The study was conducted at two locations, namely in the Massenrengpulu Region of Bone Regency and Pujananting Region in Barru Regency. The research method used is the collection of field data each using the channel sampling method (ply by ply), which represents the lower layer, middle layer and upper layer. Then a proximate analysis is performed to obtain a fixed carbon content and an analysis of the calorific value. The results of the analysis show that, coal in the Pujananting area shows a correlation between the percentage of fixed carbon and the calorific value has a very good correlation with the linear regression value of 0.9994. Similar to the Mallawa Formation coal in the Massenrengpulu area, the correlation of fixed carbon content and calorific value shows a very good correlation with a linear regression value of 0.9998. An increase in the percentage of fixed carbon in coal will be followed by an increase of calorific value. This increasingly shows a very strong correlation between fixed carbon content and calorific value in coal. ## Keywords - Heat of combustion - Coal - Proximate - Carbon fibers - Environmental science - Value (mathematics) - Mathematics - Statistics - Chemistry - Waste management - Engineering - Combustion - Algorithm - Food science - Composite number - Organic chemistry --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
