<![CDATA[The increasingly intense competition among micro-enterprises, including in the animal feed store sector, requires business actors to compete not only on price and product quality but also to apply ethical values in serving Muslim consumers, who also consider honesty, fairness, and blessing (barakah) in their transactions. This research is therefore important to conduct because studies on Islamic business ethics have so far been largely centered on formal sectors such as Islamic banking and e-commerce, while its practice in micro-enterprises in the livestock sector remains rarely examined empirically. This research aims to determine the implementation of Islamic business ethics, Muslim consumers' behavior in response to that implementation, and its impact on consumer purchasing behavior at the "Ternak Mandiri" Animal Feed Store in Surodikraman, Ponorogo. This research uses a qualitative approach with a case study design; the researcher acted as the main instrument through a participant-observer position, with data collected through observation, semi-structured interviews, and documentation, then analyzed using an interactive model of data reduction, data display, and conclusion drawing, with validity checked through source and technique triangulation. The results show that the store has implemented the principles of honesty, trustworthiness, fairness, and responsibility in its services, which consumers responded to with trust, satisfaction, and repeat purchases, and which impacted increased trust, loyalty, and consumers' willingness to recommend the store to others—demonstrating that Islamic business ethics plays a strategic role in building long-term relationships between micro-business actors and Muslim consumers]]>
