【 摘 要 】

Biohydrogen is one of the promising alternatives to be used as a source of energy in the future. Several studies related to the production of biohydrogen through the process of conversion of organic wastewater by anaerobic process have been done with different reactor conditions. However, biohydrogen is not the main products produced in the process, even biohydrogen is produced in relatively few amounts compared to other acidogenesis products such as volatile acids. The aims of the study are to determine the optimum conditions of biohydrogen production through the control of pH are 5.5; 6.5; 7.5 and 8.5. This factor affects to the metabolism pathway. The study was conducted using the wastewater from the palm oil mill effluent as a substrate, pure culture and mixed culture bacteria as a biomass and performed in the laboratory using an anaerobic batch reactor which will be operated for 72 hours. Sampling was done every 6 hours and then analysed the product of acidogenesis produced. The results show that the optimum conditions for biohydrogen production occurs in the reactor with the pH 5.5-6.5 are 15.27% ± 0.404% to 15.40% ± 0.265%.
