PENGARUH PENAMBAHAN KOTORAN SAPI DAN ENCENG GONDOK (EICCHORNIA CRASSIPES) TERHADAP PRODUKSI BIOGAS DARI LIMBAH JEROAN IKAN

Abstract

The purposed of this research to study effect of adding cow dung and water
hyacinth to improve biogas production from fish waste. The method of this
research used experimental method at batch anaerob reactor and absortion carbon
atom used NaOH solution. The result of this research analysis used describtion
method. The observed of parameter included accumulation of biogas production
and also parameter at slurry incuded temperature and pH. Qualitative parameter is
test of flame of biogas. The conclusion value of pH from this research between
control reactor, A1 reactor (fishwaste: cow dung: water hyacinth= 2:9:3), A2
reactor (fishwaste: cow dung: water hyacinth= 1:4:2), A3 reactor (fishwaste: cow
dung: water hyacinth= 1:3:3) is 5 to 10. Temperature range in 28 oC to 31oC. The
result indicated the different composition of subtrat slurry from fishwaste, cow
dung and water hyacinth in scale 2:9:3 (A1 reactor) produced biogas accumulation
and metana the most than the others reactor.
