Abstract

Palm oil plays a vital role in Indonesia's economy, with production reaching 45.58 million tons in 2022. However, the increase in palm oil production also leads to the generation of palm oil mill effluent (POME), which poses a potential environmental threat. POME contains high levels of chemical oxygen demand (COD), making its treatment crucial. Photocatalytic technology using zinc oxide (ZnO), produced through biosynthesis, offers a promising solution. This study aims to assess the impact of irradiation time and optimal ZnO weight on the reduction of COD levels in POME. The research involved varying the irradiation time between 15–75 min with a ZnO weight of 120 mg, alongside different plant-based photocatalysts, such as yellow pumpkin seeds, papaya leaves, and pineapple peels. The best results for POME photodegradation were achieved using ZnO derived from yellow pumpkin seeds, which resulted in a COD reduction to 469 mg/l after 75 min of irradiation.
