Abstract
Limbah SBE berasal dari salah satu perusahaan di gresik yang mengandung SiO2, Fe2O3, karbon serta senyawa lainnya. SBE umumnya dibuang ke tempat pembuangan sampah tanpa perawatan khusus sehingga dapat menyebabkan kerusakan lingkungan karena adanya kandungan volatile yang tinggi. Perlu dilakukan pemanfaatan kembali dengan cara meregenerasi SBE teraktivasi sebagai adsorben yang dikompositkan dengan ZnO untuk fotokatalis pada degradasi limbah rhodamine B. Penelitian ini bertujuan untuk menganalisis pengaruh temperatur kalsinasi pada proses aktivasi material SBE terhadap struktur dan morfologi komposit SBE/ZnO serta untuk mendegradasi rhodamine B. Metode yang digunakan untuk aktivasi SBE adalah metode solvent extraction maserasi n-heksana dengan variasi temperatur kalsinasi 400oC, 500oC, dan 600oC. Sedangkan metode yang digunakan untuk sintesis SBE/ZnO adalah metode sol gel. Analisis pengujian pada penelitian ini menggunakan Uji SEM�EDX, XRD, FTIR,BET, XRF, TGA, Fotokatalitik/UV-Vis dan GC�MS. Dari hasil pengujian didapatkan bawha Spent Bleaching Earth berhasil di aktivasi dan di sintesis dengan ZnO dibuktikan dengan bertambahnya luas permukaan BET sebesar 73,366 m2/g dan pore volume pori sebesar 0,0986 cm3/g setelah aktivasi serta struktur ZnO menempel di atas permukaan SBE. Didapatkan pula bahwa degradasi terbaik setelah penyinaran 5 jam pada komposit variasi SBE/ZnO 500 °C dengan persentase degradasi sebesar
56%.

SBE waste comes from a company in Gresik which contains SiO2, Fe2O3, carbon and other compounds. SBE is generally disposed of in landfills without special treatment so that it can cause environmental damage due to its high volatile content. It is necessary to reuse it by regenerating activated SBE as an adsorbent composited with ZnO for photocatalyst in the degradation of rhodamine B waste. This study aims to analyze the effect of calcination temperature on the SBE material activation process on the structure and morphology of the SBE/ZnO composite and to degrade rhodamine B. The method used for SBE activation is n�hexane maceration solvent extraction method with variations in calcination temperature of 400oC, 500oC, and 600oC. While the method used for the synthesis of SBE/ZnO is the sol gel method. Test analysis in this study used SEM-EDX, XRD, FTIR, BET, XRF, TGA, Photocatalytic/UV-Vis and GC-MS tests. From the test results, it was found that Spent Bleaching Earth was successfully activated and synthesized with ZnO as evidenced by the increase in BET surface area of 73,366 m2/g and pore volume of 0,0986 cm3/g after activation and the ZnO structure attached to the surface of the SBE. It was also found that the best degradation after 5 hours of irradiation was on the composite variation of SBE/ZnO 500 °C with a degradation percentage of 56%.
