Abstract

Drymoglossum piloselloides is one of the epiphytic plants that is commonly found in Southeast Asia region. In this study, the ethanol extract of D. piloselloides plant has been used in the green synthesis of silver nanoparticles. The synthesized silver nanoparticles were characterized by ultraviolet-visible (UV-Vis) spectrophotometry, X-ray diffraction (XRD),Fourier-transform infrared (FTIR) spectroscopy, and transmission electron microscopy (TEM) measurements. The UV-Vis spectrum of silver nanoparticles showed a maximum wavelength at 453 nm. The XRD measurement showed the silver nanoparticles peaks at 38.38°, 44.60°, 64.76°, and 77.62°. The FTIR spectra provided evidence of the interaction between silver and chemicals in the plant extract as a weak signal at 682 cm-1. Meanwhile, TEM revealed an average size of 12.63nm. The synthesised silver nanoparticles were utilised for the reduction of 4-nitrophenol with a conversion percentage of up to 100% with a reduction reaction rate constant of 7.104 s-1. In addition, methylene blue was also successfully reduced with the synthesised silver nanoparticles as the catalyst with a reduction reaction rate constant (k) of 21.150 s-1. This study highlights the superior advantage of utilizing ethanolic extract of D. piloselloides to prepare silver nanoparticles with promising catalytic reduction purposes.

Abstract

This study has succeeded in synthesizing and characterizing TiO2/CaTiO3 perovskite composites using calcium carbonate (CaCO3) from shellfish waste (Pinctada maxima). Synthesis was carried out through the coprecipitation method with variations in the molar ratio of CaCO3:TiO2 and calcination temperatures (700oC, 800oC, and 900oC). Characterization was carried out using FTIR, DTA-TG, XRD, SEM-EDS, BET and UV-Vis. The results of the analysis showed that the calcination temperature affected the powder color, crystal structure, thermal properties and particle size. The DTA-TG analysis shows that increasing the calcination temperature up to 900oC significantly reduces mass loss to 51.88%, with minimal thermal events, indicating the formation of a thermally stable and well-crystallized TiO2/CaTiO3 structure. At a temperature of 900oC, a more perfect CaTiO3 was formed with the whitest powder color, the anatase and brookite phases of TiO2 were still detected, while the calcite phase was still found at a temperature of 700oC. The morphology of the samples showed agglomeration with increasingly uniform particle sizes at higher calcination temperatures. Complementary BET analysis confirms that the composite possesses a mesoporous structure with a specific surface area of 11.42 m2/g and a pore size distribution of 3-5 nm, making it suitable for adsorption and photocatalytic applications. UV-Vis analysis showed an increase in the band gap value along with the increase in the TiO2 ratio. This is also confirmed by the presence of Urbach energy which tends to increase with increasing TiO2 ratio.

Abstract

This research aims to determine the performance of the Diesel Particulate Filter (DPF) in reducing exhaust gas opacity, smoke temperature and noise levels on the 1997 Isuzu Panther. The DPF used in this research is made of copper and stainless steel with a metallic honeycomb model. This experimental study involved installing a DPF on a standard diesel vehicle exhaust system and measuring exhaust emissions, smoke temperature and noise levels. The measuring instrument used to test the opacity and temperature of the exhaust gas is a smoke opacity meter based on the SAE-J1667 test procedure (snap acceleration test procedure). Meanwhile, to test the noise level, a sound level meter based on ISO/FDIS 5130:2006 (E) standard was used. Tests were carried out under various conditions including standard exhaust testing (Non-DPF), standard exhaust with DPF (DPF), DPF with 50 gram stainless steel material (DPF + SS50), DPF with 100 gram stainless steel material (DPF + SS100), and DPF made of 150 gram stainless steel (DPF + SS150). The test results showed that DPF had a significant effect on reducing exhaust opacity, smoke temperature and noise level of the 1997 Isuzu Panther. The greatest reduction in exhaust opacity, smoke temperature and noise level were produced by DPF + 150 gram stainless steel with exhaust opacity that could be reduced by 87, 1 ± 1.1%, smoke temperature of 43.2 ± 1.7%, and noise level of 15.2 ± 1.3%. These findings open up opportunities for the development of DPF technology that is more efficient in reducing diesel vehicle emissions, contribute to stricter emissions regulations, and support filter design innovation to improve air quality and reduce the negative impact of vehicles on the environment. In addition, the results of this research show that the use of DPF is in accordance with the diesel vehicle emission threshold regulations set in Indonesia.
