Abstract

This study investigates the relationship between heavy metal pollution and environmental policy through a bibliometric analysis of research published between 2009 and 2023. Heavy metal contamination, involving toxic elements such as lead, cadmium, and mercury, poses significant risks to human health and ecosystems, particularly in areas of intensive industrial activity. The study aims to assess research trends, policy advancements, and collaborative networks to identify gaps and propose future directions. Data were extracted from Scopus, employing keywords like “heavy metals” and “environmental policy”. Biblioshiny software facilitated analyses of publication trends, geographic distribution, co-authorship networks, and citation impact. The findings reveal a marked increase in research output from 2015, driven by international policy initiatives like the Minamata Convention. China leads in publication volume, reflecting its industrial challenges, while other nations like India and Brazil emphasize collaborative efforts. Keyword analyses highlight themes such as health risks, pollution monitoring, and policy evaluation. The study underscores the critical role of global cooperation in addressing pollution through innovative technologies and effective policies.Future research should explore the impact of climate change on heavy metal mobility, long-term health effects, and the integration of AI and IoT in environmental monitoring. These steps are vital for advancing sustainable solutions to mitigate heavy metal pollution.

Abstract

This study aims to identify and analyze mitigation and adaptation to natural disasters carried out by the Mentawai tribe. This study uses a qualitative research type with an ethnographic approach. Determination of informants in this study used the snowball sampling method, a sampling technique that starts with a small number then develops along with the data collection process. Data collection techniques: direct observation in the field, interviews, documentation, and literature studies. Data analysis was carried out through the stages of data collection, data reduction, data presentation, and drawing conclusions. Results of this study indicate that there are two models of natural disaster mitigation based on local wisdom, namely the stilt house (Uma) which is located in coastal communities and arat sabulungan which is located in hilly communities. Local wisdom of Uma which is located in coastal areas is used and trusted for mitigating earthquakes, tsunamis and floods. Local wisdom of arat sabulungan for mitigating landslides in the Mentawai hills. This study also shows structural adaptation strategies, socio-cultural adaptation and economic adaptation of the community in dealing with natural disasters in the Mentawai Islands region. Conclusion is that with local wisdom, communities are able to maintain the existence of their lives.

Abstract

This study aims to assess the carrying capacity of the Anai River Basin (Watershed) in West Sumatra Province in response to increasing anthropogenic pressures and environmental changes. The research employed a spatial analysis approach utilizing remote sensing data and geographic information systems (GIS) to evaluate land cover conditions, water quality, and erosion levels. Carrying capacity analysis was conducted by calculating an environmental carrying capacity index, which included hydrological aspects, water quality, and the ecosystem's capacity to provide environmental services. The results indicate that the Anai River Basin is experiencing significant ecological pressure from land use changes, particularly the conversion of forests into agricultural land and settlements. Erosion rates in several sub-watersheds reached moderate to severe categories, with an average value of 15-25 tons/ha/year. River water quality demonstrated a decline in several parameters, especially increased turbidity levels and sediment content during the rainy season. The hydrological carrying capacity of the Anai watershed remains in a moderate category (index 0.65) but has shown a declining trend over the last five years. The findings indicate the necessity for implementing sustainable watershed management strategies. Management recommendations include forest conservation in upstream areas, the application of soil and water conservation techniques on agricultural land, the development of a regular water quality monitoring system, area zoning based on vulnerability levels, rehabilitation of 2,500 hectares of critical land, and the strengthening of watershed management institutions involving the active participation of local communities.
