Abstract

Adsorpsi campuran Remazol Blue dan Indigosol Yellow menggunakan adsorben karbon dari daun bidara arab (Ziziphus spina-christi) telah dilakukan. Remazol Blue dan Indigosol Yellow merupakan pewarna sintetik pada batik. Limbah pewarna, sisa pengolahan batik yang dibuang langsung ke badan air dapat menimbulkan pencemaran, sehingga diperlukan pengolahan terlebih dahulu untuk mengurangi konsentrasinya. Adsorpsi merupakan salah satu metode efektif untuk menurunkan konsentrasi pewarna. Parameter yang digunakan dalam penelitian ini adalah variasi waktu kontak, massa adsorben, konsentrasi awal, konsentrasi awal masing-masing pewarna dan pH larutan. Hasil adsorpsi diukur absorbansinya menggunakan spektrofotometer UV-Vis pada panjang gelombang maksimum masing-masing pewarna. Penelitian dilakukan secara triplo dan uji-t “Paired Two Sample for Means” dengan standar deviasi <2%, diperoleh waktu kontak optimum 45 menit, massa adsorben 45 mg, konsentrasi awal 30 ppm, dan pada pH 3. Berdasarkan hasil penelitian yang telah dilakukan dapat disimpulkan bahwa karbon daun bidara arab merupakan adsorben yang dapat digunakan untuk menurunkan konsentrasi campuran pewarna Remazol blue dan Indigosol yellow yang terkandung dalam limbah pengolahan batik.

Adsorption of Remazol Blue and Indigosol Yellow using bidara arab leaves (Ziziphus spina-christi) as adsorbents has been done. Remazol Blue and Indigosol Yellow are synthetic dyes that used in batik coloring. The batik dye waste can cause pollution thus it is necessary to process the waste to reduce its concentration. Adsorption is one of the effective methods to lower the dyes concentration. The parameters used in this study were in contact time, adsorbent mass, initial concentrations, and pH. Adsorption results are measured using a UV-Vis spectrophotometer at the maximum wavelength of each dye. The research was conducted on a triplo and using t-test "Paired Two Sample for Means" with a standard deviation <2%, the optimum conditions of the adsorption were obtained at 45 minutes contact time, 45 mg adsorbent mass, 30 ppm initial concentration, and at pH 3. Based on the research, it can be concluded that bidara arab leaves is an adsorbent that can lower the concentration of dyes mixture contained in batik waste.
