The sample for this research is companies listed on the JII index for the 2017-2021 period with a final sample of 24 companies out of 26 companies. This research uses panel data regression data analysis methods. The results of this research are that the firm size variable has a significant but negative relationship with ISR disclosure, the profitability variable has a significant positive relationship and leverage has a significant negative relationship with firm value. Apart from that, the profitability and leverage variables do not have a significant relationship with the ISR score and the firm size variable and the ISR disclosure variable do not have a significant relationship with the firm value. for the intervening variable ISR disclosure is not able to mediate the independent variables profitability, firm size and leverage on the dependent variable firm value.
