Abstract
Air limbah merupakan salah satu masalah besar terhadap lingkungan. Salah satu parameter yang sulit untuk ditangani adalah zat warna. Zat warna dalam air limbah sulit ditangani karena mengandung material organik yang sulit terdegradasi. Selain itu, timbunan spent bleaching earth (SBE) menjadi masalah tersendiri, SBE terproduksi 2-3 ton/harinya. Namun, SBE ternyata memiliki potensi untuk menyerap zat warna. SBE/ZnO merupakan material komposit yang dapat menyerap, sekaligus mendegradasi zat warna. SBE/ZnO dipersiapkan dengan proses maserasi dan penambaha solgel. Dengan material ini, alternatif pengolahan adsorpsi disertai dengan advanced oxidation process (AOPs) dilakukan dengan tujuan menyerap zat warna yang dari air limbah tekstil, sekaligus mendegradasi zat warna dari bentuknya yang sulit terdegradasi. Penelitian dilakukan menggunakan reaktor AOPs dengan Ozon dan UV, dengan variasi massa adsorben SBE/ZnO dan konsentrasi larutan zat warna. Dengan masa aktif reaktor 1 jam, mekanisme penyerapan dan degradasi dari SBE/ZnO terhadap larutan akan terlihat per jamnya. Hasil pengolahan sendiri akan diukur dengan spektrofotometer, serta pengukuran parameter air limbah lainnya yaitu warna dan COD guna mengetahui kemampuan SBE/ZnO dalam menyerap dan mendegradasi zat warna. Proses adsorpsi yang dihasilkan SBE/ZnO berada pada 11,79 mg/gr dan degradasi SBE/ZnO dala proses AOPs dapat mencapai efisiensi pengolahan sebesar 90% dalam 24 menit. Pengaruh massa adsorben dan konsentrasi larutan dalam proses tidak signfikan, memiliki peranan dalam laju degradasi dan penurunan nilai COD

Waste water is one of the big problems for the environment. One of the parameters that is difficult to handle is the dye. Dyes in wastewater are difficult to handle because they contain organic materials that are difficult to degrade. In addition, spent bleaching earth (SBE) deposits are a separate problem, SBE is produced 2-3 tons/day. However, SBE apparently has the potential to absorb dyes. SBE/ZnO is a composite material that can absorb and degrade dyes. SBE/ZnO was prepared by maceration process and addition of solgel. With this material, an alternative adsorption treatment accompanied by an advanced oxidation process (AOPs) is carried out with the aim of absorbing dyes from textile waste water, as well as degrading dyes from forms that are difficult to degrade. The research was carried out using an AOPs reactor with Ozone and UV, with variations in the mass of the SBE/ZnO adsorbent and the concentration of the dye solution. With an active reactor period of 1 hour, the absorption and degradation mechanism of SBE/ZnO in solution will be seen hourly. The results of the processing itself will be measured with a spectrophotometer, as well as measurements of other wastewater parameters, namely color and COD to determine the ability of SBE/ZnO to absorb and degrade dyes. The adsorption process produced by SBE/ZnO is at 11.79 mg/gr and the degradation of SBE/ZnO in the AOPs process can reach a processing efficiency of 90% in 24 minutes. The effect of adsorbent mass and solution concentration in the process is not significant, has a role in the rate of degradation and decrease in COD value
