Abstract

Industri minyak kelapa sawit menghasilkan limbah signifikan seperti POME yang dapat mencemari lingkungan jika tidak dikelola dengan baik. POME dapat merusak lingkungan terutama ekosistem perairan. Pengolahan POME penting untuk keberlanjutan industri ini. Advanced Oxidation Processes (AOPs), termasuk fotokatalitik, merupakan salah satu opsi teknologi yang dikembangkan untuk mendegradasi senyawa organik dalam limbah POME. Dalam studi ini, degradasi fotokatalitik limbah POME menggunakan katalis berbasis WO3 dengan menggunakan lampu Xenon 500 W menunjukkan bahwa metode ini efektif dalam mengurai limbah POME. Fotokatalis WO3 disintesis menggunakan metode hidrotermal pada temperatur 180, 200, 220, dan 240 °C, menghasilkan struktur kristal Hexagonal dan Orthorhombic, danTipe V mesopori. Penggunaan katalis WO3 dengan konsentrasi 1 g/L mampu mengurangi Chemical Oxygen Demand (COD) hingga 48,05%, degradasi warna hingga 36,22%, dengan konstanta laju reaksi COD  sebesar 3,7×10-3 menit-1.

Abstract

Indonesia is among the world’s largest palm oil market countries leading to significant growth in the domestic palm oil industry. However, the increase in palm oil trading has also led to a rise in the production of waste known as Palm Oil Mill Effluent (POME). Currently, the majority of factories use open ponds for POME processing, but this method is considered ineffective for treating POME. To address this issue, researchers are exploring photocatalytic technology, which utilizes light energy (UV, visible, sunlight) to produce radical compounds that act as oxidizing agents for POME degradation. In this study, ZnO was employed as a catalyst. The XRD and UV-vis DRS characterizations confirmed that ZnO had a hexagonal wurtzite crystal structure with a band gap energy of 3,22 eV. The photocatalytic activity test results revealed that using 0.5 g/L ZnO catalyst proved to be efficient in degrading organic content in POME. The percentage of chemical oxygen demand (COD) degradation reached 22.85%, color degradation reached 48.53% and the reaction rate kinetics constant of COD degradation was at 2.6´10-3 min-1.
