This research aims to examine the effect of the Debt to Equity Ratio (DER) on the stock value of PT. Ramayana Lestari Sentosa Tbk during the 2019-2023 period. Using quantitative analysis with dependent data obtained from the Indonesia Stock Exchange, the analysis shows that the company's DER was within a moderate range (35%-42%) throughout the study period. The results indicate a negative correlation between DER and stock prices; however, the effect is not significant when viewed partially. The decline in DER in 2023 reflects the company's efforts to strengthen its capital structure and reduce dependence on debt. These findings are expected to enhance investors' knowledge and support the company's operations in developing future financial and investment strategies.
