Introduction One of the biggest contributors to natural disasters in Indonesia is the country's environmental management problems (Ramadhany, 2023). Development carried out without considering environmental balance considerations, which will result in environmental damage and pollution is the source of all environmental problems (Rosmaida & Triadi, 2024). According to the data in 2018, Central Bureau of Statistics indifference index towards Indonesia's environment showed a value of 0.51. This figure shows that awareness is still low or ignorance is quite high. Public ignorance of the environment is feared to lead to the destruction of natural resources and eventually trigger natural disasters. Many factors influence the issue of public environmental awareness. People's lack of understanding of human nature as a multidimensional being contributes to the current situation by making people less aware of their responsibility to always maintain the balance of nature and humans. Environmental damage is also influenced by the number of the population. People's lack of environmental literacy contributes to environmental degradation (Nakita & Najicha, 2022; Rijal & Amprasto, 2018). Abstract Community service activities are a mandatory responsibility for university lecturers as part of the Tri Dharma. This research aimed to investigate attitudes and behaviors towards environmental conservation and analyze the impact of theme- based learning on children in Sei Tuan Village, contributing to broader community-level efforts to protect and preserve the environment. A mixed-methods approach was employed, involving both qualitative and quantitative paradigms to collect and analyze data from 13 children residing in Sei Tuan Village, Deli Serdang Regency. A Pre-Test – Treatment – Post-Test methodology and observations were utilized in conducting the research. The results revealed that 85% of children in Sei Tuan Village demonstrated proficiency in distinguishing between healthy and unhealthy environments. Additionally, all individuals exhibited concern for the environment, including methods of preservation and the benefits of a pristine environment. Notably, 77% of students received comprehensive instruction on categorizing trash into organic, inorganic, and hazardous types. Moreover, 88.5% of individuals articulated positive effects resulting from nurturing environmental affection. Theme-based learning was found to enhance children's recognition of environmental and climate change issues, sparking their interest in learning, particularly in applying basic English vocabulary to care for and protect the environment.
