Abstract

Population projection is not a population forecast but a scientific calculation based on assumptions of the components of the population growth rate, namely births, deaths and migration. These three components determine the size of the population and the age structure of the population in the future. In order to determine the assumptions of future developmental levels of births, deaths and displacement, data are needed that describe trends from the past to the present. Here the author will determine the projected population growth in Sumenep Regency on Madura Island using a logistic growth model. The population census of Sumenep Regency was obtained from the BPS (Central Statistics Agency) of Sumenep Regency from 2010 to 2020. Based on the results of the study, it was obtained that the Craying capacity was 1,141,132.5. The author can conclude that the model that is closest to the actual census value is called the best model by looking for the MAPE value of each model to find out the census value that is closest to the true value and here the logistical model 9 is the most accurate compared to other models, with a value of  and produces the equation  and based on model 9, the writer looks for the population census in 2040 with the value of  resulted in 1,127,590.627 people.

Abstract

TThe ability to solve problems is one of the abilities that students lack mastery of. This results in many difficulties faced when learning mathematics. This problem is not absolutely the student's fault. But the teacher as a facilitator also plays a very important role, one of which is the use of appropriate and efficient learning models to help improve these abilities, namely alternative choices with LAPS-Heuristics. This study aims to determine the effect of LAPS-Heuristic on the mathematical problem solving ability of SMPN 3 Kasokandel students. This study uses a mixed approach (mixed method) with data collection through test questions in the form of posttest, student response questionnaires, and documentation. The population used is two classes, namely the control and experimental classes, each of which is 24 students. The findings in this study are the LAPS-Heuristic learning model has an influence on the ability to solve mathematical problems of students by obtaining The level of problem-solving ability of the experimental class is greater than that of the control class, it can be seen from the average per indicator including indicators of knowing and understanding the problem of 90 and 71, indicators of planning problems of 80.25 and 60.5, indicators of implementing plans 87.75 and 67.25 and the indicator rechecked the results of 55.5 and 44. While the results of student responses are mostly positive with the acquisition of 90% and negative by 24%.

Abstract

The rate of return (return) and risk are inseparable in investing activities. One equilibrium model that describes the relationship between return and risk assumes that the expected return is influenced by more than one macroeconomic factor. Furthermore, the causal relationship between stock returns and macroeconomic factor returns was analyzed using VAR. The application of VAR in this study is to predict stock returns through the stages of checking data stationarity, determining the optimal lag length, testing Granger causality between variables, estimating VAR model parameters and Portmanteau diagnostic tests, and predicting stock returns. The results show that the VAR (1) model is the most appropriate model to describe the relationship between stock returns and macroeconomic factor returns with a significant model owned by BBCA, ICBP, INTP, KLBF, and SMGR stocks. Furthermore, the VAR (1) model is used to predict the five stock returns. The prediction results show that INTP's stock returns are negative while the returns of the other four stocks are positive. This shows that INTP shares experienced a capital loss, while the stock returns of BBCA, ICBP, KLBF, and SMGR experienced capital gains
