This research aims to study efficiency of bio co-digestion from beverage industry waste (xW) and organic fertilizer raw material (OFM). The researcher was studied suitable mixing ratio between beverage industry wastes were taken from dairy (DW), beer (BW), coffee (CW) and energy drink (EW) industry mixing with OFM. For this study, mixing ratio are 100:0, 75:25, 50:50, 25:75 and 0:100 (ratio by mass of OFM:xW) considered by dry basis and using batch reactor on shaker machine. The experiment result showed the fermented ratio of 75:25 of all industrial wastes seemed to have higher accumulated biogas production compared to other fermented ratios, especially it was found in dairy industry waste, higher more than 2.1 times. The heating values show (at OFM:xW equal 75:25) of OFW with CW equal 2530.92 J > CW equal 1,141.13 J > BW equal 840.48 J > EW 515.79 J, respectively. The proportion OFM:xW at 75:25 show highest gas production and the heating value. The dairy industry waste was suitable for mixing with Organic Fertilizer Raw Material.
