Dengue Hemorrhagic Fever (DHF) is a severe and potentially lethal dengue virus infection. DHF control measures can be performed on adult mosquitoes or in larvae. Controlling the larval stage can be done by cutting the chain of transmission of dengue disease through containers that made Aedes aegypti mosquitoes laying and breeding. This study aims to determine the preferred container characteristics of larva Aedes aegypti in the work area of Puskesmas Bulili, South Palu District. This research will be carried out in the work area of Puskes Puskesmas Public Health Center by using spot survey method by observing all containers potentially become Aedes aegypti larvae breeding place in research location. The variables under study will be presented in descriptive form by describing the environmental characteristics of containers preferred by Aedes aegypti mosquito larvae ranging from type, base material and container location. The results showed that the type of container favored by Aedes aegypti mosquitoes is the type of bathtub with a base material made of plastic and the location of the container inside the community house.Keywords : DHF, Container, Aedes aegypti

Tujuan penelitian untuk memperoleh gambaran determinan penyakit Demam Berdarah Dengue di Desa Baka Kecamatan Tinangkung Kabupaten Banggai Kepulauan Tahun 2019. Jenis penelitian ini adalah Deskriptif. Populasi dalam penelitian ini ada seluruh rumah yang ada di Desa Baka berjumlah 657 rumah. Besar sampel berjumlah 250 sampel. Hasil penelitian menunjukan lingkungan fisik dikategorikan berisiko terhadap kejadian penyakit DBD disebabkan kelembaban udara di Desa Baka sangat berpotensi terhadap perkembangbiakan nyamuk Aedes aegypti; lingkungan biologi diperoleh gambaran sangat berisiko terhadap kejadian penyakit DBD karena pada umumnya di Desa Baka memiliki tempat perindukan dan adanya jentik nyamuk Aedes aegypti.  Berdasarkan perilaku masyarakat seperti: kebiasaan menggantung pakaian, kebiasaan tidur siang, kebiasaan membersihkan TPA dan kebiasaan membersihkan halamam rumah, dikategorikan berisiko karena sebagian besar masyarakat masih melakukan perilaku atau kebiasaan yang dapat memberikan peluang nyamuk Aedes aegypti berkembang biak sebagai penular agen penyakit DBD. Diharapkan pada pemerintah daerah untuk mengaktifkan kembali jumat bersih. bagi instansi terkait untuk lebih meningkatkan pelaksanaan penyuluhan tentang kebersihan lingkungan, pemberantasan sarang nyamuk dan pemberian abate pada tempat-tempat penampungan air. Kepada pemeritah kecamatan untuk dapat mengaktifkan kembali petugas Juru Pemantau Jentik (JUMANTIK) di Desa minimal seminggu sekali mengingat perkembangan nyamuk dari telur menjadi jentik membutuhkan waktu kurang lebih 7 hari. The purpose of this study was to obtain a picture of the determinants of Dengue Hemorrhagic Fever in Baka Village, Tinangkung District, Banggai Kepulauan Regency in 2019. This type of research is descriptive. The population in this study were all houses in the village of Baka totaling 657 houses. Sample size is 250 samples. The results of the study showed that the physical environment was at risk for the incidence of dengue fever due to air humidity in Baka Village, which had the potential to breed Aedes aegypti mosquitoes; biological environment obtained a very risky picture of the incidence of DHF because in general in the village of Baka has a breeding place and the larvae of Aedes aegypti. Based on community behavior such as: the habit of hanging clothes, the habit of taking a nap, the habit of cleaning landfill and the habit of cleaning the yard, are categorized as risky because most of the community still conducts behaviors or habits that can provide opportunities for Aedes aegypti mosquitoes to breed as infectious agents for dengue disease. It is hoped that the regional government will reactivate Friday's clean. for related institutions to further enhance the implementation of education on environmental cleanliness, eradication of mosquito breeding sites and the provision of abates in water reservoirs. To the district government to be able to reactivate the larvae monitoring officer (JUMANTIK) in the village at least once a week considering the development of mosquitoes from eggs to larvaes takes approximately 7 days.

Demam Berdarah Dengue (DBD) merupakan salah satu jenis penyakit menular yang disebabkan oleh virus dengue yang ditularkan melalui gigitan nyamuk Aedes Aegypti. Penyakit DBD dapat muncul sepanjang tahun dan dapat menyerang seluruh kelompok umur. Puskesmas Karya Wanita merupakan daerah yang endemis yaitu daerah yang mudah terjangkit penyakit dalam jumlah besar salah satunya penyakit DBD. Upaya dari pemerintah untuk mengatasi penularan penyakit DBD dengan melakukan program pengendalian DBD. Program pengendalian ini berupa pemberantasan sarang nyamuk, penyelidikan epidemiologi dan penggulangan fokus. Kegiatan ini mempunyai tujuan utama diantaranya untuk menurunkan angka kesakitan, menurunkan angka kematian, dan mencegah terjadinya KLB penyakit DBD. Tujuan penelitian ini untuk menganalisis pelaksanaan program pengendalian DBD di Puskesmas Karya Wanita Kota Pekanbaru tahun 2020. Penelitian ini merupakan penelitian kualitatif deskriptif dengan pendekatan studi kasus. Subjek penelitian ini terdiri dari 1 informan kunci yaitu Kepala Puskesmas, 2 informan utama yaitu Pemegang Program DBD, Petugas Promosi Kesehatan, dan 2 informan pendukung yaitu Kader dan Masyarakat. Teknik yang digunakan dalam penelitian ini adalah wawancara mendalam dengan menggunakan bantuan pedoman wawancara serta analisis data dilakukan secara deskriptif dan disajikan dalam bentuk narasi . Hasil penelitian ini menunjukkan bahwa pelaksanaan program pengendalian DBD belum optimal, hal ini disebabkan oleh kurangnya dana untuk melaksanakan program ini, dan juga masih kurangnya partisipasi masyarakat dalam melakukan program Pemberantasan Sarang Nyamuk (PSN). Diharapkan kepada pihak puskesmas agar dapat bekerjasama dengan pihak terkait seperti Dinas Kesehatan Kota/Provinsi dan lintas sektor dalam pendanaan untuk semua kegiatan pengendalian DBD dan lebih memotivasi masyarakat agar ikut serta dalam proses pengendalian DBD. Dengue Hemorrhagic Fever (DHF) is a type of infectious disease caused by the dengue virus which is transmitted through the bite of the Aedes Aegypti mosquito. DHF can appear throughout the year and can affect all age groups. Karya Wanita Public Health Center is an endemic area, namely an area that is easily infected by large numbers of diseases, one of which is DHF. Efforts from the government to overcome the transmission of dengue disease by implementing a dengue control program. This control program takes the form of eradicating mosquito nests, epidemiological investigations and focus repetition. This activity has the main objective of reducing morbidity, reducing mortality, and preventing outbreaks of dengue fever. The purpose of this study was to analyze the implementation of the DHF control program at  Karya Wanita Public health center Pekanbaru City in 2020. This research is a descriptive qualitative research with a case study approach. The subjects of this study consisted of 1 key informant, namely the Head of the Puskesmas, 2 main informants, namely the DBD Program Holder, a Health Promotion Officer, and 2 supporting informants namely Cadres and the Community. The technique used in this research is in-depth interviews using interview guides and data analysis is done descriptively and presented in narrative form. The results of this study indicate that the implementation of the DHF control program is not optimal, this is due to the lack of funds to implement this program, and also the lack of community participation in carrying out the Mosquito Nest Eradication (PSN) program. It is hoped that the public health center will be able to collaborate with related parties such as the City / Provincial Health Office in funding for all DHF control activities and to further motivate the community to participate in the DHF control process

Primary Fluid

Dengue viruses cause two severe diseases that alter vascular fluid barrier functions, dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). The endothelium is the primary fluid barrier of the vasculature and ultimately the effects of dengue virus infection that cause capillary leakage impact endothelial cell (EC) barrier functions. The ability of dengue virus to infect the endothelium provides a direct means for dengue to alter capillary permeability, permit virus replication, and induce responses that recruit immune cells to the endothelium. Recent studies focused on dengue virus infection of primary ECs have demonstrated that ECs are efficiently infected, rapidly produce viral progeny, and elicit immune enhancing cytokine responses that may contribute to pathogenesis. Furthermore, infected ECs have also been implicated in enhancing viremia and immunopathogenesis within murine dengue disease models. Thus dengue-infected ECs have the potential to directly contribute to immune enhancement, capillary permeability, viremia, and immune targeting of the endothelium. These effects implicate responses of the infected endothelium in dengue pathogenesis and rationalize therapeutic targeting of the endothelium and EC responses as a means of reducing the severity of dengue virus disease.

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.
