[ABSTRAK
Penyakit Demam Berdarah Dengue (DBD) yang angka kejadian kasusnya masihtinggi di Indonesia, dapat dicegah melalui pemberantasan vektor DBD salahsatunya dengan menggunakan agen biologis yaitu Bacillus thuringiensis israelensis (Bti). Tujuan penelitian ini untuk mengetahui efektivitas penggunaanBti terhadap pengendalian larva Aedes aegypti di Tempat Penampungan Air (TPA) yang terkena cahaya. Desain penelitian ini adalah kuasi eksperimentaltanpa alokasi random dengan menggunakan daerah kontrol (Kelurahan Cempaka Putih Barat) tanpa pemberian Bti dan daerah intervensi (Kelurahan CempakaPutih Timur) yang dilakukan aplikasi Bti. Hasil penelitian menunjukkan bahwa pemberian Bti dapat menurunkan jumlah larva positif di daerah intervensi. Tetapi dengan analisis secara statistik menggunakan uji Chi square didapatkan bahwa tidak terdapat perbedaan bermakna antara proporsi kepositifan larva di daerahkontrol dan intervensi (p=0,88). Hal ini berarti penurunan jumlah larva positif yang terjadi pada daerah intervensi kemungkinan bukan disebabkan karenaaplikasi Bti, tetapi disebabkan oleh faktor lain. Jadi dapat disimpulkan bahwa Bti belum dapat dikatakan efektif dalam menurunkan jumlah larva positif Aedesaegypti di TPA yang terkena cahaya di Kelurahan Cempaka Putih Timur, Jakarta Pusat.ABSTRAK
Dengue Haemorrhagic Fever (DHF) disease which the number of case is still high in Indonesia, can be prevented through the eradication of dengue vectors, one ofthem is using biological agents namely Bacillus thuringiensis israelensis (Bti). The aim of this study is to know the effectiveness of using Bti for controllingAedes aegypti larvae in container exposed to light. The design of this study is quasi experimental with no random allocation using the control region (KelurahanCempaka Putih Barat) without giving Bti and area of intervention (Kelurahan Cempaka Putih Timur) with Bti application. The results show that Bti can reducethe number of positive larvae in the area of intervention. But with the statisticalanalysing using Chi square test show that there is no significant difference between the proportion of positivity of larvae in the control and intervention area(p=0,88). This means decreasing the number of positive larvae that occured in the area of intervention is not likely caused by the application of Bti, but caused byother factors. So it can be concluded that Bti still can not be said to be effective in reducing the number of positive larvae of Aedes aegypti in the container exposedto light at Kelurahan Cempaka Putih Timur, Central Jakarta. , Dengue Haemorrhagic Fever (DHF) disease which the number of case is still highin Indonesia, can be prevented through the eradication of dengue vectors, one ofthem is using biological agents namely Bacillus thuringiensis israelensis (Bti).The aim of this study is to know the effectiveness of using Bti for controllingAedes aegypti larvae in container exposed to light.
