The discourse on Islamic ecotheology in relation to local traditions offers an understanding that environmental preservation is not merely a technical matter but also carries moral-spiritual and cultural dimensions. Local traditions may therefore serve as a representation of environmental preservation concepts grounded in spiritual values. This study aims to examine and elaborate on the points of convergence between the values embedded in the mattammubulung tradition of Bakaru Village, Pinrang, and the concept of environmental preservation rooted in Islamic values. This research employs a qualitative method with a descriptive-phenomenological approach, focusing on the practices and rituals of the mattammubulung local wisdom and analyzing them through the lens of Islamic ecotheology, particularly the values of amanah-khilafah (trusteeship-vicegerency) and mizan (balance). Data were collected through observation and in-depth interviews. The results of the study indicate that the mattammubulung tradition is a manifestation of ecological awareness built through a harmonious pattern of relationships among humans, the Creator, fellow human beings, and nature. The implementation of Islamic eco-theology in this tradition is tangibly manifested through two main pillars: (a) the concept of amanah-khilafah (trusteeship and stewardship), which reflects the ethical responsibility of humans as leaders and managers of agricultural land based on sustainable utility principles; and (b) the value of mizan (balance), which underlies preventive actions against environmental damage (fasad) to achieve the orientation of common good (maslahah) and ecosystem stability.
