Abstract

perkembangan sintesis dan aplikasi dari MCM-41 memberikan dampak yang positif di berbagai bidang di dunia. Komponen penting dalam sintesis ini adalah sumber silika. Di Indonesia banyak varietas tumbuhan yang dapat dijadikan sumber silika. Dengan beragamnya sumber tersebut maka diharapkan agar dimasa depan ditemukan alternatif silika bahan alam selain yang sudah ada saat ini. Telaah pustaka ini dilakukan dengan mengumpulkan, memilah, dan menelaah berbagai pustaka dalam Bahasa Indonesia dan/atau Melayu terkait perkembangan, sintesis dan aplikasi dari MCM-41. Dalam melakukan sintesis terdapat dua jenis, yaitu sintesis konvensional dan sintesis tak langsung. Analisis menggunakan beberapa instrumentasi seperti difraksi sinar-X, Fourier Transform Inframerah, dan scanning electron microscope dalam menentukan karakteristik padatan MCM-41 yang dihasilkan. Adanya artikel telaah ini diharapkan dapat menjadi gambaran dan rujukan ilmiah bagi pengembangan material sejenis di masa daring.

Abstract

Penelitian ini bertujuan untuk mengetahui aktivitas sitotoksik ekstrak metanol daun dan batang kayu gadis terhadap Artemia salina Leach dengan metode Brine Shrimp Lethality Test (BSLT). Uji sitotoksik menggunakan 10 ekor larva Artemia salina yang berumur 48 jam pada setiap konsentrasi uji dengan tiga kali ulangan. Ekstrak metanol daun kayu gadis dibuat 3 variasi konsentrasi, yaitu 10 ppm, 100 ppm, dan 1000 ppm, sedangkan ekstrak metanol batang kayu gadis dibuat 4 variasi konsentrasi, yaitu 1 ppm, 2 ppm, 4 ppm dan 6 ppm. Sebagai kontrol digunakan pelarut untuk melarutkan ekstrak. Setelah 24 jam diamati kematian Artemia salina, ditentukan persentase mortality, dan dihitung nilai LC50 menggunakan analisis probit. Hasil penelitian menunjukkan aktivitas sitotoksik ekstrak metanol batang kayu gadis lebih tinggi dari pada ekstrak metanol daunnya, dapat dilihat dari LC50 ekstrak metanol batang lebih kecil (0,79 ppm) daripada ekstrak metanol daunnya (544,81 ppm). Ke-dua ekstrak memperlihatkan kematian 50% hewan uji pada konsentrasi lebih kecil dari 1000 ppm, yang artinya aktivitas sitotoksik yang diberikan berkorelasi positif dengan aktivitas anti kanker. Berdasarkan tinjauan literatur senyawa-senyawa yang berhasil diisolasi dari daun dan batang kayu gadis adalah flavonoid, fenil propanoid, lignan, kumarin, fenolik, asam lemak, dan alkohol. Diharapkan beberapa senyawa tersebut dapat berpotensi sebagai antikanker dimasa mendatang.

Abstract

The most interesting and well-known research in the field of gold nanomaterials synthesis is the use of "green chemistry" to prepare gold nanoparticles (AuNPs). In this study, Peronema canescens leaf extract was used as the synthesis medium to successfully produce AuNPs in a way that was cheap, quick, and good for the environment. A UV-visible spectrophotometer, particle size analysis (PSA), and transmission electron microscopy (TEM) were used to find out more about the AuNPs that were prepared. The UV-visible spectrophotometer showed a surface plasmon resonance peak at 532 nm, which proves https://www.fortyouncewines.com/ that AuNPs exist in the solution. TEM and PSA both showed that the AuNPs were mostly spherical and had an average diameter of 14.9 nm, respectively. In the presence of NaBH4, the AuNPs were found to speed up the reduction of rhodamine B (RhB), metanil yellow (MY), and 4-nitrophenol (4-NP). The results show that the AuNPs that were prepared in a new way worked very well and could be used in catalysis.

Abstract

ABSTRACT. Azadirachta excelsa is a plant belonging to the same genus as the Indian neem (Azadirachta indica) which is expected to have similar biological activities. However, its active components and pharmacological effects are limited. The composition and quantity of these metabolites in A. excelsa may differ due to different polarities of extracting solvents, so selecting an effective extractive solvent with a high level of biological activity is important. Therefore, in this study, we examined differences in the metabolite finger printing using FTIR-based metabolomics, as well as evaluated their antibacterial activity against Staphylococcus aureus (ATCC 6538) and Escherichia coli (ATCC 8739). A. excelsa was extracted using chloroform, ethyl acetate, ethanol p.a., 70% and 50% ethanol. Extracts obtained were analyzed using FTIR and the inhibition zones were then determined. The results showed that principal component analysis (PCA) could distinguish each sample based on the extraction solvent. In this study, we found 50% and 70% ethanol extracts had similar metabolite compositions and concentrations based on their respective FTIR spectrum. The inhibition zone of A. excelsa extracts ranged from 12.37-17.20 mm and 13.88-15.89 mm against S. aureus and E.coli, respectively. The chloroform extract was more effective against both bacteria. Duncan's further test showed that chloroform extract reduced E. coli similarly to ethyl acetate but not S. aureus. While 50%, 70%, and ethanol p.a. extracts inhibited S. aureus and E. coli equally. Based on these results, the polarity of the extracting solvent had an important influence on the metabolite profile and antibacterial activity of A. excelsa. Keywords: Azadirachta excelsa, antibacterial activity, metabolite fingerprinting, FTIR.

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. Keywords: Antibacterial, TLC-bioautography, Peronema canescens Jack, Staphylococcus aureus, Staphylococcus epidermidis
