“…Most of the previous literature in examining factors that affect financial performance only focuses on one of the variables used in this research such as leverage (Banafa et al, 2015;Isbanah, 2015;Rachman et al, 2015), capital structure (Setiana and Rahayu, 2012;Nirajini and Priya, 2013;Komara et al, 2016;Mwambuli, 2016;Taqwa, 2016), intellectual capital (Baroroh, 2013;Ciptaningsih, 2013;Trisnowati and Fadah, 2014;Nimtrakoon, 2015;Puspitosari, 2016;Setyawan et al, 2017), and environmental costs (Tunggal and Fachurrozie, 2014;Septiadi, 2016;Amani et al, 2020;Derila et al, 2020;Zainab and Burhany, 2020) or some, such as the firm size and environmental cost (Setiawan et al, 2018;Ladyve et al, 2020) and so on, so it is very limited to specifically use the variables of leverage, firm size, capital structure, intellectual capital, and environmental performance in one research concept, especially in mining sector companies whose application is minimal budgeting for environmental costs. Then, this research also used an observation period of six consecutive years, namely 2014-2019, so it is relatively different from previous researchers.…”
