Abstract

The research on the Utilization of Anthocyanin Extract from Parijoto (Medinilla speciosa) as a Sensitizers in Dye Sensitized Solar Cell (DSSC) aims to identify the presence of anthocyanin compounds in parijoto fruit and determine how much power can be generated from anthocyanin compounds as sensitizers in DSSC using variations of ethanol, methanol, ethanol-citric acid (50:50), methanol-citric acid (50:50) solvents through the maceration method for 48 hours. The highest yield was the methanol-citric acid extract from the fruit, which was 16.35%. Positive results in the identification of anthocyanin compounds that were dripped with NaOH showed a color change from red to green-blue and when dripped with HCl there was no color change. The results of the functional group characterization of the fruit ethanol extract through FTIR (Fourier Transform Infrared) analysis showed the presence of -OH groups, -C=C aromatic and -CO alcohol at a wave number of 3293 cm-1, 1644 cm-1, and 1019 cm-1, while from the GCMS (Gas Chromatography Mass Spectrometry) analysis in the fruit ethanol extract there was a cyanidin structural framework at a retention time of 12.24 minutes with a value (m/z) of 243, and an area% of 1.09%. The power measurement on the fruit ethanol extract was 0.1516 mW and on the fruit ethanol-citric acid extract was 0.023 mW. The power generated indicates that the parijoto fruit extract has the potential as a sensitizer in the Dye-Sensitized Solar Cell (DSSC) application.

Abstract

Indonesia has a variety of processed food products made from beans, one of which is tempeh. A traditional Indonesian dish, tempeh is made from soybeans (Glycine max). The bioactive isoflavones contained in tempeh possess phenolic groups that contribute to its antioxidant properties. In addition to isoflavones, compounds such as superoxide dismutase and tocopherol also exhibit antioxidant activity. This study aimed to evaluate the antioxidant activity of tempeh extracts by varying the concentrations of ethanol in the solvent: 96% ethanol, 70% ethanol, 50% ethanol, 30% ethanol, and water. Extraction was performed using ultrasonic-assisted extraction, and antioxidant activity was assessed using the DPPH method, both qualitatively (via dynamolysis and TLC) and quantitatively (using UV-Visible spectrophotometry). The results from the qualitative antioxidant tests using dynamolysis and TLC showed potential antioxidant activity, evidenced by a yellow color change after the sample was sprayed with 0.2% DPPH reagent. Quantitative UV-Visible spectrophotometric testing with quercetin as a standard yielded an IC50 value of 2.86 µg/mL. The IC50results for the extracts in decreasing order of ethanol concentration were as follows: 96% ethanol extract (2638.49 µg/mL), 70% ethanol extract (2559.49 µg/mL), 50% ethanol extract (2288.65 µg/mL), 30% ethanol extract (1945.54 µg/mL), and water extract (2946.45 µg/mL). The highest antioxidant activity was observed in the 30% ethanol tempeh extract, while the lowest antioxidant activity was found in the water extract. These findings indicate that tempeh extracts exhibit antioxidant activity, which varies depending on the ethanol-water solvent composition.

Abstract

Peronema canescens Jack (commonly known as sungkai) is an endemic medicinal plant native to Sumatra and Kalimantan, known for its broad spectrum of pharmacological activities, including antioxidant, antibacterial, antidiabetic, antihyperuricemic, and anti-inflammatory effects. These properties are largely attributed to its high content of bioactive phenolic and flavonoid compounds. Conventional extraction techniques typically utilize organic solvents such as ethanol or methanol, which raise concerns regarding toxicity, cost, and environmental sustainability. This study explores a green extraction strategy employing Natural Deep Eutectic Solvents (NADES), formulated from sodium acetate and glycerol at varying molar ratios, to optimize the recovery of antioxidant compounds from sungkai leaves. The extraction process involved maceration for 2 × 24 hours. FTIR analysis identified key functional group absorptions (O–H, C–H, C=C), with distinct spectral shifts and intensity variations, indicating interactions between NADES components and bioactive molecules. Among the four tested formulations, NADES 4 (sodium acetate:glycerol, 1:3) yielded the highest total phenolic and flavonoid contents, and exhibited the strongest antioxidant activity, with an IC50 value of 32.30 ppm—classified as very strong and comparable to ascorbic acid. These results demonstrate that the compositional adjustment of NADES significantly influences solvent polarity and extraction efficiency, underscoring their promise as sustainable alternatives for the extraction of natural antioxidants.

Abstract

Mixed matrix membranes (MMMs) have gained considerable attention as a cutting-edge filtration technology, leveraging the combined advantages of polymer and inorganic fillers. Metal-organic frameworks (MOFs), as a nanoporous materials, are regarded as highly effective fillers in MMM, significantly enhancing molecular separation efficiency. This article provides a comprehensive review of the synthesis, properties, and performance of polymer/MOFs-based MMMs. A comprehensive literature search was conducted using ScienceDirect and Google Scholar with keywords such as metal-organic framework, MMMs, polymers, filler, and membrane filtration. Polymer/MOFs-based MMMs are synthesized using techniques including in situ and layer-by-layer assembly methods. The MMMs exhibit porosity distribution ranges from57 to 78.3%, contact angle ranges from 45° to 75.27°. The MMMs have also demonstrated exceptional performance in water permeability and bovine serum albumin (BSA)/salts rejection reached up to 94.03 L/m2.h and 99.8%, respectively. These finding highlight the significant potential of polymer/MOFs-based MMMs for advanced water filtration application.

Abstract

Acid-base titration is a common technique used in quantitative analysis in laboratories, with the indicator playing a crucial role in the process. However, synthetic indicators are often costly and can contribute to environmental pollution. As a result, there is a need for alternative, natural acid-base indicators that are affordable and easily accessible. One potential natural indicator is anthocyanin, a pigment found in plants. This study aims to develop an alternative acid-base indicator from the anthocyanin extract of water henna flowers and evaluate its performance in acid-base titrations. The process involved preparing the water henna flower extract, determining its dissociation constant (pI), and testing its effectiveness in acid-base titrations. The pI was found to be 4.22, and the extract exhibited a color change within the pH range of 3.22-5.22, making it suitable for use in acid-base titrations. The water henna flower extract successfully showed clear color transitions at the endpoint of base titrations and provided results comparable to those obtained using methyl orange, accurately determining HCl concentration and sodium bicarbonate levels. This suggests that water henna flower extract can be used as a cost-effective, easily prepared, and environmentally friendly alternative to synthetic indicators like methyl orange.

Abstract

Silica can be produced through hydrolysis in alkaline conditions via the Stober process and has two main functional groups, namely siloxane (Si-O-Si) and silanol (Si-OH). Vinyl modified silica can be produced from the hydrolysis of tetraethyl orthosilicate (TEOS) and vinyl trimethoxysilane (VTMS) with 25%(v/v) ammonia. VTMS is used as a silica surface modifying agent. The resulting silica-vinyl modification is then used as a stationary phase to fill a High Performance Liquid Chromatography (HPLC) column. The aim of this research is to synthesize vinyl-modified silica as a HPLC stationary phase and test its performance. Silica-vinyl modification is carried out by first synthesizing silica from TEOS and then modifying the surface using VTMS. Characterization was carried out using a Scanning Electron Microscope (SEM) and Fourier Transform Infrared Spectroscopy (FTIR). SEM characterization gave a spherical shape and a diameter of 1.73-2.02 μm. FTIR identification gave good results with the identification of siloxane signals (Si-O-Si) at 1,097 cm-1 on silica and 2,850 cm-1 and 2,922 cm-1 which were C-H vibrations on silica-vinyl. Qualitative identification carried out by the addition of alkenes with I2 also shows the binding of vinyl groups to the silica surface. The modified silica is then loaded into a 50 mm x 4.6 mm column. The performance test was carried out by separating caffeine and paracetamol compounds. Optimum separation of MeOH:HOH 1:99 eluent with a flow rate of 1 mL/min. The resulting resolution is 1,80 and selectivity is 1.52. The resulting calibration curve has an R2 value of 0.99156 for caffeine and 0.99431 for paracetamol.

Abstract

Diabetes mellitus is a metabolic disorder characterized by elevated blood sugar levels, which result from impaired insulin excretion or sensitivity. Among the various medicinal plants utilized by the Indonesian population, roselle (Hibiscus sabdariffa L) stands out as a potential remedy for several diseases including diabetes mellitus. This study aims to assess the inhibitory potential of roselle on α-amylase enzyme activity. The roselle calyx extraction method was performed through multilevel maceration using n-hexane and ethyl acetate solvents. Testing the activity of inhibiting the α-amylase enzyme was carried out in vitro using acarbose as a comparison. The findings revealed that the n-hexane extract of roselle calyx exhibited potent α-amylase enzyme inhibition with an IC50 value of 20.43 µg/mL. Similarly, roselle calyx ethyl acetate extract demonstrated strongl α-amylase enzyme inhibitory activity, characterized by an IC50 value of 10.13 µg/mL. Meanwhile, acarbose exhibited robust α-amylase inhibitory activity, possessing an IC50 value of 4.04 µg/mL. It is worth noting that all these substances displayed α-amylase enzyme inhibitory activity in the very active category, although their efficacy was not equivalent to acarbose.

Abstract

Hypercholesterolemia is closely related to cardiovascular disease, which can increase the risk of atherosclerosis. Oxidative stress is related to the development of atherosclerosis because it is related to cellular responses triggered by an imbalance between oxidants and reductants in various layers of blood vessel tissue. K. anthotheca has pharmacological benefits as an antileishmaniasis and antimalarial. The purpose of this study was to determine the antioxidant and anticholesterol activity of K. anthotheca bark based on the type of solvent and to determine the phenolic and flavonoid content of the most active extract. The results indicated that ethyl acetate extract had the best antioxidant activity compared to n-hexane and ethanol extracts, with an IC50 value of 47.82 ppm, followed by ethanol extract at 48.46 ppm and n-hexane extract at 101.89. The value of antioxidant activity is directly proportional to the anticholesterol activity, where the ethyl acetate extract has an EC50 value of 20.42 ppm, the ethanol extract 445.58 ppm, and the n-hexane extract 1,073 ppm. The ethyl acetate extract has a phenolic content of 229.765 mgGAE/g extract and a flavonoid content of 7.63 mgQE/g.
