Indonesia is one of the largest coal producers and exporters in the world. Since 2005, there have been many small pockets of coal reserved on the islands of Sumatra, Java, Kalimantan, Sulawesi and Papua. This makes Indonesia increasingly utilize all natural resources that have existed in the ancestral lands to make coal energy sources as a Steam Power Plant (PLTU) in addition of abundance basic materials, this coal-based PLTU is considered to have better efficiency in terms of price. Cheaper and faster in process compared to other energy sources.
Behind the efficiency of coal, which is used as the main fuel, there is a process that is considered ineffective for local residents and the surrounding environment, because in PLTU, coal is burned to take heat and steam, so it can release combustion residue in the air. From this combustion residue, it will spread to aquatic plants or enter the human lungs. Coal is burned to take heat and its steam releases combustion residue in the air. The remainder of this combustion will spread to aquatic plants or enter human lungs.
In the theory, all of this has been filtered so that the smoke that comes out is not dangerous, but the reality can be different from the facts in the field.
Inside the PLTU smoke, there are pollutants which contain dangerous compounds such as mercury and other compounds such as arsenic, lead, PM 10, sox and PM 2.5. These particles stay in the air for a long time and can fly hundreds of kilometers. If humans are exposed to mercury or pm 2.5 continually, there will be asthma, respiratory infections, lung cancer and even damage to the brain, kidneys and heart. It is clear that the air environment and settlements are not good for local residents due to the danger of compound content that will threaten the health of the surrounding community, especially since the PLTU distance from residents’ settlements is not a safe distance. This is evidenced by the case that occurred in November 2018, Sangah Sangah village Kutai Kartanegara, East Kalimantan, experienced 5 houses destroyed, 11 others were damaged and the main road collapsed due to mining activities that were too close to public facilities and settlements.
Kalimantan, Borneo, some of farmers in the suburbs of Samarinda Timur have lived for 20 years as neighbors that are very close to the coal mines in this village. Meanwhile, according to the regulations of the minister of environment and regional regulations Kutai Kartanegara the minimum distance between mining activities and settlements is 500 M but in fact, all of the regulations are not applied. While the existence of a coal-fired PLTU has made clean water is only a history. The residents stated that they only relied on rainwater and water from the emblem that brought along the silt Previously, before there was a coal mine, the rice fields were not damaged, the environment was beautiful and safe, but the situation drastically changed since the coal power plant, residents’ crops such as rice fields and so on were exposed to mud so that they produced plants that were not of the same quality as before.
This is very unfortunate because in 1991 this village was designated as a village of rice barns with a production of 2600 tons of unhulled rice in every harvest time. Disappointment and despair began to appear on the faces of the villagers who felt the problems that were increasingly choking local residents, not only polemic about the environment and plants. The existence of a coal company and a PLTU have also claimed the lives of several villagers due to the reclamation of coal mines.
The local community certainly did not remain silent, so they filed a protest by one of the residents of Nyoman Derman from Kertabuana Village, Kutai Kertanegara Regency. Nyoman intercepted heavy equipment but was instead arrested and given a 3-month prison sentence on the grounds of disrupting company operations. When the community takes an active role to defend and protect all assets owned by the government, the government does not protect. On the contrary, this is not in accordance with the constitution of our country which upholds human rights which are emphasized in the 1945 Constitution in article 27 to article 34 of the 1945 Constitution which regulates Human Rights.
The problems do not end with environmental problems but also at the same time claiming the lives of many local residents. The excavation of ex-coal mining holes resulted in many human lives being lost, among others in 2011-2018 in East Kalimantan as a result of the mining excavation hole itself. At least, it has been claimed the lives of as many as 39 people. Between 2014-2018 nationally, there were 115 people who died as a result of mining holes
This can’t be underestimated into an ordinary problem caused by the longer, it continues to claim casualties due to 3,500 former mine pits that have not been properly filled so that it continues.
