Abstract

Dengue Hemorrhagic Fever (DHF) is a disease caused by a virus through the intermediary Aedes aegypti mosquito. This disease spreads throughout the world and endangers and threatens human survival. Efforts to control vectors using synthetic larvicides commonly used are still less effective and inadequate. The purpose of this study was to determine the optimum concentration of Moringa leaf extract for larvicidal activity. Moringa leaf extract was macerated with ethanol, then the extract was carried out by larvacide testing. Variations in concentration in the larvicide test were 1000ppm, 2000 ppm, 3000 ppm, 4000 ppm and 5000 ppm. The results showed that Moringa leaf extract can kill larvae at concentrations of 1000 and 2000 ppm with a 6hour death time. At a concentration of 3000 ppm the extract can kill larvae with a 4-hour death time. At concentrations of 4000 ppm and 5000 ppm it can be killed in two hours of death. Based on the results of the study it can be concluded that at a concentration of 5000 ppm Moringa leaf extract is the best concentration for larvae of Aedes aegypti.

Abstract

Dengue Hemorrhagic Fever (DHF) is a disease caused by Dengue virus. The disease is spread rapidly in the territory of Indonesia by Aedes aegypti mosquito as the vector. Using Moringa Aloifera leaf extract as a natural larvacide is an attempt to control the disease. This study aims to determine the effect of Moringa Aloifera leaf extract on the mortality of Aedes aegypti larvae. Moringa Aloifera leaf extract is obtained by maceration. The experimental design was divided into negative control groups containing aquades, positive controls containing abate and sample treatment groups. Phytochemical test and UV-Vis spectroscopic quantitative test to identify active compounds. A total of 20 Aedes aegypti larvae were put into a glass containing a solution of distilled water, abate solution and sample solution. Observations are made every 2 hours for 24 hours. The results showed that Moringa leaf extract solution could kill larvae at LC50 3953.17 ppm and LT50 18.98 hours. The mortality rates of larvae at each concentration were 1000 ppm, 5.25 units / 2 hours; 2000ppm, 5.28 units / 2 hours; 3000ppm, 5.91 units / 2 hours; 4000 ppm, 7.18 units / 2 hours, and 5000 ppm 8.63 units / 2 hours. The results showed that Moringa Aloifera leaf extract can kill Aedes aegypti larvae because they contain alkaloids, tannins and flavonoids.Keywords: larvacide, Moringa, Aedes aegypti larvae

Abstract

The purpose of the IoT-based uv sterilizer design that uses the NODEMCU ESP32 as a microcontroller is to utilize digitalization technology that can be used to help the medical team at Blambangan Hospital in terms of room UV sterilization, because the hospital still uses manual control. UV rays have a very dangerous radiation effect if exposed to humans directly, so it is necessary to design a control device that can help the medical team avoid UV radiation. In this study using NODEMCU as a data receiver that has been integrated into the UV sterilizer user room network and uses an application on android as a remote control.
