Abstract

Accumulation of liquid waste of tofu can lead to environmental pollution due to the difficulty decomposition
by microorganisms. Converting liquid waste of tofu into biogas is the right choice to overcome environmental problems
and reduce the usage of fossil fuels. Biogas is produced through the anaerobic digestion (AD) process by
microorganisms. The addition of co-digestion can improve the efficiency of microorganisms. Therefore, this study aims
to compare biogas yields from various types of co-digestion (tomato wastes, food wastes, and cow rumen), determine the
optimal concentration of co-digestion (10%, 20%, and 30%), and measure the content of volatile solids (VS) before and
after the anaerobic digestion process. The methods were the preparation of feedstock, the production of biogas, and
analysis of initial and final VS. The results showed that co-digestion of cow rumen produced the highest biogas yield of
376.24 mL/g VS. Cow rumen of 20% is an optimum co-digestion for biogas production from the liquid waste of tofu. VS reduction is directly proportional to biogas yield.
