Potensi Ekstrak Daun Nangka sebagai Biolarvasida Nyamuk Culex sp

Abstract

Mosquitoes are type of insect that acts as a disease vector. One of them is Culex sp mosquitos which their existence is many around us. In Indonesia there are still a lot of disease cases that caused by Culex sp mosquitos, one of them is filariasis disease. The efforts to control thecurrent population of Culex sp mosquitoes mostly use chemical insecticides. The control becomes difficult because of the resistance to chemical insecticides and adversely affects the environment. This study aims to determine the potential of jackfruit leaf extract as biolarvasida against Culex sp. The type of this study was post test onlycontrolled group design, using 625 larvae Culex sp instar III, divided into 5 groups (negative control group, 0.25% extract, 0.50% extract, 0.75% extract, extract and 1% extract). Observation was performed 24 hoursafter the treatment and counted the number of larvae death.The data were analyzed by Kruskal Wallis test followed by Post Hoc Mann-Whitney U test to determine the killing power of leafy leaf extractusing Probit analysis. The results of data analysis in this study were thedeath rate percentage of larvae after 24 hours treatment was 0% incontrol, 44% in 0.25%extract, 52% in0.50% extract, 60% in 0.75%extract,while in the extract group of 1%, the number of larval deaths was 72%. Itobtained results with significant differencein some treatment groups thatwere concentrations of 0.25% - 1%. Probit analysis showed that LC50 wasat 0.382% concentration.From results of the studyit can be concluded that jackfruit leaf extract(Artocarpus heterophyllus Lamk) was potential as Culex sp mosquitobiolarvacide. So it is necessary to conduct further research on the effectsof compounds that contained in other plant parts such as flowers, stemsand roots which will be expected to have a function asbiolarvasida.Keywords: Leaf Jackfruit, Biolarvasida, Mosquito Culex sp

EFFECTIVENESS OF THE LARVACIDE ETHANOL EXTRACT OF JACKFRUIT (Artocarpus heterophyllus L.) AGAINST Aedes aegypti LARVA

“…This study found that extract concentrations of 0.75%, 1%, 2%, and 3% produced larval mortality of respectively 79.2%, 83.2%, 91.2%, and 96% in 8 hours, while 1% temephos produced 100% larval mortality and negative control concentration produced 0% larval mortality. In comparison, previous research conducted by Firdaus, et al (2018) found that the fatality rate of Culex sp. larvae with the lowest average was discovered at a concentration of 0.25% (44%), and mortality at the maximum concentration was recorded at 1% concentration (72%).…”

“…The higher the yield value, the more extracts obtained and the more desired analytes. In comparison between previous studies by Firdaus, et al (2018), the yield of ethanol extract of jackfruit leaves using ethanol solvent and using the maceration method had different results of 10.58%, while the yield of ethanol extract of jackfruit leaves using the percolation method was 24.3%. Simplicia may affect the amount of extract produced.…”

“…At 4% concentration, it may damage or eradicate Culex sp larvae after 24 hours of treatment. Substances that are found in jackfruit leaves are including tannins (3.08%), flavonoids (0.92%), and saponins (1.36% ) (Firdaus, et al, 2018).…”

Inhibitory activity of jackfruit (Atrocarpus heterophyllus Lam.) leaf extract on the growth of Porphyromonas gingivalis bacteria

“…Besides being used as an alternative medicine for several diseases, such as fever, boils, skin diseases, and anti-diarrhea, jackfruit leaves are known to be used as an antibacterial, analgesic and immunomodulator. The antibacterial properties of jackfruit leaves are obtained from the active compounds contained in jackfruit leaves, namely, tannins, flavonoids, and saponins [7,8]. Tannin is the active compound with the most content in jackfruit leaves.…”

“…Jackfruit leaves are useful in the treatment of fever, ulcers, skin diseases, antidiarrheal, analgesic and immunomodulatory. Jackfruit leaves are known to contain saponin (1.36%), flavonoid (0.92%) and tannin (3.08%) which act as antibacterial compounds [7,8].…”
