Abstract

Bacterial infections, especially those caused by Staphylococcus aureus, are a serious global health problem. This bacterium can cause a range of diseases, from mild skin infections to potentially fatal sepsis. It has also been reported to have developed resistance to antibiotics, which highlights the need for developing natural antibiotics with minimal side effects. The Duwet plant (Syzygium cumini L.), particularly its bark, is traditionally used to treat dysentery, diarrhea, and dyspepsia, and contains numerous bioactive compounds. Due to these benefits and its compounds, the bark of the duwet tree has the potential to possess beneficial antibacterial properties. The purpose of this study was to determine the extent to which the ethanol extract of duwet bark can inhibit the growth of Staphylococcus aureus in a laboratory setting (in vitro). The methods used included an extraction process where the duwet bark was soaked in 96% ethanol, followed by a phytochemical test to determine its chemical content. The extract was then tested for its ability to inhibit the growth of Staphylococcus aureus using the well diffusion method at concentrations of 20%, 40%, and 60%. The results showed that the duwet bark extract had the strongest antibacterial activity at a concentration of 60%, with an inhibition zone of 10.67 ± 2.25 mm, which falls into the moderate category.

Abstract

Health problems in school-age children continue to be a major concern due to their impact on health quality and future development. Pediculosis capitis (head lice infestation) is a frequently encountered issue, strongly associated with inadequate personal hygiene, especially hair care. This condition, common in early childhood, causes intense itching, discomfort, and interferes with learning. Therefore, preventive measures through health education and direct screening are needed. This community service initiative aimed to improve students' knowledge of pediculosis capitis and identify infestation rates among students at Kusuma Mulya 12 Kindergarten, Sendang Village, Banyakan District, Kediri Regency. Methods included educational lectures, discussions, demonstrations, and direct scalp examinations. Evaluation utilized pretests and posttests to measure knowledge change, alongside visual inspection to determine infestation prevalence. Conducted in May 2024 with 50 students, the activity revealed low baseline knowledge. Post-intervention, a significant knowledge increase was achieved (95% posttest score). Screening identified a 36% infestation rate. In conclusion, combined education and examination effectively improved knowledge and enabled early detection of head lice. This program is expected to promote early adoption of clean and healthy living habits.
