Through SWOT analysis, the study assesses the strengths, weaknesses, opportunities, and threats related to interfaith relations in Kedang, proposing strategic measures for reinforcing religious harmony. The findings contribute to a broader understanding of cultural and religious dialogue, offering a model for promoting peace and unity in diverse communities, both within Indonesia and globally.
