Abstract
Indigosol Pink IR merupakan salah satu zat warna sintetik batik yang dapat mencemari ekosistem perairan tanpa pengolahan lebih lanjut. Untuk itu perlu dilakukan upaya penurunan konsentrasi zat warna sintetik Indigosol Pink IR sebelum dibuang dengan metode efektif yaitu adsorpsi menggunakan karbon aktif. Penentuan kondisi optimum adsorpsi larutan Indigosol Pink IR dilakukan dengan empat parameter, yaitu waktu kontak (5; 10; 15; 20; 25; 30; 35; 40; 45; 50; 60 menit), dosis adsroben (2,50; 5,00; 7,50; 10,00; 15,00; 17,50; 20,00; 22,50 mg), konsentransi awal (20; 30; 40; 50; 60; 80; 100 ppm), dan pH awal (2; 3; 4; 5; 6; 7; 9; 11; 12). Dari hasil penelitian yang dilakukan triplo dan uji-t “Paired Two Sample for Means” dengan relatif standar deviasi <2% didapatkan waktu kontak optimum 35 menit dan dosis adsorben 10 mg (removal 88,82% + 1,49%), konsentrasi awal 80 ppm (removal 89,47% + 0,22%), dan pH awal 3 (removal 95,87% + 0,25%). Metode adsorpsi optimum yang digunakan menghasilkan removal sebesar 95,87% + 0,25%. Proses adsorpsi melibatkan proses adsorbsi fisik dengan model isoterm Freundlich.

Indigosol Pink IR is one of batik's synthetic dyes which can pollute the aquatic ecosystem without further processing. For this reason, it is necessary to reduce the concentration of Indigosol Pink IR synthetic dyes before being discharged by an effective method of adsorption using activated carbon. Determination of the optimum adsorption of the Indigosol Pink IR solution was carried out with four parameters, is the contact time (5; 10; 15; 20; 25; 30; 35; 40; 45; 50; 60 minutes), the dose of adsrobents (2.50; 5.00; 7.50; 10.00; 15.00; 17.50; 20.00; 22.50 mg), initial concentrations (20; 30; 40; 50; 60; 80; 100 ppm), and initial pH (2; 3; 4; 5; 6 ; 7; 9; 11; 12). From the results of the research carried triplo and t-test "Paired Two Sample for Means" with deviation <2%, the optimum contact time was 35 minutes and the dose of adsorbent was 10 mg (removal 88.82% + 1.49%), initial concentration was 80ppm (removal 89.47% + 0.22%), and initial pH 3 (removal 95.87% + 0.25%). The optimum adsorption method used produces %removal of 95.87% + 0.25%. The adsorption involves the physical adsorption process with the Freundlich isotherm model.
