Abstract

This study aims to determine the analysis of the effect of inflation and income on consumption in North Sumatra Province. The analysis method used in this study is a quantitative-descriptive method, with testing of instrument validity, instrument reliability, significance testing such as the T Test, Determination Test, and hypothesis testing. The independent variables used in this study are inflation and income, and the dependent variable is community consumption. Overall, the independent variables (inflation and national income) have a positive effect on community consumption. Based on the equation, it can be seen that the most influential independent variable is the income variable with a coefficient of 0.501, followed by the inflation variable with a coefficient of 0.381. Every increase in the score of the inflation variable (X1) will encourage an increase in community consumption (Y) by 0.381. Meanwhile, every increase in the score of the income variable (X2) will encourage community consumption (Y) by 0.501.

Abstract

Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi permintaan input dalam proses produksi, khususnya input modal dan tenaga kerja. Permintaan terhadap kedua input tersebut bersifat turunan (derived demand), yang artinya ditentukan oleh permintaan terhadap output yang dihasilkan. Dengan menggunakan pendekatan studi pustaka, penelitian ini menemukan bahwa tingkat upah, harga modal, kemajuan teknologi, dan struktur pasar merupakan faktor utama yang mempengaruhi permintaan input. Modal dan tenaga kerja tidak hanya berperan sebagai input terpisah, melainkan saling melengkapi dalam meningkatkan efisiensi dan produktivitas produksi. Hasil studi menunjukkan bahwa investasi modal dapat mendorong penyerapan tenaga kerja, sementara peningkatan produktivitas tenaga kerja berpengaruh pada pertumbuhan output dan pendapatan. Oleh karena itu, pemahaman mendalam mengenai dinamika permintaan input sangat penting untuk pengambilan keputusan ekonomi dan penyusunan kebijakan ketenagakerjaan.

Abstract

This study aims to analyze the characteristics of investment instruments in banking and non-banking financial institutions, simulate portfolio investment strategies, and identify financial risk mitigation efforts in the era of digitalization. The development of financial technology has increased public access to various investment instruments, but it is also accompanied by increasing financial risks that require proper management. This study employs a descriptive qualitative approach using literature review and conceptual simulation methods. The data used are secondary data obtained from official publications of financial institutions, regulatory reports, and relevant academic literature on investment and risk management. The simulation assumes an initial investment of IDR 50,000,000 allocated into three main instruments: deposits (40%), bonds (30%), and stocks (30%), and is tested under three economic conditions, namely stable conditions, rising interest rates, and declining stock markets. The results show that a diversified portfolio generates a return of 6.32% under normal conditions, increases to 6.95% during rising interest rates, and remains positive at 4.29% during stock market downturns. These findings indicate that portfolio diversification can help reduce risk exposure and maintain investment stability under various economic conditions. Therefore, diversification-based investment strategies, risk-based instrument selection, and active portfolio management can be considered relevant approaches for financial risk mitigation in the digitalization era
