Awareness of environmental health is an important factor in maintaining community welfare, especially in developing urban areas. The city of Medan, as one of the major cities in Indonesia, still faces various environmental problems such as poor sanitation, garbage accumulation, and water pollution, which have an impact on public health. This study aims to analyze the factors that affect the level of public awareness of environmental health in the city of Medan. This study uses a quantitative design with a cross-sectional approach. Data were collected from 100 randomly selected respondents using a structured questionnaire, which measures people's level of awareness of environmental health and various factors that influence it, such as education level, media exposure, and economic status. Data analysis was carried out univariately, bivariately with Chi-square test, and multivariate using logistic regression to determine the relationship between independent variables and the level of public awareness. The results of the study show that factors such as education level, media exposure, and economic status have a significant influence on the level of public awareness. People with higher levels of education, better media exposure, and better economic status tend to have higher awareness of environmental health issues. The implications of these findings suggest that improving environmental education and more effective dissemination of information can be an important effort in raising public awareness. Community-based programs that focus on education and strengthening environmental information can be a strategic step in overcoming environmental problems in urban areas. The results of this research are expected to be a reference for the formulation of more effective policies and programs in increasing environmental awareness in urban communities.
