Abstract : With this research, we want to better understand how exchange rates, interest rates, Indonesian coal reference prices, and oil prices about the valuation of coal firms that are publicly traded on the Indonesia Stock Exchange (IDX) for the period 2018-2023. Using a quantitative approach and multiple linear regression analysis, this research evaluates the effect on firm value. The analytical results demonstrate that exchange rates significantly impact firms value, while interest rates, coal reference and oil prices with firm value.

Tax avoidance refers to the legal strategy employed by companies to minimize tax obligations by exploiting loopholes in tax regulations. While lawful, such practices often raise concerns due to their potential impact on state tax revenues.

The state has moved away from the direct ownership model in many industrial sectors. Nonetheless, large state-owned enterprises (SOEs) still dominate key sectors such as energy and infrastructure, and the state continues to intervene heavily in many other sectors using its control of credit, land, and natural resources.

Considerable interest has been developed over the past few years in the application of gas turbines to expand the hot, dirty flue gases from pressurized fluidized-bed combustors (PFBCs) burning coal. Although no full-size gas turbine has yet operated on a PFBC, firm commitments have been made to build commercial PFBC-GT power plants. In addition, there are a number of projects at various stages of development aimed at operating gas turbines on dirty fuels ranging from the expansion of flue gas from the combustion of pulverized coal, to the direct firing of coal-water mixtures. Common concerns

In accordance with the latest trends, considerable emphasis is put on all mining companies in the Czech Republic not only on reducing the environmental impact of brown coal mining, but also on overall efficiency, the balance of which can be improved by increasing of the operational reliability of individual components of technological units and reducing operating costs. And it is the latter sphere, in that Vrsanska uhelna a.s. does considerable initiative. In cooperation with the firm RENOMAG s.r.o. and the Research Institute for Brown Coal a.s. carries out the development and laboratory and i

As of 2004 and continuously to this day, the annual growth rate of renewable sources has been greater than that of all fossil fuels combined. In the midst of this transition to cleaner energy, natural gas is the only fossil fuel that has increased its share in the global energy matrix. Technological changes in the LNG supply chain, as well as transformations in the global natural gas market, largely explain this growth. This publication provides evidence on the fundamental role that natural gas plays in the energy transition, given that: (i) its greenhouse gas emissions are substantially lower

For the first time, a Chinese company—Huawei—is set to lead the global transition from one key national security infrastructure technology to the next. How did Washington, at the beginning of the twenty-first century, fail to protect U.S. firms in this strategic technology and allow a geopolitical competitor to take a leadership position in a national security relevant critical infrastructure such as telecommunications? This policy brief highlights the characteristics of 5G development that China leveraged, exploited, and supported to take the lead in this key technology. The Huawei case study

Attic fires pose many hazards for the fire service. When a fire occurs in an attic, it is common it goes unnoticed/reported until smoke or flames are visible from the outside of the structure. Because they take longer to detect, attic fires are more dangerous for firefighters and residents. In a fire situation, the attic ventilation system, which is designed to reduce moisture accumulation by drawing fresh air low from the eaves and exhausting moisture laden warm air near the peak, create an optimal fire growth and spread situation by supplying oxygen to the fire and exhausting hot gases.
