The purpose of this research was to analyze the effect of applying PSAK 72 on company value in companies indexed LQ-45 on the IDX. This type of research is descriptive using secondary data. The company population is companies listed on the IDX from 2017-2020, the research sample uses a "purposive sampling" technique using companies indexed at LQ-45. Hypothesis testing is counducted using the "E-Views" software. The partial test results indicate that the application of PSAK 72 has no significant effect on company value, while ROA has a positive effect on company value, and company size has a negative effect on company value. The results of the model indicate that the application of PSAK 72, ROA, and company size have a significant effect on company value and when viewed from the adjusted R-squared value, the application of PSAK 72, ROA and company size can predict company value by 94%, the remaining 6% is influenced by other factors that have not been studied.The managerial implication of this research is that it can be used as a consideration for management in making adjustments to changes to PSAK 72 in the financial statements so as to minimize the impact on company value
