In this study,Degradation efficiency from pineapple leaves with inoculums was anaerobic digestion.
2 % Sodium hydroxide (NaOH) and Silage were for pretreatment.
The results shows sodium hydroxide concentration affected to degradation efficiency.
First stage and second stage showed high biogas yield and (ml/day). Methane concentration were and %. Degradation efficiency which are TS,VS and COD were 45.92, 53.41, 28.85% and 41.54, 48.50, 63.62 % respectively. Therefore pineapple leaves was high potential of biogas production.
Showed that pretreatment with pineapple leaves sodium hydroxide. Both before and after the fermentation process.
In addition the pretreatment of 2% of sodium hydroxide was increasing efficiency of biogas production.
Also adds to feed the microbes are anaerobic.
And to optimize the production of biogas.
