Abstract

ABSTACT. The objective of this study was to develop an approach for incorporating titanium oxide or titania into oil palm leaves ash (OPLA) using a simple procedure. The study process comprised the mixing of oil palm leaves (OPL) powder and titanium tetraisopropoxide in chloroform solvent, followed by the elimination of the solvent to obtain a solid residue. Subsequently, the residue obtained was calcined at 500 °C for 5 hours, leading to the production of a yellow-light powder. The results of product characterization using X-ray diffraction (XRD) and scanning electron microscopy analysis showed the presence of titanium oxide in OPLA. In addition, the wide diffractogram detected in XRD analysis revealed the presence of a silica peak. The un-sharp peaks in the regions of 25.6°, 38.2°, 47.9°, 54.5°, and 62.9° showed that the TiO2 particles were pure anatase, and no peaks of other TiO2-anatase phases were detected. Analysis using SEM showed that the surface of the material obtained was irregular and tended to have a hollow shape, while energy dispersive X-ray analysis revealed a SiO2 content of approximately 73%. However, the titanium element or titania was not detected possibly due to its small concentration. The material obtained also had a good catalytic activity for safranin-O dye elimination under sunlight irradiation, which served as the activation energy source. Based on these findings, the use of OPLA (a side product of oil palm plantations) could be evaluated economically due to its effective role in the catalytic process despite the addition of a small amount of titania catalyst. Keywords: Oil palm leaves ash, titania, safranin-O, sunlight irradiation.

Abstract

This study aims to synthesize silver-palm kernel expeller ash (PKE) composites using in-situ combustion at 600 °C. Compared to previous methods, the novel in-situ combustion was developed to easily obtain composites in the laboratory using simple procedures. The products obtained were characterized with X-ray diffraction (XRD) analysis. The results showed that the composites contained silver metal peaks and some peaks of a mixture of compounds predicted to be calcium phosphate, calcium hypophosphate, and other undetermined metal oxides. In addition, X-ray fluorescence (XRF) analysis showed the presence of several important minerals derived from PKE combustion. Composites obtained in this study showed better activity as catalysts in the removal of congo-red under sunlight irradiation compared to only PKE ash. Based on these results, the by-products of palm oil processing had the potential to be used for advanced materials preparation.

Abstract

This research aims to examine the antibacterial activity of an ethanol extract of old sungkai leaves (DST) (Peronema canescens Jack) against the test bacteria Staphylococcus aureus and Staphylococcus epidermidis using the TLC-bioautography method. The concentration of the test extract was 15%, with the amount of extract spotting being 25 μL, and the eluent used was chloroform p.a. The results showed that the TLC chromatogram of DST ethanol extract showed 10 dense spots/spots, 6 spots of which could inhibit the growth of S. aureus (spots no. 2-7), and 7 of them (spots no. 1-7) could inhibit the growth of S. epidermidis. Spots with Rf = 0.06; 0.12; 0.27; 0.35 (spots no. 2-5) showed a larger clear zone than spots with Rf = 0.47 and 0.64 (spots no. 6-7) in inhibiting S. aureus. Meanwhile, spot number 1 (Rf = 0) showed the clearest zone among the other 6 spots in inhibiting S. epidermidis. In conclusion, the ethanol extract of old sungkai leaves (DST) has strong antibacterial properties against S. aureus and S. epidermidis. The results of this research have the potential to be developed to obtain potential candidate compounds as antibacterials from sungkai leaves. Keywords: Antibacterial, TLC-bioautography, Peronema canescens Jack, Staphylococcus aureus, Staphylococcus epidermidis

Abstract

Mangrove (Rhizophora mucronata) is a plant that can be used as an antibacterial because it contains several secondary metabolite compounds such as saponins and flavonoids which can inhibit bacterial growth. This research aims to determinehe antibacterial activity of mangrove leaves (Rhizophora mucronata) in inhibiting the growth of Helicobacter pylori bacteria. This research is an in vitro study using the agar dilution method for 2-5 days. The treatment groups consisted of negative, positive (co-trimoxazole), ethanol extract of mangrove leaves (Rhizophora mucronata) with concentrations of6.25%, 12.5%, 25% and 50%. The treatment was carried out by adding the Helicobacter pylori suspension to a petri dish containing agar media. Observations were made to see whether bacteria grew in the media. The data is then analyzed and broken down from the results of calculating the diameter of the inhibition zone. The test results showed that the ethanol extract of mangrove leaves (Rhizophora mucronata) had antibacterial activity in the weak category in inhibiting the growth of Helicobacter pylori bacteria. This antibacterial activity can be caused because mangrove leaves (Rhizophora mucronata) contain secondary metabolite compounds with an antibacterial mechanism of action, so this is in line with the results of this study.

Abstract

Using ammonium vanadate and natural silica from oil palm leaves in situ at 900oC is a sustainable synthesis method for producing V2O5-SiO2 mixed oxides in the form of a brownish powder. Therefore, this study aims to investigate a more environmentally friendly alternative to synthesizing V2O5-SiO2 using oil palm leaves, a by-product from oil palm farming. The XRD analysis of the reaction products showed specific V2O5 peaks and broadened peaks, indicating the presence of amorphous silica. The Fourier transform infrared (FTIR) analysis, which revealed the presence of Si-O-Si and Si-O-V functional groups, also supported the characteristic assessment. In addition, X-ray fluorescence (XRF) analysis showed that V2O5 (46.70 mass%) and SiO2 (52.60 mass%) were present, along with small amounts of other possible metal oxides, such as P2O5, K2O, CaO, Fe2O3, Al2O3, and PdO.

Abstract

The purpose of this study was to look into the antibacterial activity of methanolic extract of Excoecaria cochinchinensis as well as the effect of its combination with antibiotics on the growth of Klebsiella pneumoniae, Enterobacter aerogenes, and Staphylococcus epidermidis. The antibacterial activity test was carried out using the well diffusion method, and the combined effect of the extract and antibiotics was observed using the paper strip diffusion method. At various concentrations (25, 50, 75, 100, 150, 200, and 250 mg/mL), the extract significantly inhibited the growth of K. pneumoniae, E. aerogenes, and S. epidermidis. The inhibitory zone's diameter increased proportionally with the extract concentration. The growth of K. pneumoniae and S. epidermidis was then classified as extremely sensitive (+++) to the addition of the extract at 200 and 250 mg/mL concentrations, meanwhile, E. aerogenes’s with 250 mg/mL of the extract. Secondary metabolites such as oleanolic acid, arjunolic acid, scopoletin, kaempferol, quercetin, diterpenoid compounds, tannins, and other phenolics have been reported from E. cochinchinensis leaves and are thought to be responsible for its antimicrobial activity. The effect of the extract’s combination with antibiotics was insignificant compared to their individual activity, thereby classifying them as indifferent.
