BUILDING RURAL ECONOMIC ECOSYSTEMS THROUGH A COMMUNITY-BASED COIN BARTER MECHANISM: A CASE STUDY AT LADANG EDUKASI, SEI MENCIRIM, MEDAN

Abstract

This study examines an innovative community-based economic model implemented at Ladang Edukasi in Sei Mencirim, Medan, where a unique coin-based barter system stimulates local transactions. Unlike formal currency systems, this mechanism utilizes specially designed coins as a medium of exchange within a curated bazaar ecosystem. Visitors exchange cash for coins at a central counter, which are then used to purchase products from local micro-enterprises (UMKM). In turn, UMKM participants contribute a small percentage of their earnings as a venue fee. Qualitative observation and stakeholder interviews reveal that this model enhances local economic engagement, fosters a sense of community ownership, and creates a self-reinforcing cycle of rural economic vitality. The coin system serves not only as a transactional tool but also as a social innovation that strengthens resilience, encourages sustainable consumption, and aligns with Islamic economic principles such as fairness, transparency, and shared prosperity. This study concludes that community-driven barter mechanisms can serve as effective, low-cost strategies for revitalizing rural economies and promoting inclusive growth in the post-digital era, with potential for replication in similar global contexts.
