Sharia Business Law Analysis of Illegal Logging Supply Chains: The Role of Kerik Salamat in Sumbawa Regency

This study aims to analyze the effectiveness of the local wisdom of Kerik Salamat as a preventive social control system in overcoming illegal logging in Sumbawa Regency and examine it from the perspective of Islamic legal sociology. The study uses a juridical-empirical method with an Islamic legal sociology approach through an analysis of positive law, customary values, and social practices of the Tau Samawa community. The results of the study indicate that the local wisdom of Kerik Salamat has an important role in building collective awareness of the community to maintain forest sustainability through the values ​​of living safely, securely, and in harmony with nature. From the perspective of Islamic law, these values ​​are in line with the principles of al-‘adah al-muhakkamah and maqāṣid al-sharī‘ah, especially in the protection of life (ḥifẓ al-nafs), protection of public property (ḥifẓ al-māl), and environmental protection (ḥifẓ al-bi’ah). This study also found that synergy between state regulations, customary institutions, religious leaders, Forest Management Units (KPH), and the strengthening of the green economy through the utilization of Non-Timber Forest Products (NTFPs) such as Sumbawa Forest Honey can strengthen participatory community oversight of forest areas. Thus, the integration of positive law, local wisdom, and Islamic values ​​can become a model for combating illegal logging that is preventative, participatory, and sustainable in order to maintain the sustainability of forest ecosystems and community well-being.
