Abstract
Indonesia produces over 16 million tons of corn waste annually, much of which remains underutilized. Meanwhile, the ruminant livestock sector contributes up to 15% of total greenhouse gas emissions, primarily methane. FEEDPRO was developed as a functional, low-emission pellet feed for beef cattle, utilizing agricultural residues enriched with Asparagopsis taxiformis and black soldier fly larvae (Hermetia illucens). The formulation combines 35% corn straw, 15% ground corn cob, 25% tofu dregs, 15% dried maggot, and 5% dried Asparagopsis, fermented under solid-state conditions for 14 days. The final pellet contains 23.8% crude protein, 8.2% crude fat, 14.5% crude fiber, and a metabolizable energy value of approximately 2800 kcal/kg. The inclusion of Asparagopsis taxiformis introduces bromoform compounds capable of reducing enteric methane emissions by an estimated 25-30%, while maggot protein enhances feed efficiency and animal productivity. FEEDPRO offers a sustainable, cost-effective, and storable feed alternative that aligns with circular agriculture principles. This innovation has significant implications for climate change mitigation, local agribusiness development, and future research on biofermented, low-emission livestock feed systems.
