PRODUKSI BIOGAS DARI UMBI SINGKONG DENGAN KOTORAN SAPI SEBAGAI STARTER
Abstract: Biogas technology is
easy to be implemented and has a lot of raw materials available in various
forms such aslivestock waste, agricultural waste, industrial waste and the like
which has high organic matter. This study aimedto determine the biogas
production, biogas yield, hydraulic retention time, and the quality of biogas
made fromcassava and cassava leaves with cow dung as a starter. The experiments
were performed using a completelyrandomized design (CRD) with four treatments
and four repetitions. Substrate composition of cassava leaves,cassava tubers,
and cow dung is A (15: 0: 85), B (0:15:85), C (0:25:75), and D (0:35:65).
Variance analysisperformed using SAS statistical program. The results showed
that the composition of the substrate significantlyaffect the total production
of biogas, but did not significantly affect the productivity of biogas. The
highestproduction of biogas obtained from C treatment amounting to 6,995 ml.
The average yield of biogas is 130.85mL/g TVS. Biogas produced from treatment C
and D burn easily and leave a blue flame indicates adequate contentof CH4 in
biogas as a fuel.
