Abstract

This study aims to identify factors that influence young voters' preferences in the 2024 presidential election in Medan City. There are 12 independent variables used in this study, namely socio-culture, age, education, track record, policy, political issues, political interest, campaign, social media, trust, candidate quality, and debate results. The dependent variable is voter preference, with a value of 0 for not voting and 1 for voting. This study used binary logistic regression method with purposive sampling technique to collect data from 271 respondents of young voters in Medan City. The results show that the independent variables jointly affect the dependent variable, as indicated by the G-test value of 85.909 which is greater than the value of χ_((0,05;12))^2(21.026). Through the Wald test, it is known that there are 6 independent variables that have a significant effect on the dependent variable, namely socio-culture (9.011), age (11.339), track record (4.638), political issues (4.403), campaign (4.165) and debate results (13.901), where these values are greater than the value of χ_((0,05;1))^2(3.841). While the remaining 6 variables, namely education (1.203), policy (0.072), political interest (1.435), social media (0.128), trust (1.557), and candidate quality (1.891) have no significant effect on the dependent variable, because the Wald test values of the six variables are smaller than the value of χ_((0,05;1))^2(3.841).

Abstract

The methods used in this research are the Least Square method and the Moving Average method. The use of this method is intended to compare which method is the most accurate and has the smallest forecasting error using the Mean Absolute Percentage Error (MAPE) method. The data used in this research is data on the number of visitors to the Panorama Geosite Hutaginjang tourist attraction from December 2021 to May 2024. The results of research and data analysis found that the MAPE values ​​for the Least Square method, Moving Average period 3 (MA(3)) and Moving Average period 5 (MA(5)) are 16.627% , 21.691% and 19.703%. From the MAPE values ​​obtained, it can be determined that the most accurate method is the Least Square method.
