Abstract
Limbah Spent Bleaching Earth (SBE) hasil pengolahan minyak sawit mengandung SiO2, Fe2O3, karbon serta senyawa lainnya. Kandungan tersebut menyebabkan SBE dapat dijadikan sebagai adsorben untuk Rhodamine B (RhB). Akan tetapi, adsorpsi dengan SBE kurang efektif. Sehingga dikombinasikan dengan Zinc Oxide (ZnO) menjadi komposit fotokatalis. Oleh karena itu, penelitian ini dilakukan dengan tujuan yaitu menganalisis pengaruh temperatur pirolisis pada proses aktivasi material SBE terhadap (1) struktur dan morfologi komposit SBE/ZnO, (2) kemampuan komposit SBE/ZnO dalam mendegradasi limbah RhB. Metode penelitian ini adalah eksperimental, terdiri atas aktivasi SBE dengan metode pirolisis bervariasi temperatur 400oC (ASBE), 500oC (BSBE) dan 600oC (CSBE) serta sintesis komposit SBE/ZnO dengan metode sol-gel. Kemudian dilakukan pengujian karakterisasi material meliputi uji XRD, FTIR, SEM, BET, dan pengujian fotokatalitik menggunakan spektrfotometri UV Vis dan GC-MS. Hasil menunjukkan bahwa pada temperatur 500oC menghasilkan material SBE mesopori dengan surface area dan pore volume tertinggi yaitu 313,073 m2 .g-1 dan 4,084 cm3 .g-1 serta struktur ZnO menempel di atas permukaan SBE. Kemampuan material komposit SBE/ZnO dengan variasi temperatur 400oC, 500oC dan 600oC dalam degradasi terhadap Rhodamine B setelah penyinaran 5 jam berturut-turut yaitu 13,73%, 52,4% dan 28,79%. Persentase degradasi tertinggi terdapat pada komposit BSBE/ZnO

Spent Bleaching Earth (SBE) is a palm oil processing waste containing SiO2, Fe2O3, carbon and other compounds. It causes SBE to be used as an adsorbent for Rhodamine B (RhB). However, adsorption with SBE is not effective. So, it combined with Zinc Oxide (ZnO) into a photocatalyst composite. Therefore, this research was conducted. The aim of this study was to analyze the effect of pyrolysis temperature on the SBE material activation process on (1) the structure and morphology of the SBE/ZnO composite, (2) the ability of the SBE/ZnO composite in RhB wastewater removal. The method that used is experimental, consists of SBE activation by pyrolysis methods with temperature’s variation 400oC (ASBE), 500oC (BSBE) and 600oC (CSBE), then composite SBE/ZnO’s synthesis with sol-gel method. Material characterization testing includes XRD, FTIR, SEM, BET, and photoalytic testing using UV Vis and GC-MS spectrophotometry. The results showed that at 500oC temperatures produced activated SBE categorized mesopore material with the highest surface area and pore volume of 313,073 m2.g-1 and 4,084 cm3.g-1 and ZnO structure attached on the surface of the SBE. The ability of SBE/ZnO composite materials with temperature variations of 400oC, 500oC and 600oC in degradation against Rhodamine B x after 5 hours of irradiation of 13.73%, 52.4% and 28.79%. The highest percentage of degradation is in the BSBE/ZnO composite.
