Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan Artificial Intelligence (AI) terhadap minat belajar di kalangan mahasiswa generasi Z, dengan studi kasus pada mahasiswa Pendidikan Ekonomi di Universitas Negeri Medan (UNIMED). Penelitian menggunakan metode kuantitatif dengan pendekatan regresi linear sederhana untuk menguji hubungan antara variabel independen (penggunaan AI) dan variabel dependen (minat belajar). Pengumpulan data dilakukan melalui penyebaran kuesioner daring menggunakan Google Form, dengan total sampel sebanyak 33 responden. Hasil penelitian menunjukkan bahwa terdapat hubungan yang linear antara penggunaan AI dan minat belajar mahasiswa. Temuan ini mengindikasikan bahwa penggunaan AI berpengaruh positif dan signifikan terhadap minat belajar, artinya semakin tinggi tingkat penggunaan AI yang dilakukan, maka minat belajar mahasiswa cenderung semakin meningkat. Berdasarkan hasil analisis, penggunaan AI secara konsisten berhubungan dengan peningkatan motivasi, pemahaman materi, serta ketertarikan mahasiswa dalam mengikuti perkuliahan. Dengan demikian, penelitian ini memberikan implikasi bahwa pemanfaatan teknologi AI dapat dijadikan salah satu strategi untuk meningkatkan minat belajar di lingkungan pendidikan tinggi.

Abstract

Poverty is a multidimensional issue that is still a serious challenge in development in North Sumatra Province. This study aims to analyze the effect of the Human Development Index (HDI) and Labor Participation on the poverty rate during the period 2010–2023. HDI is used as an indicator of quality of life through the dimensions of education, health, and standard of living, while Labor Participation reflects the involvement of the working-age population in economic activities. Secondary data used were obtained from the Central Statistics Agency (BPS). The analysis was carried out using multiple linear regression with the Ordinary Least Squares (OLS) approach and supported by classical assumption tests such as normality, multicollinearity, autocorrelation, and heteroscedasticity. The results of the study indicate that HDI has a negative and significant effect on the poverty rate, while labor participation does not have a significant effect partially. However, simultaneously, both variables jointly affect poverty in North Sumatra. This finding emphasizes the importance of inclusive human development policies and the creation of quality jobs to accelerate poverty alleviation.
