      Abstract
      Pencemaran zat warna sintetik dari limbah industri tekstil berdampak negatif pada lingkungan sehingga diperlukan metode yang efektif, salah satunya adalah fotodegradasi. Penelitian ini bertujuan menyintesis komposit zeolit alam-TiO2/ZnO/CuO dan menentukan komposisi optimum untuk fotodegradasi rhodamin B. Sintesis dilakukan dengan metode kopresipitasi dan impregnasi menggunakan ragam komposisi 0:100, 50:50, 65:35, 75:25, dan 100:0. Dari karakterisasi XRD terkonfirmasi terbentuknya fase TiO2, ZnO, CuO, dan diduga adanya fase baru Zn2TiO4. Komposisi 75:25 memberikan degradasi tertinggi (63,253%) dan mengikuti kinetika reaksi orde pertama. Hasil ANOVA menunjukkan bahwa ragam komposisi dan penyinaran berpengaruh nyata pada degradasi rhodamin B. Peningkatan fotodegradasi komposit ini terbukti efektif meningkatkan aktivitas fotokatalis sehingga berpotensi kuat sebagai agen pengolah limbah tekstil.
       
      Synthetic dye pollution from textile industry wastewater causes adverse environmental impacts, necessitating effective treatment methods such as photodegradation. This study aimed to synthesize a natural zeolite-supported TiO2/ZnO/CuO composite and to determine the optimum composition for the photodegradation of rhodamine B. The composite was synthesized by coprecipitation and impregnation methods using composition ratios of 0:100, 50:50, 65:35, 75:25, and 100:0. X-ray diffraction (XRD) analysis confirmed the presence of TiO2, ZnO, and CuO phases and indicated the possible formation of Zn2TiO4. The 75:25 composition exhibited the highest degradation efficiency (63.253%), and followed first-order kinetic behavior. ANOVA analysis showed that the catalyst composition and irradiation conditions significantly affected the degradation of rhodamine B. These results demonstrate that the composite effectively enhances photocatalytic activity and has strong potential for textile wastewater treatment applications.
