Abstract

Adsorpsi remasol biru dengan karbon aktif daun bidara arab (Zizphus spina-christi): optimasi menggunakan RSM-CCD telah dilakukan. Remasol biru (RBBR) merupakan pewarna sintetik yang digunakan pada batik di Rumah Batik Putat Jaya. Limbah pewarna batik yang dibuang langsung ke lingkungan tanpa diolah terlebih dahulu dapat mencemari lingkungan serta membahayakan manusia dan organisme hidup di sekitarnya. Adsorpsi merupakan salah satu metode untuk penghilangan pengurangan kadar limbah pewarna dari dalam air. Adsorpsi RBBR dengan adsorben karbon aktif daun bidara arab yang diaktivasi dengan H2SO4, karbon aktif akan dikarakterisasi dengan Fourier transform Infrared (FTIR), Field Emission Scanning Electron Microscopy (FESEM), X-Ray Diffraction (XRD), dan Brunauer-Emmet-Teller (BET). Adsorpsi dilakukan dengan parameter pH (2; 4; 6), waktu kontak (60; 120; 180 menit), dosis adsorben (25; 50; 75 mg), dan konsentrasi awal pewarna (100; 200; 300 ppm). Adsorpsi dilakukan dengan metode batch, kecepatan pengadukan 450 rpm, volume larutan 25 ml, dan 32 variasi desain yang dibuat dengan RSM-CCD. Hasil adsorpsi diukur absorbansinya menggunakan Spektrofotometer UV-Vis pada panjang gelombang maksimum RBBR yaitu 595 nm. Kondisi optimum dicapai pada waktu kontak 180 menit, dosis adsorben 75 mg, konsentrasi 100 mg/L, dan pH 2 dengan %removal mencapai 98,694%, serta kapasitas adsorpsi sebesar 35,67 mg/g.

Remazol Brilliant Blue R. adsorption using activated carbon from bidara arab leaves (ziziphus spina-christi): optimization using rsm-ccd has been done. RBBR is a synthetic dye used in Putat Jaya Batik House. 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. RBBR adsorption with bidara arab leaves carbon activated with H2SO4 as adsorbent. Activated carbon will be characterized using Fourier transform Infrared (FTIR), Field Emission Scanning Electron Microscopy (FESEM), X-Ray Diffraction (XRD), dan Brunauer-Emmet-Teller (BET). Adsorption will be carried out with parameters, pH (2; 4; 6), contact time (60; 120; 180 minutes), adsorbent dose (25; 50; 75 mg), and initial dye concentration (100; 200; 300 ppm). The adsorption will be carried out using the batch method, with stirring speed 450 rpm, volume 25 ml, and 32 design variations that were made using the RSM-CCD. The adsorption results will be measured using a UV-Vis spectrophotometer at the maximum wavelength of RBBR, 595 nm. Optimum conditions were achieved at a contact time of 180 minutes, adsorbent dose of 75 mg, concentration of 100 mg/L, and pH 2 with %removal reaching 98.694%, and adsorption capacity of 35.67 mg/g.
