Fransiscus Marcel Chris Danyarto, Yani Monalisa — Mon, 05 Jan 2026 00:00:00 +0000

This study aims to analyze the effect of the investment opportunity set (IOS) and capital structure (CS) on firm value (FV). The data were obtained from the annual financial reports of consumer goods companies listed on the Indonesia Stock Exchange (IDX) during the 2015-2019 period. This research employs a quantitative approach using secondary data. Out of a total of 61 consumer goods companies, 40 firms were selected as the sample and analyzed using multiple linear regression. The findings indicate that the variables market-to-book value of assets and debt-to-equity ratio have a partial effect on FV, whereas capital expenditure to book value of assets does not have a partial effect on FV. Simultaneous testing reveals that IOS and CS jointly exert a significant influence on FV, underscoring the importance of these factors in corporate financial performance.

This study examines the effect of institutional ownership on profitability and firm value, with profitability as a mediating variable, in manufacturing companies listed on the Indonesia Stock Exchange (IDX) from 2018 to 2022, variable control is firm size and interest rate. The research sample includes 54 purposive-sampled manufacturing enterprises. Secondary data from IDX and company yearly financial statements is used. STATA version 17 is used for structural equation modelling (SEM) with bootstrapping data analysis. The study found that institutional ownership increases profitability (ROE) and firm value (PBV) at 5% and 10% significance levels, respectively. Profitability also increases company value at a 1% significance level. Profitability also mediates the effect of institutional ownership on firm value at the 10% significance level, indicating that institutional ownership can increase firm value through increased profitability. This study helps explain how institutional ownership boosts business value through profitability. This research has implications for regulators (OJK & IDX) and policymakers regarding corporate governance. Managers need to strengthen governance and transparency to maximize profitability and enhance company value. To better understand how institutional ownership affects business value, future research should expand variables, incorporate data from various industries, and conduct cross-country studies.

The results showed that partially, visual aesthetics had no significant effect on impulsive buying, while storytelling had a significant effect. Simultaneously, visual aesthetics and storytelling together had a significant effect on impulsive buying.

Teacher performance is one of the essential elements for the continuous improvement of education quality. This performance can be influenced by various organizational factors, including the work environment and leadership of the principal. This research has a scientific objective, namely to analyze the effect of these two variables on teacher performance at SMA Negeri 1 Timika using a quantitative associative research design, conducted with 49 civil servant teachers from the school as respondents. A closed questionnaire survey was one of the main techniques used to obtain all the targeted research data. Teacher performance was proven to be a positive result of the principal's leadership, which confirms that the direction, guidance, and support of leaders have an important influence on improving the performance of their subordinates. Teacher performance was also proven to be a positive result of the work environment, which indicates that a conducive work environment, especially harmonious working relationships, also strengthens teacher performance. Simultaneously, these two variables explain more than half of the variation in teacher performance, thus showing that organizational factors contribute substantially to the effectiveness of educators' work. These findings conclude that optimal teacher performance is the positive result of competent leadership and a conducive work environment. The implications of this study emphasize the need to strengthen school management, improve working conditions, and provide more optimal managerial support to encourage the continuous improvement of teacher professionalism.
