Abstract

Staphylococcus aureus is one of the causes of infectious disease, ranging from mild to severe infections such as meningitis. The drug that is often used is the penicillin class of antibiotics. Apart from chemical antibiotics, natural antibacterial compunds from plants can be also used as an alternative treatment for this infection. Such as green betel (Piper betle L.) and legundi (Vitex trifolia L.). The ethanol extract of betel leaf has antibacterial activity against Staphylococcus aureus. The phytochemical content in legundi leaf is also able to inhibit the growth of Staphylococcus aureus. The ethanol extract of betel leaf and legundi is made through a maceration process. The extract concentrations used in this study were 20%, 30%, and 40%. The inhibition test of Staphylococcus aureus using the disc method. From the results of this study, the active substances found in betel leaf were flavonoids, tannins, and phenols, while in legundi were found flavonoids, tannins and phenols, and quinones. In total, the mean inhibition zone in this study ranged from 7.87mm to 17.33mm where legundi leaf extract was in the moderate category, betel and combination extract were classified as strong. There was a difference in the diameter of the inhibition zone of betel and legundi extract at a concentration 20% with 40%. In the combination extract there is a difference in the concentration of 20% with 40% and 30% with 40%. An antimicrobial compound can be said to synergize if a mixture of two or more antimicrobial compounds is able to provide an effect of each compounds. In this study, it has seen that the mean of the combination is higher than the mean of legundi leaf extract. Meanwhile, the mean of betel leaf extract is still greater than the combination extract.

Abstract

Anemia is characterized by low Hemoglobin (Hb) levels, which is a major health problem affecting adolescent girls, with a prevalence that remains relatively high. Anemia in adolescent girls is largely caused by increased iron requirements during puberty and blood loss during menstruation. Untreated anemia can continue into pregnancy and affect the health of both mother and child. This activity aimed to educate and screen 40 female students at SMP Negeri 11 Denpasar for anemia. The methods used include health education through interactive counseling, Hb level screening using photometry, the formation of adolescent health cadres and data analysis using statistical tests to determine the increase in knowledge. The screening results showed that 9 participants had symptoms of anemia with Hb <12 g/dL. The counseling session successfully increased the participant’s knowledge significantly, with the average post-test score jumping from 56 to 76 compared to the pre-test results. Although the educational intervention proved to be effective in increasing knowledge about anemia, the importance of follow-up medical treatment and continuous monitoring is very much needed. This activity successfully increased adolescent girls’ knowledge about anemia. However, follow-up in the form of iron tablets and dietary changes is required. Continuous intervention with the involvement of families and schools is expected to reduce the prevalence of anemia and improve the health quality of adolescent girls in the area.
