Upaya penanggulangan Demam Berdarah Dengue (DBD) dilakukan melalui pengendalian vektor Aedes aegypti secara fisik, kimia, dan biologi, serta penggunaan repelan seperti krim, spray, atau losion. Sejalan dengan konsep back to nature, Eucalyptus robusta Sm. berpotensi dimanfaatkan sebagai bahan alami penolak nyamuk. Tujuan penelitian ini mengetahui sifat fisik sediaan losion, efek iritasi, daya proteksi dan nilai analisis probit EC50 ekstrak n-heksana daun Eucalyptus robusta Sm. sebagai repelan terhadap nyamuk Aedes aegypti dalam sediaan losion. Penelitian ini menggunakan RAL (Rancangan Acak Lengkap) yang terdiri dari empat konsentrasi dan empat kali pengulangan. Konsentrasi ekstrak n-heksana Eucalyptus robusta Sm. yang digunakan yaitu 0%, 10%, 20%, 30%. Setiap konsentrasi diulang sebanyak empat kali. Losion memiliki sifat fisik yang baik, tidak menimbulkan iritasi dikulit. Hasil analisis daya proteksi menggunakan uji One Way ANOVA menunjukkan bahwa terdapat perbedaan yang signifikan terhadap jumlah nyamuk yang hinggap pada masing-masing konsentrasi perlakuan (p-value = 0,00). dan dilanjutkan uji Least Significant Difference (LSD) taraf 5%. Hasil penelitian menunjukkan losion konsentrasi 10%, 20%, dan 30% memiliki persentase daya proteksi berturut – turut sebesar 34,91%, 66,27%, dan 86,04%. Hasil uji probit EC50 untuk mengetahui efektivitas didapatkan bahwa konsentrasi yang efektiv sebagai repelan adalah pada konsentrasi 16,40%. Kesimpulan, losion ekstrak n-heksana daun eukaliptus menunjukkan daya proteksi sebagai repelan nyamuk Aedes aegypti terbaik pada konsentrasi 30%. Kata Kunci: Aedes aegypti, Demam Berdarah Dengue, Repelan, Daun Eukaliptus. Efforts to control Dengue Hemorrhagic Fever (DHF) are carried out through physical, chemical, and biological control of the Aedes aegypti vector, as well as the use of repellents such as creams, sprays, or lotions. In line with the concept of back to nature, Eucalyptus robusta Sm. has the potential to be used as a natural mosquito repellent. The purpose of this study was to determine the physical properties of lotion preparations, irritation effects, protective power and the EC50 probit analysis value of n-hexane extract of Eucalyptus robusta Sm. leaves as a repellent against Aedes aegypti mosquitoes in lotion preparations. This study used a Completely Randomized Design (CRD) consisting of four concentrations and four replications. The concentrations of n-hexane extract of Eucalyptus robusta Sm. used were 0%, 10%, 20%, and 30%. Each concentration was repeated four times. The lotion has good physical properties and does not cause skin irritation. The results of the analysis of protective power using the One Way ANOVA test showed that there was a significant difference in the number of mosquitoes that landed on each treatment concentration (p-value = 0.00). and continued with the Least Significant Difference (LSD) test at 5% level. The results showed that the lotion concentrations of 10%, 20%, and 30% had a percentage of protective power of 34.91%, 66.27%, and 86.04%, respectively. The results of the EC50 probit test to determine the effectiveness showed that the effective concentration as a repellent was at a concentration of 16.40%. In conclusion, the n-hexane eucalyptus leaf extract lotion showed the best protective power as a repellent for Aedes aegypti mosquitoes at a concentration of 30%. Key words: Aedes aegypti, Dengue Hemorrhagic Fever, Repellent, Eucalyptus
