Dengue hemorrhagic fever (DHF) is still a serious health problem in the community. DHF is caused by the dengue virus (DENV) and is transmitted by the Aedes aegypti (Ae. aegypti) mosquito, which is the main vector for the virus. In controlling DHF vectors, larvicides are still used. These larvicides contain chemical compounds that have negative side effects affecting      the human body. Therefore, there is a need for natural-based larvacides (biolarvicides). The purpose of this study was to determine the potential of corn silk as a biolarvicide against dengue vector larvae (Aedes aegypti). This study was carried out at the STIKes Ngudia Husada Madura Bangkalan Laboratory and was done by taking corn silk waste samples disposed of as waste from corn farmers and corn traders in Bangkalan Regency. A Thousand samples of Aedes aegypti larvae that had reached instar III were used and divided into five test groups, namely 0 g/L (control), 6.25 g/L, 12.5 g/L, 25 g/L, and 50 g/L . Each group contained 200 larvae. The experiment was repeated 3 times. Data of the number of deaths of Aedes aegypti larvae were collected every 24 hours. The highest dose that could kill Aedes aegypti larvae was at 20 g/L.Keywords     : biolarvicides, corn silk, larvae, Aedes aegypti

AbstrakPengendalian vektor penyakit demam berdarah (DBD) di Indonesia menggunakan larvasida temephos telah berlangsung lebih dari 30 tahun, oleh karena itu, perlu dilakukan penelitian untuk mengetahui efektivitas temephos dan Bacillus thuringiensis var. israelensis yang merupakan larvasida jenis baru dari agen biologi terhadap larva nyamuk Aedes aegypti. Penelitian ini bertujuan untuk mengetahui perbandingan efektivitas temephos dengan B. thuringiensis var. israelensis terhadap mortalitas larva nyamuk Ae. aegypti dari tiga Kecamatan di Samarinda, yaitu Kecamatan Samarinda Utara Kelurahan Gunung Lingai, Samarinda Ulu Kelurahan Air Putih dan Sungai Kunjang Kelurahan Loa Bakung. Metode yang digunakan adalah metode bioassay. Hasil penelitian menunjukan bahwa temephos tidak efektif untuk membunuh larva nyamuk Ae. aegypti dari tiga kelurahan yang diamati, dengan LC50,24jam sebesar 1,88–2,24 ppm dan LC90,24jam sebesar 2,07–3,59 ppm. Sementara itu, B. thuringiensis var. israelensis masih efektif untuk membunuh larva nyamuk Ae. aegypti dari ketiga kelurahan yang diamati, dengan LC50,24jam sebesar 0,93–1,00 mL/50 L air dan LC90,24jam sebesar 1,05–1,11 mL/50 L air. Hal ini berarti penggunaan B. thuringiensis var. israelensis dengan dosis yang dianjurkan pemerintah masih efektif untuk mengendalikan populasi nyamuk Ae. aegypti.AbstractThe control of dengue hemorrhagic fever (DHF) vector in Indonesia using larvicide temephos has been ongoing for more than 30 years. Hence, it is necessary to assess the effectiveness of temephos compared to Bacillus thuringiensis var. israelensis which is a new type of biological larvacide agent against Aedes aegypti mosquito larvae. This study aimed to determine the effectiveness of temephos compared to B. thuringiensis var. israelensis against mortality of Ae. aegypti mosquito larvae sampled from three subdistricts in Samarinda namely Samarinda Utara Subdistrict Gunung Lingai, Samarinda Ulu Subdistrict Air Putih, and Sungai Kunjang Subdistrict Loa Bakung. The method used was bioassay. The results showed that temephos was not effective in killing Ae. aegypti mosquito larvae from the three subdistricts observed, with LC50.24 hours by 1.88–2.24 ppm, and LC90,24 hours by 2.07–3.59 ppm. Meanwhile, B. thuringiensis var. israelensis is still effective in killing Ae. aegypti mosquito larvae from the three subdistricts observed, with LC50.24 hours by 0.93–1.00 mL/50 L of water and LC90,24 hours by 1.05–1.11 mL/50 L of water. Those results mean that the application of B. thuringiensis var. israelensis with the recommended dosage of the government is still effective in controlling the population of Ae. aegypti.

Abstract. Cases of dengue hemorrhagic fever (DHF) are still a threat in Indonesia, especially entering the rainy season, the number of sufferers usually tends to increase, this occurs due to the proliferation of Aedes aegypti mosquito breeding breed. Prevention and eradication of dengue fever must be the responsibility of all communities. Efforts that can be done by the community are to be able to play an active role in monitoring mosquito larvae. This study aims to identify the knowledge and attitudes of the community in the prevention and eradication of dengue mosquito larvae. The head of the family in Jayaraga Garut, 103 kk, the amount of total populations, the study time was October 2018. Aspect Research Results Respondents' knowledge of participation in prevention and eradication of dengue vector still had 8 respondents whose knowledge was lacking. Attitude, there are still 9 responses whose attitude is not good. Participation in doing 3M most of the people of Jayaraga have prevented the breeding of the Aedes aegypti mosquito larvae even though there are still respondents who did nothing. The conclusion is that there are still some respondents whose knowledge, attitudes and actions are not good or not good.

Dengue hemorrhagic fever (DHF) is an infectious disease caused by dengue virus with the widest spread in the Asian region. In Indonesia, every year is always an outbreak in some provinces, the largest occurred in 1998 and 2004 with the number of patient mortality by 79 480 people with 800 people. To know the risk factor for dengue transmission in Cirebon District that had a high DHF cases, had been conducted the research with calculating the number and density of humans at the houses and also survey of density of Aedes aegypti pre-adult and adult stages.The research was resulting that the house index (HI) of Ae. aegypti is 58%, while homes found Ae. aegypti adults is 46%, 6 of which house is the house that is not found larvae / pupae of mosquitoes. The laboratory tests found that the frequency of biting Ae. aegypti mosquitoes average 4.5 times per day, at least 2 times and no more than 7 times per day. Number of people bitten by adult mosquitoes average of 3.1 people per day, is at least 2 people and maximum 5 people per day. Based on the statistically test, it is known that there is significant correlation between the number of inhabitants of the house and the presence of mosquito larvae / pupa of Ae. aegypti mosquito with biting frequency, whereas the most dominant variable was the presence of larvae / pupae of mosquitoes. Furthermore, it is advisable to do the cleaning intensification of Aedes breeding places inand outside the home including those hidden. It is also necessary to place residential settings so that the number of occupants per house so less.

Global Health Problem

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. Kata kunci: Aedes aegypti, atraktan, lethal ovitrap, rendaman jerami
