Abstract

This article attempts to identify factors affecting participation in payment of irrigation service fees. There are five variables comprising demographic and economic of land variables were tested to find the variables that influenced the participation significantly. The five variables tested consisted of age and formal education as demographic variables; land productivity, land size, and land tenure as the economic of land variables. The results showed that formal education (demographic variable) had positive relationship and land size (economic of land variable) had negative relationship with the participation. Positive relationship between formal education and participation in payment of irrigation service fees meant that the participation increased as farmers’ education increased. Meanwhile, negative relationship between land size and the participation in payment of irrigation service fees showed that the farmers’ participation would increase as the land size owned by farmers decreased. In other words, participation in payment of irrigation service fees was higher among farmers with small lands rather than that among farmers with large lands.

Abstract

The increasing volume of corn cob waste in Indonesia poses environmental challenges and reflects underutilized biomass with potential economic value. This study examines the conversion of corn cobs into Bio-CNG through anaerobic digestion and the utilization of fermentation residues as livestock feed within a circular economy framework. The novelty lies in integrating energy production, feed generation, and circular system marketing in a single agro-based model. A laboratory experimental study using a 3×3 factorial Completely Randomized Design (CRD) was conducted, employing Biomethane Potential Tests (BMP) with rumen and methanogenic inoculums at different temperatures and fermentation times (2–6 days). Gas production and digestate composition were analyzed using standard methods, including proximate analysis. Results show substrate degradation up to 55.34%, methane production reaching 3.82% (rumen microbes, 39°C) and 10.79% (methanogenic basis), and total gas production up to 10.29%. Digestate quality improved, with protein increasing from 4.95% to 7.39% and TDN from 53.34% to 55.42%, indicating suitability as ruminant feed. The study is limited to laboratory-scale and short fermentation duration. Practically, this model can support integrated agroenergy systems in rural areas. In conclusion, corn cobs offer significant potential as a dual resource for renewable energy and livestock feed, supporting sustainable circular agriculture.
