Abstract

Bacterial infection is a major cause of chronic infection and death that continues to threath public health worldwide. Improper use of antibiotics can cause pathogenic bacteria to become resistant to antibiotics and have side effects, so alternative sources of antibiotics from natural ingredients are needed. One type of plant that is efficacious as an antibacterial is jarak pagar leaves (Jatropha curcas). This study aims to examine the phytochemical content qualitatively using the tube method and the antibacterial activity of the ethyl acetate fraction of jarak pagar leaves using the disc diffusion method. Extraction of jarak pagar leaves by maceration method with 96% ethanol then fractionated with ethyl acetate. Data on the diameter of the inhibition zone in the antibacterial test were analyzed using the non-parametric test, namely the Kruskal Wallis test. The analysis was continued with Mann Whitney's post hoc with a confidence level (pvalue<0.05). Based on the results of the phytochemical test obtained alkaloids, saponins, flavonoids, polyphenols and tannins. The antibacterial activity of the ethyl acetate fraction of jarak pagar leaves at a concentration of 8 mg/mL showed an inhibition zone of 19.73±0.25 mm which was included in the very moderate category and weakly inhibited at a concentration of 0.5 mg/mL which was 4.87±0.31 mm and the results of statistical tests showed that the ethyl acetate fraction of jarak pagar leaves had antibacterial activity and each concentration had a significant effect on inhibiting the growth of S. aureus.

Abstract

This study has succeeded in synthesizing and characterizing TiO2/CaTiO3 perovskite composites using calcium carbonate (CaCO3) from shellfish waste (Pinctada maxima). Synthesis was carried out through the coprecipitation method with variations in the molar ratio of CaCO3:TiO2 and calcination temperatures (700oC, 800oC, and 900oC). Characterization was carried out using FTIR, DTA-TG, XRD, SEM-EDS, BET and UV-Vis. The results of the analysis showed that the calcination temperature affected the powder color, crystal structure, thermal properties and particle size. The DTA-TG analysis shows that increasing the calcination temperature up to 900oC significantly reduces mass loss to 51.88%, with minimal thermal events, indicating the formation of a thermally stable and well-crystallized TiO2/CaTiO3 structure. At a temperature of 900oC, a more perfect CaTiO3 was formed with the whitest powder color, the anatase and brookite phases of TiO2 were still detected, while the calcite phase was still found at a temperature of 700oC. The morphology of the samples showed agglomeration with increasingly uniform particle sizes at higher calcination temperatures. Complementary BET analysis confirms that the composite possesses a mesoporous structure with a specific surface area of 11.42 m2/g and a pore size distribution of 3-5 nm, making it suitable for adsorption and photocatalytic applications. UV-Vis analysis showed an increase in the band gap value along with the increase in the TiO2 ratio. This is also confirmed by the presence of Urbach energy which tends to increase with increasing TiO2 ratio.
