        abstract = {Biogas is a renewable source of energy, playing a vital role in the development of sustainable energy production, waste management, reduction of environmental pollution, and efficient use of resources. In this study, a mini mesophilic anaerobic digester was designed and analyzed in order to determine the influence of pH values and temperature on the production of biogas. Organic food waste was used as the substrate in the experiment, collected from households as waste. The experiment was carried out using a 100-Litre biogas digester, operating in the mesophilic range (30-40°C) for a period of 10 days. The pH values of the substrate were measured on a daily basis, as were the temperatures, while the evaluation of the produced biogas was carried out using a water boiling test, with the heat energy released during combustion calculated using the concept of the change in enthalpy. The findings show that the maximum amount of biogas was produced when the pH values were near neutral, i.e., around 7, with the temperature ranging from 33-34°C. The study shows that the pH values and temperatures have a significant influence on the efficiency of the production of biogas.},
