An Indonesian lowrank coal, Adaro, was hydrothermally treated at 200350°C in an autoclave. The raw and treated coals have been subjected to several analyses which include hygroscopicity, the content of oxygenic functional groups, FTIR spectrum, and specific surface area. When the coal is hydrothermally treated, the hygroscopicity of coal remarkably decreases.

for the mining sector, including coal. Nongovernmental organizations questioned the role of the new regulation in Indonesia's commitment to reducing carbon emissions by 2030 to 29%. Furthermore, the Government of Indonesia added coal mining to the business sectors that are eligible to receive fiscal incentives to reduce the impact of COVID19.
The health and environmental impact of the coal industry includes issues such as land use, waste management, water and air pollution, caused by the coal mining, processing and the use of its addition to atmospheric pollution, coal burning produces hundreds of millions of tons of solid waste products annually, including fly ash, bottom ash, and fluegas desulfurization sludge, that ...
· While geophysical disasters have resulted in more deaths in Indonesia, hydrometeorological disasters have affected more people through injury, displacement, and property damage. Flooding is the most significant hydrometeorological hazard in Indonesia because it occurs more often, affects more people and cause massive and expensive damage.
coal has more than doubled since 2010 to meet rising energy demand, regulations on coal plant emissions remain significantly less stringent than those of other countries in Asia. For example, limits on the concentrations of PM, SO 2, and NO x in Indonesian coal plant emissions are three to times 3 Zhang, X. (July 2016).
"Coal quality" is the term used to refer to the properties and characteristics of coal that influence its behavior and use. Among the coalquality characteristics that will be important for future coal use are the concentrations, distribution, and forms of the many elements contained in the coal that we intend to burn.
The Indonesian coal industry is rather fragmented with only a few big producers and many small players that own coal mines and coal mine concessions (mainly in Sumatra and Kalimantan). Since the early 1990s, when the coal mining sector was reopened for foreign investment, Indonesia witnessed a robust increase in coal production, coal exports and domestic sales of coal.
