Misconceptions are understandings that do not conform to scientifically accepted concepts, but are believed to be true by students. Misconceptions in elementary school students tend to be resistant and difficult to change if not identified early. This study aims to analyze the misconceptions of sixth grade elementary school students on the material of the human movement system. This material is often considered complex because it involves the relationship between bones, joints, muscles, and the health of the movement system. The type of research used is quantitative with a survey design. The research subjects consisted of 19 sixth grade students of SD Negeri Growong Kidul 02 who were selected through a total sampling technique. The research instrument was 10 diagnostic test items in a four-tier format (four levels) which included the level of answer, answer confidence, reasons, and reason confidence. The results showed that students' conceptual understanding was divided into three main categories: Concept Understanding (PK) of 48.42%, Misconception (M) of 50.53%, and Lack of Understanding (KP) of 1.05%. These findings indicate that misconceptions outweigh students' conceptual understanding, particularly regarding the mechanisms of antagonistic and synergistic muscles, the function and types of joints, and the relationship between nutrition and bone health. The use of a four-tier diagnostic test proved effective in accurately distinguishing students with a true understanding from those with misconceptions. This study concludes the need for innovative learning strategies and the use of concrete media to minimize misconceptions so that students have a strong foundation of scientific knowledge for the next level of education.

Mining companies are increasingly required to demonstrate environmental, social, and governance (ESG) accountability through sustainability reporting (SR). However, empirical evidence regarding the impact of SR on firm value in Indonesia’s mining sector remains inconsistent. This study aims to systematically examine the relationship between sustainability reporting and firm value using legitimacy theory as the conceptual framework. A Systematic Literature Review was conducted following the PRISMA 2020 protocol, employing narrative and thematic synthesis. Peer-reviewed articles published between 2018 and 2025 were retrieved from Google Scholar, Garuda Portal, and SINTA databases using relevant keywords. From 4,260 initial records, 11 studies met the inclusion criteria after screening, deduplication, and quality appraisal using an adapted CASP checklist. The findings reveal three dominant patterns: most studies report a positive effect of SR on firm value through improved transparency, corporate reputation, and investor confidence; several studies find no significant relationship due to short-term investor orientation; while a minority report negative effects associated with low disclosure quality and greenwashing concerns. Furthermore, the effectiveness of SR is influenced by disclosure quality, corporate governance, profitability, and leverage. This study implies that sustainability reporting can enhance firm value when disclosures are credible, consistent, and material, supporting legitimacy theory and encouraging alignment with the GRI 14: Mining Sector 2024 standard.

This study examines the relationship between Corporate Social Responsibility (CSR) disclosure and tax avoidance, with CEO Overconfidence considered as a moderating factor. The research focuses on non-cyclical consumer goods companies listed on the Indonesia Stock Exchange during the 2022-2024 period. Using annual and sustainability reports, the analysis employs multiple linear regression and moderated regression analysis (MRA). Robust standard errors based on the Newey-West method are applied to ensure reliable estimation. The results indicate that CSR disclosure does not have a significant direct effect on tax avoidance. However, CEO Overconfidence significantly moderates the relationship between CSR disclosure and tax avoidance, highlighting the role of executive behavioral characteristics in corporate tax decisions. These findings suggest that CSR disclosure alone is insufficient to explain firms’ tax avoidance behavior without considering managerial traits. The study contributes to the literature by integrating behavioral perspectives into tax avoidance research and emphasizing the importance of executive oversight in aligning CSR practices with responsible tax behavior.

The banking sector plays a strategic role in supporting financial system stability and capital market development. Market performance, reflected through stock returns, represents investor confidence in a firm’s prospects and sustainability. In recent years, investors have increasingly considered non-financial factors such as intellectual capital and corporate social responsibility in evaluating firm value. However, empirical findings regarding the effect of these factors on market performance remain inconsistent, particularly in the Indonesian banking sector. This study aims to examine the effect of intellectual capital and corporate social responsibility on market performance of conventional commercial banks listed on the Indonesia Stock Exchange during the 2021–2024 period. This research employs a quantitative approach using secondary data obtained from annual reports and sustainability reports. Intellectual capital is measured using the Value Added Intellectual Coefficient method, while corporate social responsibility is measured using a disclosure index based on the Global Reporting Initiative. Market performance is proxied by stock returns. Data analysis is conducted using multiple linear regression with the Ordinary Least Squares approach. The results indicate that intellectual capital and corporate social responsibility have a positive and significant effect on market performance. These findings suggest that effective management of intangible assets and social responsibility disclosure can enhance investor perception and firm value. The results provide important implications for bank management in formulating value-enhancing strategies and for investors in making investment decisions.

This study investigates the determinants of capital structure within the healthcare industry, focusing on the influence of asset structure, profitability, and company size. Given the capital-intensive nature of healthcare—characterized by significant investments in medical technology and infrastructure—understanding how these firms balance debt and equity is critical for financial sustainability and operational growth. Using a quantitative approach, this research analyzes a panel dataset of healthcare companies listed on the Indonesian Capital Market from 2018 to 2023. Furthermore, the capital structure is quantified by the debt-to-equity ratio. Meanwhile, asset structure, profitability, and company size are measured by the ratio of fixed assets to total assets, return on assets, and the natural logarithm of total assets, respectively. Moreover, the data are analyzed using multiple linear regression, supported by the classical assumption testing. As a result, asset structure has a significant positive impact on capital structure, aligning with the static trade-off theory. Conversely, profitability demonstrates a significant negative relationship with capital structure, supporting the pecking order theory. Finally, company size positively affects capital structure, indicating that larger firms have greater access to debt financing. These findings suggest that healthcare managers should optimize their asset utilization and internal reserves to maintain an efficient capital structure that supports long-term healthcare delivery and investor confidence.

Social emotional development in early childhood is an important foundation for children's psychological and social functioning in later stages of development. This process is greatly influenced by the quality of interactions within the family environment, including the level and quality of the father's involvement in parenting. Although various studies show that fathers play a significant role in shaping children's emotional regulation, independence, and social competence, studies that systematically integrate the role of fathers within the framework of psychosocial and sociocultural development theory are still relatively limited. This study aims to critically analyze the role of fathers in shaping the emotions and socialization of early childhood based on the perspectives of Erik Erikson's psychosocial development theory and Lev Vygotsky's sociocultural theory. This study uses a qualitative approach with a Literature Study Review (LSR) method of reputable national and international journal articles, academic books, and scientific proceedings published in the period 2020–2025. The data were analyzed through thematic synthesis and conceptual analysis. The results of the study show that consistent, responsive, and supportive father involvement contributes significantly to the development of emotional regulation, self-confidence, social initiative, and adaptive social interaction skills in children. These findings confirm the relevance of Erikson and Vygotsky's theories and provide theoretical and practical implications for the development of family parenting patterns and early childhood education policies that encourage optimal father involvement.
