Effectiveness of health promotion in increasing community knowledge, attitudes, and practices for the prevention of dengue hemorrhagic fever through the use of lemongrass leaves in bath water

Abstract

Dengue Hemorrhagic Fever (DHF) is an acute disease caused by the dengue virus and transmitted by the Aedes aegypti mosquito. This study aims to analyze the effect of health promotion on increasing community knowledge, attitudes, and practices in preventing DHF through the use of lemongrass leaves in bath water. The method used is quasi-experimental with a one-group pre-test and post-test design. The sample consists of community members in Pacarkeling Village, Tambaksari District, Surabaya City. The results show a significant increase in community knowledge, attitudes, and practices after the health promotion intervention. This increase indicates that the applied health promotion model is effective in raising awareness and preventive actions against DHF. Therefore, the results of this study can serve as a basis for developing more effective health promotion programs utilizing locally known natural materials.
