Abstract

This study aims to determine the influence of environmental cost and environmental performance towards company’s value. This study also examines the moderating effect of managerial ownership and institutional ownership on environmental cost and environmental performance towards company’s value. The object of this research is the participants of PROPER assessment that participates three years consecutively from year 2019-2021 that also listed in Indonesia Stock Exchange (IDX). The data analysis technique used in this study are the multiple linear regression and residual test. The results are: (1) environmental cost has negative and no significant influence towards company’s value, (2) environmental performance has positive and significant influence towards company’s value, (3) managerial ownership has moderating effect only on environmental cost relationship towards company’s value, and (4) institutional ownership has moderating effect only on environmental cost relationship towards company’s value. The theoretical implication is managerial and institutional ownership can strengthen environmental cost disclosure towards company’s value. The practical implications are the board of directors must consider optimum ownership structure to monitor and ensure that environmental cost disclosure is mandatory and make sure the operation of the companies is all according to the PROPER assessment standards. The government must establish a policy that obliges the publicly traded companies to disclose the environmental cost completely.

Abstract

This study aims to build a model of insurance company value based on revenue growth and operating expenses with Return on Equity (ROE) as a mediating variable. The study was conducted on six insurance companies listed on the IDX during the period 2020–2024 with a quantitative approach using SEM-PLS. The background of the study is the fluctuation of financial performance, especially the mismatch between revenue growth and equity efficiency and firm value. The results of the analysis show that revenue growth has a significant positive effect on firm value, both directly and through ROE. Conversely, operating expenses have a significant negative effect on firm value and are also mediated by ROE. ROE is proven to be a significant mediating variable in this relationship. The coefficient of determination (R²) value of 0.982 for firm value indicates that the model has a very strong ability to explain the variance of firm value. Meanwhile, R² for ROE of 0.566 indicates a moderate influence of the two independent variables. This study emphasizes the importance of increasing revenue and operational efficiency as a strategy to strengthen firm value and investor confidence.

Abstract

This study aims to analyze the effect of tax literacy, tax socialization, and the implementation of the Core Tax Administration System on tax compliance among Micro, Small, and Medium Enterprises (MSMEs) in Semarang. MSMEs play a significant role in Indonesia’s economy; however, their level of tax compliance remains relatively low, creating challenges for optimizing tax revenue. Therefore, understanding the factors that influence compliance is essential. This research employs a quantitative approach using primary data collected through questionnaires distributed to MSME taxpayers in Semarang. The sampling technique used is purposive sampling, with criteria including active MSME actors who possess a Taxpayer Identification Number (NPWP). Data were analyzed using multiple linear regression to examine the relationship between independent variables tax literacy, tax socialization, and the Core Tax Administration System and the dependent variable, tax compliance. The results indicate that all three independent variables have a positive and significant effect on MSME tax compliance. The implementation of the Core Tax Administration System has the strongest influence, followed by tax literacy and tax socialization. These findings suggest that both behavioral factors (knowledge and awareness) and structural factors (system efficiency and accessibility) play important roles in shaping compliance behavior. In conclusion, improving MSME tax compliance in Semarang requires an integrated approach that enhances tax literacy, strengthens tax socialization programs, and ensures the effective implementation of digital tax systems. This study contributes to the existing literature by providing empirical evidence on the combined effects of these variables in a local context. The findings are expected to support policymakers in designing more effective tax strategies and improving overall tax administration.
