Abstract

Controlling Aedes Sp larvae is an essential component in the Integrated Mosquito Management (IMM) program because when mosquitoes are removed before they become adults, there will be no transmission of vector-borne diseases, especially DHF. However, physical, chemical, and biological control is still not optimal because it is considered resistant, less sensitive, effective, and efficient, especially in scarce clean water. The research aims to make and test the effectiveness of the innovative portable Aedes Sp larvae sucker using the electric-mechanical method. This type of research is an actual experiment in the laboratory test stage and quasi-experimental in the field test. This innovation is a pump with a suction power of 1400 litres/hour and 1800 litres/hour equipped with an AC electric motor connected to an inverter circuit. On the laboratory scale, it was tested on 1,500 instars III and IV Aedes aegypti larvae, and on a field scale, it was tested on 45 containers in Endemic Village, Klaten Regency. Data analysis used the Pearson Correlation, independent sample, and Cochran tests. Laboratory test results showed that the time to catch all Aedes Sp larvae in containers with a volume of 80 litres and 90 litres using a power of 1400 litres/hour took 60 seconds and 138 seconds, while with a power of 1800 litres/hour, it took 33 seconds and 110 seconds. The speed of the number of Aedes Sp larvae caught is affected by the volume of water >=20 litres with a water level of > 8 cm. This tool was tested in the community at 43 houses and 45 positive larvae containers. The result show that with a power of 1800 litres/second, the time needed to suck the larvae in a bathtub-type container with a volume of 80-85 litres is 122.14 seconds, while a container with a volume of 86-90 litres is 208.67 seconds. A crock-type container with a volume of 80-85 litres takes 87.80 seconds, while a volume of 86-90 litres takes 98 seconds. This tool can reduce the presence of larvae at home from 61.43% to 3.77% and the density of larvae in containers from 38.14% to 5.56%. This means that this tool is declared effective, efficient, and sensitive in reducing the density of Aedes Sp larvae compared to physical methods.
