ABSTRAK Demam berdarah dengue adalah salah satu masalah kesehatan di Indonesia. Cara pengendalian vektor salah satunya dengan larvasida. Senyawa yang terdapat dalam tanaman banyak dikembangkan sebagai larvasida ramah lingkungan. Penelitian ini bertujuan mengetahui efektifitas, LC50 dan LT50 ekstrak etanol bunga Krisan (Chrysanthemum morifolium). Penelitian ini dilakukan di laboratorium Parasitologi Fakultas Kedokteran Universitas Lampung. Jenis penelitian eksperimental menggunakan rancangan acak lengkap (RAL) dengan pola post test only control group design. Perlakuan dibagi menjadi 6 konsentrasi, terdiri dari kontrol negatif (0%), 0,25%, 0,5%, 0,75%, 1% dan kontrol positif (Abate 1%) diamati pada rentang waktu 5 sampai 4320 menit. Sampel 600 larva, tiap kelompok 25 larva 4 kali pengulangan. Uji yang digunakan adalah Kruskal-Wallis (p<0,05) ,Post Hoc Mann Whitney (p<0,05) dan uji Probit. Rerata prosentase kematian dari seluruh konsentrasi 92,4%. Nilai LC50 13,329% menit ke 20; 10,973% menit ke 40; 5,319% menit ke 60, 2,984% menit ke 120; 1,605% menit ke 240; 0,565% menit ke 480. Nilai LT50 249,972 menit pada konsentrasi 0,25%; 269,1 menit pada konsentrasi 0,5%; 102,775 menit, konsentrasi 0,75%; konsentrasi 1%;88,985 menit Bunga Krisan (Chrysanthemum morifolium) efektif sebagai larvasida alami. Nilai LC50 adalah 0,565 % dan LT50<4320. Kata kunci : Aedes aegypti, bunga krisan (Chrysantemum morifolium), demam berdarah dengue, larvasida ABSTRACT Dengue hemorrhagic fever is one of healthy problem in Indonesia. Larvacide is vector control. Utilization of herbal extract have been developed as larvacides that environmental friendly. This study aim to determine the effectiveness, LC50 and LT50 from krisan flower (Chrysanthemum morifolium) ethanol extract. Design of this study is randomized control trial method with post test only control group design, divide into 6 concentration consists of negative control (0%), 0.25%, 0.5%, 0.75%, 1% and positive control (Abate 1%), and observed at 5 to 4320 minutes. Used sample of 600 larvaes, divided into 25 larvaes each group in 200 ml solution with various concentrations and four with repetitions. This checking is used by Kruskal-Wallis method (p<0.05), Post Hoc Mann Whitney (p<0.05) and Probit test. The average number result of death larvaes is 92,4%. LC50 value was 13,329% at 20 minutes;10.973% at 40 minutes; 5.319% at 60 minutes; 2.984% at 120 minutes; 1.605% at 240 minutes; 0.565% at 480 minutes. LT50 value was 249.972 minutes at 0.25% concentration; 269.100 minutes at 0.5% concentration; 102.775 minutes at 0.75% concentration; 88.985 minutes at 1% concentration. Krisan flower (Chrysanthemum morifolium) is effective as natural larvacide with LC50 0.565% and LT50 <4320 minutes. Keywords : Aedes aegypti, dengue hemorrhagic fever, krisan flower (Chrysanthemum morifolium), larvacide
