Resin is one of the components found in plants. The amount of resin produced by plants will be reflected in the amount of resin that can be observed in coal, both megascopically and microscopically. Coal in the district area. Muara Bungo, Kab. Tebo, and Sarolangun Districts megascopically found resin in quite large quantities and dimensions (reaching a diameter of 20-30 cm). This research was conducted to determine the physical and chemical characteristics of the resin in Jambi coal. Observations using organic petrography and chemical analysis were carried out to investigate the characteristics of the resin. The results of petrographic observations show that the coal samples are formed by very abundant resinite. The chemical composition shows that the resin has a very dominant volatile matter content (generally above 90%) and abundant hydrogen content compared to coal samples in general. The calorie content of resin is relatively high, namely above 9000 kcal/kg (adb). This research will still be continued with funding from other schemes, especially to determine the composition of chemical compounds using gas chromatography - mass spectrometry to be able to accurately determine the clumps of plants that form and the coal deposition environment in the Jambi area.
Knowing the characteristics of coal resin using an organic geochemical approach
This research provides benefits for the development of coal organic geochemistry science. The resin in coal, which has quite large dimensions, can only be found in the Jambi area.
