Abstract

Limbah pewarna sintetis Rhodamine-B (RhB) dari industri tekstil merupakan polutan serius yang berpotensi menyebabkan iritasi kulit dan dampak lingkungan. Dalam upaya mitigasi, penelitian ini mengembangkan komposit Bi2O3/Zeolite/Carbon Sphere (CS) melalui sintesis hidrotermal. Pemanfaatan limbah air tuak, yang sering terbuang akibat kandungan alkoholnya, menjadi fokus utama. Air tuak diubah menjadi carbon spheres yang memiliki luas permukaan besar, sehingga efektif dalam membantu Bi2O3 mendegradasi RhB. Untuk meningkatkan efektivitas carbon spheres dalam degradasi, material ini dikompositkan dengan Bi2O3 dan Zeolit. Bi2O3 berperan sebagai fotokatalis, dengan band gap 3.3-3.8 eV yang memungkinkannya menyerap cahaya tampak dan menghasilkan pasangan elektron-lubang (hole) untuk mendegradasi polutan. Sementara itu, zeolit dengan struktur pori-pori unik dan porositas tinggi sangat efisien dalam menyerap berbagai kontaminan bermuatan seperti zat warna, amonia, dan logam berat, melalui kapasitas pertukaran kationnya. Penelitian ini bertujuan untuk mensintesis komposit Bi2O3/Zeolite/Carbon Sphere dengan memvariasikan penambahan massa zeolit sebesar 1 g, 1.2 g, dan 1.4 g. Metode hidrotermal digunakan untuk sintesis carbon spheres maupun komposit Bi2O3/Zeolite-13X. Karakterisasi material dilakukan menggunakan SEM-EDX, XRD, dan FTIR. Adapun pengujian performa fotokatalisis dilakukan melalui uji fotokatalisis dan UV-VIS. Hasil menunjukkan bahwa komposit Bi2O3/Zeolite/Carbon Sphere dengan penambahan massa zeolit 1.2 g memberikan hasil paling optimum, mampu mendegradasi limbah RhB hingga 73.52% dalam waktu dua jam.

Synthetic dye waste Rhodamine-B (RhB) from the textile industry is a serious pollutant with potential to cause skin irritation and environmental impact. In an effort to mitigate this problem, this research developed a Bi2O3/Zeolite/Carbon Sphere (CS) composite synthesized through a hydrothermal process. The utilization of waste tuak water, often discarded due to its alcohol content, became a main focus. Tuak water was converted into carbon spheres with a large surface area, making them effective in assisting Bi2O3 to degrade RhB. To enhance the effectiveness of carbon spheres in degradation, this material was composited with Bi2O3 and Zeolite. Bi2O3 acts as a photocatalyst, with a band gap of 3.3-3.8 eV enabling it to absorb visible light and generate electron-hole pairs for pollutant degradation. Meanwhile, zeolite with its unique porous structure and high porosity is very efficient in adsorbing various charged contaminants such as dyes, ammonia, and heavy metals, through its cation exchange capacity. This study synthesized a Bi2O3/Zeolite/Carbon Sphere composite by varying the addition of zeolite mass at 1 g, 1.2 g, and 1.4 g. The hydrothermal method was used for the synthesis of both carbon spheres and the Bi2O3/Zeolite-13X composite. Material characterization was performed using SEM-EDX, XRD, and FTIR. Photocatalytic performance testing was conducted through photocatalysis and UV-VIS tests. The results showed that the Bi2O3/Zeolite/Carbon Sphere composite with 1.2 g zeolite addition yielded the most optimum results, capable of degrading RhB waste up to 73.52% within two hours.
