abstract: t.The Empty fruit bunches are one of the palm oil industry wastes, which can be used for
mushroom cultivation. Post-cultivation of mushroom from former EFB-mushroom media
(EFBMM) has the potential to be processed into biogas. The purpose of this research was to
examine optimum co-digestion conditions for biogas production of EFBMM.The research was
carried out in an anaerobic digester with three different conditions - dry fermentation (Water
content (WC)/Total Solid (TS) ratio 1.5 - 3.5), semi-wet fermentation (WC/TS ratio = 4.0 - 5.7)
and wet fermentation (WC/TS ratio> 9.0) conditions. Digester of capacity 50L was used.
Fermentation was done using 20% cow feces as inoculum which then added with circulation
system for 70 days. The results showed that optimum biogas production were produced in semiwet fermentation conditions (WC/TS ratio = 4). It was produced 37.462 liters (2.420 liters CH4/Kg
Volatile Solid (VS)) of biogas with methane contain about 26.231%. Total volume of inoculum
during process was 19.6 liters (1: 4 w/v) with absorbed TS inoculum ratio, TS/I = 0.4 (1:2.5 w/v).
The result of research also showed that biogas which was produced from control about2.865 liters
(0.041 liters CH4/KgVS) , with TS absorbed inoculum ratio, TS/I = 0.5 (1: 5w/v).
