Abstract

This research assesses how debt ratios influence the financial performance of Indonesian coal mining firms by utilizing regression analysis. A sample of 23 coal mining companies listed on the Indonesia Stock Exchange was studied, chosen through purposive sampling from a total of 33 companies between 2020 and 2023. Statistical analysis reveals that Debt to Equity Ratio significantly affects Financial Performance (ROE), demonstrated by a t-test significance value of 0.001 < α 0.05 and t-value of -3.390 > t-table 1.667. Similarly, Debt to Total Asset Ratio shows significant partial impact on ROE, with t-test results indicating significance of 0.005 < α 0.05 and t-value of 2.912 > t-table 1.667. The F-test confirms that both debt ratios simultaneously influence financial performance, showing significance of 0.003 < α 0.05 and f-value of 6.169 > f-table 3.130. The 0.152 R-squared value suggests that 15.2% of the variability in ROE is accounted for by the independent variables, leaving 84.8% of the variability to be influenced by unexamined factors in this research. The findings demonstrate that debt management strategies significantly impact financial performance in the coal mining sector.

Abstract

Diabetes mellitus is a chronic metabolic disease with a steadily increasing prevalence globally. Binahong leaves (Anrederacordifolia) and bay leaves (Syzygiumpolyanthum) contains flavonoids, such as kaempferol, which have the potential as antidiabetics, but its use is limited by the low solubility, stability, and bioavailability of the active compounds. This study aims to formulate and characterize a nanoparticle herbal medicine combining the two leaves using PlantCrystal technology, and develop it into an oral thin herbal preparation. The simplicia was processed through sorting, washing, drying, grinding, and sieving, then characterized and screened for phytochemicals. The nanoparticle herbal medicine was evaluated based on particle size, polydispersity index, zeta potential, and particle morphology. The membrane lysis release test showed an increase in the release of active substances compared to the simplicia. Furthermore, the formulation was developed into an oral thin herbal and evaluated for its physical properties, including organoleptic, water content, pH, film thickness, fold resistance, weight uniformity, and disintegration time.
