Infectious diseases are conditions that can be brought on by a variety of different organisms, including bacteria, viruses, fungi, and parasites. Typhoid fever is an example of an infectious disease that frequently causes the body's defenses to come under attack. The fever associated with typhoid is a leading cause of death around the world. Infection with the bacterium Salmonella typhi is considered to be one of the potential causes of typhoid fever. When antibiotics are used to treat bacterial infections, there is a risk that the bacteria will become resistant to the medication. In day-to-day life, basil leaves are utilized both as a cooked vegetable and as a fresh vegetable. The antibacterial properties of kemangi leaves have yet to be fully uncovered. The purpose of this study was to investigate the various mechanisms that are involved in antibacterial activity. These mechanisms include cell leakage, minimum inhibitory concentration, minimum killing concentration, and antibiofilm activity. The minimum inhibitory concentration (MIC) was determined with the agar diffusion method, the minimum biofilm forming concentration (MBC) was determined with the staining method, and cell leakage was determined with UV-VIS spectrophotometry at wavelengths of 260 nm (DNA) and 280 nm (protein). Additionally, the formation of anti-biofilms was determined with microtiter plates and gentian violet staining. In the moderate category, the MIC value tests showed a concentration of 0.3125% with an inhibition zone value of 6.80 0.05 mm. These results were obtained from the MIC value. Because there was no detectable bacterial growth on the streaked medium, KBM was obtained at a concentration of 10%. At wavelengths of 260 and 280 nanometers, leakage cells show absorbance absorption. The percentage of biofilm activity that is measured when the concentration is increased to 25% is 44.82%. In conclusion, the ethanol extract of basil leaves possesses a possible antibacterial mechanism against Salmonella typhi. This was discovered through testing.

Fermentation is a natural process when microorganisms such as yeast and bacteria convert carbohydrates such as starch and sugar into alcohol or acid. Some fermented products from microorganisms can be processed into foods that can be consumed and provide good health effects for the body. Fermented foods such as kefir, tempeh, natto, and kimchi are foods that produce probiotic bacteria, which are good bacteria that have a beneficial effect on the host when consumed in sufficient quantities (about 108–1011 CFU/mL). If probiotics are consumed in combination with prebiotics, they will have a synergistic effect called "synbiotics" and will increase the benefits of probiotics. Several in vitro, in vivo, and clinical studies have shown that probiotics can help with diseases like diarrhea, high cholesterol, diabetes, colon cancer, and dyslipidemia

The incidence of anemia in pregnant women carries a great risk because the fetus's need for iron and oxygen supply during development requires iron. This community service activity aims to examine and administer anemia drugs or blood boosters to pregnant women and provide education related to anemia and important nutritional intake for pregnant women to prevent risk factors for anemia. A total of 36 pregnant women patients checked themselves, with 12 in the first trimester, 15 in the second trimester, and 9 in the third trimester. A total of 7 people in the first trimester experienced anemia (19.44%), 10 people in the second trimester (27.77%), and 5 people in the third trimester (13.88%). The rest do not have anemia. This can be due to the fact that the intake of balanced nutrition and foods rich in iron is sufficient during pregnancy. Iron intake during pregnancy in the first trimester is recommended at as much as 0.8 mg/day, while in the second and third trimesters, as much as 6.3 mg/day. Thus, it is hoped that the imparted knowledge and information will be adhered to in order to limit the risk of anemia in pregnant women so that the process of pregnancy until birth will proceed without incident.
