Dengue hemorrhagic fever (DHF) is a disease that is found in some tropical and subtropical regions. This disease is caused by dengue virus and is transmitted to humans through the bite of the Aedes aegypti mosquito. the solution taken in controlling DHF is to break the life cycle of the Aedes aegypti mosquito. Vector control is generally carried out using synthetic larvicides, namely abate / temefos, but the use of abate can cause residues, environmental pollution, poisoning and resistance of the eradicated vectors so that natural larvasides from plants are needed namely temulawak rhizome (Curcuma xanthorrhiza Roxb.) for vector control. The purpose of this study was to determine whether temulawak rhizome extract was effective or not in killing Aedes aegypti larvae. This research method includes larva collection, identification and maintenance of mosquitoes, determining sample size, making extracts and testing effectiveness. This study used a control and experiment group with 3 repetitions in the minutes to 15, 30, 45, 60 and 1440 (24 Hours). The control group was positive control using abate and negative control using aquades while the eksperiment group used extract of temulawak rhizome (Curcuma xanthorrhiza Roxb.) with concentrations of 0.6%, 0.8%, 1%, 1.2% and 1.5%. The results of this study indicate that the temulawak rhizome extract (Curcuma xanthorrhiza Roxb.) effective as larvicides because at the lowest concentration 0.6% can kill 100% Aedes aegypti larvae.

 Objectives: To analyze the effectiveness of the topical application of a standardized ethanol extract of roselle calyx in the treatment of oral mucous ulceration.Methods: Twelve Sprague Dawley rats were divided into two groups, with oral mucous ulcer being induced in all the rats. The ulcer diameter, reddish color, and the swollen membrane around the ulcer, as well as the inflammation score of the ulcer, were recorded for all animals. The negative control group was treated with aquades, while the positive control group was treated with 0.1% triamcinolone acetonide. The treatment group received the topical application of 7.5% and 15% standardized ethanol extract of roselle calyx twice a day for 3 or 7 days. On the 4th day, six rats were sacrificed, while the remaining six rats continued to receive treatment as before. On the 8th day, all the rats were sacrificed. Specimens were fixed, and histology slides were made. Further, microscopic slides were observed and scored.Result: Both the 7.5% and 15% standardized ethanol extracts of roselle calyx were found to reduce the ulcer diameter and inflammation score. No swelling or redness was observed.Conclusions: The application of 7.5% standardized ethanol extract of roselle calyx for 7 days is equally as effective as the application of 0.1% triamcinolone acetonides, except in terms of the decrease in the inflammation score.

Introduction: Dengue hemorrhagic fever is one of the most common infectious diseases in Indonesia. The vector of this disease is Aedes aegypti (Ae. aegypti). Dengue hemorrhagic fever can be controlled by a few measures, one of them is using insecticide. However, frequent use of chemical insecticide could lead to resistance and is harmful to non-target organisms. One of the solutions for this problem is the use of bioinsecticide derived from lemongrass (Cymbopogon citratus or C. citratus) leaves extract. Methods: The design of this study is true experimental post-test only control group. The population used are adult Ae. aegypti mosquitoes. For each experiment, 10 mosquitoes are required and given the extract of C. citratus in 2%, 10%, and 20% concentrations, and negative control respectively.The lethal effect of the extract is observed in 10, 30, 60 minutes and 6, 12, 18, 24 hours. Results: There is a significant difference in the lethal effect of Ae. aegypti mosquitoes with variations in duration of exposure to the C. citratus leaves extract (p = 0.007), but no significant difference with variations in extract concentration given (p = 0.281). Conclusion: C. citratus leaves extract has bioinsecticidal effect on Ae. aegypti mosquitoes. The optimal result of mosquito mortality is achieved by using the extract in 20% concentration with duration of 12 hours.
