No full textBased on research conducted at SMA Negeri 15 Bone, it shows that the mathematical reasoning abilities of students at this school are in the low category because the mathematics learning process is still dominated by teachers, which results in most students tending to accept whatever is said by the teacher, being silent and unwilling to express it. questions or opinions. This research is an experimental research with a Quasy Experimental Design research design in the form of Non-Equivalent Control Group Design which aims to find out the comparison between the GO CAR (Guided, Orientation, Challenge, Analysis, and Review) learning model and the GOLD (Guided, Organizing, Leafted) learning model. , Discovery) towards increasing students\u27 mathematical reasoning abilities. The population of this study were all students of class XI MIPA SMA Negeri 15 Bone. Samples were taken using a Non Random Sampling technique with Purposive Sampling type. Samples were taken from two classes, namely XI MIPA 6 as experimental class 1 and class and the GOLD (Guided, Organizing, Leafted, Discovery) learning model for improving students\u27 mathematical reasoning abilities. This can be seen from the data resulting from the hypothesis using the Mann-Whitney test, with a significance value of 0.419 > 0.05, so H0 is accepted and H1 is rejected. Thus, it can be concluded that in this research there is no comparison between the GO CAR (Guided, Orientation, Challenge, Analysis, and Review) learning model and the GOLD (Guided, Organizing, Leafted, Discovery) learning model in improving students\u27 mathematical reasoning abilities at SMA Negeri 15 Bone
Penerapan Metode ADL Pengaruh Harga BBM dan Jumlah Uang Beredar terhadap Inflasi di Kota Medan
No full textInflation is a general and continuous tendency to increase the price of goods. Factors causing inflation include increases in fuel prices and money supply. The general impact of inflation is a decrease in domestic investment, an increase in interest rates, encouraging investment through speculation, failure to develop, economic instability, a balance of payments deficit, and lowering the standard of living and welfare of the community.The purpose of this study is to determine the effect of fuel prices and the amount of money in circulation on inflation in the city of Medan. The model used is the Autoregressive Distributed Lag (ADL) Model. If the variables in the ADL model, both the dependent variable and the independent variable have a unit root, usually performed stasionary test. The ADL model as-sumes stationary data even if the dependent and independent variables are nei-ther stationary or cointegrated. The test results indicate that there is no cointe-gration between the variables, and the model produced indicates that the varia-bles affecting the price of fuel and the availability of money have a considerable impact on inflation, with a coefficient of determination of 71,4% and a MAPE value of 15,64%, making it suitable for making predictions
