Abstract

This research therefore aims to determine whether students’ understanding of mathematical concepts by applying active learning strategy types The Power Of Two is better than the students’ understanding of mathematical concepts with the application of learning conventional class VIII students’ of SMPN 2 Lubuk Sikaping school year 2013/2014. This type of research is experimental research. Population in this research is class VIII students’ of SMPN 2 Lubuk Sikaping consisting of six classes. The sampling technique is done randomly, which was selected as the sample classes are class VIII.5 as the experiments class and class VIII.6 as the control class. The instrument used in this final test with indicator of understanding the concept. Form of test used is a form of essay with a reliability test r11=0,901. Hypothesis testing use a t-test one direction. Based on the analysis of the data found ttable=1,678 dan tcount=1,861. Hypothesis is accepted because tcount>ttable is less than α=0,05. This concluded that the students’ understanding of mathematical concepts with aplikation of active learning strategies types the power of two is better that the students’ understanding of mathematical concepts with conventional learning in class VIII SMPN 2 Lubuk Sikaping Kabupaten Pasaman.

Abstract

This study aims to determine the effect of inflation, export-import, interest rates on sales in state-owned pharmaceutical holding companies with moderating variables of Gross Domestic Product (GDP). The type of research used is quantitative with primary and secondary data sources related to inflation, export-import, interest rates, GDP and sales. The data used is a combination of time series data for 2018-2022 and cross-section which is then referred to as panel data. The study was also conducted in more depth using a research instrument in the form of a questionnaire with respondents as many as six people who had positions as department heads in the parent company of Pharmaceutical SOEs. Data analysis techniques use multiple linear regression analysis and Moderating Regression Analysis. The results showed that simultaneously the variables of inflation, export-import and interest rates had a positive and significant effect on sales. Meanwhile, the moderation variable, namely GDP, partially affects sales, but cannot moderate the influence of inflation and export-import both in terms of strengthening and weakening the influence of the independent variable on the dependent variable. Other research results show GDP can be a pure moderator of the influence of interest rates on sales. This research has limitations, namely the variables used are macro, therefore for future research it is expected to be able to conduct research using micro variables in the economy. Keywords: Inflation, Export-Import, Interest Rate, GDP, Sales and Holding Company of SOEs.
