Abstract

Dengue fever (DHF) remains a public health challenge in Indonesia, particularly in forest areas where disease vectors like Aedes spp. mosquitoes pose risks. The Kawasan Hutan Dengan Tujuan Khusus (KHDTK) of Diponegoro University, including Kalongan and Mluweh Villages, has potential as a DHF vector habitat, making risk factor analysis crucial for dengue disease control. This study aimed to analyze the risk factors for DHF in Kalongan and Mluweh Villages. This cross-sectional study analyzed DHF risk factors among 200 respondents (150 in Kalongan and 50 in Mluweh). Data were collected through questionnaires, mosquito larvae inspection (PJN), and species identification. Bivariate analysis was used to examine the relationship between education and knowledge levels and attitudes toward DHF prevention. The larvae identification results showed that Aedes aegypti (53.3%), Aedes albopictus (45.3%), and Culex (1.3%) larvae were found in Kalongan Village. In Mluweh Village, Aedes aegypti (53.3%), Aedes albopictus (37.8%), and Culex (8.9%) larvae were found. Bivariate analysis showed a significant relationship between education level (p = 0.024) and knowledge level (p = 0.001) and attitudes toward DHF prevention. These findings provide insights into the risk factors for DHF in forested areas and support targeted vector control and community-based prevention strategies.
