<p>Abstrak<br />Latar belakang: Nyamuk Aedes aegypti merupakan salah satu penyebab penyakit Demam Berdarah Dengue (DBD). Sebagai salah satu upaya pencegahannya, bahan tanaman sering dijadikan sebagai bahan <br />penolak nyamuk, di antaranya Zodia (Evodia suaveolens Scheff) dan Rosemary (Rosmarinus officinalis L.). Salah satu pengembangan yang banyak dilakukan adalah modifikasi sediaan yang mudah dipakai <br />agar lebih tahan lama, misalnya formulasi gel minyak atsiri. Tujuan dari penelitian ini yaitu mengetahui efek penambahan zat fiksatif (minyak nilam) terhadap daya proteksi repelan gel Rosemary dan Zodia.<br />Metode:Penelitian ini bersifat ekperimen yang menggunakan minyak atsiri dari bunga Rosemary dan daun Zodia dengan konsentrasi masing-masing 0,1%, 0,5%, 1%, 2%, 4%. Kontrol (+) menggunakan N,Ndiethyl-3-methylbenzamide (DEET) dan kontrol (-) menggunakan lengan tanpa perlakuan. Uji repelan menggunakan lengan sukarelawan yang sudah dilatih. Pengamatan dilakukan tiap jam selama enam jam. Daya proteksi baik jika bernilai 90% atau lebih. Hasil:Data menunjukkan bahwa penambahan zat fiksatif meningkatkan daya proteksi repelan mulai dari <br />konsentrasi 2% untuk Rosemary dan konsentrasi 4% untuk Zodia. Daya proteksi di atas 90% selama 6 jam. Kesimpulan:Penambahan zat fiksatif gel Rosseamary dan Zodia terbuti efektif untuk meningkatkan daya <br />proteksi repelen terhadap nyamuk Aedes aegypti.

One method of preventing dengue is to use bio insecticides from plants. A plant that is often used as a mosquito repellent is Zodia (Evodia suaveolens scheff) and Rosemary (Rosmarinus officinalis l.). Some studies have modified the dosage of bio insecticides to achieve more durable repellent, including developing a gel form. The aim of this study is to measure the protective effect of additional fixative material (patchouli oil) on Rosemary and Zodia repellent. Methods:This was an experimental study using gel made from essential oil of Rosemary flowers and <br />Zodia leaves with concentrations of 0.1%, 0.5 %, 1 %, 2 %, 4 %, respectively. Control (+) group used N, N-diethyl-3 (methylbenzamide (DEET) on the arms, while control (-) group were arms with no treatment.<br />The repellent was tested on the arms of trained volunteers, which were then observed every hour for six hours. The protective effectiveness was satisfactory if ≥90%. Results:Addition of fixative material increased the durability of repellent, starting from concentration of 2% for Rosemary and concentration of 4% for Zodia. The protective effectiveness was 90% for more than 6 hours. Conclusion:The modified gel of Zodia and Rosemary proved to be a potential repellent against Aedes aegyptimosquitos.
