Abstract
Penelitian ini bertujuan untuk menganalisis pengaruh profitabilitas terhadap nilai perusahaan serta menguji peran inflasi domestik dalam memoderasi hubungan tersebut pada sektor pertambangan di Indonesia, yang dilatarbelakangi oleh fenomena ketidakselarasan antara lonjakan profitabilitas akibat commodity boom dengan respons pasar serta inkonsistensi temuan terdahulu. Menggunakan data panel dari 14 perusahaan pertambangan yang terdaftar di Bursa Efek Indonesia periode 2016-2024 dengan total 126 observasi dan metode analisis regresi moderasi melalui perangkat lunak PROCESS Macro v4.2, hasil penelitian membuktikan bahwa profitabilitas (Return on Assets) berpengaruh positif dan signifikan terhadap nilai perusahaan (Price to Book Value), yang mengindikasikan fungsinya sebagai sinyal efisiensi operasional yang direspons positif oleh pasar. Sebaliknya, inflasi domestik terbukti tidak memoderasi hubungan antara profitabilitas dan nilai perusahaan dan diklasifikasikan sebagai Homologizer Moderator. Temuan tambahan dari variabel kontrol menunjukkan bahwa struktur modal (Debt to Equity Ratio) berpengaruh negatif signifikan, sedangkan ukuran perusahaan (Firm Size) berpengaruh positif signifikan terhadap nilai perusahaan, di mana hasil ini tetap konsisten (robust) setelah dilakukan pengujian ulang menggunakan variabel alternatif Net Profit Margin dan Tobin’s Q.

| Additional Information: | This study aims to analyze the effect of profitability on firm value and examine the moderating role of domestic inflation in this relationship within the Indonesian mining sector, driven by the misalignment between profitability surges during the commodity boom and market responses, as well as inconsistencies in previous findings. Using panel data from 14 mining companies listed on the Indonesia Stock Exchange for the period 2016-2024 with a total of 126 observations and moderated regression analysis via PROCESS Macro v4.2 software, the results prove that profitability (Return on Assets) has a positive and significant effect on firm value (Price to Book Value), functioning as an effective signal of operational efficiency positively responded to by the market. Conversely, domestic inflation is proven not to moderate the relationship between profitability and firm value, acting as a Homologizer Moderator. Additional findings from control variables indicate that capital structure (Debt to Equity Ratio) has a significant negative effect, while firm size has a significant positive effect on firm value, with these results remaining consistent (robust) after re-testing using alternative variables of Net Profit Margin and Tobin's Q.
