Purpose of the study: The aim is to obtain the original religious data based on local wisdom according to the character and reality of the life of the indigenous people of Dukuh Village. Data collected includes the data on social situations, religious patterns, and nature conservation.
Methodology: The approach used is a qualitative approach with interpretive and ecological methods. Data collection is done through participatory observation, in-depth interviews, library studies, as well as previous studies.
Main Findings: This study finds the reflection of local wisdom of indigenous people at Dukuh Village was built on the platform of "Kasuaran Karuhun", the Islamic religious values, which is collaborated with local cultural values (adat). Subjectively, the output of karuhun is recognised by them as the values of "Islamic custom", so that in managing their environment, their theological awareness should be described in the form of interrelation between God, humans, and nature.
Applications of this study: The relationship between God, humans, and nature refers to the purpose of human life to serve God's willingness at the same time to realise the function of human beings as caliphs on earth in order to build a just and equitable civilisation. Religious-based local wisdom can be an ideal answer to environmental issues by providing a conservation model that favours equality and social welfare and the harmony of an ecologically equitable environment.
Novelty/Originality of this study: Scientifically, this research can contribute to the development of various scientific disciplines, especially to Fiqh al-Bi-ah (Islamic jurisprudence on the environment).
