The underutilization of pesantren food waste, despite its abundance and rich organic composition, contributes to environmental pollution and potential pathogen spread.This study hypothesized that fermentation of pesantren food waste using Rhizopus oligosporus, supplemented with various carbon sources, could enhance its nutritional value and suitability as an alternative poultry feed. A solid-state fermentation process was conducted for five days at 30–37°C under aerobic conditions, using four treatments: A (90% pesantren food waste [PFW] + 10% expired noodles), B (90% PFW + 10% expired bread), C (90% PFW + 10% rice bran), and D (90% PFW + 10% cassava dreg), with five replications per treatment. Nutritional composition was analyzed through proximate and mineral content tests, while statistical analysis was performed using one-way ANOVA followed by Duncan’s Multiple Range Test (DMRT) at P<0.05. The results showed that carbon source supplementation had a highly significant effect (P<0.05) on moisture, dry matter, crude fat, crude protein, crude fiber, and gross energy, though no significant changes were observed in ash, calcium, or phosphorus levels. Among all treatments, cassava dreg (Treatment D) produced the most nutritionally enhanced fermented product, indicating its potential as a sustainable and cost-effective poultry feed component. © 2025 Kumar et al. and 2025 by the authors.
