Abstract

Rice husk is a by-product of rice processing that has many uses but is rarely used by most people. Rice husk has abundant silica content which can be used as an adsorbent. This research was conducted to separate silica from rice husk by using the alkali fusion method with varying heating times (30, 60, 120, and 180 minutes) and to characterize silica using FTIR, XRD, and SEM-EDS. the maximum silica yield achieved was 50.75% after heating 60 minutes. The results of XRD characterization showed the presence of a spectrum in the 22o region at an angle of 2θ with a non-sharp spectral shape which is an amorphous nature of silica. In the FTIR test, there is a typical absorption of the silanol group in the absorption area of 1099.48 cm-1, while the results of the SEM-EDS analysis show the percentage of silica mass is 34.39%.

Abstract

Increased exposure to free radicals and chronic inflammatory processes are major factors in the development of various degenerative diseases, including cancer, diabetes, and cardiovascular disease. Therefore, the search for natural bioactive compounds with antioxidant and anti-inflammatory properties has become a major focus in pharmaceutical and biomedical research. Phycocyanin is a complex protein pigment from the microalgae Spirulina platensis which is known to have biological activities, especially as an antioxidant and anti-inflammatory. This study aims to evaluate the antioxidant and anti-inflammatory properties of phycocyanin extract obtained through maceration and freeze-thawing methods using PBS solution pH 7.4 and distilled water. Antioxidant activity was evaluated using the ABTS (2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonate)) method, while the anti-inflammatory potential was tested using the protein denaturation inhibition method. The test results showed that the phycocyanin extract had quite strong antioxidant activity with an IC₅₀ value of 82.86 mg/L. In addition, anti-inflammatory activity was also shown with an IC₅₀ value of 73.92 mg/L in the protein denaturation inhibition test. These results indicate that phycocyanin extract from Spirulina platensis has the potential as a natural bioactive agent in the development of nutraceutical, cosmetic, and pharmaceutical products. Further studies are needed to understand the molecular mechanisms and in vivo testing to support its clinical application.

Abstract

Cancer is recognized as a leading cause of death globally, responsible for approximately 14.5% of all deaths,. Cyclosenegalin A showed activity against DU-145 human prostate cancer cell line with IC50 of54.92.35μM. This study aims to investigate whether the cyclosenegalin A compound can interact with the target receptors 4IEH and potentially act as an anticancer candidate. The results of the study show that the docking of cyclosenegalin A with the 4IEH receptor yielded the best results, with an affinity value of -8.88 kcal/mol. The hydrogen bonding at the GLY 104, ASP 70, VAL 92, and GLU 95 amino acids was identical to that observed in the standard ligand, n-heteroarilsulfonamides. The interaction between cyclosenegalin A and the target receptor is effective, indicating that cyclosenegalin A holds potential as an anti-cancer candidate.

Abstract

This research aims to characterize charcoal resulting from pyrolysis of human hair waste which is activated by KOH solutions using FTIR, XRD and SEM instruments. The human hair charcoal obtained from pyrolysis then goes into the particle size reduction process using a 60 and 100 mesh sieve. It is then activated using KOH and then the results of the activation are analyzed using FTIR, XRD instruments assisted by software. Origin and Ms. Excel, then SEM assisted by Image-J software . The ash content test results show that the amount of minerals and metals in human hair charcoal tends to increase.

Abstract

The dependence of optical microscopes on one of the consumables, especially at high magnification, so that the imaging results are clearly visible or not blurry, is immersion oil. In an effort to answer this need, a study has been conducted to find an alternative immersion oil by utilizing vegetable oil from the kepuh plant (Sterculia Foetida L) from Alor Regency. This study tested the quality of kepuh seed meat oil from soxhlet extraction and purified using the Deguming, Neutralization, Bleaching, Stearin, Centrifugation methods, and stored in glass bottles, wrapped in aluminum foil, and stored at room temperature (25-280C) from 2016 to 2024 (8 years). The test used three parameters, namely first; comparison of physical and chemical properties parameters, namely density, viscosity, refractive index, acid number and Aperture Value for kepuh oil data in 2016 and 2024, were recorded to have changed, but the imaging photographs still provided the same brightness as standard oil. Second; the GC-MS identification parameters showed that, even though there were 32 peaks in the kepuh oil spectrum, and the nomination of two compounds was identified, namely linoleic acid 34.58%, stearic acid 6.98%, the imaging effect was still clearly visible. Third, a comparison of the imaging results of standard immersion oil and immersion oil from kepuh for oil conditions in 2024 showed imaging results that were not significantly different.

Abstract

Rice is an energy source that is high in carbohydrates and contributes to providing the largest percentage of calories, but rice has a low protein, vitamin and mineral content, so it needs to be fortified to increase the nutritional content of rice, especially protein. This research aims to characterize rice that has been fortified with protein hydrolyzate. Synthesis of Payangka fish protein hydrolyzate was carried out using papain enzyme with concentrations of 2,4 and 6% with an incubation time of 2 hours. The best fortification of rice is done by soaking the rice for 4 hours, then drying it again for 14 hours at a temperature of 50oC. The research results show that Payangka fish hydrolyzate can be obtained through hydrolysis of Payangka fish meat using the Papain enzyme with a concentration of 2-6%. The highest protein content of protein hydrolyzate was obtained when using a Papain enzyme concentration of 6% with a protein content of 3.61%. Fortification of rice with Payangka fish protein hydrolyzate can increase rice protein content, namely from 9.43% (before fortification) to 10.38% (after fortification using protein hydrolyzate with a concentration of 30%)

Abstract

This study aims to determine the characteristics of activated carbon from human hair cutting waste and to determine its ability to adsorb metals contained in water. This study uses an experimental method that is preceded by the activation of charcoal with KOH activator. Then continued with characterization using Fourier Transform Infra - Red (FTIR), X-Ray Diffraction (XRD), Scanning Electron Microscope Energy Dispersive X-Ray (SEM-EDS) and Atomic Absorption Spectrophotometer (AAS). The results of the study showed that the FTIR spectrum showed the presence of a groupOH, CH, C=C and CO. The results of SEM analysis of activated carbon show the morphology of the pores of unactivated carbon, namely the surface looks smooth and dense with small particles evenly distributed and there are no large pores or significant cracks. Activated carbon from activation with KOH has a surface structure that looks more porous than before activation. The results of EDS analysis show the elemental composition of unactivated carbon and after activation using KOH only the C element is produced. XRD analysis of unactivated activated carbon shows one wide and not sharp diffraction peak. This characteristic indicates that the material has an amorphous structure, which means that the atoms in the material are not arranged crystalline but randomly. The relatively low diffraction intensity and high background strengthen the amorphous character of this pyrolysis carbon. After activation using KOH, the diffraction pattern still shows a wide peak at the same 2θ, but with higher intensity and a more defined peak shape. The results of AAS analysis show that activation with KOH provides high adsorption efficiency of 26.82%.

Abstract

The study of borax contamination on SRM Tomato Leaves NIST no. 1573a was succesfully analized. This study used sausage samples using Spectrophotometry Fluoresence method. Boron analysis by fluorescence spectrophotometry was done by excitation at 522 nm and emission at 593 nm. Validation method uses linear standard curve in the concentration range of 1-4.5 ppm with R2 = 0.9991. The sensitivity, limit of detection, limit of quantification, and percent recovery are 4695.7 a.u.ppm-1, 0.241±0,06 ppm, 0.805±0,06 ppm, and 92.8%, respectively. This means that determining boron using the borate ester distillation method with fluorescence spectrophotometry can be used as a new method for determining boron levels in food samples.
