Abstract

Background: The COVID-19 outbreak has changed how people live worldwide, making hand hygiene a must, whether it involves hand sanitizer (HS). The majority of HS are made of alcohol. Several side effects of alcohol are dryness and allergies. Alternative natural ingredients and HS are needed. Red betel (Piper crocatum) and white galangal (Alpinia galanga) are familiar and easy to be found. These two plants have the potential to be the composition of HS because of their compounds, such as antioxidants, antibiotics, antifungals, and antivirals. However, there is a need for further research on their formulation and effectiveness in germ-killing.Purpose: To formulate and identify the antibacterial activity of HS containing red betel and white galangal extract.Method:  This research was an in vitro laboratory experiment with several steps, including extraction, specific and nonspecific tests, formulation, and antibacterial activity tests.Results: Red betel and white galangal leaves had been extracted at a concentration of 10% and formulated into HS. The HS containing 10% red betel extract produced an inhibition zone of 0 mm against E. coli and 1.05 mm against S. aureus, and the HS containing 10% White galangal extract produced an inhibition zone of 1.47 mm against E. coli and 1.40 mm against S. aureus.Conclusion:  The formulation of HS containing 10% of white galangal extract is more effective than the HS containing 10% of Red betel extract.

Abstract

Background: Natural disasters pose significant risks to vulnerable populations, particularly pregnant, postpartum, and breastfeeding women, who face increased health and safety challenges during emergencies. Strengthening disaster preparedness through accessible educational strategies is essential to improve resilience and reduce adverse outcomes. Objective: This study aimed to develop and evaluate an Android-based application as an educational tool to enhance disaster preparedness among maternal populations. Methods: This study employed a Research and Development (R&D) approach based on the Borg and Gall model, followed by feasibility and effectiveness evaluation. Data were collected through interviews, validation assessments, and structured questionnaires. The application was tested among pregnant, postpartum, and breastfeeding women using a pretest–posttest design to assess changes in disaster preparedness knowledge. Results: The developed application, named “Ibu Siaga Bencana,” demonstrated high content and media validity. Preliminary testing showed good usability and practicality. Effectiveness evaluation indicated a 40% increase in participants' disaster preparedness knowledge following application use, suggesting a substantial improvement in understanding. Conclusion: The application is a feasible and effective educational tool for improving disaster preparedness among maternal populations. Further studies with larger samples and more rigorous designs are needed to confirm its effectiveness and long-term impact.
