MATHEMATICS MODEL: DOMINANT FACTORS OF DENGUE HEMORRHAGIC FEVER DISEASE

Abstract

Dengue hemorrhagic fever (DHF) is a disease caused by an arbovirus that enters the human body through the Aedes aegypti or Aedes albopictus mosquito. The spread of dengue fever globally has tended to be higher in the last 50 years, including in Indonesia and Kalimantan, especially the Banjarbaru area. This is a motivation to develop ideas for systematic prevention by involving mathematical models with aquatic and physical factors in the model. Aquatic factors affect water temperature, water pH, COD (Chemical Oxygen Demand), BOD (Biological Oxygen Demand), and DO (Dissolved oxygen). The physical factors include air temperature and humidity. Next, statistical analysis was carried out through correlation and regression analysis involving these factors. This paper aims to determine the most dominant factors in mosquito larvae growth. The water temperature, COD and DO factors were obtained, which were then used in the SIRD-ASI mathematical model in the aquatic compartment. The data collection methodology uses an implicit purposive sampling technique. This method selects samples representing a population by taking primary samples from community locations affected by dengue fever. This preliminary data is essential in forming models, mainly aquatic compartments. Using this model, it is hoped to provide a picture that best suits the existing dengue problem and produce appropriate solutions to prevent the spread of dengue fever by involving aquatic factors.
