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 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.

Abstract

Penelitian ini bertujuan untuk mengetahui perbandingan dari pengaruh penambahan aditif sintetik dan alami pada elektrodeposisi nikel, Proses elektrodeposisi nikel merupakan reaksi elektrokimia yang melibatkan elektron yang disuplai oleh sumber arus searah. Reaksi terjadi pada permukaan elektroda. Ion-ion nikel dalam larutan akan tereduksi membentuk lapisan logam nikel di katoda, sedangkan di anoda akan terjadi reaksi oksidasi. Pengaruh aditif sebagai agen pereduksi selain memberikan pengaruh pada mikrostruktur deposit dapat meningkatkan jumlah arus sehingga dapat mempercepat terbentuknya deposit dan memberikan lapisan yang lebih tebal dan kilau. salah satu aditif sintetik adalah natrium lauril sulfat/sodium lauril sulfat, saccharin, Cetiltrimetilamonium Bromida, coumarin dan beberapa aditif alami antara lain Ektrak daun semanggi, Ekstrak daun Ketapang, ekstrak batang bakau, ekstrak buah kakao, dan brightener alami Daphne gnidium L.

Abstract

The objective of this study was to perform a comprehensive evaluation of the application of liquid smoke as a possible antibacterial agent. The studies were identified by conducting searches on multiple electronic databases, specifically Semantic Scholar, PubMed, and Google Scholar, from 2013 to 2024. The keywords used included ‘antibacterial of wood vinegar, antibacterial of pyroligneous extract, antibacterial of pyroligneous acid, antibacterial of wood distillate, antibacterial activity of liquid smoke, and aktivitas antibakteri asap cair (in Bahasa Indonesia)’. The results indicate that liquid smoke has the capacity to serve as a natural antibacterial agent against both Gram positive and Gram-negative microorganisms. The variation in antibacterial susceptibility may arise from the composition of chemical compounds present in liquid smoke, the raw materials employed in its production, the temperature of pyrolysis, and the specific testing methodology employed. This review will be useful to the industrial and scientific communities in the food science, pharmaceutical, and technology fields.

Abstract

This study aims to synthesize chitosan nanoparticles - n-hexane extract of Cinnamomum parthenoxylon (CP) fruit using the ionic gelation method, to characterize them, and to determine their antifungal activity against the wood-rotting fungi Trametes versicolor and Fomitopsis palustris. Chitosan-CP extract nanoparticles were formulated with chitosan:Na-TPP:CP extract ratio of 1:1:0.5. Particle size and polydispersity index were determined using a particle size analyzer (PSA), and particles morphology was observed using a scanning electron microscope (SEM), and antifungal activity was measured using agar media. The results revealed that the average size of chitosan nanoparticles (base) was 276.9 nm, while the average size of chitosan-CP extract nanoparticles was 807.6 nm. The polydispersity index (PI) of both nanoparticles was greater than 0.7. Observations of the nanoparticles' morphology revealed that aggregation/agglomeration formed in the resulting particles. Both nanoparticles chitosan (base) and chitosan-CP extract inhibited the growth of white rot fungi (T. versicolor) more than brown rot fungi (F. palustris), as measured by the inhibitory zone.

Abstract

Brucea javanica L. Merr. has long been used for its antimalarial, anti-diabetic, antibacterial, and antioxidant effects. Its bioactivity depends on both its chemical constituents and the type of solvent employed during extraction. Integrating FTIR and UV-Vis spectral data with chemometric approaches enables classification of fruit extracts based on the solvent used, while GC-MS analysis provides detailed compound identification. Using sonication, extraction with methanol, ethyl acetate, and n-hexane produced yields of 30.61% ± 0.80, 19.20% ± 0.75, and 18.12% ± 0.89, respectively. FTIR spectra were recorded over 600–4000 cm⁻¹, and UV-Vis spectra were measured across 200–800 nm. Analysis showed that ethyl acetate and n-hexane extracts exhibited similar profiles, which differed from that of the methanol extract. PCA successfully distinguished all three extracts, with cumulative PC1 and PC2 values above 70%. FTIR-based PCA provided better separation due to its broader fingerprint region compared to UV-Vis spectra. GC-MS results revealed that the compound profiles were largely similar across the extracts, although more compounds were detected in the methanol extract than in the ethyl acetate or n-hexane extracts.
