Abstract
Remasol kuning atau Reactive Yellow termasuk dalam jenis zat warna azo yang berbahaya apabila dibuang secara langsung ke lingkungan karena sifat nonbiodegradable, karsinogenik, dan mutagenik yang dimilikinya. Penelitian yang telah dilakukan berhasil menurunkan konsentrasi limbah pewarna batik remasol kuning menggunakan metode adsorpsi dengan adsorben karbon aktif. Beberapa parameter yang digunakan dalam penelitian ialah variasi waktu kontak, dosis adsorben, konsentrasi awal limbah, dan pH larutan. Absorbansi limbah remasol kuning sebelum dan sesudah adsorpsi diukur menggunakan spektrofotometer UV Visible pada panjang gelombang maksimum larutan 420 nm. Hasil penelitian menunjukkan bahwa kondisi optimum adsorpsi diperoleh pada waktu kontak 50 menit, dosis adsorben sebesar 10 mg, konsentrasi awal limbah sebesar 38,763 ppm, serta pH larutan pada kondisi asam (pH 2) dan basa (pH 14). Metode adsorpsi yang digunakan pada penurunan konsentrasi limbah alami pewarna batik remasol kuning menghasilkan persen removal maksimum sebesar 85,288% ± 0,833.

Remazol Yellow or Reactive Yellow is the type of azo dyes which are hazardeous if they are discharged directly into the environment. It is because Remazol Yellow characteristic, i.e. non-biodegradable, carcinogenic and mutagenic. In this study, Remazol Yellow dyestuff removal using adsorption method with activated carbon as adsorbent has been carried out. Contact time, adsorbent dosage, initial waste concentration, and pH of the solution were studied. Absorbances of Remazol Yellow, before and after adsorption, were measured using a UV Visible spectrophotometer at the maximum wavelength (420 nm). The results of this study indicate that the optimum conditions for adsorption were obtained in 50 minutes of contact time, adsorbent dosage of 10 mg, initial waste concentration of 38.763 ppm, and pH of the solution under acidic conditions (pH 2) and alkaline (pH 14). The adsorption method used in concentration decreased of Remazol Yellow dye produced a maximum removal of 85.288% ± 0.833.
