Abstract

ENGLISHDengue hemorrhagic fever (DHF) is still a health problem in Indonesia, transmited by Aedes aegypti. One of vector control method against Aedes aegypti larvae has conducted using Bacillus thuringiensis due to safe for the environment. The objectives of this study was to isolate and identify B. thuringiensis which toxic to Ae. aegypti larvae at various habitat and ecosystem in the District Magelangand magelang multicipality. Twenty-six soil samples collected from 10 locations were isolated and identified in the microbiology laboratory, Institute for Vector and Reservoir Control Research and Development, Central Salatiga. Twenty-six soil samples and 40 isolates were identified positive of B thuringiensis, 29 isolates had ˃50% toxicity and 11 isolates had ˂50% toxicity. Isolate with 90% toxicity were isolated from resting place ecosystem.Serological research needs to be conducted to identify the pathogenicity of isolates with ˃ 50% toxicity against Ae. aegypti larvae.INDONESIANDemam berdarah dengue (DBD) masih merupakan masalah kesehatan di Indonesia. Salah satu upaya pengendalian vektor penyakit tersebut adalah pengendalian terhadap jentik Aedes aegypti menggunakan Bacillus thuringiensis yang efektif dan aman bagi lingkungan. Tujuan penelitian adalah untuk mengisolasi dan mengidentifikasi B. thuringiensis yang toksik terhadap jentik nyamuk Ae. aegypti di berbagai lokasi di Kabupaten dan Kota Magelang. Dua puluh enam sampel tanah diambil dari 10 lokasi diisolasi dan diidentifikasi.di laboratorium mikrobiologi, B2P2VRP Salatiga diperoleh 40 isolat B thuringiensis, dimana 29 isolat yang didapat memiliki toksisitas ˃50% terhadap jentik nyamuk Ae. aegypti sedangkan sebelas isolat yang didapat memiliki toksisitas ˂50% terhadap jentik nyamuk Ae. aegypti. Isolat dengan toksisitas 90% diisolasi dari sampel tanah yang diambil dari habitat makam. Perlu dilakukan penelitian uji serologi dari isolat yang patogenisitasnya ˃50%.
