Background: Efforts to protect the surrounding environment must start by oneself by doing small things. Education to students regarding environmental problems caused by landfills is needed to raise students' awareness so that they care more about the surrounding environment. Active participation of students can be carried out in the culture of disposing of waste in the appropriate place and according to the type of waste. This activity aims to increase environmental knowledge and awareness among children through video animation-based waste management education at the At-Taqwa Bulakan landfill. Methods: This community service activity utilised a pre-post test design to evaluate knowledge improvement. The target participants were students in grades 3–6 of elementary schools. Participants were selected using saturated sampling based on inclusion criteria, resulting in 18 children participating in the activity. Results: The results showed that there was an increase in participants' knowledge before being given the counseling with a p value of 0.032. The mean pre-test score of participants was 66.11 (SD 4.26) and the mean post-test score was 74.44 (SD 4.99). Conclusion: Counseling using animated video-based learning methods can be considered successful in increasing understanding and skills about the importance of maintaining the surrounding environment free from rubbish for children. Animated videos are recommended as an effective environmental education medium and should be integrated into children's education programmes to shape waste-conscious behaviour.
