Community-based DHF vector control has been implemented in Indonesia but has not yet obtained optimal results. Thus, in the community choosing synthetic insecticides to control disease vectors. However, irregular and excessive use of insecticides has a toxic effect and resistance to mosquitoes. Burning mosquito coils and incense containing synthetic dyes and fragrances have the potential to reduce environmental quality. Therefore, this research was conducted to analyze the toxicity of Legiayu incense as an insecticide and larvicide against Aedes aegypti mosquito mortality. The research design is experimental with a completely randomized design. Testing was conducted by providing exposure to smoke and ash of Legiayu incense five times on twenty-five Aedes aegypti mosquitoes. Statistical analysis used one-way ANOVA, LSD, and probit test. The test result as insecticide value (p=0.000) effective exposure for 20 minutes with a durability of 6 hours. The test result as larvicide value (p=0.000) effective exposure for 24 hours. Thus, exposure toismoke and ash of iLegiayuiincense has a very noticeable effect on the mortality of Aedes aegypti mosquitoes. Exposureito Legiayu incense smoke obtained an LT50 value of 0,9012 ≤ 5 (super toxic category) with a time of 15 minutes 39 seconds, coefficient determination of 99.24%, and correlation coefficient of 99.62% while exposure to the ash of Legiayu incense obtained LT50 value of 0,05896 ≤ 5 (super toxic category) with time 19 hours 15 minutes 34 seconds, coefficient determination and correlation coefficient of 100%. Histopathological test results showed that Legiayu incense smoke did not cause tissue degeneration, necrosis, hyperplasia, and metaplasia in the lung tissue of mice (mus musculus) within a period of 12 weeks. Thus, Legiayu incense is effective as insecticides and larvicides against Aedes aegypti mosquitoes. Legiayu incense has potential substitute for mosquito repellent coils, temephos, and synthetic incense circulating in the market.
Background: Refilled drinking water given by depots that currently have a permit for operation can be used to meet the community's drinking water demands. However, the quality of refilled drinking water has been tainted with pathogens that can cause health problems. Purpose: To assess the quality of replenished drinking water in Sesetan Village using Most Probable Number (MPN) Coliform and Escherichia coli as indicators. Method: A qualitative approach to descriptive observational research. The Ministry of Health standard 492/Menkes/PER/IV/2010 is used to assess drinking water quality. In this investigation, ten samples were used. Sampling was conducted in Sesetan Village, South Denpasar, Bali. Result: MPN Coliform was found in four samples: 96 MPN/100 mL (X1), 38 MPN/100 mL (X7), 15 MPN/100 mL (X8), and 5 MPN/100 mL (X10). Meanwhile, all of the samples tested negative for Escherichia coli. Conclusion: Based on drinking water quality criteria, 4 (40%) refilled drinking water depots (DAMIU) did not meet quality requirements (Ministry of Health Regulation number 492/Menkes/PER/2010).
Background: Each year, dengue hemorrhagic fever has grown. Clinical hematological examinations and blood preparations are used to confirm the diagnosis. Purpose: To detect, assess and characterize dengue hemorrhagic fever blood smear at Bali Royal Hospital. Method: Cross-sectional descriptive observational study-was conducted in April at Bali Royal Hospital on 37 patients with dengue hemorrhagic fever, clinical hematological tests and the manufacture of blood preparations identified using inclusion and exclusion criteria. Platelet counts, hemoglobin levels, hematocrit values, leukocyte counts, clinic degrees, gender and age, and blue plasma lymphocytes, are all used in hematological analyzed by univariate, ANOVA and BNT tests to analyze data. Result: Patients with dengue hemorrhagic fever are mostly toddlers and children (35.13%), women (54.0%), and dengue fever degree I (64.86%) with positive blue plasma lymphocytes (51.36%). Platelet counts, hemoglobin levels, hematocrit values, and leukocyte counts are significantly changed on days 3, 6, and 9, with probability values (p=0.000) less than p=0.01. The findings of the BNT test indicate that the number of platelets and haemoglobin on various days is significantly different (p<0.01), but the hematocrit value and leukocyte calculation are not significantly different (p>0.01). Conclusion: Clinical hematological tests and blood preparations reveal a blood component anomaly in Dengue Haemorragic Fever (DHF) patients at Bali Royal Hospital on days 3, 6, and 9.
