Kata Kunci: Insektisida Alami, Ekstrak Kulit Bawang Putih, Aedes aegypti L.
Aedes aegypti L. merupakan vektor utama penyebab penyakit DBD. Upaya
pengendalian penyebaran larva Aedes aegypti L. saat ini dilakukan dengan
menggunakan insektisida kimia yang memiliki banyak dampak negatif, sehingga
diperlukan insektisida alami yang lebih ramah lingkungan. Ekstrak Kulit bawang putih
berpotensi sebagai insektisida alami karena mengandung senyawa alkaloid, polifenol,
tanin, flavonoid, saponin dan triterpenoid. Penelitian ini bertujuan untuk mengetahui
efektivitas ekstrak kulit bawang putih terhadap mortalitas larva, LC50 ekstrak kulit
bawang putih dan tingkah laku larva Aedes aegypti L. setelah diberikan beberapa
perlakuan. Penelitian ini menggunakan metode eksperimental, desain Rancangan
Acak Lengkap (RAL) dengan 6 perlakuan yaitu K- (100 ml air sumur), K+ (abate 100
ppm), P1 (8.000 ppm), P2 (12.000 ppm), P3 (16.000 ppm), P4 (20.000 ppm) dan
masing-masing 4 ulangan. Analisis data dilakukan menggunakan analisis varian
(ANAVA) serta uji lanjut berupa Uji Jarak Nyata Duncan (JNTD) dan analisis regresi
probit. Hasil uji analisis varian (ANAVA) menujukkan bahwa Fhitung > Ftabel = 190,50
> 2,77 pada á = 0,05. Simpulan penelitian ini adalah pemberian ekstrak kulit bawang
putih berpengaruh terhadap mortalitas larva Aedes aegypti L. sehingga ekstrak kulit
bawang putih berpotensi digunakan sebagai insektisida alami, LC50 ekstrak kulit
bawang putih yang dapat mematikan 50% larva Aedes aegypti L. berdasarkan uji
analisis regresi probit adalah pada konsentrasi 12.000 ppm, ekstrak kulit bawang putih
menyebabkan perubahan tingkah laku pada larva Aedes aegypti L.

Alfisyahrina. 2022. Effectiveness of Garlic (Allium sativum) peel waste extract L.) As a Natural Insecticide Against Aedes Aegypti L. Thesis, Department of Biology Education, Faculty of Teacher Training and Education, Syiah Kuala University. Supervisor: (1) Drs. Supriatno, M.Sc., Ph.D (2) Dr. Hafnati Rahmatan, M.Si Keywords: Natural Insecticide, Garlic Skin Extract, Aedes aegypti L. Aedes aegypti L. is the main vector that causes dengue fever. Effort Control of the spread of Aedes aegypti L. larvae is currently carried out by using chemical insecticides which have many negative impacts, so that Natural insecticides that are more environmentally friendly are needed. Garlic peel extract potential as a natural insecticide because it contains alkaloids, polyphenols, tannins, flavonoids, saponins and triterpenoids. This study aims to determine effectiveness of garlic peel extract on larval mortality, LC50 peel extract garlic and the behavior of Aedes aegypti L. larvae after being given some treatment. This study uses an experimental method, the Design Design Completely Randomized (CRD) with 6 treatments, namely K- (100 ml of well water), K+ (abate 100 ppm), P1 (8,000 ppm), P2 (12,000 ppm), P3 (16,000 ppm), P4 (20,000 ppm) and 4 replicates each. Data analysis was carried out using analysis of variance (ANAVA) and further tests in the form of Duncan's Real Distance Test (JNTD) and regression analysis probit. The results of the analysis of variance (ANOVA) test show that Fcount > Ftable = 190.50 > 2.77 at = 0.05. The conclusion of this research is the administration of onion peel extract white color affects the mortality of Aedes aegypti L. larvae so that the skin extract Garlic has the potential to be used as a natural insecticide, LC50 peel extract garlic which can kill 50% of Aedes aegypti L. larvae based on test probit regression analysis is at a concentration of 12,000 ppm, garlic peel extract cause behavioral changes in the larvae of Aedes aegypti L.
