The optimal solution to this goal is purifying used dialysate fluid, which allows a reduction in the volume of water used during hemodialysis.<\/p>\n<p><\/p>\n<p data-start=\"596\" data-end=\"1119\">Polymer membranes are one alternative method to regenerate used dialysate. Cellulose acetate membranes are one of the polymers widely studied because they are hydrophilic and possess superior characteristics such as good fouling resistance, moderate flux, and good biocompatibility. Cellulose acetate membranes have been extensively used by researchers for dialysate regeneration due to their hydrophilicity. Therefore, in this study, cellulose acetate polymer membranes were used for creatinine removal in dialysate fluid.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7377ed9 elementor-widget elementor-widget-image\" data-id=\"7377ed9\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"512\" height=\"384\" src=\"https:\/\/mkimia.fst.unair.ac.id\/wp-content\/uploads\/sites\/27\/2025\/04\/pemenang-2.jpg\" class=\"attachment-full size-full wp-image-5224\" alt=\"\" srcset=\"https:\/\/mkimia.fst.unair.ac.id\/wp-content\/uploads\/sites\/27\/2025\/04\/pemenang-2.jpg 512w, https:\/\/mkimia.fst.unair.ac.id\/wp-content\/uploads\/sites\/27\/2025\/04\/pemenang-2-300x225.jpg 300w\" sizes=\"(max-width: 512px) 100vw, 512px\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">Gayatri received the 2nd place certificate from the Master\u2019s program coordinator.<\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f09407f elementor-widget elementor-widget-text-editor\" data-id=\"f09407f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p data-start=\"51\" data-end=\"684\">The 2nd place was awarded to Gayatri Budhi Khrisnamurti (Gayatri) for her research titled <em data-start=\"141\" data-end=\"323\">\u201cEffect of Substituents on Benzoquinone Derivatives as Electron Acceptors in the Dehydrogenation Reaction Catalyzed by 3-Ketosteroid-\u03941-Dehydrogenase from Thermomonospora curvata.\u201d<\/em> Gayatri explained that sterols are a type of lipid with a cyclopentanoperhydrophenanthrene structure that functions to maintain cell membrane stability and serves as a precursor in the synthesis of steroid hormones and vitamin D. Microorganisms can convert natural sterols such as cholesterol and phytosterols into steroid drug precursors through biocatalysis.<\/p>\n<p><\/p>\n<p data-start=\"686\" data-end=\"900\">The enzyme 3-ketosteroid-\u03941-dehydrogenase (\u03941-KSTD) plays a role in the 1,2-dehydrogenation reaction of 3-ketosteroids, which is crucial in the production of anti-inflammatory drugs such as cortisol and prednisone.<\/p>\n<p><\/p>\n<p data-start=\"902\" data-end=\"1513\"><em data-start=\"902\" data-end=\"927\">Thermomonospora curvata<\/em>, a thermophilic bacterium from the Actinobacteria phylum, produces \u03941-KSTD (Tcu-\u03941-KSTD) that has high potential in steroid biotransformation at an optimal temperature of 50\u201360\u00b0C. The natural electron acceptor for \u03941-KSTD has not been identified, but several benzoquinone derivatives, such as chloranil, can serve as alternatives.

Chloramphenicol is commonly used due to its low cost and high stability; however, its residues in the environment can lead to bacterial resistance and pose risks to human health and the economy, such as export bans on shrimp due to chloramphenicol residues.<\/p>\n<p><\/p>\n<p data-start=\"768\" data-end=\"948\">Various methods have been developed to remove chloramphenicol from the environment, such as adsorption using composites, MOFs, and carbon-based materials, but each has limitations.<\/p>\n<p><\/p>\n<p data-start=\"950\" data-end=\"1566\">A promising approach is the use of photocatalytic membranes, especially Mixed Matrix Membranes (MMM) based on polyethersulfone (PES) modified with photocatalytic materials like CuFe\u2082O\u2084. CuFe\u2082O\u2084 ferrite is chosen for its stability, affordability, environmental friendliness, and its ability to enhance membrane performance in degrading chloramphenicol and reducing fouling.
