“…Utilized as indicators in environmental assays, AgNPs are employed to evaluate their impact on ecosystems. Studies utilize various biological indicators to comprehend how AgNPs may affect aquatic and terrestrial environments, thereby assisting in the management of potential ecological risks 77 . Research examining the influence of AgNPs on plant growth parameters suggests potential agricultural applications.…”

This research explores the eco-friendly synthesis of silver nanoparticles (AgNPs) using Cassia occidentalis L. seed extract. Various analytical techniques, including UV–visible spectroscopy, transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), and energy dispersive X-ray spectroscopy (EDX), were employed for comprehensive characterization. The UV–visible spectra revealed a distinct peak at 425 nm, while the seed extract exhibited peaks at 220 and 248 nm, indicating the presence of polyphenols and phytochemicals. High-resolution TEM unveiled spherical and oval-shaped AgNPs with diameters ranging from 6.44 to 28.50 nm. The SEM exhibiting a spherical shape and a polydisperse nature, thus providing insights into the morphology of the AgNPs. EDX analysis confirmed the presence of silver atoms at 10.01% in the sample. XRD results unequivocally confirm the crystalline nature of the AgNPs suspension, thereby providing valuable insights into their structural characteristics and purity. The antioxidant properties of AgNPs, C. occidentalis seed extract, and butylated hydroxytoluene (BHT) were assessed, revealing IC50 values of 345, 500, and 434 μg/mL, respectively. Antibacterial evaluation against Bacillus subtilis, Staphylococcus aureus, and Escherichia coli demonstrated heightened sensitivity of bacteria to AgNPs compared to AgNO3. Standard antibiotics, tetracycline, and ciprofloxacin, acting as positive controls, exhibited substantial antibacterial efficacy. The green-synthesized AgNPs displayed potent antibacterial activity, suggesting their potential as a viable alternative to conventional antibiotics for combating pathogenic bacterial infections. Furthermore, potential biomedical applications of AgNPs were thoroughly discussed.

“…Sediments. In the water, silver is likely to bind to other compounds and be deposited in aquatic sediments [18]. This corresponds to the characteristics of river sediments that generally absorb metals in waters through a series of physical and chemical processes [19,20].…”

“…The pattern shows that the concentration increases as the rivers flow downstream. Silver spreads unevenly along the river because its upper, middle, and lower reaches have varying hydrological characteristics that determine sediment movement [18]. Kotagede is an urban area characterized by low-flow discharge [21] and perennial flow [22].…”

Silver is a hazardous heavy metal that can be found in waters due to effluents from silver crafting. This research aimed to determine the silver contents of effluents from the silver craft industry in Kotagede, Yogyakarta, and analyze the distribution of silver in the receiving bodies of water: Gajahwong and Mantras Pioro River segments. Laboratory tests were conducted to calculate the presence of silver in effluents, river water, and river sediments, and a correlation analysis was employed to investigate the spatial correlation between silver concentrations and silver craft industries. Laboratory test results found silver at <0.0024-88.48 mg/L in effluents. When disposed of into the river, the silver-containing effluents cause contamination in both river segments, as evidenced by <0.0024 mg/L of silver in the water and 2.80-4.04 mg/Kg in the sediment. The distribution pattern also suggested that the concentration of silver increases as the number of silver craft industries on each side of the two river segments increases. In conclusion, the distribution of silver craft industries influences the spread of silver content in the Gajahwong and Mantras Pioro segments.

The application of organic matter with a high nitrogen (N) content in combination with the application of wood charcoal is a common soil fertility management practice in Ultisols. This study aims to determine the availability of N in Ultisols, which are applied to swallow droppings and wood charcoal. The experimental design used was a two-factor Completely Randomized Design (CRD), with the first factor being swallow droppings (0.5 and 10 t ha−1) and the second factor being wood charcoal (0, 10, and 20 t ha−1), with as many as three repetitions. As much as 200 g of soil was put into the incubation site, then swallow droppings and wood charcoal were added according to the treatment, stirred until evenly distributed, and then incubated at 70% field capacity for 14 days. The contents of NH4+, NO3-, and pH were observed at the end of the incubation period. The results showed that the application of swallow droppings and wood charcoal increased the content of NH4+, NO3-, and mineral N but lowered soil pH. The best treatment was given to swallow manure at 10 t ha-1 which increased mineral N by 59%, and a combination of swallow manure 10 t ha-1+10 t ha-1 wood charcoal which increased nitrate content by 1,666%. The results of this study indicate that the application of swallow droppings combined with wood charcoal can increase the availability of N in Ultisols.
