Abstract

Campuran pewarna Remazol Yellow dan Indigosol Yellow merupakan pewarna sintetik yang digunakan dalam industri batik. Pewarna tersebut berbahaya apabila dibuang secara langsung ke lingkungan tanpa pengolahan lebih lanjut karena bersifat nonbiodegradable dan karsinonegik. Adsorpsi merupakan metode yang efektif untuk menurunkan konsentrasi pewarna Remazol Yellow dan Indigosol Yellow. Adsorben karbon daun Bidara Arab (Ziziphus spina-chiristi) digunakan dalam penelitian ini. Adsorpsi dilakukan dengan metode batch dengan variasi waktu kontak (20; 30; 40; 50; dan 60 menit), massa adsorben (34; 38; 42; 46; 50; dan 54 mg), konsentrasi awal masing-masing pewarna dalam campuran (17,5; 20; 22,5; 25; 27,5; dan 30 mg/L), serta pH (2; 4; 6; 8; 10; dan 12). Hasil adsorpsi diukur absorbansinya dengan Spektrofotometer UV-Vis pada panjang gelombang maksimum masing-masing pewarna yaitu 415 dan 465 nm. Penelitian dilakukan secara triplo dengan standar deviasi <2%. Kondisi optimum adsorpsi diperoleh pada waktu kontak 50 menit, massa adsorben 50 mg, konsentrasi awal masing-masing pewarna dalam campuran sebesar 20 mg/L, dan pada pH 2 dengan perolehan persentase removal masing-masing yaitu 72,09; 72,09; 75,17; dan 96,67% pada Remazol Yellow serta 90,20; 90,20; 95,46; dan 100% pada Indigosol Yellow.

A mixture of Remazol Yellow and Indigosol Yellow dyes is a synthetic dye used in batik industry. These dyes can be harmful if thrown directly into the environment without further processing because they are non-biodegradable and carcinogenic. Adsorption is an effective method to reduce the concentration of Remazol Yellow and Indigosol Yellow mixed dyes. This study was used carbon from bidara arab (Ziziphus spina-chiristi) leaves as adsorbent. Adsorption was carried out by batch method with variations in contact time (20; 30; 40; 50; and 60 minutes), adsorbent mass (34; 38; 42; 46; 50; and 54 mg), initial concentration of each dyes in the mixture (17.5; 20 ; 22.5; 25; 27.5; and 30 mg/L), and pH (2; 4; 6; 8; 10; and 12). The results of the adsorption were measured for its absorbance using a UV-Vis Spectrophotometer at the maximum wavelength of each dyes are 415 and 465 nm. This research was conducted in triplo with a standard deviation of <2%. The optimum adsorption conditions were obtained at a contact time of 50 minutes, adsorbent mass was 50 mg, initial concentration of each dye in the mixture was 20 mg/L, and at pH 2 with the respective removal percentage gains were 72.09; 72.09; 75.17; and 96.67% in Remazol Yellow and 90.20; 90.20; 95.46; and 100% in Indigosol Yellow.
