Mastery of concepts is still the main standard of learning success in Indonesia. This study aims to analyze students' conceptual mastery of colloidal material through the RADEC (Read, Answer, Discuss, Explain, and Create) learning model. The research method used is the Pre-Experiment method with the research design of One Group Pretest-Posttest Design. The number of subjects in this study were 18 students. Data were collected using 25 multiple choice items used for pretest and posttest. Data were analyzed through normality test, t test and N-gain using SPSS version 21 for windows. The results of the Paired Sample T-Test showed that there was a significant difference between the pretest score (39.7) and posttest score (74.4) (p<0.05) with the N-gain value obtained was 0.56. This means that there is an increase in the medium category in students' concept mastery through RADEC learning.

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.

The purpose of this study was to determine whether there is a difference in effectiveness between the participatory model and the discovery learning model on the mathematics learning outcomes of students at SMPN 21 Mataram on the subject of circles. This research is an experimental research type with the static group pretest-posttest desaign design. The sample in this study were students of class VIII SMPN 21 Mataram. The sampling technique in this research is purposive sampling with circle material. The research data collection process used interview, observation, and test instruments. From the research results, the participatory model of learning outcomes obtained an average pretest score of 58.68 and an average posttest score of 73.32. While the discovery learning model of learning outcomes obtained an average pretest score of 58.86 and an average posttest score of 73.91. The results of the hypothesis test of learning outcomes found that the sig. (2-tailed) 0.821. Because the sig value> 0.05, meaning that H0 is accepted and H1 is rejected, it can be concluded that there is no significant difference in effectiveness between the participatory model and the discovery learning model on the mathematics learning outcomes of grade VIII students of SMPN 21 Mataram

This study aims to determine differences in student learning outcomes using a model of learning make a match with a model partner switch the subject matter colloidal system class XI IPA MAN 1 Bengkulu City in the academic year 2017/2018. The research population of all classes XI IPA amounted to 4 classes with a total population of 151 students. The sampling of the research was done by normality test and homogeneity test before the study population. Obtained a sample of research that consists of 2 classes of class XI IPA 1 as an experimental class I that apply the model make a match and class XI IPA 2 as an experimental class II using a model parten switch. Student learning outcomes are seen from the postest score. Students' learning outcomes in the make a match class had an average of 82.714 while in the partner switch the average pair was 77.5. This shows that the model of make a match is more effectively used in the process of learning in class than the model of partner switch. From the t test-t test on both experiment classes is obtained tcount and ttable = 1.707> 1.666 (? = 0,05). The results show that H0 is rejected and Ha is accepted which means that there is a significant difference between the learning result of the students using make a match model and the learning model partner switch on the material of the colloidal system.

This study aims to analyze the performance of Islamic banking in Indonesia and Bahrain from the perspective of the maqashid shariah index. Performance is the success of an organization in implementing its strategy so that its achievement on the targets set. Maqashid shariah is a measurement of Islamic banking performance following the objectives and characteristics of Islamic banking. The research method used is descriptive and comparative methods, while the data analysis technique used is the independent t-test. The results of this study are that there is no significant difference between the application of Islamic maqashid in Indonesia and the implementation of Islamic maqashid in Bahrain. Thus, the application of Islamic values and the application of sharia maqashid has been integrated with Islamic bank business activities so that different government policies or regulations because each country has a specific constitution, then the impact is not significant or does not affect the implementation of sharia maqashid on operational and business activities in Islamic banks.JEL Classification: M41, M48, Z12 How to Cite:Nugraha, E., Nugroho, L., Lindra, C.

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.
