Angka kejadian DBD Provinsi Sumatera Barat tahun 2016 sebanyak 3.985 kasus dengan angka incidance rate 75,75 per 100.000 penduduk, angka kematian 0,45%. Salah satu pencegahan DBD adalah pengendalian kimia yaitu pemanfaatan ekstrak kulit jeruk manis (Citrus X Sinensis). Penelitian ini bertujuan untuk mengetahui konsentrasi yang paling efektif pada variasi waktu. Penelitian ini bersifat eksperimental dengan desain penelitian adalah post test only control group design. Penelitian ini dilakukan pada tanggal 13 Agustus s/d 28 Agustus 2018 di Laboratorium Sains Terapan. Populasi dan sampel penelitian adalah jentik nyamuk Aedes aegypti dan variasi konsentrasi. Analisis data menggunakan anova dan analisis probit. Hasil penelitian didapatkan pada konsentrasi 0% tidak ada jentik nyamuk yang mati. Masing-masing konsentrasi membunuh 25 jentik dengan waktu yang berbeda, seperti konsentrasi 5% dan 10% dalam waktu 300 menit. Pada konsentrasi 15% dalam waktu 240 menit. Pada konsentrasi 20% dalam waktu 180 menit. Nilai toksistas dari ekstrak kulit jeruk manis adalah 164,82g/ml (0,016%) eksktrak tersebut memiliki toksisitas yang sangat tinggi. Disimpulkan adanya perbedaan jumlah jentik yang mati dari variasi konsentrasi dan waktu. Semakin pekat konsentrasi maka jumlah jentik yang mati semakin cepat yaitu pada konsentrasi 20% dengan waktu 180 menit. Disarankan kepada peneliti selanjutnya untuk menambah variasi konsentrasi yang lebih besar agar bisa membunuh jentik nyamuk Aedes aegypti dalam waktu singkat.

The number of dengue fever cases in West Sumatra Province in 2016 was 3,985 cases with 75.75 per 100,000 populations, a mortality rate was around 0.45%. One of the prevention of DHF is chemical control for example the use of sweet orange skin extract (Citrus X Sinensis). This study aimed to determine the most effective time of this concentration used. This research was experimental with post test research design only control group. It was conducted on August 13 to August 28, 2018 in the Applied Science Laboratory. The population and study sample were Aedes aegypti mosquito larvae and variations of concentration. The data were analyzed by ANOVA and probit analysis. The results obtained that at 0% concentration, there was no larvae was dead. Then, each concentration killed 25 larvae at different times, such as concentrations of 5% and 10% within 300 minutes. After that, in 5% and 10%, it killed the larvae in 240 minutes. Moreover, a concentration of 20% spent 180 minutes to kill the mosquitoes. The toxicity value of sweet orange peel extract was 164.82 g / ml (0.016%). The extract had very high toxicity. In short, it was concluded that there were differences in the number of larvae that died from variations in concentration and time. The more concentrated extract use, the more larvae die (concentrations of 20% with 180 minutes). It was suggested to the next researcher to add a greater variation of concentration in order to kill Aedes aegypti mosquito larvae in a short time.
