Daftar Isi:
- Pulp and coffee mucilage are liquid waste from coffee wet processing that have the potential as a raw material producing biogas. The addition of cow manure in an anaerobic fermentation process pulp, coffee mucilage is able to accelerate reaction of biogas forming. Experiment is done to calculate biogas production from liquid coffee waste base to variation of composition pulp, mucilage and addition cow manure. Experiment is done in the labolatory scale, used batch system digester with 5 litre of volume. Pulp coffee substrat (PK) and coffee mucilage (LK) separately and its mixture (PLK) with volume (a) 2,5 litre, (b) 3,0 litre, (c) 3,5 litre and (d) 4,0 litre , each enhanced by 1 kg of cow manure. Each variation is done with three replicates. Production process of biogas percieved by during 30 days. Performance of biogas production percieved to measurement parameter gas concentration of metan (CH4) ratio of karbon-nitrogen (C/N ratio), total of solid (TS), volatile solid (VS), requirement of oxygen (COD), acidity (pH) and teperature. Experiment result showed that the highest of biogas production is mixture variation substrat coffee mucilage 3,5 litre with 1 kg of cow manure (LKc) amounted 72,75 litre/kg TS and CH4 40,19%
