Abstract

Groundwater balance occurs in the presence of recharge and discharge. The process of entering the water in soil takes place with an infiltration-percolation to aquifers. The groundwater recharge area is identified by lithology, land use, slope, rainfall, land, and landform. Kajor Kulon Hamlet, Selopamioro Village, Imogiri Sub-district, Bantul Regency, Special Region of Yogyakarta becomes an area with hilly morphology, active fault areas, and including drought-prone regions. Change of the land function in hilly areas by making settlements and un-irrigation field for farming may cause decreased ability as a recharge area. Research aim sare to assessing, determining, and analyzing the conditions of the establishment in the research area. The variables used include land use, the slope of the land, rainfall, and soil texture as thematic maps to analysis its land ability. Data collection methods are measurement, inquiry, and mapping. Furthermore, the method of analysis is based on the Geographic Information Systems (GIS) with scoring-weighted overlay method. The results showed the classification of the between low, medium, and high. The medium class is currently occupying 67% of the area in the research area with an area of 719,916.03 m2 . The distribution of each class is expressed through the groundwater recharge area map. The GIS is very efficient and effective in facilitating groundwater recharge area analysis

Abstract

The mining industry has a major influence on the increase in greenhouse gas (GHG) emissions in Indonesia, especially deforestation activities and the use of fossil energy. This makes it important to study the level of greenhouse gas emissions of a mining company so that it can determine the mitigation of reducing GHG emissions released. The research aims to assess the greenhouse gas emission levels in the coal mining services sector at PT Antareja Mahada Makmur. The study provides valuable insights into the environmental impact of coal mining activities, which is crucial for informing sustainable practices and regulatory compliance. The results of this analysis show a significant increase in total A2B and stationary sources (generators) from October 2023 to September 2024 as a source of immobile emissions. The analysis shows that carbon dioxide (CO2) gas is the most dominant component in total emissions from mobile sources (A2B). The findings of this study highlight the importance of mitigation efforts, such as improving energy efficiency and the integration of renewable energy sources, in reducing emissions in the mining sector. This research could help identify gaps and propose improvements to support companies in their mitigation efforts.
