Furthermore, language learning not only aims to develop language skills, but also contains knowledge that is useful for students and the environment, one of which is environmental education. The purpose of this research is to develop task-based digital teaching materials with environmental education. The type of research used is development research using the Plomp Model (Preliminary Research, Prototype Phase, & Assessment Phase). The data analysis technique used in this research is descriptive data analysis technique. The results showed that it is necessary to develop teaching materials for language learning. Based on the teacher's response to the teaching material model, it shows a positive response to be used in learning
