Introduction: The COVID-19 pandemic has harmed various fields, and people's activities cannot run as usual. Prevention of the transmission of COVID-19 is very important to be applied in everyday life. Washing hands with soap or hand sanitizer is easy and inexpensive prevention to do, but there are still many people who are wrong in practicing it. This needs to be done more counseling and education to the community in order to increase public knowledge about handwashing and hand sanitizer. Method: This research is an analytic study with a research design using a one-group pretest-posttest design. Using 31 respondents from Taro villagers who attended the counseling. Data analysis using Paired Sample T-test and Kolmogorov-Smirnov Test for Normality Test. Result: The average value of knowledge before counseling is 53.8710 while the value after counseling is 82.9677. Paired Sample T-test and obtained a significance value of 0.000 so that a significant difference was found (<0.005) between the values before and after counseling. Conclusion: There is a significant difference in the level of knowledge before and after handwashing and hand sanitizer counseling.

The purpose of this research is to obtain the empirical evidence of the company which has already issued the obligation. Whether that such company issues the obligation manipulates its earnings (or conducting "the window dressing") in order to perform the financial report of the client (or the prospective obligation seller) seems more profitable and excellent. The data results front the research, taken from the company which issues the obligation and has been listed at Jakarta Stock Exchange (BEJ) or the company which is 'go public', by picking up the data during the obligation issuance, and also the period of time within two years before and after the issuance. Whether during that period of time, the financial report ofthet company is exactly appropriate or has been manipulated by the client.The data is analysed by using “normality test" (one sample kolmogorov smirnov) if the parameter'uses 'paired sample T-test ± > 0,005 and if non parameter uses whitney U ranks Wilcoxon rank sum W-test ± < 0,005. As a result, showing that not all companies which issue the obligation manipulate the earnings or make up their financial report. It has been proved, in this research there is no'management of earnings' before the obligation issuance as well as the changing profits after the issuance. Thus we conclude, there is no ‘management earning' during the obligation issuance. Therefore, the investor or the prospective investor is not necessarily anxious about theirfinancial report when is reported by the management side to Jakarta Stock Exchange (BEJ) due to the appropiateness of its financial report involving the earning management.

Background: Model analysis constitutes an essential aspect of orthodontic diagnostic practice. Pavan has developed an application to simplify the mathematical calculations employed in orthodontic model analysis. Purpose: This study was conducted to obtain the differences in results and time periods of model analysis using conventional means and iModelAnalysis. Methods: The research represented a comparative analytic study. The populations comprised dental casts dating from 2014 in the Orthodontics Laboratory of Padjadjaran University. The samples comprised 31 dental casts which were subjected to a total sampling method consisting of two treatments; a conventional method calculation and one using iModelAnalysis. A normality test was conducted and processed using a paired t-test with α=0.05. Results: The means of arch length discrepancies were 1.64±2.63 mm and 1.37±3.07 mm for the conventional methods and 1.65±2.43mm and 1.42±3.04mm for iModelAnalysis. The results of a Bolton analysis for conventional methods were 78.05±2.69% and 91.93±1.29%, while those for iModelAnalysis were 77.91±2.70% and 91.96±2.13%. A Howes analysis of conventional methods produced a result of 45.56±2.83%, while for an iModelAnalysis one of 45.56±2.85%. Pont analysis for conventional methods was 39.35±0.04 mm and 49.17±2.55 mm, while for iModelAnalysis it was 39.35±0.07 mm and 49.19±2.57mm. The mean of the duration of analysis using conventional methods was 1703.81±56.46 seconds, while for iModelAnalysis it was 990.06±34.87 seconds. A normality test confirmed that the data was normally distributed (p>0.05). The results of a paired sample t-test with p>0.05 showed that there was no significant difference between the results of each analysis, while there was significant difference in the time period of analysis. Conclusion: There was no difference in the analysis results. However, there was difference in the time period of analysis between conventional methods and that of iModelAnalysis.

Abstract: Chloride as the major anion in the extracellular fluid plays a role in maintaining fluid and electrolyte balance. One of the factors that influence the levels of serum chloride is sweating during physical exercise. This study aimed to determine  the differenceof serum chloride levels before and after moderate intensity exercise in the students of Faculty of Medicine year 2010 Sam Ratulangi University. This is a pre-exsperimental research with pretest and posttest design with 30 students as samples. The samples were chosen using purposive sampling method and the results were analyzed using paired-sample t-test. The results showed the average levels of serum chloride before and after moderate intensity exercise are 106,10 mEq/L and 107,37 mEq/L while paired-sample t-test significance value (p) is 0,000. From the results can be concluded that there is a significant differences in serum chloride levels before and after moderate intensity exercise in the students of Faculty of Medicine year 2010 Sam Ratulangi University.

Abstract: The Effect Of Lime (C10H16O) And Camphor (C10H16O) Against The Density Of Flies On Organic Waste. Fly is a disease-carrying vector so it is important to measure the density for control purposes. One of the controls that is done is on organic waste which is a breading source place of flies. Control is done by affixing the mixture of lime and camphor. This research aimed to determine the effect of mixture of lime and camphor against the density of flies in organic waste that is carried out in the garbage construction site while Southern Loktabat. This type of research is quasi-experimental that experimenting the provision of nine variations of dosage mixture of lime and camphor against the density of flies in organic waste with the organic waste sample was about 0,16m3. This research design used Pretest-posttest design. The analysis using statistical paired sample t-test, Kruskal Wallis test, and Least Significant Differences Test. The measurements showed a decrease in the density of the flies after administration of the lime and camphor mixture. Paired T-test results showed that in each treatment the p-value (2-tailed) <α (0.05) means that there is significant difference of flies density before and after treatment. Kruskal Wallis test result showed the p value (0,000) <α (0.05) which means there are significant differences between dosages. LSD test result showed that the most effective dosage is sixth dosage (35gr camphor+ 55gr lime/0,16m3 waste).
