PENGARUH STRUKTUR MODAL, PROFITABILITAS, DAN UKURAN PERUSAHAAN TERHADAP NILAI PERUSAHAAN INFRASTRUKTUR

This study aims to analyze the effect of capital structure, profitability, and firm size on firm value in infrastructure sector companies listed on the Indonesia Stock Exchange (IDX). Firm value in this study is measured using Price to Book Value (PBV), while capital structure is proxied by the Debt to Equity Ratio (DER), profitability is proxied by Return on Equity (ROE), and firm size is measured using firm size. This research uses a quantitative approach with a causal research design. The population of this study consists of all infrastructure sector companies listed on the Indonesia Stock Exchange during the period 2022–2024, totaling 70 companies. The sampling technique used was purposive sampling, resulting in 33 companies as research samples with a total of 99 observations. The data analysis method used in this study is multiple linear regression analysis with the help of the SPSS program. The results show that simultaneously capital structure, profitability, and firm size have a significant effect on firm value. Partially, capital structure has a negative and significant effect on firm value. Profitability has a positive and significant effect on firm value. Meanwhile, firm size has no significant effect on firm value. These findings indicate that the company's ability to generate profits is an important factor in increasing firm value, while a high level of debt tends to reduce investors' perceptions of firm value.
