Abstract

Climate change results from global warming, caused by increasing greenhouse gases in the atmosphere, especially CO2 (carbon dioxide). This increase cannot be separated from the excessive use of fossil fuels such as oil and coal in the energy sector. In addition, mining can cause environmental damage, such as reduced air and water quality, and exacerbate future climate change. Renewable energy can be a solution to meet electrical energy needs by minimizing the impact it causes. Solar energy is one environmentally friendly source of renewable energy that will never run out. An analysis of climate change and the potential for solar energy has been carried out in this study. Data processing results for the last 30 years (1992-2021) show that climate change has occurred in the monsoon region. This is marked by a significant increase in the annual average temperature trend and an increase in extreme minimum temperature events until 2021. Based on the results of the projection of solar energy potential using the RCP4.5 scenario for the monsoon region until 2050 of 4.56-5.03 kWh/m2.day with homogeneous data distribution.

Abstract

Coal mining activities are long-term activities, involve high technology and are capital intensive. Mining activities cause potential changes in the income of people who work as rubber farmers due to damage to the landscape and land conversion that affect rubber production. The research aims to analyze the impact of coal companies on the environment and the local economy of the people around Padang Batung sub-district and Sungai Raya sub-district, Hulu Sungai Selatan district, South Kalimantan. This research was conducted in Hulu Sungai Selatan District, Padang Batung District and Sungai Raya District which included 3 villages namely Malutu Village, Ida Manggala Village and Batang Kulur Kiri Village. Analysis of the impact of coal mining is carried out on 2 parameters, namely environmental and economic parameters. The environmental components that are of concern to the community at the study site are air quality degradation (increased dust), river water pollution, increased noise, emissions from heavy equipment and transport exhaust gases and waste water. Coal mining activities in the Padang Batung District and Sungai Raya District are able to have a positive economic impact on local communities with a multiplier effect value of 1.01 in 2021. The direct economic impact of coal mining activities is Rp. 4,336,921,464, indirect economic impact of Rp. 1,132,608,000 and the economic impact is Rp. 714,468,000.

Abstract

Coal mining activities using the open pit mining method can affect depreciation of the quality of the surrounding environment, one of which has an impact on reducing the classification criteria for soil chemical properties. The soil organic matter shrinks after being mined due to the lifting of the top layer due to the dismantling of the coal covering material. The research objective is to analyze the effect of mining activities on soil classification in the disposal area. The research method is descriptive analysis. Sampling and observation in Cintapuri Village, Cintapuri Darussalam District, Banjar Regency. Soil classification in Disposal 1, soil pH is classified as "Very Acid" to "Sour", C-organic is classified as "Very Low", N-Total is classified as "Very Low" to "Low", phosphorus is classified as "Very Low", Cation-exchange capacity (CEC) is classified as "moderate". Disposal 2, Soil pH is classified as "acid", C-organic is classified as "Very Low", N-Total is classified as "Very Low" to "Very Low", phosphorus is classified as "Very Low", CEC is classified as "Medium" and "High". Based on the research, the existence of coal mining activities causes the chemical properties of the soil in the disposal area as low criteria.
