Abstract

This study aims to evaluate the effectiveness of Remazol batik wastewater treatment at SMAN 3 Muaro Jambi through degradation and adsorption using a TiO₂/biochar photocatalytic composite. The biochar was derived from cassava peel and employed under UV light irradiation, with UV-Vis spectrophotometry used for analysis. Treatment efficiency was assessed by varying the biochar mass (1–4 grams) and reaction time (1, 3, and 6 hours). The highest removal efficiency of 100% was achieved at 4 grams of biochar and 6 hours of exposure. The adsorption process followed the Freundlich isotherm model, indicating a multilayer adsorption mechanism on the biochar surface. These findings suggest that the TiO₂/biochar composite offers an effective, eco-friendly, and practical solution for small-scale batik wastewater treatment, particularly in educational and home industry settings.

Abstract

Telah dilakukan sintesis dan karakterisasi lapisan tipis ZnO/Ag dengan teknik doctor blade sebagai aplikasi fotokatalis, pendegradasi air Gambut di Kabupaten Tanjung Jabung Timur. Bahan utama dalam pembuatan lapisan tipis adalah Zinc Acetat merck dan AgNO3 sebagai bahan utama Ag. Lapisan tipis di buat dengan variasi doping Ag 0%, 2%, 5%, dan 7%. Sintesis ZnO/Ag menggunakan metode sol-gel dan pembuatan lapisan tipis dengan teknik doctor blade. Hasil karakterisasi UV-Vis menunjukan nilai band gap ZnO/Ag secara berturut-turut yaitu sebesar 3,25 eV, 3,00 eV, 2,65 eV, 2,85 eV. Artinya band gap energy cenderung menurun seiring bertambahnya doping yang diberikan. Hasil analisis data XRD menunjukan ZnO/Ag 0%, 5% dan 7% berbentuk Hexagonal dengan ukuran Kristal berturut-turut sebesar 49,99 nm, 41,66 nm, dan 41,66 nm. Kemampuan degredasi ZnO/Ag terhadap air gambut terbaik ialah ZnO/Ag variasi doping 5% dengan persentasi degredasinya yang dilakukan dibawah lampu UV-Vis sebesar 92,9 % untuk uji parameter TDS, pH 6,7 dan uji parameter TSS 35,5%
