Currently, the government is increasingly building PLTMG to fulfill the electricity needs of the society. Beside for fulfill the electricity needs of the Indonesian people, PLTMG also has a negative impact on the society, especially for the community around the PLTMG in the city of Batam. So companies need to conduct studies on environmental impacts, one of which is the impact of the air produced on the surrounding area. The PLTMG industry does not use air pollution control devices, but uses a leanox combustion control system on each gas engine with a chimney outlet that emits SO2 and particulate emissions. The model simulation was carried out using Aermod view software with meteorological data from the affected locations. The results of AERMOD modeling show that the PLTMG industry will have an impact on particulate emissions in the ambient air around the activity location which will spread to the northwest, north, south and east of the activity location. The Aermod Model also shows that current conditions have resulted in dispersion with concentrations below the maximum limit stated in the 2021 Government Regulation. The addition of an emission monitoring system such as CEMS can be used to help monitor the concentration of dispersed emissions. Apart from that, emission control devices such as incinerators or combustion can also be used to reduce the concentration of the emissions used.

Healthcare waste (HCW) is a significant environmental and public health concern due to its hazardous nature, particularly the presence of emerging pollutants such as pharmaceuticals, heavy metals, and pathogens. The improper disposal and management of healthcare waste contribute to pollution and pose long-term risks to both human health and ecosystems. This study examines the toxicity risks associated with HCW in areas near healthcare facilities with inadequate waste management practices, showing an increase in toxicity risks by 22% to 30%. The research develops a cumulative risk assessment model that integrates human exposure with ecological risks, considering both direct and synergistic effects of pollutants. The model incorporates various components, including pollutant analysis, bioaccumulation mapping, and long-term exposure modeling, to assess the environmental and health risks of HCW. The findings highlight that inadequate waste management leads to significant pollutant accumulation in local ecosystems, with direct implications for biodiversity and human health. Additionally, the study emphasizes the benefits of applying the One-Health approach, which considers the interconnectedness of human, animal, and environmental health, offering a more integrated understanding of the risks posed by HCW pollutants. The research advocates for the incorporation of the One-Health model in healthcare waste management policies to mitigate risks and improve sustainability. Future studies should refine the cumulative risk assessment model and expand it to encompass other environmental waste sources, providing a more comprehensive understanding of pollutant impacts and advancing mitigation strategies.
