The mining system implemented at PT. Berkat Bhinneka Perkasa is an underground mining system. The results from mining the metal mineral commodity black lead ore (PbS/Galena) are helpful in the battery industry, color pigments, ammunition, cable coatings, radiation protection, solder, and other materials that use Pb and Zn as basic ingredients. This research examines the neutralization of acid mine drainage using Tohor Lime (CaO) and Calcium Carbonate Lime (CaCO3). The methods used are survey and experimental techniques, where the survey involves field observations to determine observation points and collect data. In contrast, the experimental method includes laboratory analysis followed by data analysis. This research shows that acid mine wastewater with pH 4.74 and 240.20 ppm Fe²⁺ was effectively treated using quicklime, calcium carbonate, TKKS, and rice husk biochar. These ameliorants significantly increased pH and met the river water quality standards per Government Regulation 22 of 2021. Although active ferrous levels also increased, the effect was not statistically significant. However, excessive ferrous content can harm agricultural soils and plants, potentially causing iron toxicity.

The Earth's surface temperature increases each year due to activities carried out by individuals or companies. Calculating the carbon footprint is one way to determine the emissions generated by human activities. Micro, Small, and Medium Enterprise (MSME) business operators have the potential to contribute to the carbon footprints originating from the use of Liquefied Petroleum Gas (LPG), fuel, and electricity. This research serves as a preliminary analysis to understand MSMEs' GHG emissions from energy and fuel use and identify appropriate strategies to reduce their carbon footprint using a standardized calculation method. This research uses a carbon footprint calculation method based on the methodology established by the Intergovernmental Panel on Climate Change. The analysis results show that the most significant emission sources from culinary MSME activities are restaurants, with approximately 3,079 CO2eq/year, followed by fried chicken at an average of 2,682 CO2eq/year, and meatball soup at around 2,504 CO2eq/year. The MSME with the highest income is fried chicken, with an average monthly revenue of IDR 19,225,000, while the lowest income is from siomay at IDR 7,700,000 per month. Income has an impact of 93.3% on the carbon footprints. Management measures that can be taken include analyzing which stages of the production process require significant energy, so strategies can be formulated to reduce the emissions produced. Additionally, the government should promote carbon-saving movements and educate the public about energy-efficient household appliances.

This study aims to document the traditional knowledge of the local community in Kaloy Village, Tamiang Hulu Subdistrict, Aceh Tamiang Regency regarding the use of medicinal plants for treating circulatory system disorders. The methods used include in-depth interviews, direct observation, and documentation involving 90 respondents from various age groups and two key informants. The results show that the community's trust in medicinal plants remains high, particularly among individuals aged over 50. A total of 10 plant species were identified and used to treat diseases such as hypertension, high cholesterol, anemia, stroke, and diabetes. The most commonly utilized plant parts were leaves and rhizomes, with traditional processing methods such as boiling, pounding, and chewing. The study also calculated the Index of Cultural Significance (ICS) to assess the cultural importance of each species in the community. These findings indicate that ethnobotanical knowledge is still well preserved among the older generation but is beginning to decline among the youth.

Forests play a crucial role in environmental, economic, and social sustainability by storing carbon and mitigating climate change. This study aimed to assess the vegetation composition, diversity, and carbon storage in Gunung Leuser National Park, Bukit Lawang, North Sumatra. Fieldwork, conducted using purposive and nested sampling methods, recorded 11 families and 14 plant species with 27 individuals at the tree growth level, and 11 families and 16 plant species with 30 individuals at the pole growth level. The Burseraceae family dominated tree-level composition (29%), while the Phyllanthaceae family dominated pole-level composition (28%). The highest Important Value Index (IVI) was Santiria rubiginosa (36.09%) for trees and Gironniera nervosa (55.46%) for poles. The Shannon-Wiener Diversity Index (Hâ€™) was 2.45 for trees and 2.53 for poles, with evenness values (E) of 0.93 and 0.91, respectively. The total biomass was 120.240 tons/ha, with stored carbon amounting to 55.310 tons C/ha. To better estimate carbon storage potential, further research should cover larger areas and include biomass components like litter and dead wood.
