“…The increase in ethanol concentration is directly proportional to the total phenol obtained [23]. Similarly, the effect of power according to research conducted by [24] the higher the power on the MAE used, the hotter the resulting temperature, so that the energy produced in the MAE is radiation, and rotation, therefore the presence of microwave radiation, and rotating vibrations will cause the pressure on the cell wall to increase, then the cell swells and more bioactive compounds are released or obtained. minutes with a concentration of 50%.…”

Pegagan (Centella asiatica (L.)) is one of the herbaceous plants that grow, and flowers throughout the year. Pegagan has been used for hundreds of years, especially in the dermatology, and cosmetology industries. Pegagan (Centella asiatica (L.)) has distinctive bioactive components, namely triterpene ester glycoside compounds in the form of asiaticoside, and madecoside as well as triterpene group compounds in the form of asiatic acid, and madecasic acid. There are various extraction methods to produce the following compounds namely, conventional extraction methods, and modern extraction methods. The two methods have differences in the results obtained. Therefore, the difference in the extraction method will determine the result of the difference in the levels of a compound. So that this research was carried out on the effect of Pegagan (Centella asiatica (L.)) extraction using a comparison of the Microwave-Assisted Extraction (MAE), and Ultrasound-Assisted Extraction (UAE) methods on the total phenol content in the Pegagan (Centella asiatica (L.)) extracted. Analysis of the extracteded bioactive content was carried out by analyzing the total phenol content using the Folin-Ciocalteau reagent method and analyzing the data through the Analysis of Response Surface Design expert 11 to see the significance of the research variables. The results obtained from the study are in the form of a comparison of the optimal conditions for the total phenol content, namely, the comparison between the UAE, and MAE methods for Centella asiatica (L.). extracted with ethanol solvent which is more optimal by using the MAE method because in a short time it can produce 1130.7882 mg.

“…Adanya tekanan mekanik berupa getaran pada metode ekstraksi secara sonikasi mempengaruhi kelarutan senyawa dalam pelarut dan mengakibatkan peningkatan hasil ekstraksi. Fenomena kativasi akibat pecahnya gelembung dalam pelarut dengan adanya getaran menyebabkan senyawa yang terkandung didalamnya lebih mudah berdifusi (Utami et al, 2020).…”

Kulit biji kakao adalah bagian buah kakao yang membungkus biji kakao dan cenderung menjadi limbah industri coklat. Namun, berdasarkan hasil penelitian sebelumnya menyatakan bahwa ekstrak kulit biji kakao mengandung senyawa kimia seperti alkaloid, flavonoid, polifenol, tanin dan saponin yang berpotensi sebagai antibakteri alami. Penelitian ini bertujuan untuk mengetahui potensi ekstrak kulit biji kakao (theobroma cacao L) sebagai senyawa antibakteri terhadap Streptococcus mutans. Ekstraksi kulit biji kakao dilakukan secara sonikasi menggunakan pelarut etanol 70%. Selanjutnya, dihitung nilai rendemen ekstrak, diskrining fitokimia dan diuji aktivitas antibakterinya dengan metode sumuran. Nilai rendemen dari ekstrak etanol 70% kulit biji kakao dapat dikatakan baik, yaitu 11,08% atau lebih dari 10%. Ekstrak etanol 70% kulit biji kakao teridentifikasi mengandung senyawa alkaloid, flavonoid, polifenol, tanin dan saponin. Hasil uji antibakteri menunjukkan ekstrak kulit biji kakao memiliki rata-rata zona hambat sebesar 8,44 ± 1,53 mm. Berdasarkan hasil tersebut, ekstrak etanol 70% kulit biji kakao hasil ekstraksi sonikasi berpotensi dalam menghambat pertumbuhan Streptococcus mutans.

“…In both UAE methods, as much as 250 grams were put into a glass beaker plus 2500 mL 70% ethanol solvent, then stirred until mixed and then covered with aluminium foil so that the solvent did not evaporate put into the UAE tool. Extraction was carried out within 60 minutes at 30C with an extract: solvent ratio of 1:10 ( Utami et al, 2020). Filtrate of the MAE and UAE methods were concentrated using a rotary evaporator to obtain a thick extract.…”

Papaya seeds extract was produced by the maceration method has been shown to have antibacterial activity against S. aureus, P. aeruginous, S. thypi, and E. coli. This study aims to compare the antibacterial activity of papaya seeds ethanol extract obtained using the Microwave Assisted Extraction (MAE) and Ultrasound-Assisted Extraction (UAE) extraction methods on the growth of Staphylococcus aureus bacteria. Papaya seed was extracted using MAE and UAE extraction methods using 70% ethanol as a solvent in concentrations of 20%, 40%, 60%, and 80%. The antibacterial activity test method used the disk diffusion method. The parameter observed was DDH (Diameter of Inhibitory Area) which was statistically analyzed using Two Way Anova at a 95% confidence level. The results showed that the papaya seeds ethanol extract produced from the MAE and UAE extraction methods forming significantly different had antibacterial activity against Staphylococcus aureus in all concentration series. UAE method is recommended use.This is an open access article under the CC-BY-SA license.
