa jenis transportasi lainnya.

Abstract

The relationship between economy, environment, and human capital has developed into a discourse that has attracted the attention of all parties, especially academics. The inconsistency of research results that occur in developing and developed countries is our basis for conducting research with the hypotheses that have been built. This research aimed to determine the effect of human capital and gross domestic product on environmental quality in Indonesia. This study used panel data during the 2015-2020 period. The ordinary least square analysis measures the effect of the independent variables on the dependent one in the model. The results of this study indicate that human capital has a positive and significant impact on improving the quality of the environment. There are several aspects on which human capital can positively affect the environment, one of which is education. On the other hand, an increase in GDP has an inverse effect on the environment. This is because the economy's orientation in developing countries still focuses on the industrialization sector, which negatively impacts the environment. Moreover, this is reinforced by the low level of supervision carried out by the regional or central government.
