Abstract

Penelitian ini bertujuan untuk menganalisis penerapan fungsi linear dalam menentukan keseimbangan pasar melalui pendekatan matematis. Fungsi linear digunakan untuk merepresentasikan hubungan antara harga dan jumlah barang dalam fungsi permintaan dan penawaran. Metode yang digunakan dalam penelitian ini adalah pendekatan deskriptif kualitatif dengan analisis matematis sederhana berdasarkan data contoh. Hasil penelitian menunjukkan bahwa fungsi linear mampu menjelaskan hubungan antara variabel ekonomi secara sistematis serta menentukan harga dan jumlah keseimbangan pasar dengan mudah melalui persamaan matematis. Selain itu, faktor-faktor non-harga seperti pendapatan, selera, biaya produksi, teknologi, dan kebijakan pemerintah turut memengaruhi pergeseran kurva permintaan dan penawaran. Meskipun fungsi linear efektif sebagai alat analisis dasar, model ini memiliki keterbatasan dalam menggambarkan kondisi pasar yang kompleks di dunia nyata. Oleh karena itu, fungsi linear sebaiknya digunakan sebagai pendekatan awal dalam analisis ekonomi.

Abstract

This study aims to analyze the influence of e-wallet usage on the lifestyle of students in Class B of the Economics Department at Universitas Negeri Medan. The research is grounded in the rapid development of digital technology, which has driven the transformation of financial transactions toward cashless systems. The method used is qualitative descriptive, with data collected through questionnaires. The results show that e-wallets facilitate daily transactions, improve efficiency, and support a practical and digital lifestyle. However, this convenience also contributes to an increase in consumptive behavior, such as impulsive shopping and a tendency toward overspending. Although most students perceive e-wallets as a symbol of modernity, concerns remain regarding data security and technical issues. These findings suggest that e-wallet usage should be balanced with strong financial literacy to maximize its benefits while minimizing negative impacts on students' consumption patterns and financial management.
