Abstract

The mangrove ecosystem on Sicanang Island, Medan Belawan, is facing heavy pressure due to human activities such as land conversion, waste pollution and the impact of climate change. This research uses observation, interviews and documentation methods to identify the factors causing mangrove degradation as well as conservation efforts carried out by the community. The research results show that land conversion into ponds and settlements causes a decrease in vegetation cover of up to 40% in one decade, which has a direct impact on the decline in marine biota populations. In addition, domestic and industrial waste pollution worsens ecosystem damage. However, the local community has initiated various recovery efforts, such as mangrove rehabilitation, sustainable use of resources, and community-based waste management. Collaboration between communities, government, NGOs and educational institutions is key in strengthening conservation efforts and building a sustainable coastal management system.

Abstract

Having a healthy child, both physically and mentally, who grows and develops well is the hope of every parent. However, the birth of children with developmental disabilities, such as Down syndrome, remains a concern that must be addressed, particularly through preventive efforts. Down syndrome is a genetic disorder associated with intellectual disability, often linked to both genetic and environmental factors, including inadequate maternal nutrition during pregnancy. This study aims to develop pedagogical strategies for educating pregnant women on the importance of prenatal nutrition as a preventive measure against Down syndrome. Using a field study method, data were collected through observations and interviews to explore the understanding and practices of maternal nutrition among pregnant women. The findings indicate that adequate nutritional intake during pregnancy contributes significantly to reducing the risk of developmental disorders, including Down syndrome, beyond hereditary factors. The implication of this study highlights the importance of structured and accessible pedagogical interventions to raise awareness and promote responsible nutritional practices during pregnancy. It is hoped that the results can serve as a foundation for future educational programs that empower mothers to make informed decisions for the well-being of their unborn children.

Abstract

River pollution is a serious problem that occurs due to the entry of hazardous substances into river water, thus reducing water quality and disrupting the function of its ecosystem. The main causes of river pollution include indiscriminate waste disposal, industrial waste containing hazardous chemicals, household waste, and unsustainable agricultural activities. This condition causes various negative impacts, such as the emergence of water-related diseases, threats to biodiversity, depletion of clean water supplies, and eutrophication that can kill aquatic organisms. This study aims to determine efforts that can be made to reduce or prevent pollution of the Denai River, by considering the condition of existing water resources. The study was conducted through observation, interviews, and documentation studies. The results of the study indicate that river management is carried out by the governor, for rivers in river areas across districts / cities, in river management is carried out by involving technical agencies and related community elements based on norms, standards, guidelines, and criteria set by the Minister. River management includes river conservation; river development; and control of the destructive power of river water, carried out through the stages of preparing programs and activities; implementing activities; and monitoring and evaluation. River conservation is carried out through river protection activities and preventing river water pollution.
