Abstract

International trade is trade carried out by residents of a country with residents of other countries on the basis of a mutual agreement. One of the things that determines a country's economic growth is international trade which includes export-import activities. One advantage of international trade is that it allows a country to specialize in producing goods and services at low prices. This study aims to determine the effect of international trade on Indonesia's economic growth. The research method used to solve this problem is a quantitative method using multiple regression analysis and the classic assumption test from secondary data sourced from North Sumatra Economic Data (2001-2020). The results of this study are 1. Partially, imports have a significant positive effect on growth. Economics with the acquisition of a Prob. value of 0.0002 < apha 0.05 so that ha is fulfilled or ho is rejected and for the positive direction it is proven by the Coeffcient which is negative (1.216780). 2. Partially, exports have a negative but not significant effect on economic growth due to the acquisition of a Prob.0.2268> alpha 0.05 value so that ho is fulfilled or ha is rejected and for a negative direction it is proven by a negative Coefficient. (-0.448407) 3. Simultaneously Export and Import have a significant effect on Economic Growth with the acquisition of a Prob (F-Statistic) value of 0.00000 <0.05 meaning that the two variables significantly influence Economic Growth so that ha is fulfilled or ho is rejected 4. The Adjusted R-Square is 0.89, which means that much the two independent variables affect the dependent variable, namely GRDP, which means that there are still other models that affect the dependent variable.

Methods: This research uses secondary data obtained from the Central Bureau of Statistics (BPS) of North Sumatra Province for the 2001–2020 period. The analysis examines the relationship between exports and investment as independent variables and economic growth as the dependent variable, measured by Gross Regional Domestic Product (GRDP). Results: The results show that exports have a positive and significant effect on economic growth in North Sumatra Province. Investment also has a positive and significant effect on economic growth. Simultaneously, exports and investment significantly influence economic growth. The findings further indicate that exports and investment contribute 94% to economic growth in the province. Conclusion: Exports and investment play an important role in supporting economic growth in North Sumatra Province. Increasing export performance and investment levels can significantly enhance regional economic development. Originality/value: This study provides empirical evidence of the strong contribution of exports and investment to economic growth in North Sumatra Province using a 20-year observation period, highlighting their dominant role in regional economic development.

Abstract

Abstract: The problem addressed in this study is the low level of students learning motivation and economics learning outcomes, as indicated by the lack of active student participation in the learning process and the suboptimal achievement of learning outcames. One effort that can be made to address this issue is the implementation of the TGT learning model, which incorporates group collaboration, academic games, and competition to enhance student engagement in the learning process. This study aimed to determine the effect of the TGT learning model on the learning motivation and economics learning outcomes of eleventh-grade students at SMA Negeri 3 Medan, both partially and simultaneously. This study employed a quantitative approach with a quasi-experimental research design. The population consisted of all eleventh-grade students of SMA Negeri 3 Medan in the 2025/2026 academic year. The sample comprised Class XI-8 as the control group and Class XI-9 as the experimental group, selected using a purposive sampling technique. Data were collected through learning motivation observation sheets and learning achievement tests. Data analysis was conducted using descriptive statistics, normality tests, homogeneity tests, Independent Samples t-Tests, N-Gain tests, and Multivariate Analysis of Variance (MANOVA). The results showed tat the average learning motivation score of the experimental class increased from 29,53 on the pretest to 37,83 on the posttest, while the control class increased from 29,28 to 33,50. The result of the Independent Sample t-Test indicated that the TGT learning model had a significant effect on student learning motivation with a significance value of 0,000 < 0,05 and a t-value of -6,771. Furthermore, the TGT learning model also had a significant effect on students economics learning outcomes with a significance value of 0,000 < 0,05 and a t-value of -9,349. The N-Gain test results showed that the experimental group achieved an average N-Gain score of 63.31% (moderate category), while the control group achieved an average N-Gain score of 23.58% (low category). Furthermore, the MANOVA test results indicated a Wilks’ Lambda significance value of 0.000 < 0.05 and an F-value of 72.070, meaning that the TGT learning model simultaneously affected students’ learning motivation and economics learning outcomes. Keywords: Team Games Tournament (TGT) Learning Model, Learning Motivation, Economics Learning Outcomes.   Abstrak: Permasalahan dalam penelitian ini adalah rendahnya motivasi belajar dan hasil belajar ekonomi siswa yang ditunjukkan melalui kurangnya partisipasi aktif siswa dalam proses pembelajaran serta pencapaian hasil belajar yang belum optimal.
