Kajian Angka Bebas Jentik (ABJ) pada Dataran Tinggi di Kelurahan Kemiling Bandar Lampung

Dengue Fever is caused by the dengue virus transmitted by humans through the bite of Aedes aegypti and Aedes albopictus mosquitoes previously infected with dengue virus from other dengue fever patients. The problem is that there is no vaccine or anti-viral drug for dengue hemorrhagic fever, an extraordinary event of dengue hemorrhagic fever if in the community: someone dies or the mortality rate is fifty percent of the previous one and in one month the number of dengue cases doubles from the previous year. Epidemiological control of the presence of mosquitoes through the 3M movement and the larva-free rate (ABJ) ≥ 95% of the national target. Alternative Fogging is carried out if three or more patients with unexplained fever are found and more than or equal to five percent of larvae are found. Therefore, it is necessary to observe the larval stage of DHF vectors to determine the distribution, mosquito density, the main habitat of larvae, and the alleged risk of transmission. The purpose of this study was to determine the House Index, Container Index, Bruteau Index, Density Figure and ABJ through a larval survey. The sampling technique used proportional random sampling. Research instruments: questionnaires, observation sheets, flashlight equipment to check for the presence of larvae. Results HI, BI and CI Habitat Index > 5%. The larva free rate in Sumberejo Prosperous Village was 87%, indicating a moderate density of potential dengue transmission, because it was below > 95%.

Survey Indeks Entomologi dan Identifikasi Larva Aedes Aegypti di Kelurahan Pampang Kecamatan Panakukkang Kota Makassar

One effort to control Aedes aedes. mosquitoes is by knowing the entomological index. The entomological index is an indicator of the density of Aedes aegypti larvae in a particular settlement which is an important consideration in determining effective vector control efforts. The success of larva monitoring is seen from the House Index (HI), Container Index (CI), Breteau Index (BI) and Larval Free Rate (ABJ), because these entomological indices are used to monitor the population density of Aedes spp in the spread of the dengue virus. The problem in this service is how to reduce the high number of dengue fever cases. This community service is to determine the larval density of the House Index, Container Index, and Breteau Index. The service methods used are surveys and observations. The results of the larval survey in Pampang subdistrict showed that the HI, CI and BI values ​​in Pampang subdistrict were respectively 26% (DF=4), 14.36% (DF=4) and 27.45 (DF=4) in the density category. moderate, while the larvae free rate (ABJ) is 79%, which still does not meet the Environmental Health Quality Standards standards in an area described as having an ABJ of less than 95%.

The results of the research showed that there was a relationship between knowledge, attitudes, eradicating mosquito nests, the color of the water reservoir, the location of the water reservoir, and the role of larva monitoring cadres (Jumantik) with the presence of Aedes aegypti mosquito larvae. It is hoped that the Payung Sekaki Community Health Center can provide KIE (Communication, Information, and Education) to the community regarding Dengue Hemorrhagic Fever (DHF), especially how to prevent the presence of Aedes aegypti mosquito larvae and the involvement of Jumantik Cadres is expected to be more active and effective.

ANALYZING THE EFFECT OF SIMILARITY FUNCTIONS ON PARTITIONING AROUND MEDOIDS ALGORITHM FOR MAPPING DHF DISEASE IN NORTH SUMATRA

Dengue hemorrhagic fever (DHF) is an acute febrile illness caused by a virus through the Aedes mosquito. North Sumatra is among the three provinces with the highest incidence and mortality rates in Indonesia. Mapping of DHF cases is very important in efforts to control and prevent the disease. The Partitioning Around Medoid (PAM) algorithm is commonly used to cluster DHF cases. The idea of PAM is a clustering algorithm with a similarity-based approach to grouping objects in one cluster. There are two main focuses in the research: mapping regencies/cities based on dengue case information and analyzing the performance of several similarity functions. The dataset includes variables of incidence rate (IR), case fatality rate (CFR), larva-free rate (ABJ), and population, obtained from the North Sumatra Provincial Health Office and the Central Statistics Agency (BPS). The analysis showed that three clusters were formed in North Sumatra Province. The first cluster includes regencies/cities such as Langkat, Deli Serdang, Karo, Simalungun, Dairi, Samosir, Humbahas, North Labuhan Batu, North Padang Lawas, South Labuhan Batu, Padang Sidempuan, Nias, South Nias, North Nias, and Sibolga. The second cluster consists of regencies/cities such as Medan, Binjai, Sedang Berdagai, Tebing Tinggi, Batubara, Asahan, Tanjung Balai, Labuhan Batu, Toba, North Tapanuli, Central Tapanuli, Gunungsitoli, and West Nias. The third cluster includes the regencies of South Tapanuli and Mandailing Natal. In addition, an evaluation was conducted using the Silhouette Index to measure the quality of the clustering. Based on the comparison using distance methods (Euclidean distance, Manhattan distance, Minkowski distance, and Chebyshev distance), the highest Silhouette Index value was obtained using Chebyshev distance, which amounted to 0.527554. This value indicates reasonable cluster quality. Thus, this study contributes to the mapping of DHF cases in North Sumatra Province and can be the basis for decision-making in overcoming the disease.

Evaluation of one-house one-larvae observer program in controlling dengue hemorrhagic fever in Central Sulawesi

Dengue hemorrhagic fever (DHF) is still a health problem in Poso District. This can be seen from the high number of DHF cases and potential outbreaks from 2017 to 2018. The local government took the initiative to prevent DHF outbreaks in Poso Regency. The Central Sulawesi Provincial Health Office and the Poso Regency Health Office have implemented onehouse one-larvae observer program in the Poso Kota Selatan District area by engaging the local government and community. The implementation of the program and its accomplishments requires evaluation. This study aims to evaluate the one-house one-larvae observer program using input, process, output, and outcome indicators. The research adopts a descriptive-qualitative approach, employing observation and interviews within an evaluation research design. Data analysis was performed using interpretation and triangulation methods. Policy documents are available, and human resources supporting the program are in compliance with the decree. However, the budget for the program is insufficient, while the available infrastructure is sufficient. The process indicators demonstrate satisfactory progress. Based on outputs, there was an increase in achievement against the program target of the number of buildings inspected by house larvae observers over four years. The outcome indicator in the form of the larvae-free rate increased by >90% during one year of program implementation. The implementation of local innovations initiated by the Regency Health Office and stakeholders’ engagement has been proven to increase community participation in programs that impact the achievement of program outputs and outcomes.

Spatial analysis and risk factors of dengue hemorrhagic fever in Yogyakarta city, 2017-2018

Background: Dengue hemorrhagic fever (DHF) is a public health problem with high morbidity and mortality rates. These diseases are caused by the bite of the Aedes aegypti mosquito. Yogyakarta City is one of the endemic areas of DHF in Indonesia. This study aims to analyze the spatial distribution of DHF incidents and determine the risk factors associated with DHF incidence in Yogyakarta in 2017-2018. Methods: This was a descriptive quantitative with an ecological study design and using secondary data. Data was analyzed using statistical analysis and spatial analysis.

DHF control is estimated due to the correlation of climatic factors and the incidence of DHF, control of vectors and disease agents, control of transmission media, and exposure to the community. Conclusions. The integration of DHF control can be used for early precautions in the era of the COVID-19 pandemic by controlling DHF early in the period from January to June in Surabaya. It is concluded that humidity can affect the dengue outbreak and it can be used as an early warning system and travel warning regarding the relative risk of DHF outbreak.

APPLICATION OF LETHAL OVITAP AS A MEDIA FOR CONTROLLING DHF LARGE VECTORS IN THE WORKING AREA OF SUKARAMI HEALTH CENTER, PALEMBANG CITY IN 2022

The Mosquito Nest Eradication Program (PSN) is currently not optimally implemented in controlling Dengue Fever vectors, so an alternative strategy is needed to overcome it, especially in the working area of ​​the Sukarami Health Center which has an incidence rate of Dengue Fever in 2022 of 21 cases with 2 deaths. One of the efforts carried out is a community-based larval survey that is sustainable with efforts to apply lethal ovitrap which can inhibit and break the developmental phase of the larvae. Activities carried out in the form of practice on how to make lethal ovitrap to cadres of larva monitors and the community directly. The larva monitors as an extension of the sanitarian/sanitation officer were given instructions on how to make lethal ovitrap, after which lethal ovitrap was made for the community whose family members were positive for Dengue Hemorrhagic Fever and the community around the house with a target of 105 houses with 10 jumantik and 2 lecturers as community administrators. and 10 students. From this activity, cadres of larva monitoring (jumantik) and the community were able to make lethal ovitrap and there was an increase in the larva-free rate (ABJ) after the application of lethal ovitrap which would reduce the breeding potential of Aedes aegypti mosquitoes in the larval phase. The results that have been achieved are 105 households surveyed by larvae and the practice of making lethal ovitrap by the community and cadres of larva monitors as an alternative effort in controlling larvae which can increase the larvae-free rate in the Sukarami Palembang Health Center area from 92.5% to 95%.

Correlation of Climate Factors, Population Density, and Larva Free Rate (ABJ) on the Incidence of Dengue Hemorrhagic Fever (DHF) in Kendari City Period 2012-2021

Background: Dengue Hemorrhagic Fever (DHF) is an infectious disease that is endemic in most tropical areas in the world and around 3.5 billion people live in areas where dengue is endemic. A large number of individuals residing in a certain area will facilitate the spread of dengue disease and accelerate the transmission of dengue virus from vectors. Climate is very important for the survival of the Aedes Aegypti mosquito because mosquito breeding sites will increase along with climate change. ABJ shows the density of larvae in an area. Purpose(s): This study aimed to determine the correlation of climate factors, population density, and larva free rate (ABJ) to the incidence of Dengue Hemorrhagic Fever (DHF) in Kendari City in 2012–2021. Methods: This research method was a cross sectional design and Spearman rank correlation analysis using SPSS application. The data used are secondary data in the form of data on rainfall, humidity, temperature, population density, and the incidence of DHF in a period of 10 years (2012-2021) and ABJ in a period 2016 - 2020. Results: The results of this study indicated that the rainfall variable (p value = 0,000, r = 0,416) and the humidity variable (p value = 0,000, r = 0,446) have a sufficient and unidirectional correlation coefficient to the incidence of DHF in Kendari City in 2012-2021, ABJ variable (p value = 0,014, r = -0,949) has a very strong and non-unidirectional correlation coefficient on the incidence of DHF in Kendari City in 2016-2020, and there is no correlation between the temperature variable (p value = 0,087) and the variable population density (p value = 0,651) with the incidence of DHF in Kendari City in 2012-2021. Conclusion: There was a correlation between rainfall and humidity variables on the incidence of DHF in Kendari City in 2012-2021, there was a correlation between the ABJ variable and the incidence of DHF in Kendari City in 2016-2020, and there wasn’t a correlation between temperature variable and population density variable on the incidence of DHF in Kendari City in 2012-2021.

The Relation between Rainfall and Larval Density of Dengue Hemorrhagic Fever with Spatial Modeling

Dengue Hemorrhagic Fever (DHF) is a disease transmitted by the aedes aegypti mosquito. This study aims to determine the relationship between rainfall and larval density which consist of House Index (HI), Container Index (CI), Breteau Index (BI), and Larval Free Rate (LFR) on the incidence of dengue hemorrhagic fever using GIS modeling. The research method is quantitative with a spatial approach and Univariate and Bivariate analysis. The study population was all cases of DHF in all working areas of Lahat District Health Center, Lahat Regency in 2016-2019. The results of the statistical correlation test showed that there was a correlation between rainfall and the incidence of DHF with a value (p=0.003), while larval density showed a correlation between HI and the DHF incidence (p-value=0.007), CI (p-value=0.007), BI (p-value=0.007). ABJ (p-value=0.012). Spatially, it was found that the incidence of dengue fever was high in the working regions of Public Health Center with high HI (≥5%), low CI (<10%), low BI (<50%), and low larvae-free rate (<95%). It can be concluded that there is a relation among rainfall, HI, CI, and BI on the incidence of DHF in Lahat Regency in 2016-2019 and spatially shows the high incidence of DHF in high HI (≥5%) and low LFR (<95%). It is recommended that the Lahat Regency Office used climate information from the BMKG in planning a program to eradicate DHF and eradicate mosquito nests during the rainy season in Lahat District.

Environmental Factors linked to the Presence of Aedes aegypti Larvae and the Prevalence of Dengue Hemorrhagic Fever

This study aims to examine the effect of climate and the presence of Aedes aegypti larvae on the prevalence of Dengue Hemorrhagic Fever (DHF) in Bukittinggi. In particular, the study was conducted in order to reduce the prevalence of DHF through vector control (Aedes aegypti) guided by the mosquito larvae free rate by proposing a model for environmental management in an Aedes aegypti larva-free area in Bukittinggi. Rainfall, air temperature, and humidity in 2015-2019 in Bukittinggi were measured to analyze their effect on the prevalence of dengue fever. Samples of data on the prevalence of dengue cases were carried out in total population against data on the prevalence of dengue cases, which amounted to 686 cases, and data on mosquito larvae free rates during 2015-2019. By using Pearson correlation analysis, the results show that the average air temperature in Bukittinggi over the last 5 years allows mosquitoes to survive because they have an average air temperature that functions as an optimum breeding vector. High rainfall can be expected to increase the breeding places of the Aedes aegypti so that the population will increase also has an impact on increasing cases in that month and several months later. Furthermore, the results confirm that there is no significant relationship and also no correlation between physical environmental factors, such as air temperature, humidity, and rainfall with the prevalence of dengue cases in Bukittinggi during the 2015-2019 period. Based on the pattern of distribution of DHF cases in Bukittinggi during the 2015-2019 period, controlling the prevalence of DHF cases needs to focus on activities in areas/villages that are endemic for DHF, without neglecting areas/villages where the prevalence of DHF cases is low, both at the temperature of the air and the mosquitoes will cause dengue fever experience optimal development, low, medium, and high rainfall, as well as in humidity where mosquitoes will experience ideal development.
