Abstract

Aedes aegypti L. is mosquito belong to the order diptera that widely distributed in the tropics. Female Aedes aegypti L. is the primary vector for the spread of dengue fever. Dengue fever has increased from year to year. Efforts to eradicate the disease done by government mainly using chemical insecticides which their residues can endanger non-target organisms. Eco-friendly Aedes aegypti L. larvae's control is needed to suppress the populations. One that can be achieve using natural larvacide from sugar apple (Annona squamosa L.). The aim of this research was to find out the LC 50 and toxicty effect of granule from sugar apple extract (Annona squamosa L.) on Aedes aegypti L. larvae’s mortality. The concentration used in this research were 1, 5, 25, 50, 75, 100, 125, 150 ppm, control 0 In the form of tween 80, positive control abate and negative control aquades. The result shows that LC 50 granule extract of apple sugar (Annona squamosa L.) was 8.25 ppm. Keywords: Aedes aegypti L., Annona squamosa L., granule, toxicity, LC 50

Abstract

Kombucha is a fermented drink from nata kombucha starter which is symbiosis between Acetobacter sp. And Saccharomyces sp. Which were grown in medium of A. bilimbi. A. bilimbi kombucha produces various types of acids, enzymes, alcohol and vitamins in addition A. bilimbi fruit contain flavonoids, alkaloids, triterpene saponins, terpenoids, and essential oil. This study aimed to analyze the influence of A. bilimbi kombucha on growth of E. coli. This kombucha has an antibacterial activity on E. coli growth. E. coli is a diarrhea causing bacterium. Concentration of kombucha used were 25%; 27.5%; 30%; 32.5%, and 35%. Antibacterial test using a pour plate method. Analysize tested using one way ANOVA and followed by post hoc test LSD with 95% levelof confidence. This research showed that Averrhoa blimbi kombucha perform antibacterial activity against E. coli and at concentration of 35% kombucha buluh perform inhibition which different significally (p>0.05). Keywords: A. bilimbi, A. bilimbi kombucha, E. coli.

Abstract

Propionibacterium acne and Shigella dysentriae is a species of bacteria that cause inflammation. Diseases that cause acne are often caused by a bacterial infection, one of which is the bacteria Propionibacterium acne. While inflammatory bowel disease caused by a bacterial infection Shigella dysenteriae. Both are bacteria that cause inflammation. One of the plants that have the potential as an alternative antibacterial is leaf dragon scales (Drymoglossum piloselloides Linn). Inhibition of leaf extracts dragon scales (Drymoglossum piloselloides Linn) against Propionibacterium acne bacteria significantly affect the significance value of 0,000. While the dragon scales leaf extract (Drymoglossum piloselloides Linn) against Shigella dysenteriae bacteria significantly affect the significance value of 0,000. Minimal Inhibitory Concentration (MIC) which is able to inhibit the bacteria Propionibacterium acne is 0,8% with a mean inhibition zone of 0,26 cm. While the Minimal Inhibitory Concentration (MIC) which is able to inhibit the bacteria Shigella dysenteriae is 0,6% with a mean of 0,15 Keywords: Propionibacterium acne, Shigella dysentriae, Drymoglossum piloselloides Linn., acne bacteria

Abstract

Earthworm (Pheretima javanica K.) is a common soil biofertilizer. This repulsive animal for some has been widely used for remedial medicine as well. Simplicia being used in this study was obtained from dried and blended earthworm along with its intact internal organs. The aim of the study was to determine the toxicity effect of earthworms powder to renal histopathology in rats (Rattus norvegicus). A total of 50 rats were divided into five groups consisting of a negative control group (2 ml 1% CMC Na), P1 earthworms group at dose of 0.4 grams, P2 earthworms groups at dose of 0.8 grams, P3 earthworms group at a dose of 1.6 grams, and P4 earthworms group at a dose of 3.2 grams. The rats were acclimated for about a week, then orally induced by earthworm powder. The treatments were conducted for 14 consecutive days to see any toxic symptoms developed. ANOVA results showed the administration of earthworm (Pheretima javanica K.) powder did not significantly affect renal physiology and histopathology. There was no damage observed microscopically. Keywords: Pheretima javanica K. powder, Rattus norvegicus B., renal histopathology.

Abstract

Aedes aegypti mosquito which is the main vector of the disease Dengue Hemorrhagic Fever (DHF) and Yellow Fever / Chikungunya. As a result of transovarial transmission of dengue virus within the body of the female mosquito Aedes aegypti into the eggs. The eggs hatch into larvae when already having dengue virus in his body without having to suck the blood of patients with DHF. Population density of Aedes aegypti larvae measured by the density and number of containers is very real impact on cases of dengue transmission. Two factors related to the presence and density of larvae itself include sociodemographic and environmental factors, both of which interact with each other. This study aims to determine the influence of sociodemographic and environmental factors on the population density of Aedes aegypti mosquito larvae in the Village Benculuk and to know the dominant factor causing population density of Aedes aegypti mosquito larvae. The design of the study design using qualitative methods. The results of the study showed the influence of the level of knowledge and behavior with the density of mosquito larvae of Aedes aegypti in the Village Benculuk, Banyuwangi. The influence of the distance between houses, the presence of water reservoirs and fish-eating larvae of the Aedes aegypti mosquito larvae density in the Village Benculuk, Banyuwangi. Environmental factors that affect population density dominates the mosquito Aedes aegypti larvae in the Village Benculuk, Banyuwangi. Keywords: sociodemographic, environmental, and Aedes aegypti.
