This research aims to explore the implementation of the halal ecosystem development through the KHAS (Kuliner Halal, Aman dan Sehat) or Halal culinary is safe and healthy zone in the Lego-lego Area of Makassar. A mixed methods approach was employed, utilizing observation, interviews, and focus group discussions (FGD). The research findings indicate that 60% of visitors are female, while the remaining 40% are male. Sixty percent of visitors come 1-3 times, 25% more than six times, and 15% 4-6 times to Lego-lego. Visitor interest in Lego-lego is attributed to its attractive ambiance and cuisine (50%), recommendations (35%), and strategic location (15%). Satisfaction with implementing the KHAS Zone is reported as follows: 50% satisfied, 30% moderately satisfied, 15% dissatisfied, and 5% very satisfied. One hundred percent of MSMEs tenants in Lego-lego are aware of the KHAS Zone, with exposure coming from seminars (40%), social media (20%), family and friends (20%), media or TV (17%), and management (7%). MSME tenants participate in KHAS Zone development programs/activities such as seminars, halal certification training, halal food training, and management training. The KHAS Zone is deemed adequate by 47%, highly effective by 33%, and less effective by 20% in enhancing the quality of MSMEs. The benefits of the KHAS Zone for MSMEs include improving the quality of halal, safe, and healthy culinary products, increasing income, and raising awareness of product branding and promotion. While the development of MSMEs based on the KHAS Zone has been implemented, comprehensive empowerment from upstream to downstream is deemed necessary for the future.
