<![CDATA[ABSTRAK Efektivitas ekstrak daun Jeruk Keprok sebagai insektisida nabati merupakan alternatif ramah lingkungan dalam pengendalian jentik nyamuk Aedes sp sebagai vektor utama Demam Berdarah Dengue (DBD). Daun Jeruk Keprok mengandung flavonoid, alkaloid, dan tanin yang berpotensi menyebabkan kematian jentik Aedes sp. Penelitian ini merupakan eksperimen laboratorium dengan rancangan acak lengkap menggunakan 360 jentik instrar III. Perlakuan terdiri dari konsentrasi 0,05%, 0,075%,0,1%,0,25% dan 0,5% dengan tiga kali replikasi. Hasil analisis univariat menunjukkan jumlah kematan jentik meningkat seiring bertambahnya konsentrasi ekstrak. Pada konsentrasi 0,05% rata-rata kematian jentik sebanyak 8 ekor, sedangkan pada konsentrasi 0,5% rata-rata kematian mencapai 20 ekor selama 24 jam pengamatan. Hasil analisis One Way ANOVA menunjukkan terdapat perbedaan nilai signifikan antarperlakuan ( p < 0,05). Kesimpulan penelitian ini adalah ekstrak daun Jeruk Keprok berpotensi efekif sebagai lavarsida alami yang aman dan ramah lingkungan. ABSTRACT The effectiveness of Tangerine leaf extract as a botanical insecticide is an environmentally friendly alternative for controling Aedes sp larvae as the vector of Dengue Hermorrhagic Fever (DHF). Tangerine leaves contain flavonoids, alkoloids, and tannins which have the potential to cause larva mortality. This study aimed to describe the univariate analysis of the effectveness of Tangerine leaf extract based on concentration variations againts the mortality of Aedes sp larvae. This study was a laboratory experiment using a comletely randomized design with 360 third-instar larvae. The treatmens consisted of extract concentration of 0.05%, 0.075%, 0.1%, 0.25%, and 0.5% with three replications. The univariate analysis showed that larvae mortality increased along with higher extract concentrations. At the 0.05% concentration, the average mortality was 8 larvae within 24 hours of observation. In conclusion, Tangerine leaf extract has the potential to be an effective, safe, and environmentally friendly natural larvicide.]]>
