ANALISIS PERENCANAAN REAKTOR BIOGAS KAP 16 M3 DENGAN PEMANFAATAN KOTORAN MANUSIA
ABSTRACT: The effort of
searching about cheaper fuel alternative and environment friendly was solution
for problem in rare fuel. This paper examine potential energy from renewable
source. Design in reactor with 16m3 capacity for retain feces from 200 human.
Based on calculation from the design, this reactor can produce biogas about
4m3/day. Air methane affected by ratio input of C/N (human fecess), time of
residence, pH, temperature, and toxicity. Digester temperature about 25–27oC
and pH 7–7,8 produced biogas with composition of methane air about 77%. For
using this gas we need level of pressure 4 mm H2O and biogas level at 0.23
m3/hour. Beside this if we want for household activities for example cooking we
need biogas 0.30 m3/hour with level pressure at
75 mmH2O. The analysis for effect on environment from mud that produced
from reactor shown decreasing at COD about 90% from new material condition. The comparing of BOD/COD about
0,37 smaller than normal condition from liquid waste that have
BOD/COD=0,5. And the other benefit we get analysis of composition N, P dan K
shown same result that we get at fertilizer.
