Abstract

Purpose — This study aims to analyze the influence of profitability, leverage, and intellectual capital on financial distress in companies within the building construction sub-sector.Method — The research method involves quantitative and regression analysis. The sample consists of companies within the building construction sub-sector that consistently published financial reports during the period 2016-2021. The research population comprises 96 building construction companies listed on the Indonesia Stock Exchange, with 16 companies meeting the sample requirements. Data collection is performed using purposive sampling, and the analysis is conducted using EViews 10. Various tests, including classic assumption tests, feasibility analysis models, panel regression analysis, and coefficient of determination tests, are employed in the analysis.Result — The study results indicate a significant positive effect of profitability on the level of financial distress, suggesting that higher levels of profitability correspond to lower financial distress. Conversely, leverage demonstrates a significant negative effect on financial distress, implying that higher levels of leverage are associated with increased financial distress for the company. However, the study did not identify a significant relationship between intellectual capital and the level of financial distress, suggesting that the level of intellectual capital does not significantly influence the level of financial distress.Practical implications  — Management in the building construction sub-sector is encouraged to prioritize strategies and tactics aimed at enhancing company profitability. Focusing on efforts to improve operational efficiency, optimize asset utilization, and enhance the effectiveness of marketing strategies can contribute to an increase in the company's profitability.

Abstract

Ecoprint is an eco-friendly textile dyeing technique whose color quality is strongly influenced by mordanting and fixation processes. However, inconsistent mordant–fixative systems often result in unstable color intensity and poor standardization. This study aimed to evaluate the effect of different mordant and fixative combinations on the color characteristics of ecoprint fabrics dyed with indigo (Indigofera tinctoria), sappanwood (Caesalpinia sappan), and tannin extracts. Cotton fabrics were treated with either conventional mordant or color mordant, followed by fixation using vinegar, bone lime, lime, clear ferrous sulphate, or ferrous sulphate. Color properties were analyzed using UV-Vis spectroscopy (200-800 nm) and RGB evaluation. Iron-containing mordant systems significantly enhanced absorbance intensity in the visible region. It reduced the RGB lightness values, indicating deeper, more stable colors. Indigo showed maximum absorption at 647-672 nm, with the darkest blue obtained with the color mordant combined with ferrous sulphate fixation. Sappanwood showed maximum absorbance in the 482-491 nm range, under iron-assisted treatments. Tannin dyeing produced the most pronounced darkening effect due to tannin–iron complex formation. Overall, iron-assisted mordant–fixative systems under controlled pH conditions provided the most optimal and reproducible color performance, offering a scientific basis for standardizing the ecoprint process in sustainable textile production.
