| Abstrak (Bhs. Indonesia) | Material polianilin dalam bentuk garam emeraldin berhasil disintesis dengan menggunakan metode polimerisasi antarmuka. Material polianilin dikompositkan dengan penambahan ZnO sebanyak 0, 1, 5, 10 % (b/b). Polianilin/ZnO nanokomposit terbukti dapat menurunkan konsentrasi congo red lebih baik dibandingkan polianilin. Material dikarakterisasi menggunakan SEM (Scanning Electron Microscopy), EDX (Energy Dispersive XRay Spectroscopy), dan FTIR (Fourier Transform Infra-Red). Material polianilin/ZnO 5% memberikan kondisi optimum dalam menurunkan konsentrasi congo red melalui dua mekanisme proses, yaitu proses adsorpsi dan fotokatalisis. Pada suasana pH 7 dengan waktu kontak selama 60 menit serta di bawah kondisi penyinaran UV, material polianilin/ZnO 5% memberikan kondisi optimum dalam menurunkan konsentrasi congo red 100 ppm dengan persen penurunan sebesar 94,39%. Laju kinetika penurunan konsentrasi congo red polianilin/ZnO berjalan mengikuti persamaan laju kinetika orde satu dengan konstanta laju fotodegradasi congo red tertinggi ditunjukkan oleh polianilin/ZnO 5% sebesar 0,112929 menit-1. Stabilitas polianilin/ZnO dengan 3 kali pengulangan memberikan persen penurunan konsentrasi congo red 25 ppm sebesar 6%. Regenerasi polianilin/ZnO menggunakan HCl terbukti dapat mengaktifkan kembali polianilin/ZnO dalam menurunkan konsentraasi congo red. |

| Abtrak (Bhs. Inggris) | Polyaniline material in the form of emeraldin salt was successfully synthesized using the interface polymerization method. Polyaniline material is composited by adding ZnO as much as 0, 1, 5, 10% (w/w). Polyaniline/ZnO nanocomposite has been shown to reduce congo red concentration better than polyaniline. The material is characterized using SEM (Scanning Electron Microscopy), EDX (Energy Dispersive X-Ray Spectroscopy), and FTIR (Fourier Transform Infra-Red). Polyaniline/ZnO 5% provides optimum conditions in reducing the concentration of congo red through two process mechanisms, namely the adsorption process and photocatalysis. At a pH 7 with a contact time of 60 minutes and under UV irradiation conditions, polyaniline/ZnO 5% provides optimum conditions in reducing the concentration of 100 ppm congo red with a percent decrease of 94.39%. The kinetic rate of the decrease in polyaniline/ZnO congo red concentrations proceeded following the first order kinetic equations with the highest congo red photodegradation rate constants shown by polyaniline/ZnO 5% at 0.112929 minutes-1. The stability of polyaniline/ZnO with 3 repetitions gave a 6% decrease in the concentration of congo red 25 ppm. Polyaniline/ZnO regeneration using HCl is proven to be able to reactivate polyaniline/ZnO in reducing congo red concentration. |
