Abstract

Adsorpsi campuran pewarna sintetik Remazol Brilliant Blue R dan Indigosol Pink IR untuk batik dengan adsorben daun bidara arab (Ziziphus spina-christi) yang telah dikarbonasi telah dilakukan. Pewarna batik apabila langsung dibuang ke saluran air dapat menyebabkan pencemaran lingkungan sehingga harus diolah terlebih dahulu sebelum dibuang untuk mengurangi konsentrasinya. Metode adsorpsi merupakan salah satu metode yang efektif dalam penurunan konsentrasi pewarna batik Remazol Brilliant Blue R dan Indigosol Pink IR. Beberapa parameter yang dipelajari dalam penelitian ini adalah variasi waktu kontak, variasi massa adsorben, variasi konsentrasi awal serta variasi pH larutan. Hasil adsorpsi diukur menggunakan spektrofotometer UV-Vis pada panjang gelombang maksimum masing-masing pewarna. Kondisi optimum adsorpsi dari Remazol Brilliant Blue R, Indigosol Pink IR, dan campuran pewarna diperoleh pada waktu kontak 60 menit, massa adsorben 45 mg, konsentrasi awal 8 ppm, dan pada pH 3. Berdasarkan hasil penelitian dapat disimpulkan bahwa limbah pengolahan batik berupa campuran pewarna Remazol Brilliant Blue R dan Indigosol Pink IR dapat diolah dengan metode adsorpsi menggunakan adsorben daun bidara arab untuk menurunkan konsentrasi campuran pewarna. ====================================================================================================== Adsorption of a mixture synthetic dyes Remazol Brilliant Blue R and Indigosol Pink IR for batik with carbonized bidara arab’s leaf (Ziziphus spina-christi) as adsorbent has been carried out. Batik dyes when directly discharged into waterways, it can cause environmental pollution, so it must be treated before being disposed of to reduce its concentration. The adsorption method is one of the effective methods in reducing the concentration of Remazol Brilliant Blue R and Indigosol Pink IR batik dyes. Some parameters studied in this study are variations in contact time, variations in adsorbent mass, variations in initial concentration and variations in pH of the solution. The adsorption results must be adapted using a UV-Vis spectrophotometer at the maximum wavelength of each dye. The optimum adsorption conditions of Remazol Brilliant Blue R, Indigosol Pink IR, and the dye mixture were obtained at a contact time of 60 minutes, adsorbent mass of 45 mg, initial concentration of 8 ppm, and at pH 3. Based on the results of the study, it can be concluded that batik dye waste in the form of a mixture of Remazol Brilliant Blue R and Indigosol Pink IR dyes can be treated by adsorption method using bidara arab leaf as adsorbent to reduce the concentration of the dye mixture.
