| Summary: | The huge amount of coffee pulp waste is an environmental
problem. Anaerobic fermentation is one of the alternative solutions.
However, availability of coffee pulp does not appear for year-round,
whereas biogas needs continuous feedstocks for digester stability. This
research uses coffee pulp from Arabica Coffee Factory at Mengani,
Kintamani, Bali–Indonesia. The coffee pulp was transformed into coffee
pulp-hay product by sun drying for preservations to extend the raw
materials through the year. Characterization of coffee pulp-hay was
conducted after to keep for 15 mo for review the prospect as biogas
feedstocks. Several parameters were analyzed such as C/N ratio, volatile
solids, carbohydrate, protein, fat, lignocellulose content, macro-micro
nutrients, and density. The review results indicated that coffee pulp-hay is
prospective raw material for biogas feedstock. This well-proven
preservation technology was able to fulfill the continuous supply.
Furthermore, some problems were found in the recent preliminary
experiment related to the density and fungi growth in the conventional
laboratory digester. Further investigation was needed to implement the
coffee pulp – hay as biogas feedstocks. |
