Anis Heryeni is a 54-year-old male farmer with a university-level education and extensive experience in agriculture, spanning 30 years, with the last 10 focused on sheep fattening. His household includes four people, two of whom contribute as family labor. He has completed 24 months of formal agricultural training in agronomy and forestry, and identifies sheep farming as his principal occupation. The farm occupies 135 hectares of rented land, with rainfed cultivation. The infrastructure includes 144 m² of storage and shelter space. Importantly, the farm does not own any agricultural machinery and relies on equipment rented from neighboring farms, which reflects a cost-saving strategy common in semi-intensive systems. Farm operations are entirely managed by Anis himself, who acts as an experienced farmer, without routine support from veterinarians or agricultural engineers. His approach is practical and informed by long-standing personal knowledge and field-based learning.
