While this adoption has the potential for significant benefits, various barriers must be investigated. This study examines the barriers to adopting halal supply chains in small and medium-sized food enterprises (SMEs). The fuzzy analytical hierarchy process (fuzzy AHP) assesses and weighs the 30 identified barriers. The results showed that the main barriers to adopting a halal supply chain include understanding and awareness of the importance of halal certification, support from the government and related institutions, and companies' internal readiness to implement halal standards. In addition, other significant barriers were high certification costs, lack of funds to promote the halal industry, lack of willingness to adopt and implement halal in the supply chain, and lack of technology costs to manage supply chain processes by halal standards. The implications of this study suggest the need for better support strategies from the government and relevant agencies, as well as awareness and understanding-raising efforts among SMEs to overcome these barriers and facilitate the adoption of halal supply chains.

INTRODUCTION In recent years, adopting the halal supply chain in small and medium-sized food enterprises (SMEs) has become a key focus in improving business performance and ensuring product halalness [1], [2]. Adopting a halal supply chain is essential for food SMEs to improve their operational performance and ensure their products comply with established halal standards [3], [4]. By Islamic law, every Muslim must ensure that the food consumed is completely halal [5]. Therefore, food SMEs must ensure that the entire process of producing, shipping, and storing their products complies with applicable halal standards [6], [7]. Implementing the halal supply chain can help SMEs manage the supply chain effectively while increasing consumer confidence in the halal products they offer [8]. Thus, adopting the halal supply chain is an important strategy to improve business performance and ensure that the products sold meet halal criteria [9]. Identifying the barriers that hinder the adoption of halal supply chains among SMEs in Indonesia is essential as it can improve the halal integrity of food products [10]. The demand for halal food has increased domestically and internationally in recent years [11]. However, many SMEs still experience difficulties integrating halal principles into their supply chains, which can raise doubts regarding the quality and halalness of the products [3]. Therefore, conducting an in-depth analysis of the barriers hindering halal supply chain adoption in SMEs is necessary. This analysis aims to increase SMEs' awareness and ability to
