a complex compound which is difficult to be described, so it can slow the rate of
biogas formation. To facilitate the disintegration of compound cellulose into
simple sugars that can be utilized in the biogas formation, it is necessary to pretreatment
toward water hyacinth. One of the pretreatment to do is using acid
hydrolysis. This research aims to study the effect of concentration of H2SO4
addition as a catalyst in the hydrolysis process and the length of time the
hydrolysis toward the cellulose degradation and glucose formation. In addition,
this research also studies the effect of pretreatment on water hyacinth toward
increasing of biogas production with the addition of active sludge biodigester as
biostarter.
This research is conducted in two stages, the first stage is the hydrolysis
process with variation concentration of H2SO4 96% addition as much as 0%, 1%,
2%, 3%, 4% and 5% (v/v) reacted in an autoclave at a temperature of 121 oC and
permanent pressure 2.0 atm for 60 minutes. Further ,it is done hydrolysis with
time variation, i.e.: 0 minutes, 30 minutes, 45 minutes, 60 minutes, 75 minutes and
90 minutes. The second stage is the fermentation process slurry of water hyacinth.
The hydrolysis results are added by an active sludge biodigesteras biostarter. The
fermentation process is done by batch scheme in biodigester as a form of
erlenmeyer 1000 ml.
The results of this research show that the highest efficiency of cellulose
degradation obtained 65.5% by the addition of 96% H2SO4 concentration of 5%.
In this stage of hydrolysis with time variation, the highest efficiency of cellulose
degradation is resulted in 90 minutes of 79.1%. However, the increase of highest
glucose content is at 45 minutes of 9.2% from the initial glucose content. Biogas
production from water hyacinth that has been pretreatment added the active
sludge biodigester increases of 2.5 times of the material without pretreatment.
The highest accumulation of biogas obtained at B7 biodigester for 450.4 mL by
the addition of 96% H2SO4 concentration of 5% within 90 days and the result of
methane content is 69.8% measurements on day-88.</description><publisher>[Yogyakarta] : Universitas Gadjah Mada</publisher><date>2013</date><type>Thesis:Thesis</type><type>PeerReview:NonPeerReviewed</type><identifier> , RAUDATI HILDAYATI and , Dr. Ir.
