Abstract

Medicines can cause changes in the physiology or psychology of an organism when consumed. In general, medicines consist of several mixtures of active ingredients such as paracetamol (PCT), propifenazone (PRO), and caffeine (KAF), which are often found in several types of branded medicines that are claimed to be able to cure or treat. This research aims to obtain a type of solvent that has the smallest photometric error value and can completely dissolve the active ingredient mixture of PCT, PRO, and KAF. In general, organic solvents such as ethanol and methanol are very often used to dissolve compounds that mix with each other, but these solvents cannot always dissolve other active substances. Therefore, researchers carried out an analysis of several types of solvents that could dissolve the three active ingredients. Solvents that can dissolve perfectly without any specification stage must go through a solvent optimization process. The types of solvents that will be tested are methanol, HCl 0.1N, phosphate buffer pH 7.2, and the ratio of phosphate buffer: methanol (DM) (DM 9:1 pH 7.4), (DM 7:3 pH 7.8), (DM 5:5 pH 8.3), (DM 3:7 pH 8.9), and (DM 1:9 pH 9.6). The results of this research show that the solvent that has the smallest photometric error value and can completely dissolve the three active substances is the DM 7:3 pH 7.8 solvent with a total percentage of 0.0846%, which is the smallest value compared to other solvents that have been optimized.

Abstract

People still do not utilize freshwater lobster (Cherax quadricarinatus) shells optimally, even though the chitin compound contained in this waste can be modified into chitosan through chemical reactions. Chitosan obtained from freshwater lobster shells can be used as an antibacterial. This study aims to test the antibacterial activity of chitosan from freshwater lobster shell waste against Escherichia coli bacteria. Making chitosan is carried out through three processes, namely, demineralization, deproteination, and deacetylation stages. Then, characterization of the chitosan is carried out, which includes water content, ash content, yield, and solubility. The research results showed that the chitosan obtained in this study was 43.96%, and the degree of deacetylation value of freshwater lobster shell chitosan was 75.11%. Chitosan with a concentration of 0.3, 0.5, 0.7, and 0.9% provides an inhibition zone of 13.5, 15.9, 16.8, and 17.2 mm, respectively, against Escherichia coli. Thus, a concentration of 0.9% chitosan from freshwater lobster shells has better antibacterial activity and is categorized as having strong inhibitory power.

Abstract

Kepah clams (Polymesoda erosa) are one of the few aquatic animals that have a body and are protected by two cupped shells. Many people consume this shellfish meat, but many of the shells are thrown away by local people so that they only become waste. It is this shell waste that needs to be processed properly because it is known that shells are one of the fishery ingredients that contain chitin. One way to make kepah clams have a higher economic value is by isolating kepah clams into chitosan. The purpose of this study was to isolate and characterize chitosan from mussel shells and to determine functional groups using Fourier infrared (FTIR). The isolation methods used were deproteination, demineralization, depigmentation, deacetylation, and chitosan characterization. The results showed that the yield of the transformation of chitin into chitosan in cockles was 85.77% and had a brownish-white powder texture and no odor. The water content in the chitosan of the clam shells obtained was 1.53%, the ash content was 0.50%, and the degree of deacetylation obtained was 75%.

Abstract

Staphylococcus hominis and Pseudomonas aeruginosa bacteria are normal flora bacteria found on the surface of human skin, and in certain circumstances can cause infections in the body of a person with a weak immune system. Infection of both bacteria can cause body odor that can affect a person's social relationships. The use of natural antibacterials has minimal side effects, namely lemon peel which is waste from lemons. Lemon juice is commonly used by the public, but not many people know that lemon peel has great benefits like lemon juice. The objective of the research was to determine the chemical compounds contained in the n-hexane fraction, ethyl acetate of lemon peel and antibacterial activity in ethanol extract, n-hexane fraction, ethyl acetate of lemon peel (Citrus x limon (L.) Burm. f.) This research method was an experimental method that includes sample collection and processing, characterization of simple drugs, preparation of 96% ethanol extract, n-hexane fraction, ethyl acetate fraction, phytochemical screening, and antibacterial activity test using the agar diffusion method at concentrations of 10%, 20%, 30%, 40%, 50%. The results of phytochemical screening in the ethyl acetate fraction contain alkaloids, flavonoids, tannins, triterpenoids, and in the n-hexane fraction shows the presence of triterpenoid chemical compounds. Ethanol extract, n-hexane fraction and ethyl acetate fraction of lemon peel have antibacterial activity on Staphylococcus hominis and Pseudomonas aeruginosa bacteria. The results of the three samples tested for the greatest inhibitory power in the ethyl acetate fraction showed intermediate results, almost comparable to the inhibitory power of the positive control ciprofloxacin.

Abstract

Bacterial infection is a global health problem that requires special attention, especially due to increasing resistance to antibiotics. This study aims to determine the antibacterial activity of ethanol extract, n-hexane fraction and ethyl acetate fraction of cardamom fruit (Amomum cardamomum Soland. Ex Maton Benth) against Streptococcus pyogenes and Pseudomonas aeruginosa bacteria. The extraction was done by percolation using 96% ethanol, followed by fractionation using n-hexane and ethyl acetate solvents. Phytochemical screening tests showed the presence of alkaloid, flavonoid, tannin, and saponin compounds known to have antibacterial activity. Antibacterial activity test was conducted using disc diffusion method with five concentrations (10%-50%). The results showed that the ethyl acetate fraction had the greatest inhibition, with the highest inhibition zone against Streptococcus pyogenes of 14.1 mm and Pseudomonas aeruginosa of 16.8 mm at 50% concentration. Inhibition increased with increasing concentration. The ethyl acetate fraction proved to be the most effective because it contains semipolar compounds that are able to penetrate the bacterial cell wall. This study supports the potential of cardamom fruit as an alternative natural antibacterial agent.

Abstract

Background: Hydrogels are topical preparations applied to the skin surface. Chitosan, a compound derived from the deacetylation of chitin, has various benefits, including antifungal activity. Utilizing waste from bamboo clam shells (Solen courneus) collected in Belawan waters as a source of chitosan could provide a sustainable solution for developing antifungal hydrogel formulations. Objective: This study aimed to produce chitosan from bamboo clam shells, formulate it into a stable hydrogel, and evaluate its antifungal activity against Trichophyton mentagrophytes. Methods: This experimental study involved isolating chitosan through deproteinization, demineralization, depigmentation, and deacetylation steps. The resulting chitosan was characterized by moisture content, ash content, yield, solubility, and functional group identification using FTIR spectroscopy. Subsequently, chitosan was formulated into four hydrogel variations (0%, 2%, 4%, and 6%). The hydrogel formulations were evaluated for organoleptic properties, homogeneity, pH, viscosity, spreadability, adhesiveness, and antifungal activity. Results: The produced chitosan exhibited functional groups similar to standard chitosan and a degree of deacetylation of 77.5%. Hydrogel evaluation over three weeks showed good stability, with pH values of 4–6.5, spreadability of 5–7 cm, adhesiveness greater than 1 second, and viscosity ranging from 3,000–50,000 cps, all meeting the required standards. The antifungal test demonstrated that the 6% chitosan hydrogel had the highest inhibition zone (11.5 mm) against Trichophyton mentagrophytes. Conclusion: Chitosan derived from bamboo clam shells was successfully formulated into a stable hydrogel with effective antifungal activity. The 6% concentration exhibited the strongest antifungal effect, indicating its potential as a topical preparation for treating skin fungal infections.
