The decreasing interest of the younger generation in agricultural activities poses a serious challenge for future sustainability. Integrating environmental education into early childhood learning is therefore essential. This community service activity aimed to introduce eco-friendly farming practices to preschoolers at TK ABA XVI, North Purwokerto, Banyumas Regency through a simple hydroponic system using recycled waste materials. The program involved interactive lectures, discussions, Q&A sessions, and hands-on hydroponic planting. Results showed an increase in students' knowledge about hydroponics and a growing awareness of the importance of recycling plastic waste to protect the environment. This initiative highlights the effectiveness of early intervention in cultivating environmental consciousness among young learners.
