The purpose of this research was ti assess the roll’s impact also bass methods of brushing teeth and oral hygiene on fourth grade students of SD Negeri 58. Using the type one group pre-experimental design method, the researcher used a quantitative research method in this investigation. After implementing the roll method brushing intervention of 1.36, a difference of 0.8 was found compared to brushing teeth using the roll method with an average OHI-s of 2.16. Used the bass method, an average of 2.08 OHI-s was brushed. However, after the bass method brushing intervention of 1.16, a difference of 0.92 was found. It was determined that in the pretest and posttest brushing with the bass method, the the probability value was greater than the significance value, which were 0.000 <0.05 and 0.002 <0.05, respectively. Regarding enhancing oral and dental hygiene, brushing teeth with the bass approach works better for fourth grade students at SD Negeri 58 Banda Aceh City.

Dengue fever in Indonesia is still classified as a serious disease because it has increased yearly from 2011 to 2013. This study aims to determine the difference in the effectiveness of various types of water in the queue as a trap for eggs of Aedes aegypti mosquitoes in Bukittinggi. This type of research is experimental. The test used is the Anova test because the data is not normal using the Mann-Whitney test. The research sample used a sampling technique. This study uses primary data which can be seen from the number of trapped Aedes Aegypti mosquito eggs. The results showed that between the straw bales using well water and mineral water, the p-value was (0.421)> ? (0.05), meaning that there was no difference between the straw-soaked line with well water and water mineral. Meanwhile, after a statistical test was carried out between the straw bales using mineral water and rainwater, the p-value was (0.008)> ? (0.05), (Ho was rejected, Ha was accepted), meaning that there was a difference between the straw-soaked anthers and mineral water and rainwater. Based on the results of various types of attractants on the number of Aedes aegypti mosquito eggs trapped in the applied science laboratory of the University of Fort De Kock, Bukittinggi, the straw-soaked extract with rainwater is more effective because it produces more eggs than the extract soaked in straw with well water and extract soaked in straw with mineral water.

The average posttest value obtained was 81.94 which was in the 65-84 interval, which means it was in the high category. The research results were obtained by researchers using at distribution table with a significance level of a = 0.05 and d. b = N-1 =17-1=16 then we get t0.05 = 1.024. After obtaining t Count = 10.45 and t Table = 1.024, we get t Count > t Table or 10.45 > 1.024 so it can be concluded that the use of Interactive Power Point Media has an effect on the learning interest of class IV students at SD Inpres Paranga District.
