Comparative research of biogas production from EFBMM with semi wet and dry fermentation aims to know the potential of biogas using 20% ​​cow dung solution (inoculum) which is mixed by way of circulation. Semi-wet anaerobic digestion is performed on WC/TS ratio (4.0 - 5.7) and dry digestion is performed on the WC/TS ratio (1.5 - 3.5). Anaerobic fermentation method was developed using a circulation system by observing the physical-chemical characteristics of raw materials and products produced. The results showed that the fermentation of dry and semi-wet fermentation for 65 days decreased the C/N ratio by 5.27% and 19.31%, respectively. Biogas production in semi-wet fermentation produces 18.60 L/kg of EFBMM biogas with CH4 131.85 L/kgVSr gas productivity with biogas composition 40.69% CH4, 49.96% CO2 and 7.58% nitrogen. In dry fermentation, biogas produced 5.98 L/kg EFBMM with CH4 38.71 L/kgVSr gas productivity and biogas composition 35.58% CH4, 46.12% CO2 and 17.31% nitrogen. Semi-wet and dry fermentation process produces carbon (released as biogas) respectively 3.90 kgC (26.88%) and 3.40 kgC (23.44%). The result of lignocellulose analysis showed that dry fermentation of EFB using fungus media was able to degrade 6.00% hemicellulose, 10.60% cellulose and 6.74% lignin. Where as semi-wet fermentation was able to degrade 9.26% hemicellulose, 13.02% cellulose and 9.28% lignin. Imaging results with SEM show the fermentation process alters the EFBMM lignocellulosic morphology structure into more open, hollow and fragile textures. date: 2018-11-09 date_type: published full_text_status: public institution: Poltekkes Tanjungkarang department: Prodi D3 Teknologi Laboratorium Medis thesis_type: diploma thesis_name: other related_url_url: https://iiste.org/Journals/index.php/JEES/article/view/42830 citation: Purnomo, Agus and Suprihatin, Suprihatin and Romli, Muhammad and Hasanudin, Udin (2018) TURNITIN_Comparison of Biogas Production from Oil Palm Empty Fruit Bunches of Post-Mushroom Cultivation Media (EFBMM) from Semi Wet and Dry Fermentation.
