Abstract

Medan orange peel (Mopl), which has been modified using cetyltrimethylammonium bromide (CTAB), has the potential to adsorb methyl orange (MO), and thus it can be used as a supporting material for ZnO. The ZnO is a photocatalytic material that is environmentally friendly, inexpensive, non-toxic, and has a wide band gap value. This study aims to determine the effect of calcination temperature on ZnO and ZnO characteristics due to modification using Mopl-CTAB and its effect on the degradation of MO. This research was carried out by synthesizing ZnO and ZnO/Mopl-CTAB materials using impregnation method and varying the calcination temperatures at 150, 250, 350, and 450 °C. The solid material powder obtained was characterized by using Scanning Electron Microscope-Energy Dispersive X-ray (SEM-EDX), Brunauer–Emmett–Teller (BET), Fourier Transform Infra Red (FTIR), X-ray Diffraction (XRD), and Diffuse Reflectance Spectroscopy (DRS). Based on the results of the characterization, greater calcination temperature can affect the characteristics of the photocatalyst, including its morphology, functional groups, crystal structure, crystal lattice, crystallinity, surface area, pore size, pore volume, and energy band gap. The MO photodegradation activity test using the synthesized material was conducted under dark and light conditions. The results of the test revealed that the best or optimum material to be used in degrading MO is a calcined material at 450 °C under light conditions. ZnO material using Mopl-CTAB is better in degrading ZnO/Mopl-CTAB 450 °C than ZnO 450 °C. This study found that ZnO material using Mopl-CTAB  had a percent removal of 78% in 50 min, while ZnO 450 °C only had a percent removal of 53% in 40 min. The reaction kinetics in dark and light conditions follow the pseudo-second-order kinetic model. Copyright © 2023 by Authors, Published by BCREC Group.

Abstract

Photodegradation of organic pollutants depends significantly on the structure of metal oxide-based semiconductor photocatalysts. ZnO/ZSM-5 has shown the potential to significantly improve its photocatalytic efficiency for removing waterborne pollutants. ZnO/ZSM-5 has been reported to be an active catalyst for degrading methylene blue. These methods commonly involve various catalytic reactions, with the Langmuir-Hinshelwood process being used to describe the reaction kinetics. A kinetic study on the photocatalytic degradation of methylene blue using ZnO/ZSM-5 was conducted under UV-LED lamp irradiation. ZnO/ZSM-5 was characterized using XRD, SEM, and N2 adsorption-desorption, and it was prepared via the impregnation method. The interaction between ZnO/ZSM-5 and methylene blue solutions over a period of 30 to 180 minutes was monitored using a UV-Vis spectrophotometer. The photocatalytic degradation of methylene blue followed first-order rate kinetics. The Langmuir-Hinshelwood (L-H) kinetic analysis revealed that the photocatalytic reaction constant (kc) was 4.207 L.mg-1. menit-1, and the Langmuir-Hinshelwood constant (K) was 261.509 L.mg-1.

Abstract

Dye hurts the threat of human health problems and environmental pollution. Microcrystalline cellulose (MCC) based membrane is a good material to be used as an dye separation membrane for having the high hydrophilicity of the membrane. It has been successfully isolated from kapok (ceiba pentandra) with characteristic X-ray diffraction patterns and FTIR absorption peaks, which corresponded to the typical peaks of cellulose. The ultrafiltration membrane was made up of a cellulose acetate matrix created using the phase inversion method. Characterization results indicated that the inclusion of MCC derived from kapok led to a reduction in the contact angle from 65 to 52o, and an increase in membrane porosity from 82 to 85%. In the separation of dye, the composite membrane incorporating MCC filler demonstrated superior performance compared to the membrane lacking MCC, manifesting in an elevated water flux from 43 to 84 L/m².h and methylene blue (MB) rejection from 64 to 99%. The use of MCC as a filler in cellulose acetate membranes can enhance the characteristics and performance of the membrane in MB separation.

Abstract

Kampung Sanan merupakan kampung yang mengelola perternakan sapi, sehingga menghasilkan banuak kotoran Sapi. Untuk memanfaatkan kotoran sapi di Kampung Sanan, kami mengajak warga Kampung Sanan mengembangkan pemanfaatan kotoran sapi menjadi biobriket. Biobriket yang dihasilkan dari kampung Sanan ini telah memenuhi standar SNI dan memiliki kualitas yang layak dengan pengujian sifat fisik dan termal. Selain itu, Program ini berpotensi menjadi aplikasi yang berkelanjutan dalam mendukung energi terbarukan berbasis biomassa, sekaligus memberikan dampak positif bagi pengelolaan limbah dan pemenuhan kebutuhan energi lokal.
