Abstract: This study conducts a comprehensive evaluation of the quality parameters of Indonesian coal.
Drawing on the company,s coal resources，it compares the quality of Indonesian coal with that of fat
coal，coking coal，and 1/3 coking coal，thereby dissecting their respective strengths and weaknesses.
The study attempts to substitute a portion of the 1/3 coking coal and coking coal with Indonesian coal in
the coal blending for coking purposes. The findings indicate that the utilization of Indonesian coal as 1/3
coking coal in coal blending not only stabilizes the quality of the coke but also contributes to a reduction
in ash content.

Key words: Indonesian coal, Evaluation of coal quality, Coal blending
