Abstract

Clean water is defined as water used for daily needs that meets the quality standards set by regulations. To qualify as clean water, it must undergo physical and chemical testing, including metal content analysis. One such metal is manganese, which is regulated with a maximum allowable concentration of 100 µg/L due to its potential to cause chronic toxicity at high levels. This study aimed to determine the concentration of dissolved manganese in clean water samples using the Inductively Coupled Plasma Mass Spectrometry (ICP-MS) method at LPKL Perumda Tirtawening. Method verification was conducted to ensure the reliability and accuracy of the analysis. The results demonstrated excellent linearity (r ≥ 0.995), a detection limit below 100 µg/L, precision with %RSD < 0.5 CV Horwitz, and accuracy with a %recovery of 102.03%. These findings confirm that the ICP-MS method is valid and suitable for manganese testing in clean water at LPKL Perumda Tirtawening.

Abstract

Hydroxyapatite (HAp), a natural mineral form of calcium apatite, has recently received significant attention due to its potential application as a slow-release fertilizer. This review aims to comprehensively analyze HA and its composites, focusing on properties, synthesis methods, and nutrient release mechanisms in agricultural applications. HA's high biocompatibility, excellent adsorption capacity, and ability to release nutrients gradually make it an ideal candidate for increasing soil fertility and crop yields. This review also explores the incorporation of other materials, such as urea, carboxylated cellulose, and montmorillonite, to form HA composites, thereby increasing their efficiency as fertilizer. In addition, the environmental benefits of using HA-based fertilizers, such as reduced nutrient leaching and improved soil health, were also investigated. Challenges and future perspectives are also discussed, emphasizing the need for further research to optimize these materials for practical agricultural use. This review highlights the potential of HA and its composites to revolutionize sustainable agriculture by providing a controlled and efficient nutrient release system.

Abstract

Environmental pollution from dye waste is one of the environmental problems that is of concern today. One method that is effective, reliable, and does not require a large cost is photodegradation. In this study, a TiO2/porous ceramic (TiO2/PC) photocatalyst was used which was synthesized by the sol-gel coating method. The resulting photocatalyst was then characterized using XRF, XRD, SEM, and SAA which were then applied to the photodegradation process of methyl orange (MO) dyestuffs. Optimization of photodegradation conditions of MO dyes using porous TiO2/PC catalysts was carried out using the Response Surface Methodology (RSM) method by Central Composite Design (CCD). The characterization results showed that the TiO2 phase was in the rutile phase with a level of 10.35%. The resulting photocatalyst has pores on the surface covered by TiO2 with a shrinking pore volume after impregnation from 0.076637 cm3/g to 0.064943 cm3/g with an average pore diameter from 4.51187 nm to 4.49999 nm. The optimal condition of degradation of MO dye occurred at pH 6, an initial concentration of 25 mg/L for 120 minutes, with a percentage of degradation of 89.54% and can be used up to four cycles. Thus, TiO2/PC photocatalysts have the potential to be used in the process of processing MO dye waste.

Abstract

Phenol removal through catalytic liquid-phase oxidation using oxygen gas is a green and efficient method. This study reports a systematic investigation of Pt catalysts supported on CeO2–ZrO2–SnO2 (CZSn)/SBA-16, focusing on the effect of SnO2 doping as well as CeO2–ZrO2–SnO2 and Pt loading as a comprehensive strategy to tune catalytic performance under mild conditions. This approach offers a more integrated optimization of catalyst structure and composition, leading to enhanced activity and new mechanistic insights into phenol removal over multicomponent oxide-supported Pt catalysts. XRD and H2-TPR analyses confirmed that 15 mol% Sn (CZSn0.15) provided optimal redox behavior, while higher Sn content led to phase separation. Catalytic tests at 80 °C and atmospheric pressure showed that Pt7CZSn0.1516SBA achieved the highest phenol removal (91%). Increasing CZSn loading up to 16 wt% improved activity, though further increase reduced surface area and performance. Meanwhile, Pt loading was optimal at 7 wt%. Kinetic analysis revealed the reaction followed pseudo-first-order kinetics with a rate constant of 0.39 h-1. The activation energy, derived from Arrhenius plots, was 57.7 kJ·mol-1. These findings demonstrate that optimized CZSn and Pt loadings significantly enhance phenol oxidation under mild conditions, offering a promising route for effective wastewater treatment.

Abstract

This study evaluates the therapeutic potential of bioactive molecules derived from Spirulina platensis such as gallic acid, quercetin, acacetin, and pinocembrin in promoting chronic wound healing using a multiligand in silico approach. This strategy may accelerate drug delivery by efficiently identifying potent candidates. Here, four key protein targets involve in wound healing, transforming growth factor-β (TGF-β), tumor necrosis factor-α (TNF-α), vascular endothelial growth factor receptor 2 (VEGFR2), and Kelch-like ECH-associated protein 1 (KEAP1), were selected based on their pivotal roles in modulating inflammatory responses, tissue proliferation, angiogenesis, and oxidative stress regulation. Molecular docking simulations revealed that the compound combinations of gallic acid–quercetin and acacetin–pinocembrin exhibited the most favorable binding affinities (−13.21 to −15.567 kcal/mol), surpassing the binding energies of native ligands. These combinations demonstrated strong potential to attenuate the overexpression of pro-inflammatory mediators (TGF-β and TNF-α) and to activate the Nrf2 antioxidant pathway through KEAP1 inhibition. Additionally, quercetin and pinocembrin were predicted to modulate VEGFR2-mediated angiogenesis in a controlled manner. Overall, Spirulina-derived bioactive displayed promising synergistic and multitarget interactions that could facilitate and accelerate the wound healing process. These findings provide a rational basis for the development of Spirulina-based topical therapeutics, although subsequent in vitro and in vivo validation is required to substantiate their efficacy

Abstract

Copper (Cu) is an economical alternative electrode material with high electrical conductivity and electrochemical properties that support redox reactions. To enhance its electrochemical performance, the copper electrode was modified using a nanocomposite consisting of 5% chitosan (CS), 5% polysulfone (Psf), 0.9% Zinc Oxide nanoparticles (ZnO Np), and 25% glutaraldehyde (GA). This study aims to characterize and evaluate the electrochemical performance of the CS-GA-ZnO NP/Psf-modified copper electrode using cyclic voltammetry and FTIR spectroscopy. Cyclic voltammetry characterization was carried out using 0.03 M K₃[Fe(CN)₆] and 0.01 M analytical-grade glucose solutions, both prepared in 0.1 M KCl, with scan rate variations of 15–30 mV/s. The optimum scan rate for the K₃[Fe(CN)₆] solution was found to be 20 mV/s with an oxidation-to-reduction current ratio (Ipa/Ipc) of 1.01, while for glucose, the optimum scan rate was 30 mV/s with a ratio of 0.74. The FTIR spectrum showed a peak at 1643 cm⁻¹, indicating successful crosslinking between chitosan and glutaraldehyde through the formation of imine bonds (CH=N). These findings demonstrate that the CS-GA-ZnO NP/Psf nanocomposite effectively enhances electron transfer efficiency on the copper electrode surface. This modified electrode shows strong potential for application in electrochemical sensors, particularly for glucose detection.

Abstract

This study investigates the structural, electronic, and physical properties of X12Y12 (X = B, In, and Y = As, P) fullerene-like cages for NO2 adsorption. We employ Density Functional Theory (DFT) calculations with B3LYP methods, LANL2DZ basis set, and D4 dispersion correction to explore these properties, including ionization potential and electronic affinity linked to HOMO-LUMO gap energy. Moreover, this study explores global reactivity indices such as chemical potential, ionization potential, hardness, and softness. It also examines electronic properties, such as density of states (DOS), natural bond orbital (NBO), and electrostatic potential (ESP), along with chemical interactions like IGMH and AIMD, within the system. The findings demonstrate that the B12As12 nanocage exhibits high sensitivity to NO2 molecules, as evidenced by the bond interaction and adsorption energy of -273.33 kJ/mol, supported by UV-vis and IRI graphics, with the order of systems from the lowest to the highest adsorption energy toward NO2 : B12P12-NO2 < In12As12-NO2 < In12P12-NO2 < B12As12-NO2. AIMD simulations indicate that all nanocages can effectively adsorb NO2 within varying lengths by 1000 fs. This suggests the potential for high NO2 gas adsorption by the B12As12 nanocage. Further investigation is required to assess the potential of other nanocages.

Abstract

Aedes aegypty is the main vector for transmitting the disease (Dangue Hemorrhagic Fever (DHF). The use of larvicide is one method of vector control. In order to reduce the impact of excessive use of synthetic larvicide, it is necessary to develop a natural larvicide by utilizing the n-hexane fraction of cocosan roots (Lansium domesticum Corr var kokosan). The aim of this study was to determine the larvicidal activity and toxicity of the n-hexane fraction of kokosan roots (Lansium domesticum Corr var kokosan) based on the LC50 value with the probit method. There were nine types of treatment including five concentrations of n-hexane fraction of cocosan roots (10; 250; 500; 750; 1000 ppm) as the treatment group, two positive controls (abate and n-hexane pa), and two negative controls (water and water + tween 80). The larvicidal activity test used 15 third instar Aedes aegypti larvae for each test. Meanwhile, the toxicity test used the BSLT method with 15 Artemia salina larvae in the nauplia phase per test. The number of larval deaths was explained by the LC50 value using the probit method. The results of larvacide activity and toxicity tests were 664,02 ppm and 2795,48 ppm, based on LC50. These results indicate that the n-hexane fraction of kokosan roots has moderate activity and is not toxic.

Abstract

Al(III) complex with 1,4-benzenedicarboxylate ligand (Al-BDC) is a porous material that has the potential to be developed as an adsorbent or photocatalyst. This complex is often obtained by the solvothermal method at high temperature. This paper reports the synthesis of Al-BDC complex by solution method at room temperature from two different types of Al(III) salts, namely nitrate salt (complex 1) and chloride salt (complex 2). The synthesis of Al-BDC was conducted with Al(III):H2-BDC mol ratio of 2:3. The synthesized complexes were characterized by ATR-IR, powder XRD, UV Vis–DRS, and DTA–TGA. The results showed that white powders were obtained with a yield of 75.8% (complex 1) and 65.7% (complex 2). The presence of BDC ligands in both complexes was confirmed by the presence of typical absorption bands of C=O, C-O, and Al-O functional groups in their infrared spectra. Both complexes have different surface morphology and average crystallite sizes (28.63 nm – complex 1; 34.98 nm – complex 2), but the powder X-ray diffraction patterns, DTA-TGA thermograms, UV Vis-DRS spectra, and band gap energy values ​​of both complexes are considerably identical. Powder XRD diffraction analysis of both complexes shows a pattern that is identical to the known compound with a formula of {[Al(OH)(BDC)]·(H2BDC)0.69}n(CCDC No. 2179625) in which the compound forms 3D polymeric structure with terephthalic acid occupies the voids.

Abstract

Thermophilic bacteria generally thrive in hot springs and produce thermostable enzymes. These enzymes retain catalytic activity at high temperatures and play an important role in various industrial applications. This study aims to conduct screening, isolation, and characterization of thermophilic amylase-producing bacteria from the Ulubelu hot spring located in Tanggamus Regency, Lampung. Hot spring water samples from a location with a temperature of 60°C and pH 5 yielded eight bacterial isolates with amylolytic activity, as indicated by clear zones around the colonies. Among the isolates obtained, Ulb A3.7 exhibited the largest clear zone diameter and was therefore selected for further characterization. Morphological and physiological analyses revealed that Ulb A3.7 is a Gram-negative rod-shaped bacterium. The Ulb A3.7 isolate tested positive for oxidative-fermentative metabolism, oxidase activity, and glucose utilization. The crude α-amylase from Ulb A3.7 exhibited optimal activity at 80°C and demonstrated a broad activity range. The enzyme was able to retain its amylolytic activity for up to 300 minutes of incubation, indicating its potential for application in high-temperature industrial processes.
