Abstract

Abstract. The used of chemicals as mosquitos repellent may causing health problems. Extract of caffir lime (Citrus hystrix) as mosquitos repellent can be used as another option. The study aimed to analyze the protection capacity of C. hystrix against Aedes aegypti and Ae. albopictus. Experimental studies using completely randomized design was done. The obtained data were calculated using the protection capacity formula and analysed using t-test. The result indicated that protection capacity of Citrus hystrix extract for 6 hours on average gave 34.82% of protection against Ae. aegypti and 41.44% of Ae. albopictus. The caffir lime extract has been able to reject Ae. aegypti and Ae. albopictus. Although the thrust of the caffir lime is not as good as chemical products, but can be use as alternative mosquitoes repellent.

Penggunakan bahan kimia sebagai repellent dapat menimbulkan masalah kesehatan.  Ekstrak kulit jeruk purut (Citrus hystrix) sebagai penolak nyamuk dapat digunakan sebagai pilihan lain. Tujuan penelitian ini untuk menganalisa kemampuan daya proteksi ekstrak kulit jeruk purut  terhadap nyamuk Ae. aegypti dan Ae. albopictus. Penelitian eksperimen dengan metode rancangan acak lengkap telah selesai dilakukan.Data yang diperoleh telah dihitung menggunakan rumus daya proteksi dan dianalisis menggunakan uji beda. Hasilnya menunjukkan bahwa ekstrak kulit jeruk purut (Citrus hystrix) selama 6 jam  memberikan proteksi rata-rata 34,82% terhadap Ae. aegypti dan 41,44% terhadap Ae. albopictus. Ekstrak kulit jeruk purut mampu menolak nyamuk Ae. aegypti maupun Ae. albopictus. Meskipun kemampuan daya tolak kulit jeruk ini tidak sebagus bahan kimia, namun bisa dijadikan bahan alternatif penolak nyamuk.
