Abstract

Abstract This research details the development of Android-based Attendance Application for D-III Accounting Lecturers (ABA DOA) using Appsheet platform and utilizing LATLONG() and DISTANCE() functions for location validation. The development method applied is Rapid Application Development (RAD). ABA DOA provides convenience for lecturers with a self-photo feature as proof of validation, while integrating GPS and Google Maps to validate the location of attendance. The application results show efficiency in academic management with an optimal level of security. The LATLONG() function is used to determine the location coordinate point, while DISTANCE() is used to measure the distance between the authorized coordinate point and the attendance location. This research highlights the importance of technological innovation in supporting academic activities and campus management. The conclusion of this research is that ABA DOA successfully optimizes the attendance process with a high level of validation and security, making a positive contribution to the efficiency and effectiveness of study program management.

Abstract

This research aims to prove whether there is an influence of environmental costs and carbon accounting on profitability performance of mining companies in Indonesia with environmental performance as a moderating variable. It is based on the emergence of research urgency as there is still a knowledge gap about environmental cost management and carbon accounting pratices which specifically affect profitability, especially in the mining sector which has unique challenges in its operations and environmental impact. This is causal, quantitative research and uses secondary data. There are 47 mining companies listed on the Indonesian Stock Exchange in 2021-2023 as a population. Research sample of 22 companies were selected using a purposive sampling technique with companies’ criteria that present financial reports for 3 consecutive years, earn profits during the 2021-2023 period and presenr a sustainable report for the preriod of 2021-2023. This research uses hypothesis data testing for logistic regression analysis using Eview 12 software. The results of data testing show that environmental costs have a positive and significant effect on profitability (H1 accepted). Carbon Accounting has a positive and significant effect on profitability (H2 accepted). Environmental performance has a significant effect moderates the relationship between environmental costs and profitability (H3 accepted) and Environmental performance has a significant effect moderates the relationship between carbon accounting and profitability (H4 rejected)

Abstract

The research investigates the impact of productive asset quality, liquidity, and profitability on risk management disclosure in Indonesian banking companies listed on the Indonesia Stock Exchange from 2017 to 2022. Utilizing Eviews 10 software, the analysis employs panel data regression, descriptive statistical tests, multiple linear regression, and moderation analysis. The sample comprises 22 banking companies, selected through random sampling, using secondary data. Findings indicate a significantly negative relationship between productive asset quality and risk management disclosure. Moreover, firm size amplifies this negative impact. In contrast, liquidity and profitability do not significantly influence risk management disclosure. Notably, firm size diminishes the significance of liquidity and profitability in the context of Indonesian banking companies. These results offer insights into the intricate dynamics of risk management disclosure and highlight the nuanced role of firm size in shaping these relationships.

Abstract

This Systematic Literature Review (SLR) examines the application of the E-Servqual theory developed by Parasuraman et al. (2005) within e-business research published from 2020 to 2025. The review highlights that the E-Servqual model continues to be theoretically robust and practically relevant in assessing electronic service quality amid rapid digital transformation. Across the selected studies, the dimensions of Efficiency, System Availability, and Privacy consistently emerge as the most dominant factors influencing users’ evaluation of digital service excellence. These dimensions are especially critical as businesses increasingly rely on online platforms to deliver services, manage customer interactions, and support technology-based accounting processes. Most of the reviewed studies adopt a quantitative research approach, with survey instruments used to capture user perceptions of electronic service quality. The collected data are predominantly analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM), demonstrating its popularity for measuring complex relationships between service quality dimensions and user satisfaction or behavioral intentions in digital environments. The consistent use of this analytical method also reflects the growing emphasis on empirical validation in e-business and digital accounting research. Overall, the findings of this SLR reinforce the position of E-Servqual as a flexible and comprehensive theoretical framework for evaluating service quality in technology-driven settings. Its adaptability allows researchers and practitioners to assess various digital platforms, including online marketplaces, financial technology services, and accounting information systems. Thus, E-Servqual remains an essential tool for understanding user experience and enhancing service performance in modern e-business ecosystems.  Keywords  : E-Servqual, Electronic Service Quality, E-Business, Digital Accounting, User Experience, SLR
