Abstract

Mahogany rind which is underutilized in the environment contains secondary metabolites that have the potential as insecticides such as alkaloids, flavonoids, tannins, and saponins. The purpose of this study was to determine the mahogany rind extract was effective as an insecticide in controlling the mosquito vector Aedes aegypti and to determine the concentration of the mahogany rind extract which was most effective as an insecticide for the Aedes aegypti mosquito. Mahogany rind extraction method with percolation method using ethanol as solvent. The extraction result of mahogany rind was 21 grams with a yield of 5.428%. Mahogany rind extract has effectiveness as an insecticide against Aedes aegypti mosquitoes. The results showed that the higher the concentration of mahogany skin extract, the more the number of Aedes aegypti mosquitoes dead. The lowest killing power to the one that effectively kills mosquitoes is 0.5%, 1%, 2%, and 4% with a mortality of 14.28%, respectively; 21.42%; 45.53% and 57.14%. In the probit analysis LC50 of mahogany fruit peel extract is at a concentration 3.796% and including the poisonous category.

Abstract

Acne is a disease caused by chronic inflammation of the pilosebaceous unit caused by bacteria, one of it is Propionibacterium acnes. Acne treatment can be done using nature component, one of it is sweet arum mango leaves. This study aims to identify which mango leaf extract has a minimum inhibitory power (MIC) which is more effective. The extraction carried out in this study was percolation with 96% ethanol and n-hexane as solvents. The extraction yield of 96% ethanol extract was 3.5%, while the n-hexane extract yielded 2.5%. The MIC results from the inhibitory power test with concentrations of 1%, 3%, 5%, 7%, and 9%, the 96% ethanol extract with a concentration of 1% obtained a value of 2.1 mm, while the n-hexane extract has an inhibitory power starting from a concentration of 5% with an average diameter of 1.26 mm. It can be concluded that the arum manis mango leaf extract (Mangifera indica L. var. arum manis) has an inhibitory effect on the growth of Propionibacterium acnes bacteria and the ethanol extract of arum manis mango leaf has more effective antibacterial activity than the n-hexane extract of arum manis mango leaves

Abstract

Gastrointestinal infection is an infection caused by several bacteria, including Staphylococcus aureus. The heart of Kepok Banana (Musa x paradisiaca L.) contains dietary fiber which can be used for human health, especially digestion. This study aims to determine the extract of the kepok banana flower contains antibacterial properties against Staphylococcus aureus bacteria using the ultrasonic method. Ultrasonic method, this method is an extraction method without heating, the extraction results obtained by the ultrasonic method were 17.58%, the results of the phytochemical screening of the kepok banana flower extract found the presence of alkaloids, flavonoids, tannins, saponins, and phenolics. The results showed that kepok banana flower extract had an inhibitory effect on the growth of Staphylococcus aureus bacteria with a diameter of 1.90 mm at a concentration of 24% which was included in the weak category. Antibacterial test results were analyzed using ANOVA. The results of the statistical analysis showed that there were significant differences in the inhibition zones, namely 0.000 (sig <0.005) between all concentrations. From this study it can be concluded that kepok banana flower extract (Musa x paradisiaca L.) has an inhibitory effect on Staphylococcus aureus bacteria in the weak category at all concentrations

Abstract

Shallot peel (Allium cepa L.) is often considered as waste that is not useful by the community. This study aims to determine the shallot peel extract contains antibacterial against Staphylococcus aureus bacteria using the reflux method. The methods used in this study were sample collection, sample processing, extracting shallot skin samples, alcohol-free test, phytochemical screening, and antibacterial test using the disc method. The extraction method used, namely: Reflux method. This method is an extraction method by heating. the extraction yield obtained from the yield by the reflux method is 4.5%. Positive alcohol-free test results do not contain alcohol in the sample. The results of phytochemical screening of shallot peel extract showed the presence of alkaloids, flavonoids, saponins and phenolics. The results of inhibition test at a concentration of 5000ppm and 10000ppm obtained an average of 2.07 mm and 2,8 mm for each concentration. This research can be concluded that shallot peel extract (Allium cepa L.) has an inhibitory effect on the growth of Staphylococcus aureus bacteria with a weak category.
