Waste that is not managed properly has a negative impact on the environment, including in the school environment. In Gonilan Village, there are already several waste banks, but there is no waste bank in schools. This community service aims to provide teachers with a guidebook for managing waste banks in schools so that they can give examples to students. The method used is providing material in the form of a guidebook containing the definition, purpose, benefits of waste banks, types of waste, 3R principles, waste bank system mechanisms, and waste management flows. Educational activities at SDN Gonilan 2 went well, marked by positive responses from all participating teachers. The guidebook was appropriate, easy to understand, and suitable for use. This success was supported by the active participation of teachers, the suitability of the material, and the book's feasibility test process. However, there are challenges such as the need for broader follow-up information on waste management, a comprehensive deepening of the management cycle, and the provision of more interesting examples and illustrations to motivate readers. Based on the evaluation using a questionnaire, it can be concluded that the waste bank management guidebook was considered effective as an educational medium by SDN Gonilan 2 teachers in improving waste management in schools. This is demonstrated by the teacher's positive responses to the appropriateness of the content, ease of understanding, suitability of use, and potential for increasing motivation offered by the guidebook.
