“…This means that the larvae experience toxic effects that impact energy depletion. This state is in line with the chemical mechanisms of the largest lemongrass plants, such as citronellal and geraniol Toxic compounds contained in Citronella (Cymbopogon nardus L) are an active substance that is harmful to iron fat when in contact with the respiratory system of larvae [13]. Acute poisoning such as seizures, disorders of the central nervous system, and respiratory paralysis is a function of Citronella Citronella in Citronella which works by inhibiting the enzyme acetylcholinesterase, so that acetylcholine accumulation occurs, which results in death in insects [12,13,15].…”

“…Larvicide is the best method of controlling the Aedes aegypti mosquito population. The action of larvicides as ectoparasiticides is by inhibiting the action of the acetylcholinesterase enzyme, which can later cause larval death [13]. Essential oils (ester) produced by lemongrass plants contain compounds such as citral, geraniol, citronellal, eugenol-methyl ether, dipentene, eugenol, kadinen, kadinol, and limonene.…”

Dengue Hemorrhagic Fever (DHF) is a disease caused by ectoparasites. The ectoparasite in this disease is the Aedes aegypti mosquito which acts as a vector. Aedes aegypti is a type of mosquito that can carry the dengue virus that causes dengue fever. The symptoms of this disease are rarely noticed and can spread quickly. In addition, this disease also attacks all ages and can cause death. Cymbopogon nardus (L.) Rendle is an aromatic grass from the Poaceae family that produces essential oil mainly in the leaves. The essential oil from C. nardus is known as citronella oil has repellent activity. To determine the effect of citronella powder (Cymbopogon nardus) as activated charcoal packaged in bags for controlling Aedes aegypti in bathroom tubs. This study is an experimental posttest-only control group design consisting of a control group and a treatment group using activated charcoal from lemongrass at a concentration of 1%, 2%, and 2.5%, which was treated on Aedes aegypti mosquito larvae instar III five times test. Data analysis used the One-way Anova Statistical Product and Solutions (SPSS) Version 26 test. The results showed the effect of citronella powder (Cymbopogon nardus) as activated charcoal on the mortality of the third instar Aedes aegypti mosquito larvae. This is indicated by the p-value of 0.197. The high concentration of activated charcoal from lemongrass powder determines the high mortality of third instar Aedes aegypti larvae. This is indicated by the significant difference between the concentration treatments. For further research, an increase in the concentration of activated charcoal is needed to increase larval mortality.

“…Sedangkan perbandingan antara konsentrasi uji 5% dengan 10%, 10% dengan 15%, dan 5% dengan 15%, dapat disimpulkan bahwa tidak ada perbedaaan yang bermakna (p ≥ 0,05) atau dapat dikatakan kedua konsentrasi tersebut memiliki daya bunuh yang sama. 17 Pada akhir penelitian yaitu jam ke-24, uji analisis probit diketahui LC50 dan LC90 secara berturut-turut adalah 11,01% dan 22,80% (Tabel 5). Hasil tersebut berarti dibutuhkan konsentrasi sebesar 11,01% untuk membunuh setengah populasi larva pada jam ke-24 dan 22,80% untuk membunuh 90% larva pada jam ke-24.…”

Aedes aegypti and Aedes albopictus are known as the two main vectors of DHF disease. One way to control DHF is by breaking the chain of spread in the larval phase with larvicides. The use of organic larvicides derived from plants is in great demand, one of which is extracts of lemongrass (Cymbopogon citratus). This study aims to determine the level of efficacy or the effect of concentration of lemongrass extract solution on mortality rates of Aedes sp. larvae. This is an experimental study using 40 instar larvae III / IV of Aedes sp. which were given the intervention of lemongrass plant extracts with a concentration of 5%, 10%, 15%, and 20%. This experiment was carried out twice. Four observations were made every 6 hours. Probit analysis was performed to determine Lethal Concentration (LC50 and LC90) and Lethal Time (LT50 and LT90). The analysis showed that the lemongrass plant extract at a concentration of 20% had a significant difference with the concentration of 5%, 10%, 15%, and the control group (p <0.05). In conclusion, extract of lemongrass (Cymbopogon citratus) with a concentration of 20% is effective for killing larvae of Aedes sp.Keywords: Aedes sp., Cymbopogon citratus, larval mortality Abstrak: Nyamuk Aedes aegypti dan Aedes albopictus diketahui sebagai dua vektor utama dari penyakit DBD. Salah satu cara pengendalian DBD adalah dengan memutus rantai penyebaran pada fase larva dengan larvasida. Pemanfaatan larvasida organik atau alami yang berasal dari tumbuh-tumbuhan banyak diminati, salah satunya adalah ekstrak tanaman serai (Cymbopogon citratus). Penelitian ini bertujuan mengetahui tingkat keampuhan atau pengaruh konsentrasi larutan ekstrak tanaman serai terhadap tingkat mortalitas larva nyamuk Aedessp. Penelitian ini bersifat eksperimental sederhana menggunakan 40 ekor larva instar III/IV nyamuk Aedes sp. yang diberikan intervensi ekstrak tanaman serai dengan konsentrasi 5%, 10%, 15%, dan 20%. Pengamatan dilakukan setiap 6 jam sebanyak 4 kali, dengan 2 kali percobaan. Analisis probit dilakukan untuk mengetahui Lethal Concentration (LC50 dan LC90) dan Lethal Time (LT50dan LT90). Hasil analisis menunjukkan bahwa ekstrak tanaman serai pada konsentrasi 20% memiliki perbedaan signifikan dengan konsentrasi 5%, 10%, 15%, dan kelompok kontrol (p < 0,05). Simpulan penelitian ialah ekstrak tanaman serai dengan konsentrasi 20% efektif untuk mematikan larva Aedes sp.Kata Kunci: Aedes sp., Cymbopogon citratus, mortalitas larva

Aedes aegypti L. Mosquito is the only vector of Dengue Hemorrhagic Fever (DHF). The chemical-based control agents have a negative effect if used for a long time. Therefore, this research focused on finding the natural agent that may act as an adulticide, like Bintaro (Cerbera manghas L.). Bintaro leaves contain active compounds such as cerberin (one of the alkaloids), flavonoids, tannins, steroids, and saponins that have a mortality effect on mosquitoes. The study was to determine the effectiveness of Bintaro leaves extract as an adulticide against Aedes aegypti mosquitoes. This experimental research uses the posttest-only control group design and uses Ae. Aegypti mosquito aged 3-5 days as the sample. There were seven different concentrations of Bintaro leaves extract as a treatment, namely 300 ppm, 350 ppm, 400 ppm, 450 ppm, 500 ppm, 550 ppm, and 600 ppm. The method used in this research is using a 250 ml Duran bottle. The results of the study showed that the Bintaro leaves extract at a concentration of 600 ppm was more effective against the mortality of Ae. Aegypti, but not significantly different from the 400 ppm, 450 ppm, 500 ppm, and 550 ppm treatments. And the LC50 probit regression analysis was 455.602 ppm, and the LC90 value was 1735.956 ppm.
