Abstract
Coal utilization is a major factor in the formation of energy resources. Therefore, changes in reference coal prices are quite interesting to observe, especially in recent years. The covid-19 pandemic and the surge in foreign demand have caused significant changes in coal prices. This study will evaluate the factors that influence the dynamics of coal prices from 2013 to 2022. The variables analyzed include coal production, domestic coal use, coal trade (exports and imports), and changes in coal prices. The method used in this study is Principal Component Analysis (PCA). The results of the study show that the variables of changes in coal prices, production, exports, imports and domestic consumption show roles that are not much different in the dynamics of coal in Indonesia. However, changes in coal prices are greatly influenced by the amount of coal exports. In addition, domestic consumption, production, and the variables that have the least influence on changes in coal prices are coal imports.
