T The development of the world coking coal market is increasing every year. Thisdevelopment was caused by the increasing demand for the world's steel industry,where coking coal plays a role as the main fuel source in the manufacturingprocess. However, even though the world coking coal market is growing, Indonesiais still unable to seize the opportunity as one of the active exporters of coking coal.To anticipate future developments in world coking coal, it is necessary to estimatethe price of coking coal. Estimation is done by comparing two statistical methods,namely the Autoregressive Integrated Moving Average (ARIMA) and SeasonalAutoregressive Integrated Moving Average (SARIMA) methods. Where the ARIMAmethod (1,1,2) is the best model for price projections. The projection quality iscategorized as Good based on the MAPE testing value (11,6%). The projectionresults can provide an idea about the condition of the world coking coal market andIndonesia's opportunity to become a world coking coal supplier. Indonesia'sopportunities are measured from the condition of resources, reserves andproduction of coking coal in Indonesia and projected coking coal prices. The resultsof an analysis of the development of the coking coal market indicate that there ispotential for market development based on coking coal price movements whichcontinue to increase until August 2025. On the other hand, Indonesia has greatpotential in developing coking coal production due to the abundance of resourcesand reserves in Indonesia with the lack of production in Indonesia.
