Waste is divided into two types: organic and non-organic waste. Organic waste is biodegradable and comes from living organisms, such as food scraps, dry leaves, and vegetables. Meanwhile, non-organic waste is difficult to decompose and originates from non-biological materials such as plastic, glass, metal, and paper. The socialization activity on the segregation of organic and non-organic waste was carried out at SDN Impres 034796 Silalahi I Village, Silahisabungan District, Dairi Regency, as a form of community service. This activity aimed to improve students’ knowledge and awareness of the importance of waste segregation to maintain environmental sustainability. The methods used included material presentation, interactive question-and-answer sessions, and watching educational videos about organic and non-organic waste. The results showed that before the socialization, students were not able to distinguish between organic and non-organic waste and still disposed of waste in a single bin. After receiving the material and practical demonstration, students demonstrated improved understanding, as reflected in their ability to identify biodegradable and non-biodegradable waste. Students enthusiasm and active participation during the activity became indicators of the program’s success.
