Ae.aegypti mosquitoes is very important in the transmission of this disease. One way of controlling the population of Ae. aegypti mosquitoes was done by using appropriate technology (TTG) larvitrap. This study was aimed to determine the preference and effectiveness of larvitrap TTG against Ae. aegypti. The research was conducted in Plumbon Pulo Village, Indramayu District, Indramayu Regency, West Java Province with experimental design at population level (community). The sample size was 546 larvitrap. Preferences test results showed that 72.0% of larvitrap TTG successfully trapped Ae aegypti larvae. The color and placement height do not affect the effectiveness of the larvitrap TTG. The straw water soaking media (polluted water) was the most preferred medium for Ae. Aegypti as a breeding habitat compared to other aquatic media. It can be concluded that the larvitrap TTG is suitab...

The success of regencies/cities in MDA after 5 years of implementation can be known through the TAS (transmission assessment survey). In 2017 an evaluation study was conducted to determine the failure and success of elimination of filariasis from epidemiological aspects (host, agent, environment) in 12 regencies endemic to zoonotic malayi filariasis who have passed TAS-1, TAS-2, and TAS-3. Evaluation study was carried out using finger blood sampling methods for residents, blood collection in reservoirs (long-tailed monkeys, cats and dogs) and vector mosquito capture. Finger blood test results on residents in 12 regencies: 3 regencies that have passed TAS-1 still found positive microfilaria populations, namely: Pasaman Barat (0.9%), Kuantan Singingi (0.2%), and Hulu Sungai Utara (0 , 2%). As well in the 3 regencies that have passed TAS-3, namely: Bangka Barat (0.6%), Belitung (1.2%), and Kotawaringin Barat (0.8%). Results of blood tests on the reservoir, were found to be positive for B. malayi in house cats in the regencies of Pasaman Barat, Pelalawan, and Kotawaringin Barat; long-tailed monkeys in Belitung and Kotawaringin Barat regencies; and dogs in Kotawaringin Barat regency. The mosquito vectors that were caught and tested positive DNA for microfilaria larvae based on PCR examination were Culex vishnui, Culex quinquefasciastus, Mansonia dives, Mansonia uniformis, Anopheles karwari, Anopheles karwari, Aedes aegypti, Aedes cancricomes, Aedes linneatopenis, and Armigeres kucingensis in the Pesisir Selatan, Pasaman Barat, Kuantan Singingi, Bangka Barat, Belitung, and Hulu Sungai Utara regencies. From the results of the study, even though an area has passed the TAS, transmission of the disease still occurs because of the presence of microfilaria in the reservoir and filaria larvae in mosquitoes. It is recommended that regencies that have passed the TAS continue to carry out active surveillance of vulnerable populations exposed in endemic villages.

Despite its importance, the spatial and temporal heterogeneity in dengue risk and factors associated with its variation in risk across the island has not been not well explored. This study was aimed to analyze for the first time the geographical and temporal patterns of the incidence of dengue and to quantify the role of environmental and social factors on the spatial heterogeneity of dengue incidence in Bali. Methods: We analyzed retrospective dengue notification data at the sub-district level (Kecamatan) from January 2012 to December 2017 which obtained from the Indonesian Ministry of Health. Seasonality in notified dengue incidence was assessed by seasonal trend decomposition analysis with Loess (STL) smoothing. Crude standardized morbidity rates (SMRs) of dengue were calculated. Moran's I and local indicators of spatial autocorrelation (LISA) analysis were employed to assess spatial clustering and high-risk areas over the period studied. Bayesian spatial and temporal conditional autoregressive (CAR) modeling was performed to quantify the effects of rainfall, temperature, elevation, and population density on the spatial distribution of risk of dengue in Bali. Results: Strong seasonality of dengue incidence was observed with most cases notified during January to May. Dengue incidence was spatially clustered during the period studied with high-risk kecamatans concentrated in the south of the island, but since 2014, the high-risk areas expanded toward the eastern part of the island. The best-fitted CAR model showed increased dengue risk in kecamatans with high total annual rainfall (relative risk (RR): 1.16 for each 1-mm increase in rainfall; 95% Credible interval (CrI): 1.03-1.31) and high population density (RR: 7.90 per 1000 people/sq.km increase; 95% CrI: 3.01-20.40). The RR of dengue was decreased in kecamatans with higher elevation (RR: 0.73 for each 1-m increase in elevation; 95% CrI: 0.55-0.98). No significant association was observed between dengue RR and year except in 2014, where the dengue RR was significantly lower (RR: 0.53; 95% CrI: 0.30-0.92) relative to 2012. Conclusions: Dengue incidence was strongly seasonal and spatially clustered in Bali. High-risk areas were spread from kecamatans in Badung and Denpasar toward Karangasem and Klungkung. The spatial heterogeneity of dengue risk across Bali was influenced by rainfall, elevation, and population density. Surveillance and targeted intervention strategies should be prioritized in the high-risk kecamatans identified in this study to better control dengue transmission in this most touristic island in Indonesia. Local health authorities should recommend travelers to use personal protective measures, especially during the peak epidemic period, before visiting Bali.

Until now it is known that the breeding sites of Aedes aegypti are found in urban areas, therefore the purpose of this study is to determine the potential for breeding of Aedes aegypti mosquito and entomology index in urban areas. The study was conducted in 2015 using a cross-sectional method. The results showed that the container with positively Aedes aegypti larvae was found in all three districts, Ternate at 29.6%, Tidore Kepulauan at 28.5% and East Halmahera at 29.0%. The entomology index of Container Index (CI) was (29.5%), House Index (HI) was 35.3% and Breteau Index (BI) was 69.2%, while larva free number was 64.7%. From the results of this study, it was concluded that Aedes aegypti larvae mostly found in bathtub inside the house. Tubs and plastic buckets were the type of container that were found with most positively larvae. The average ldengue vector arvae density based on CI, HI and BI...

Salah satu faktor yang menyebabkan peningkatan kasus DBD adalah iklim, antara lain curah hujan, hari hujan, suhu dan kelembaban. Tujuan dari penelitian ini adalah untuk melihat pola kecenderungan antara kondisi iklim dan kejadian DBD di Kota Yogyakarta. Bahan penelitian sumber data berupa menggunakan data sekunder, berupa jumlah kasus DBD yang berasal dari Dinas Kesehatan Kota Yogyakarta dan data iklim yang berasal dari Badan Meteorologi, Klimatologi dan Geofisika (BMKG). Data tersebut diambil dalam rentang waktu delapan tahun mulai dari 2004 sampai dengan 2011. Analisis data dilakukan secara deskriptif menggunakan software Minitab 16 statistical data dan program exelanalitik menentukan pola hubungan keterkaitan antara iklim, dengan mengambil kasus di hasil analisa memperlihatkan adanya keterkaitan peningkatan curah hujan, hari hujan, dan kelembaban serta penurunan suhu yang terjadi di bulan Januari-Maret dan Oktober-Desember hubungan antara dan hari hujan dengan dengan peningkatan jumlah kasus DBD yang terjadi di Kota Yogyakarta. Peningkatan kasus DBD dapat dipengaruhi oleh curah hujan yang berkisar di atas 200 mm dan hari hujan lebih dari 20 hari. Perkiraan perubahan suhu antara ±25-27 o C dan kelembaban sebesar 80-87% juga dapat mempengaruhi berpengaruh terhadap peningkatan jumlah kasus DBD sampai dengan lebih dari 200 kasus. Peningkatan jumlah kasus DBD tersebut disebabkan adanya peningkatan jumlah tempat perindukan nyamuk seperti genangan air sehingga terjadi peningkatan jumlah nyamuk. Dapat disimpulkan bahwa perubahan iklim dapat mempengaruhi kejadian penyakit DBD di masyarakat khususnya di Kota Yogjakarta sekitarnya.

The aim of study was determined the ability of the bacteria Bacillus sphaericus strain 2362 to eliminate of An. aconitus in the laboratory. The research was used experiment method with completely randomized design. Bacillus sphaericus Larvae was tested as 1000 was bred in the laboratory with different variation doses. The result was shown Bacillus sphaericus larvae strain An.aconitus 2362 that is effective to elimination at the water surface in application dose of 5 ml/m 2 and 10 ml/m 2 as indicated on Griselest product. The product mentioned that to elimination 50% and 85% of the population of a dose of 5 ml / m 2 takes over 12 and LT95 with range of time between 24-48 hours, while a dose of 10ml / m 2 is required LT 50 at the time between 6-12 hours, LD9 takes 12-24 hours. For applications under the water surface was shown larval mortality as much as 81-85% needed low dose of 2.5 ml / m 2 for 12 hours of exposure and LT95 with a time of 11-20 hours, whereas high doses of 6:25 ml / m 2 for 12 hours showed larval mortality as much as 86%. It can be concluded that Bacillus sphaericus an effective to eliminate the larvae An. aconitus in above and below the water surface with small doses.
