<p>The <em>Aedes aegypti</em> mosquito can develop an immune system against the insecticide used. Control efforts with the use of insecticides are no longer effective if the target insects have become resistant. So there needs to be an effort to overcome the insect resistance that is targeted. Citronella grass is an herbal plant that can be used as an ingredient in vegetable pesticides. The leaves and stems are distilled to produce essential oil known as citronella oil. This research is about studying the effects of citronella oil against the resistance of the vector carrier for dengue fever, namely <em>Aedes aegypti. </em>The detection of citronella essential oil (<em>Cymbopogon nardus</em> L.) by Thin Layer Chromatography showed a reduction in UV<sub>254</sub> visualization (Rf 0,68). The resistance test showed that the mortality percentage of adult mosquitoes <em>Aedes aegypti</em> exposed to 0.03% alphacymethrin was 73,7% resistant criteria (&lt;90%). The mortality percentage of adult mosquitoes <em>Aedes aegypti</em> exposed to Alphacypermethrin (0,03%) and citronella oil was 2,5% each; 5%; 7,5% and 10% with treatment time 15 respectively, namely 18,7%, 50,7%, 70,7% and 82,7%; the treatment time of 30 minutes consecutively is 62,7%, 89,3%, 96% and 97,3% and the treatment time is 60 minutes respectively, namely 93,3%, 98,7%, 98,7% and 100%. There was an increase in the percentage of mosquito deaths exposed to the combination of alphacypermethrin and citronella oil, compared to those without citronella oil, this indicates that mosquitoes are more susceptible and resistance has decreased due to exposure to citronella oil. <strong></strong></p>

Lemongrass (Cymbopogon nardus L.) is an economically valuable plant that produces citronella oil and could grow on marginal lands. This study aimed to analyze citronella oil yields planted with agroforestry and monoculture patterns in a post-mining revegetation area. The treatment consisted of 3 factors, namely planting pattern, fertilizer dosage, and plant spacing. The measured variable was the citronella oil yield. The study was conducted by planting two lemongrass varieties i.e., Sitrona 2 Agribun Variety dan G2 Variety in the agroforestry and monoculture areas. The study was conducted for 12 months with three harvest times, i.e., in the 6th, 9th, and 12th months. The results showed that planting patterns significantly affected the citronella oil yield. Planting pattern of Monoculture-Sitrona 2 Agribun Variety (P4) produced the highest oil yield (1,95%). Plant spacing and dosage of bokashi fertilizer did not significantly affect the citronella oil yield. The Monoculture-Sitrona 2 Agribun Variety (P4) significantly increased the oil yield compared to the Agroforestry- Sitrona 2 Agribun Variety (P2), Monoculture-G2 Variety (P3), and Agroforestry-G2 Variety (P1) with a respective oil yield of 1,95% (P4), 1,50% (P2), 1,01% (P3), and 0,99% (P1). Sitrona 2 Agribun Variety tended to produce a higher oil yield than the G2 Variety.  Keywords: agroforestry, citronella oil, lemongrass, oil yield, revegetation

Culex Sp

Nyamuk Culex sp. merupakan vektor filariasis. Upaya pencegahannya adalah dengan mengendalikan keberadaan nyamuk Culex sp. Serai wangi diketahui memiliki kandungan senyawa metabolit sekunder yang bermanfaat sebagai insektisida nabati. Penelitian ini dilakukan untukmengetahui daya toksisitas ekstrak etanolik daun serai wangi terhadap mortalitas larva Culex sp. instar III.Metode penelitian yang digunakan adalah metode eksperimental dengan desain penelitian rancangan acak lengkap (RAL), perlakuan yang diujikan berupa kontrol reagen; kontrol negatif; 250 ppm;353 ppm; 498 ppm; 702 ppm; 991 ppm; 1397 ppm; 1970 ppm, masing-masing diulangtiga kali. Variabel yang diamati adalah mortalitas larva pada berbagai konsentrasi. Mortalitas larva dihitung setelah 24 jam. Data yang diperoleh dianalisis menggunakan uji kruskal wallis dan uji man whitney dengan aplikasi SPSS 21 serta untuk menentukan nilai LC50 menggunakan analisis probit. Hasil penelitian menunjukkan bahwa ekstrak etanolik daun serai wangi berfungsi sebagai larvasida terhadap larva Culex sp. instar III. Semakin tinggi konsentrasi ekstrak daun serai wangi yang digunakan maka semakin besar persentase mortalitas larva Culex sp. instar III. Hasil penelitian menunjukkan bahwa konsentrasi 991 ppm merupakan konsentrasi paling efektif dan nilai LC50 adalah 1036,54 ppm. Kesimpulan penelitian ini adalah ekstak etanolik daun serai wangi (Cymbopogon nardus L.) memiliki aktivitas sebagai larvasida terhadap larva Culex sp. instar III.

Minyak serai wangi merupakan salah satu komoditas atsiri yang memiliki prospek yang cukup besar diantara minyak atsiri lainnya, selain manfaatnya sebagai produk minyak atsiri atau biasa dikenal dengan citronella oil juga mempunyai kegunaan sebagai vegetasi konservasi yang berpotensi mencegah terjadinya erosi tanah dan merehabilitasi lahan kritis. Penelitian ini bertujuan untuk mengetahui persentase rendemen minyak atsiri dan untuk mengetahui hasil rendemen pada ketiga jenis dalam mencapai rendemen yang sesuai standar Nasional Indonesia (SNI). Rancangan yang digunakan dalam penelitian ini adalah rancangan acak kelompok (RAK) 1 faktor dimana 3 perlakuan varietas yang berbeda yaitu varietas Lenabatu, Mahapengiri Klon G1 dan Mahapengiri G2. Varietas yang memiliki tinggi tanaman yang tertinggi adalah Lenabatu, namun jumlah anakan yang terbanyak dimiliki oleh Mahapengiri klon G2. Bobot basah, bobot seluruh tanaman dan bobot kering tidak terlihat adanya perbedaan diantara ketiga kultivar. penelitian menunjukan analisis rendemen tertinggi pada ketiga jenis serai wangi sesuai SNI yaitu varietas Mahapengiri Klon G2 sebesar 0,92 %., diukur berdasarkan parameter pengamatan berupa tinggi tanaman, jumlah anakan, bobot basah, bobot kering serta bobot seluruh tanaman, adapun sifat kimia tanah berupa c-organik dan jaringan tanaman berupa NPK, Mg faktor tersebut mampu meningkatkan sejauh mana pertumbuhan serai wangi. Faktor lokasi, aspek budidaya, iklim, dan varietas menjadi aspek penting dalam meningkatkan kualitas minyak atsiri serai wangi.
