Malaria is one of contagious disease which is still a crucial matter in Indonesia. Malaria disease control is being done by decreasing the number of malaria case gradually. South Kalimantan is one of high malaria prevalence province. Malaria cases occur nearly every month with significant raise of malaria occurence on May, October to July. This research intend to know the effect of rainfall, temperature and humidity on to occurence of Malaria case. This is a descriptive research, using secondary data of rainfall, temperature and humidity from Meteorology and Geophysics Board of Banjarbaru and Malaria case of Tanah Bumbu District data within 10 years term. This research shows that rainfall does effect the occurence of Malaria. Temperatur  and humidity does effect the occurence of Malaria. This result showed that rainfall does effect raise of mosquito density. Temperature does effect on mosquito density at 26,5 – 27 degree celcius. Humidity does effect on mosquito density at 85-87 percent. This research concludes that climate variable change does not directly effect raise of case.

ABSTRACT Dengue hemorrhagic fever is a global health problem and can be transmitted through vectors, namely Aedes aegypti. One of the controls can be through lethal ovitrap combined with attractant. This study aims to compare the percentage of trapped eggs, the number of eggs hatched, and larval mortality in the lethal ovitrap that were given two additional types of attractants. The insecticides used were temephos, while the attractants used were 20% straw soaking water, and water that Ae. aegypti have used to lay eggs. The type of research is an experiment with a completely randomized design. The sample used was female mosquito of Ae. aegypti that is full of blood from laboratory colonization. The results showed that straw soaking water was more influential attractant than the former Ae. aegypti colonization water in attracting Ae. aegypti mosquitoes to lay eggs. The highest larval mortality was found in a combination of lethal ovitrap with straw soaking water. Statistically there is an influence of the type of attractant on hatchability and the development of Ae. aegypti into adult mosquitoes. The combination of lethal ovitrap and attractant of straw soaking water can be an alternative control strategy for DHF program managers to reduce the density of Ae. aegypti mosquitoes and minimize transmission of dengue hemorrhagic fever in an area. Keywords: Aedes aegypti, attractant, lethal ovitrap, straw soaking water   ABSTRAK Demam berdarah dengue merupakan masalah kesehatan global dan dapat ditularkan melalui vektor yaitu Aedes aegypti. Salah satu pengendaliannya dapat melalui lethal ovitrap yang dipadukan dengan atraktan. Penelitian ini bertujuan untuk membandingkan persentase jumlah telur terperangkap, jumlah telur menetas, dan mortalitas larva pada lethal ovitrap yang diberi tambahan dua jenis atraktan. Insektisida yang digunakan adalah temefos, sedangkan atraktan yang digunakan adalah air rendaman jerami dengan konsentrasi 20%, dan air bekas kolonisasi/telur larva Ae. aegypti. Jenis penelitian ini adalah eksperimen dengan rancangan acak lengkap. Sampel yang digunakan adalah nyamuk Ae. aegypti betina yang kenyang darah hasil kolonisasi di laboratorium. Hasil penelitian menunjukkan bahwa air rendaman jerami merupakan atraktan yang lebih berpengaruh dibandingkan air bekas kolonisasi Ae. aegypti dalam menarik nyamuk Ae. aegypti untuk bertelur. Mortalitas larva tertinggi terdapat pada kombinasi lethal ovitrap dengan air rendaman jerami. Secara statistik ada pengaruh jenis atraktan terhadap daya tetas dan perkembangan Ae. aegypti menjadi nyamuk dewasa. Kombinasi lethal ovitrap dengan atraktan air rendaman jerami dapat menjadi strategi pengendalian alternatif bagi pengelola program DBD untuk mengurangi kepadatan nyamuk Ae. aegypti dan meminimalisasi transmisi penyakit demam berdarah dengue di suatu wilayah.

The use of ovitrap with attractants modification has been known as an alternative method in controlling DHF vectors. Attractant material will be better if it uses natural ingredients that are cheap and easy to obtain and easy to manufacture. Attractant material is recommended to use natural ingredients that are cheap and easy to obtain and are easy to make. Imperata plants can be easily obtained and easily processed as attractant material. This study aims to determine the effectiveness of attractants on a laboratory scale in the form of immersion water from the straw of the Imperata cylindrica plants in various concentration levels to Aedes aegypti eggs number. Research with an experimental design using a completely Randomized Design (CRD) was conducted at the Entomology Laboratory of the Tanah Bumbu Research and Development Center, in July 2019. Treatment concentrations consisted of 5%, 10%, 15%, and 20%, control using akuades. Samples for testing using Ae. aegypti gravid mosquitoes. Treatment with 5 repetitions, carried out for 7 days. Data analyzed by normality test, Anova test, and Least Significant Differences (LSD) test. The average number of eggs at concentrations of 5%, 10%, 15%, and 20% respectively was 45.00; 78.60; 129.40; and 174.00. Anova test showed Imperata cylindrica straw soaking attractant had a significant effect on oviposition of Ae. aegypti mosquitoes. LSD test results showed attractant 15% is the optimal concentration in increasing the number of eggs in the ovitrap.
