PENGARUH WAKTU FERMENTASI DAN KOMPOSISI LIMBAH ECENG GONDOK (Eichhornia crassipes) UNTUK MENGHASILKAN GAS BIO DENGAN METODE HIDROLISA BASA MENGGUNAKAN NATRIUM HIDROKSIDA (NaOH)
Abstract: Water hyacinth
(Eichhornia crassipes) is a plant that become aquatic waste and its existence
has not yet widelyused. The content of cellulose, hemicellulose, and lignin
inside it can be used into biogas through fermentation process.The purpose of
this research was to determine the effect of alkali pretreatment methods on the
yield biogas volume and Total Suspended Solid (TSS) revomal percentage. The
study was did by fermentation process the water hyacinth with NaOH
concentration of 2,86; 3;4; and 6,67 (M) with water in ratio hyacinth:water
70:30; 50:50; 30:70 and 100:0 (v/v) mixed
with cow dug starter in an anaerobic digester batch system of 2,5 L capacity.
In this study the highest biogas production at NaOH concentration 6,67 M was in
ratio of 70:30 (v/v) with yield biogas volume 506 mL and TSS revomal percentage
of 93,23%. Minimum value of gasbio production concentration of NaOH 3M
withwater hyacinth:water ratio 30:70 (v/v) generate yield biogas volume 158 mL
and TSS revomal percentage of 81,48%.
