Abstract
Religious teachings have long emphasized environmental stewardship, with many Islamic principles advocating sustainable living and conservation efforts. In Indonesia, where religiosity is high, faith-based education plays a crucial role in shaping environmental awareness. This study analyses the Arabic language curriculum in madrasas and pesantrens to explore how environmental values are integrated into Arabic language instruction. Currently, only two explicit environmental themes are found in textbooks, indicating a gap in curriculum development. Using curriculum and literature analysis, this research proposes strategies such as enriching textbook themes, developing environment-focused modules, providing teacher training, and implementing project-based learning. The findings demonstrate that Arabic language education can serve as an effective medium for fostering environmental awareness based on Islamic teachings. Integrating these values not only enhances the relevance of Arabic instruction but also cultivates a generation that is both religiously devoted and environmentally conscious. Recommendations are provided to strengthen the Arabic curriculum as a tool for building environmental awareness in madrasas and pesantrens.
