SCREENING THE EFFECTS OF THE ADDITION OF FE2O3, ZNO, AND MNO METAL OXIDES ON ETHANOL FORMATION IN ANEROBIC PROCESS OF PALM OIL MILL EFFLUENT (POME)
The palm oil extraction process generates liquid waste as an organic residue known as Palm Oil Mill Effluent (POME), which has the potential to pollute the environment if not properly treated.

| Summary: | The palm oil extraction process generates liquid waste as an organic residue known as Palm Oil Mill Effluent (POME), which has the potential to pollute the environment if not properly treated. Anaerobic treatment of POME has the potential to produce bioethanol, which is beneficial as an alternative fuel. This study examines the effect of three metal oxide cofactors (Fe2O3, ZnO, and MnO) on ethanol production in the anaerobic treatment of artificial POME, replicating palm oil waste from PT Condong Garut. Additionally, the study evaluates the impact of these cofactors on the formation of volatile fatty acids. The analysis also includes parameters such as COD, ethanol, TAV, VSS, and pH, which influence the anaerobic biological process in bioethanol production from POME. The research stages began with seeding, acclimatization, and reactor operation. The results showed that the acidogenesis products formed within 24 hours were still dominated by other acidogenesis products, such as non-volatile acids and gases like CO2 and H2. The addition of Fe2O3 as a trace element shifted the direction of acidogenesis product formation towards the largest ethanol production, reaching 3792.35 mgCOD/L at the 24th hour, with a Degree of Ethanofication value of -0.271, and a product percentage of 36.64% in the mass balance |
