Latar belakang : Penyakit demam berdarah dengue masih menjadi masalah di Indonesia khususnya di Kota Metro Propinsi Lampung, terjadi kenaikan jumlah kasus dari 11 kasus dilaporkan pada tahun 2003, menjadi 680 kasus dilaporkan pada tahun 2008. Vektor virus demam berdarah tersebut adalah adanya nyamuk Aedes aegypti. Strategi penanggulangan jentik nyamuk di sumur belum banyak mendapat perhatian. Tujuan Penelitian : Penelitian ini bertujuan untuk mengetahui karakteristik sumur yang mempengaruhi tempat perkembangbiakan nyamuk Ae.aegypti di wilayah Kota Metro Lampung. Metode Penelitian : Lokasi penelitian adalah kelurahan Ganjaragung kecamatan Metro Barat sebagai daerah endemis dan kelurahan Sumbersari Bantul kecamatan Metro Selatan sebagai daerah non endemis. Penelitian ini dilakukan secara observasional dengan desain cross sectional. Jumlah sampel 122 sumur terdiri dari 61 sumur berada di daerah endemis dan 61 sumur berada di daerah non endemis. Hasil : Analisis bivariat dengan 95% CI menunjukkan bahwa variable yang mempengaruhi keberadan jentik di sumur adalah kedalaman dasar sumur OR = 0,426 (p = 0,006), keberadan lumut OR = 1,336 (p=0,023), keberadan bakteri coli OR = 0,746 (p = 0,009), dan air sumur yang berasa OR = 1,212 (p= 0,038) . Hasil analisis multivariat menunjukkan bahwa tidak ada variable yang dominan berpengaruh terhadap keberadaan jentik di sumur. Kesimpulan : Kedalaman sumur, keberadaan lumut, keberadaan bakteri E.Coli dan rasa air sumur adalah variabel yang mempengaruhi keberadaan jentik di sumur.

Background: Disease dengue hemorrhagic fever is still a problem in Indonesia, particularly in Lampung Province Metro City, there was an increase the number of cases from 11 cases reported in 2003, to 680 cases reported in 2008. Vector the virus of dengue fever is the Aedes aegypti mosquito. Reduction strategies mosquito larvae in the wells has not been given due attention. Research Objectives: This study aims to determine the characteristics that affect the well mosquito breeding places in the area Ae.aegypti in Metro Lampung city. Research Methods: The research location is the village of West Metro Ganjaragung districts as endemic areas and urban villages in Bantul district Sumbersari South Metro as a non-endemic areas. This research was conducted in observational cross-sectional design. The number of sample consists of 122 wells in 61 wells in the endemic area and 61 wells located in non-endemic areas. Results: Bivariate analysis with 95% CI showed that the variables that affect the existence of larvae in the wells is the well depth OR = 0.426 (p = 0.006), the existence of moss OR = 1.336 (p = 0.023), the existence of the bacterium Escherichia coli OR = 0.746 (p = 0.009), and the taste of well water OR = 1.212 (p = 0.038). The results of multivariate analysis showed that there is no dominant variables which affect the presence of larvae in the wells. Conclusion: The depth of wells, the presence of moss, the presence of bacterium Escherichia coli and sense of well water is a variable that affects the presence of larvae in the wells.
