Abstract


Dengue Hemmoragic Fever (DHF) is one of the public health problems in Indonesia. The disease is caused by dengue virus that is transmitted to humans through the bite of Aedes aegypti mosquito. Aedes aegypti mosquito eggs usually live in clean water puddles. The factors that affect the viability of Aedes aegypti mosquito eggs are water pH and egg structure. Alum can decrease the pH of water and chlorine can damage the egg protein structure. Both chemicals are used as water purifiers. The purpose of this research is to analyze the difference between 100 ppm alum water concentration and 10 ppm chlorine concentration to Aedes aegypti mosquito egg hatchability. The research was carried out by experimental method. The research was done with 3 treatments, those were 100 ppm alum water concentration, chlorine 10 ppm concentration, and 1 control. At each concentration were given 25 Aedes aegypti mosquito eggs. The reseach was conducted for 3 days and done throught 3 studies in parallel. The result showed that the chlorine water concentration 10 ppm concentration was more effective in inhibiting  the hatching of Aedes aegypti mosquito eggs compared with 100 ppm alum water concentration. The data of the research were analyzed using Kruskal-Wallis test which showed the value of p <0,05 which stated that there is difference of the hatchability of Aedes aegypti mosquito egg. Based on this research it can be concluded that 10 ppm chlorine water concentration was more effective in inhibiting the hatchability of Aedes aegypi mosquito eggs, so chlorine can be used to decrease the density of Aedes aegypti mosquito.
