Abstract

Lignocellulose comprises three biopolymers, cellulose, hemicellulose, and lignin that form a complex composite structure. Cellulose, as a biopolymer possesses notable properties including biocompatibility, biodegradability and economic viability. Gunung Kidul, one of the areas in Indonesia, precisely in Yogyakarta, where the population is known to live as cocoa farmers, so the potential for cocoa husks production is quite large. One way to obtain cellulose is by extracting the cacao husks from Gunung Kidul Cocoa Fermentation Center. Cellulose extraction were carried out through two main stages: alkaline delignification and bleaching. Based on the FTIR characterization results, the cocoa skins from Gunung Kidul Fermentation Center have the potential to separate cellulose from lignin and hemicellulose, which is shown in the presence of the function groups O-H, CH2, and C=O. So, the study aimed to get the optimum condition of the cellulose through several variations of the alkaline (NaOH and KOH), and the type of bleaching reagent (NaOCl and H2O2). The concentration of H2O2 (10%, 20%, 30% and 40%). The potential for cellulose can be developed and modified into nanocellulose in the future perspective.

Abstract

Nano zero valent iron (nZVI) has been utilized for environmental remediation and raw water treatment. The NaBH4 reductor, utilized in iron nanoparticle synthesis, yielded easily oxidized and agglomerated material. Using polyphenol as a bioreductor resulted in a more stable material. The purpose of this research is to synthesize and compare quality of nZVI utilizing NaBH4 (C-nZVI) to nZVI utilizing polyphenol from spent tea and the peel of pomegranate (G-nZVI) and determine the efficiency of pomegranate peel G-nZVI in reducing dissolved organic matter. The iron nanoparticle was synthesized by reducing FeCl3 salt in a water solvent. C-nZVI material was generated as a black powder, whereas G-nZVI materials were black flakes. The band gap energy values of these three materials indicate that they have reached the nanoscale. All three materials had entire nZVI unitary groups based on its FTIR spectrums. The X-ray diffractogram did not clearly show the core of the phase crystals. The G-nZVI from the peel of pomegranate had a greater distribution and mean material size than the spent tea G-nZVI. Both zeta potentials G-nZVI demonstrate that the materials were stable in the aqueous medium. After two hours of incubation, G-nZVI pomegranate peel at room temperature and dark conditions achieved an optimal dissolved organic matter breakdown rate of 98%.

Abstract

Vinasse liquid waste is a waste product resulting from the ethanol distillation process. Phosphate in high concentrations can harm the environment, such as by polluting water sources and underground surfaces. In this research, adsorption of phosphate ions was carried out in vinasse waste to remove these pollutants using quaternary ammonium polymers. The study examined the effect of vinasse waste sample temperature on the adsorption of phosphate ions. The first step in this work was to create a quaternary ammonium polymer utilising a one-pot technique using 2-[methacryloyloxy)ethyl trimethylammonium chloride solution, also referred to as META. Subsequently, the adsorption process was performed using temperature variations of 25, 30, 40, 50, and 60 . Phosphate ion adsorbance was measured with UV-Vis spectrometers at a wavelength of 880 nm. The quaternary ammonium polymer succeeded in adsorbing the phosphate ion content of the vinasse waste at an optimal temperature of 40 , with an adsorption capacity of 3.78 mg/L and a removal efficiency of 75.70%.  The adsorption isotherm model for phosphate ions onto quaternary ammonium polymer was studied using the Freundlich and Langmuir equations. The obtained data indicated that the Langmuir isotherm model, with an value of 0.9921, is well-suited for describing the adsorption behaviour in this research.

Abstract

The synthetic dye methylene blue is utilized in many industries. However, it harms the aquatic ecosystem. Methylene blue causes wastewater to become colored. If this colored waste is released into the environment, clean, colorless water will become colored. This work uses a zeolite coal fly ash/TiO2 nanocomposite to enhance the process and identify the photodegradation mechanism of Methylene Blue (MB). Our group has successfully synthesized this nanocomposite using a developed method, improving the materials' capacity for both photodegradation and adsorption. This study has proved nanocomposite performance to degrade methylene blue as a synthetic dye by optimizing the effects of H2O2 addition, catalyst dosage, pH, initial concentration of methylene blue, and irradiation period. The maximum photodegradation in this investigation was observed at a pH of 12 with a nanocomposite dose of 3 g/l and an addition of 8 ml/l of H2O2, and in this study, degradation efficiency reached 100% for an 18 mg/l MB concentration in a short period of 75 minutes. With a reaction rate constant of 0.0601 min-1, the reaction kinetics were described by a pseudo-first-order reaction kinetics model. UPLC-MS/MS QToF analysis revealed the result of chemicals produced by photocatalytic degradation of methylene blue fragmentation into simpler molecules.

Abstract

Exposure to heavy metal ions Pb2+ and Cr3+ in Indonesia is getting more attention, especially in various industries and transportation. The sensor complex compound Dy3+ with fluorescence-based pyrazoline-derived ligands (fluorosensor) has the potential to detect heavy metal ions Pb2+ and Cr2+. This research was initiated by synthesizing the pyrazoline derivative ligand and then reacting it with Dy3+ metal ion.  The formed Dy3+ complex compounds was then characterized using spectroscopic methods. The results of scanning complex compounds using a UV-Vis spectrophotometer obtained two maximum wavelengths namely at 255 and 359 nm are indicating the presence of a transition type n→π* and π→π*. The results of fluorescence spectrophotometer analysis obtained maximum fluorescence intensity of Dy3+ complex compound was in the wavelength at 370 nm with fluorescence intensity of 4273 a.u. Fluorescence based sensor studies of the Dy complex when Pb2+ and Cr3+ metal ions were added showed changes in fluorescence intensity so that the fluorosensor type was obtained for the Dy3+ metal ion complex compound with Pb2+ and Cr3+, namely "turn-on-off" and "turn-off" respectively.

Abstract

Most silica sources are from non-renewable natural sand or rock materials, which affect the element's diminishing availability in the environment. Because bagasse ash has a relatively high silica concentration, it can be used as a silica source to manufacture silica gel. HCl is added during the sol-gel process of silica gel synthesis. The silica gel's characterization employs FTIR, XRD, and SEM instruments. Characterization results showed that silica gel contains silanol groups identified by the appearance of vibrations at the wavenumber of 3383,93 cm-1 and 1635,17 cm-1. Vibrations of the siloxane group appear at the wavenumber of 1020,83 cm-1 and 579,88 cm-1. Silica gel diffractogram showing dilated diffraction peaks at 2q = 22,90ᵒ. Silica gel has potential as an adsorbent in adsorbing methylene blue dye. The ideal parameters for the methylene blue adsorption process are pH 10 and 45 minutes of contact time., silica gel weight of 0.1 g, and methylene blue concentration of 100 mg/L. Using the Langmuir isotherm rule, the silica gel of bagasse ash has a high adsorption capacity of 56.818 mg/g.

Abstract

This article explores the interaction of Coumarin compounds and their derivatives obtained from natural extracts with Carbonic anhydrase II protein in inhibiting Glaucoma computationally. This research method includes modeling using software such as Pymol, Pyrx, Protein Plus, and Lipinski Rule of Five. The results showed Binding Affinity and RMSD of Coumarin, Daphnetin, and Fraxetin compounds with Carbonic anhydrase II with strong interaction. Protein Plus analysis was used to visualize the interaction that occurred between the compound and the Carbonic anhydrase II protein, in addition to the Lipinski Rule of Five test results, which showed results that were in accordance with the rules and met the drug criteria. These results indicate that Coumarin, Daphnetin, and Fraxetin compounds as Carbonic anhydrase II inhibitors have the potential to inhibit glaucoma. Daphnetin compound is the best inhibitor seen from the Binding Affinity value of -6.9, -5.8, and -5.5, as well as the results of Daphnetin's Lipinski Rule of Five data. However, further research is needed to validate this computational study.

Abstract

The aim of this study was to evaluate the potential of brassicasterol found in mustard greens as a cytochrome P450 inhibitor using a computational approach. The research method involved the use of various software such as PyRx, Pymol, Protein Plus, Protein Data Bank (PDB), and Lipinski's rule to analyze the molecular interactions and physicochemical characteristics of brassicasterol. The analysis results showed that brassicasterol has a significant affinity for cytochrome P450, with binding affinity values reaching -8.5, -8.4, and -8.2. RMSD analysis also showed that the brassicasterol-cytochrome P450 complex showed good stability, with RMSD values ranging from 0 to 2.832. The use of Protein Plus software illustrated the interaction between brassicasterol and cytochrome P450, while Lipinski analysis showed that brassicasterol meets the expected physicochemical criteria to be a chagas disease drug candidate, such as a molecular mass of 353, having one hydrogen bond donor and acceptor, and having a log P of 2.2 and a molar reactivity of 99.08. These findings provide new insights into therapeutic development in treating chagas disease using mustard green extract and brassicasterol as a cytochrome P450 inhibitor, but further study is needed to verify the potential of brassicasterol as a chagas disease drug.

Abstract

Betalains are natural pigments that include betacyanin and betaxanthin, found in plants such as beets and cacti. In the food industry, betalains are used as natural colorants due to their color stability and health benefits, including antioxidant and anti-inflammatory properties that support the prevention of degenerative diseases. With increasing demand for natural ingredients, betalains are also being promoted in the cosmetics and health product industries. In the healthy food sector, new extraction techniques like microwave-assisted extraction and aqueous two-phase technology have improved the purification efficiency and quality of betalain pigments. In cosmetics, betalains are utilized as anti-aging and anti-inflammatory components, with innovative approaches like biopolymer encapsulation to enhance product stability. Geographical trends show significant interest in betalain use in natural cosmetics and healthy foods in Europe and Asia, while research in Latin America focuses on its potential as a supplement and food colorant. In renewable energy technology, betalains act as photosensitizers in dye-sensitized solar cells (DSSCs), though their stability still requires optimization, such as through co-sensitization with other pigments. These innovations suggest that betalains hold considerable potential in the food, cosmetics, and energy industries, making them a versatile and globally relevant natural material.
