Incompatible insect technique (IIT) via releases of male Wolbachia-infected mosquitoes is a promising tool for dengue control. In a three-year trial in Singaporean high-rise housing estates, we demonstrated that Wolbachia-based IIT dramatically reduces both wildtype Aedes aegypti populations [reductions of 92.7% (95% CI: 84.7%-95.8%) and 98.3% (97.7%-99.8%)] and dengue incidence [reductions of 71% (43%-87%) to 88% (57%-99%)] in the targeted areas. The study highlights the need to ensure adequate vertical distribution of released males in high-rise buildings, address immigration of wildtype females from neighboring areas, and prevent and mitigate stable establishment of Wolbachia in field mosquito populations. Our results demonstrate the potential of Wolbachia-based IIT (supplemented with irradiation, in Singapore's context) for strengthening dengue control in tropical cities, where dengue burden is the greatest.

Abstract. Mosquitoes are insects that can transmit diseases to humans through their bites. Dengue haemorrhagic fever is one of the diseases that could be transmitted by Aedes aegypti mosquito. The use of insecticides to control the occurrence of dengue haemorrhagic fever builds resistance of the mosquito towards the chemical substance. Therefore, natural larvicide was used as an alternative to chemical insecticides. This research was conducted to study the effectiveness of larvicides from the ethyl acetate fraction of Bangun-bangun leaves (Plectranthus amboinicus) in killing the Aedes aegypti larvae and to identify the active larvicide compounds. This laboratory experiment research tested six extract concentrations (0.0; 1.0; 1.8; 3.2; 5.6; 10.0%) in three replications. Observations were administered for 48 hours to count the number of the dead Aedes aegypti instar III larvae obtained from the Entomology Laboratory of the Faculty of Veterinary, IPB. The results showed that the larvae mortality increased as the extract concentration increased. The percentage of Aedes aegypti killed reached 96% at an extract concentration of 10%. Meanwhile, the probit analysis showed that LC50 was found at a concentration of 5.56%. The identification of active compounds using GCMS revealed that the larvicidal compounds in ethyl acetate fraction were the ones from an organic acid group which were, stearic acid, and palmitic acid.  Keywords: Aedes aegypti, identification, larvacidal, mortality   Abstrak. Nyamuk merupakan serangga yang dapat menularkan penyakit melalui gigitannya. Salah satu penyakit yang ditularkan adalah demam berdarah dengue yang dibawa oleh nyamuk Aedes aegypti. Pengendalian demam berdarah dengue menggunakan insektisida berbahan kimia dapat menyebabkan resisten nyamuk terhadap insektisida meningkat, oleh karena itu larvasida alami diharapkan dapat menjadi alternatif pengganti insektisida kimia. Tujuan dari penelitian ini adalah mengetahui afektifitas larvasida dari fraksi etil asetat daun Bangun-bangun (Plectranthus amboinicus) terhadap mortalitas larva Aedes aegypti dan mengidentifikasi jenis senyawa aktif yang berperan sebagai larvasida. Penelitian ini merupakan eksperimen laboratorium dengan enam konsentrasi ekstrak (0,0; 1,0; 1,8; 3,2; 5,6; 10,0%) dan tiga kali ulangan. Pengamatan dilakukan selama 48 jam terhadap jumlah kematian larva Aedes aegypti instar III yang diperoleh dari Laboratorium Entomologi Fakultas Kedokteran Hewan, IPB. Hasil penelitian menunjukkan bahwa kematian larva meningkat seiring dengan meningkatnya konsentrasi ekstrak. Kematian Aedes aegypti mencapai 96% pada konsentrasi ekstrak 10% dan hasil analisa probit menunjukkan LC50 terdapat pada konsentrasi 5,56%.  Identifikasi senyawa aktif menggunakan GCMS menunjukkan bahwa senyawa yang bersifat larvasida dalam fraksi etil asetat ini adalah senyawa dari golongan asam organik yaitu, asam stearate, dan asam palmitat.  Kata Kunci: Aedes aegypti, identifikasi, larvasida, mortalitas

Tingkat kepadatan jentik merupakan indikasi diketahuinya kepadatan nyamuk Aedes sp yang akan menularkan virus dengue sebagai penyebab penyakit demam berdarah dengue (DBD) dan juga sebagai salah satu indikator keberhasilan kegiatan pengendalian vektor. Penelitian ini bertujuan mengetahui karakteristik tempat penampungan air (TPA) dan perbedaan kepadatan jentik House Index, Container Index, Breatau Index (HI, CI, BI) di Kelurahan Alak sebagai daerah endemis dan Kelurahan Belo sebagai daerah bebas DBD di Kota Kupang Tahun 2011. Penelitian observasional analitik ini menggunakan rancangan studi potong lintang. Variabel penelitian adalah jenis, kondisi, letak, bahan TPA dan kepadatan jentik Aedes sp. Data dikumpulkan dengan observasi langsung pada TPA dan rumah terpilih. Data disajikan dalam bentuk tabel kemudian dianalisis dengan uji-t. Penelitian ini menemukan TPA positif jentik paling banyak adalah TPA untuk kebutuhan sehari-hari, kondisi TPA tidak tertutup rapat, letak TPA di luar rumah, bahan TPA adalah bahan keramik, dan warna TPA adalah warna putih. Hasil penelitian menunjukkan nilai dari HI 0,887, CI 0,146 dan BI 0,080, yang artinya tidak ada perbedaan kepadatan jentik antara Kelurahan Alak (daerah endemis) dengan Kelurahan Belo (daerah bebas). Disimpulkan tidak ada perbedaan kepadatan jentik (HI, CI, dan BI) antara daerah endemis dan daerah bebas DBD. Kedua daerah sama-sama memiliki tingkat kepadatan jentik yang tinggi, sehingga disarankan pemberantasan sarang nyamuk tidak hanya diprioritaskan pada daerah endemis DBD tetapi juga daerah daerah bebas DBD. Water Container and the Aedes sp. Larvae Density in Endemic and Free Dengue Haemorrhagic Fever The larva density is an indication of the density of Aedes sp known to be capable of transmitting the dengue virus as the cause of dengue haemorrhagic fever (DHF) and also as one of the indicators of the success of vector control activities. This study aimed to determine the difference of the water container container characteristics and the larvae density (HI, CI, BI) in Alak village as an endemic area and in Belo Village as a free area of dengue in Kupang Municipality. This analytic observational study using cross sectional study design. Observed variables were the type, the condition, the location, the material of water container and also the larvae density. Data collected by direct observation in water container and house. Data presented in tables were analyzed by t-test. This study found positive larvae at most container is for everyday need, on not sealed condition, in outside the home, and in a ceramic material. The study also found the value of HI is 0.887, CI is 0.146 and BI is 0.080. It means that larvae density between Alak and Belo Village is not different. The conclusion is that there is no difference in the larvae density (HI, CI, and BI) between endemic area and free area of DHF. The two regions have the same high level of larvae density, so it is advisable that mosquito eradication is not only priority in endemic areas but also in dengue-free areas.

<p><em>Sampah menjadi permasalahan yang dapat menimbulkan dampak buruk bagi masyarakat, Permasalahan sampah dimulai sejak meningkatnya jumlah manusia dan hewan penghasil sampah (Suyono dan Budiman, 2010). Sampah menyebabkan berkembangnya beragam penyakit, terutama penyakit yang dibawa  oleh  vektor,  yakni  organisme penyebar  agen  pathogen  dari  inang  ke inang,  seperti  nyamuk  yang  banyak menularkan penyakit. Demam  Berdarah Dengue (DBD) atau Dengue  Haemorrhagic  Fever (DHF) merupakan  salah  satu  penyakit  yang disebabkan  oleh  nyamuk  spesies Aedes Aegypti dan aedes albopictus (DBD, 1999) sebagai  vector  primer,  serta Aedes polynesiensis, Aedes scutellaris serta Ae (Finlaya) niveus sebagai  vektor  sekunder. Dengan permasalahan tersebut, maka penelitian ini membahas tentang solusi yang efektif untuk mendeteksi nyamuk sebagai solusi pencegahan nyamuk di lingkungan sekolah. Penelitian ini membahas tentang bagaimana kesadaran masyarakat di lingkungan sekolah terhadap sampah yang dapat menyebabkan nyamuk berkeliaran dan meningkatkan korban penderita DBD (Demam Berdarah Dengue) pada anak-anak. Pendeteksi ini menggunakan Arduino Uno sebagai kontroller, Sensor Ultrasonik sebagai pendeteksi nyamuk, Serial Monitor sebagai alat pantau nyamuk. Dengan demikian, kesadaran dan kepedulian para siswa terkhususnya anak sekolah terhadap penanggulangan sampah akan meningkat dari sebelumnya. Inovasi ini juga dapat menjadi inovasi yang dapat menuju revolusi industri 4.0, karena lebih mengenalkan teknologi berbasis digital kepada anak sekolah.</em></p><p><em>Kata Kunci: Sampah, nyamuk, pendeteksi nyamuk, kesadaran anak sekolah, penanggulangan, revolusi industri 4.0</em></p><p align="center"><strong>Pedamuk Create A Quality School of Environment towards Industrial Revolution 4.0</strong></p><p><strong>ABSTRACT</strong></p><p><em>Waste becomes a problem that can cause adverse effects to the community, the problem of waste </em><em>is </em><em>started from the increasing number of people and waste-producing animals (Suyono and Budiman, 2010). Garbage will develop a variety of diseases, especially those carried by vectors, namely pathogenic agents that spread from host to host, such as mosquitoes which transmit diseases.

With these problems, this study discusses an effective solution to detect mosquitoes as a mosquito prevention solution in the school environment. This study discusses how public awareness in the school environment is about waste that can cause mosquitoes to roam and increase victims of dengue fever (Dengue Hemorrhagic Fever) in children. This detector uses Arduino Uno as a controller, Ultrasonic Sensor as a mosquito detector, Serial Monitor as a tool to monitor mosquitoes. Thus, the awareness and concern of the students especially the school children towards waste management will increase from before.

Provinsi bali  yang terdiri dari 9 kabupaten/kota adalah daerah endemis DBD, padahal Provinsi Bali adalah destinasi wisata baik lokal maupun mancanegara.Penelitian ini bertujuan untuk memberikan pemaparan berupa gambaran kejadian DBD di Provinsi Bali.Metode: Penelitian ini merupakan penelitian deskriptif dengan rancang bangun caseseries. Sumberdata pada penelitian ini menggunakan data sekunder yaitu Profil Kesehatan provinsi Bali tahun2015 hingga 2017, dan data iklim di Provinsi Bali tahun 2015-2017yang diperoleh dari Badan Pusat Statistik provinsi Bali.Hasil: Hasil penelitian menunjukkan insiden DBD per 100000 penduduk di Provinsi Bali tahun 2012 hingga tahun 2017  berturut turut 65,5: 174,5: 210,2; 259,1; 483; 105. Puncak insiden tertinggi Demam Berdarah Dengue (DBD) ada pada tahun 2016.Pada tahun 2017 ada 4 kabupaten/kota yang insidennya tinggi seperti kabupaten Badung , kota Denpasar , kabupaten Buleleng dan kabupaten Gianyar. Penyebab meningkatnya insiden DBD adalah banyaknya genangan air sebagai tempat perindukan nyamuk Aedes aegypti saat  musim hujan, sehingga populasi nyamuk Aedes aegypti meningkat. Insidens DBD terjadi pada bulan Januari hingga Mei, yang di pengaruhi oleh cuaca lokal, kondisi sosial ekonomi masyarakat, curah hujan, topografi maupun kepadatan,serta mobilitas penduduk.Simpulan: Insiden DBD dipengaruhi oleh pola musim hujan , di bulan Januari, Februari, Maret, April dan Mei  didukung kepadatan dan mobilitas dari penduduk. ABSTRACTTitle: An Overview of Dengue Haemorrhagic Fever Cases in Bali Island 2012-2017Background: Dengue Hemorrhagic Fever (DHF)remains a public health problem in Indonesia, including the island of Bali. Bali province consists of 9 regencies / cities is a dengue endemic area, whereas the island of Bali is a tourist destination both locally and internationally. This study aims to provide an overview of the incidence rates (IR) of DHF in the island of Bali.Methods: This research is a descriptive study with case series design. Data sources in this study use secondary data obtianed from Bali Health Profile 2015 – 2017, and the climate data of Bali Province in 2015-2017 was obtained from the Central Statistics Agency (BPS) of Bali Province.Results: The results showed the Incidence Rates (IR) of Dengue Haemorrhagic Fever (DHF) in the island of Bali in 2012- 2017 were 65.5; 174.5; 210.2; 259.1; 483 and 105.7 respectively. The highest incidence rates (IR) of DHF was notified in 2016. Up to 2017 there were 4 districts that had reported high incidence of DHF, such as Badung Regency, Denpasar City, Buleleng Regency, and Gianyar Regency. Factors contributing to the increasing incidence of DHF in Bali were the existence of water container as the potential breeding places for mosquitos vector of Aedes aegypti, particularly during rainy season. This condition initiated the increased population of Aedes aegypti. The incidence of dengue fever cases intensively occurred during January – May influenced by local weather climate, socio- economic condition, rainfall, topography, as well as population density and mobilityConclusion: The incidence of DHF is significantly associated with weather seasonal patterns whereasthe highest DHF incidence rates are found in each year in January, February, March, April and May. The other significant factors are including of rainfall, population density and mobility.
