Abstract

This study aimed to examine the effect of Profitability, Economic Value Added (EVA), and Market Value Added (MVA) on stock returns in the mining sector listed on the Indonesia Stock Exchange (IDX) for the period 2021–2024. The data used is secondary data from the financial reports of companies in the mining sector listed on the IDX. The research sample consists of 38 companies with a study period of 4 years, resulting in 152 firm-year observations. The sample was selected using purposive sampling, with data obtained through the official IDX website. Panel data regression analysis and hypothesis testing were conducted using EViews 12SV software.The results show that profitability has a significant positive effect on the stock returns of mining sector companies. EVA has a negative but insignificant effect on stock returns, while MVA has a significant positive effect on stock returns. Simultaneously, profitability, EVA, and MVA have a significant positive influence on stock returns in the mining sector. This empirical evidence not only contributes to the literature on value-based performance measures but also provides a strong foundation for evidence-based learning in higher education. By linking valuation metrics with real-world stock performance, the study supports the teaching of corporate finance, capital markets, and financial literacy in an Indonesian context.

Abstract

Fenofibrate acid is a fibrate drug with high permeability but low water solubility, resulting in limited bioavailability. Solid dispersion using hydrophilic carriers is one strategy to increase solubility. The objective of this study was to improve the solubility of fenofibric acid by converting it into a solid dispersion system using PEG 6000 as a carrier. Preparation of solid dispersion systems by the melting method. The fenofibric acid PEG 6000 weight ratios were F1 (1:1), F2 (1:3), and F5 (1:5). Physicochemical characterization of the solid dispersions included DSC, PXRD, FTIR, and SEM tests, as well as dissolution and bioavailability tests with the determination of pharmacokinetic parameters. Characterization results show that fenofibric acid with PEG 6000 as a carrier still exhibits a crystalline phase but with reduced intensity, resulting in increased solubility and dissolution rate. Dissolution test show that solid dispersion F3 (1:5) dissolves faster (78.7%) than pure fenofibric acid (53.2%). after 60 minutes. Pharmacokinetic parameter determination tests showed no significant difference between pure fenofibric acid and solid dispersion. Solid dispersion of fenofibric acid with PEG 6000 as a carrier can improve the physicochemical performance and dissolution rate of fenofibric acid but pharmacokinetic parameters did not differ significantly.
