Abstract

Limbah cair yang disebabkan oleh pewarna merupakan masalah serius bagi lingkungan, sehingga perlu dilakukan pengolahan sebelum dibuang ke lingkungan. Metode adsorpsi dipilih karena mudah dirancang, biaya yang dibutuhkan relatif rendah dan adsorben dapat digunakan kembali. Daun bidara arab (Ziziphus spina-christi) digunakan sebagai prekursor bioadsorben untuk menurunkan konsentrasi dari pewarna. Bio-adsorben dikarakterisasi dengan beberapa instrumen seperti FTIR, SEM-EDX dan XRD. Penelitian ini mengkaji adsorpsi dari dua pewarna batik yaitu Indigosol Pink dan Remazol Yellow dengan variasi waktu kontak (10, 40, 70, 100, 130 dan 160 menit), massa adsorben (40, 50, 60, 70, 80 dan 90 mg), konsentrasi awal larutan pewarna (20, 25, 30, 35 dan 40 ppm) dan pH (2, 4, 6, 8, 10 dan 12) dengan metode batch. Kondisi optimum removal zat warna dalam larutan antara lain waktu kontak 130 menit, massa adsorben 80 mg, konsentrasi larutan awal pewarna campuran 35 ppm, pH 2 dengan kecepatan pengadukan 450 rpm. Hasilnya menunjukkan bahwa persentase removal tertinggi adalah 100% untuk pewarna indigosol pink dan 100% untuk pewarna remazol yellow. Hasil penelitian ini menunjukkan bahwa pewarna batik (Indigosol Pink dan Remazol Yellow) dapat diturunkan konsentrasinya melalui proses yang ramah lingkungan menggunakan bioadsorben murah dari tanaman yaitu bidara arab.

Wastewater caused by dyes is a serious problem for the environment, so it needs to be treated before being discharged into the environment. The adsorption method was chosen because it is easy to design, the required cost is relatively low and the adsorbent can be reused. Bidara arab leaves (Zizippus spina-christi) were used as precursor for the bioadsorbent materials to reduce the concentration of the dye. The bioadsorbent was characterized with using several instrument such as FTIR, SEM-EDX and XRD. This study investigates the adsorption of two batik dyes namely, indigosol pink and remazol yellow at various contact time (10, 40, 70, 100, 130 and 160 min), adsorbent mass (40, 50, 60, 70, 80 and 90 mg), initial dye concentrarions (20, 25, 30, 35 and 40 ppm), and pH (2, 4, 6, 8, 10 and 12) in a batch operation. The optimum conditions for removal of the batik dyes were 130 min contact time, 80 mg adsorbent dosage, 35 ppm nitial dye concentration, pH 2 and agitation speed of 450 rpm. The results indicated that the highest removal persentage was 100% for indigosol pink dye and 100% for remazol yellow dye.The results of this study suggest that batik dye (indigosol pink and remazol yellow) could be reduced the consentration through an enviromentally friendly process using a low cost bioadsorbent from plants i.e. bidara arab.
