Abstract

Corn is one of the cereals that has strategic and economic value and has the opportunity to be developed. The attack of the Sitophilus Zeamais Motsch species becomes one of the obstacles in the process of storing corn. This study aims to develop the potential of plant biopesticides from grinting grass to control the warehouse pests of Sitophilus Zeamais Motsch. This research is a laboratory based experimental study. The independent variables in this study were the gram weight of grinting grass extract and the number of Sitophilus Zeamais Motsch pests. The dependent variable in this study was the mortality of Sitophilus Zeamais Motsch. Grinting grass extract is obtained using maceration method. Qualitative and quantitative tests were carried out to test the active compound content of grinting grass. Vegetable biopesticide toxicity tests were carried out using a completely randomized design. The results showed that variations in the weight of grinting grass affect the content of chemical compounds present in the grass. Based on UV-Vis and FTIR spectra, the content of polyphenols, alkaloids, flavonoids, terpenoids, steroids, and saponins contains 20 gr / 100 mL, there are flavonoids as much, 2.38 mg / mL, saponins as 2.04 mg / mL, alkaloids as much as 1.79 mg / mL, polyphenols 3.15 mg / mL, steroids as much as 2.24 mg / mL and terpenoids as much as 3.15 mg / mL. Based on qualitative tests the active compound is evidenced by changes in color and deposition. While based on pest mortality tests, it was found that almost 50 percent of grinting grass extract can kill corn pests within a period of 7 days of observation with an extract concentration of 800 ppm.

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
