Coal is a cheap and abundant natural resource. Coal is generally used as a fuel for steam power plants (PLTU). Total world coal reserves in 2017 reached 1.035 trillion tons consisting of 718.3 billion tons of anthracite and bituminous coal types and 316.7 billion tons of sub-bituminous and lignite coal ^[1] . America, Russia, China and Australia are the countries that have the most coal reserves compared to other countries. However, Russian coal production is smaller than countries that have less coal reserves such as India and Indonesia as shown in Table 1. >>> 

Congestion or traffic jam is one of the main problems in cities around the world. Motorized vehicles are easier to obtain while roads are increasingly difficult to widen. The drivers also do not know which is the best road they should choose because traffic is difficult to predict. One solution is to use CCTV to monitor, but this solution requires considerable human resources and costs. For this reason, Dwi Aji Kurniawan, a UGM student, along with two of his supervisors, tried to solve this congestion problem by utilizing one of the social media, namely Twitter. This research initially became the topic of the student’s thesis, but also made it into the ICITEE ( International Conference on Information Technology and Electrical Engineering) 2016. Even so, why choose to use Twitter? >>> 

Amid growing climate change issues and increasingly severe air pollution, efforts to transition from fossil fuels to clean energy are continuing. Of the clean energy modes available, renewable energy gets the biggest attention. Solar panels and wind turbines are considered to be the Messiah for planet Earth. >>>
