Abstract

Delta compression uses the previous block of bytes to be used as a reference in the compression process for the next blocks. This approach is increasingly ineffective due to the duplication of byte sequences in modern files. Another delta compression model uses the numerical difference approach of the sequence of bytes contained in a file. Storing the difference value will require fewer representation bits than the original value. Base + Delta is a compression model that uses delta which is obtained from the numerical differences in blocks of a fixed size. Developed with the aim of compressing memory blocks, this model uses fixed-sized blocks and does not have a special mechanism when applied to file compression in general. This study proposes a compression model by developing the concept of Base+Delta encoding which aims to be applicable to all file types. Modification and development carried out by adopting a dynamic block size using a sliding window and block header optimization on compressed and uncompressed blocks giving promising test results where almost all file formats tested can be compressed with a ratio that is not too large but consistent for all file formats where the ratio compression for all file formats obtained between 0.04 to 12.3. The developed compression model also produces compression failures in files with high uncompressed blocks where the overhead of additional uncompressed blocks of information causes files to become larger with a negative ratio obtained of -0.39 to -0.48 which is still relatively small and acceptable.

Abstract

The purpose of this research was to analyze the role of profitability in moderating the relationship green accounting, environmental performance, and total asset turnover on firm value in the 2019-2023 food and beverage subsector. All food and beverage companies listed on the Indonesia Stock Exchange (IDX) in that period became the research population. The purposive sampling technique resulted in 80 companies. Analyzed were using Descriptive Statistics, Classical Assumption Tests, Hypothesis Testing, and Moderated Regression Analysis (MRA).The result show that green accounting has a negative and significant effect on firm value, while environmental performance has a positive and significant effect.Total asset turnover does not significantly affect firm value. Furthermore, profitability is proven to moderate the relationship between green accounting and environmental performance with firm value but does not moderate the effect of total asset turnover. Based on these findings, green accounting plays a role in influencing firm value, although it is not the primary factor determining investors assessments. The implementation of environmental performance is more widely perceived as a form of social responsibility and sustainability that enhances public trust and market value. Meanwhile, efficiency in asset utilization through total asset turnover is not considered a key determinant in increasing firm value.

Abstract

Fraud disclosure is a crucial issue in public sector accountability that requires effective mechanisms to detect and prevent fraudulent practices. This study aims to examine the impact of forensic accounting, whistleblowing systems, and investigative audits on fraud disclosure, and to test the role of professional skepticism as a moderating variable. Using a quantitative approach with an associative research design, the population comprised all 183 employees of the Financial and Development Supervisory Agency (BPKP) of North Sumatra Province. Through a saturated sampling method, 76 valid responses were collected using questionnaires. Data were analyzed with multiple linear regression and moderated regression analysis (MRA). The results show that forensic accounting, whistleblowing systems, and investigative audits have a positive and significant effect on fraud disclosure. However, professional skepticism does not moderate the relationship between these variables and fraud disclosure. These findings suggest that the application of forensic accounting, whistleblowing mechanisms, and investigative auditing can strengthen fraud disclosure practices, but auditors’ professional skepticism does not significantly enhance this relationship. This study contributes to the existing literature by underlining the limitations of professional skepticism as a moderating factor in fraud disclosure, particularly within public sector audit institutions in Indonesia

Abstract

This study aims to determine the effect of profitability, firm age, and capital structure on audit delay, with firm size as a moderating variable, in manufacturing companies listed on the Indonesia Stock Exchange for the 2019–2023. The sample was obtained through purposive sampling, with companies meeting the research criteria. The population in this study was 282 manufacturing companies listed on the Indonesia Stock Exchange. In comparison, the sample in this study amounted to 40 companies over the 5 years of research, so the total sample in this study wa 200 samples. This study is an associative study with a quantitative approach. The data used are secondary from the companies' annual financial reports. The data analysis techniques used were multiple linear regression and Moderated Regression Analysis (MRA). The study's results indicate that profitability and firm age have a negative effect on audit delay, while capital structure does not significantly impact audit delay. The results of the MRA test indicate that firm size moderates the impact of profitability and firm age on audit delay. In contrast, firm size does not moderate the effect of capital structure on audit delay.

Abstract

Financial Accounting Standards for Micro, Small and Medium Entities (SAK - EMKM) in Indonesia are absolutely necessary. With SAK - EMKM, MSME actors can compile a financial report that can describe the actual situation of the business situation carried out by MSME players. By having a financial reporting, MSME actors can see whether their business is sufficient with their own capital or must be supplemented with outside capital, such as loans from banks. Therefore, having a standardized financial reporting is a must because it is a requirement for banks to obtain business loans. This research is a literature study to see the relevance of Accounting Standards for Micro, Small and Medium Entities in Indonesia for the sustainability of Micro, Small and Medium Entities in Indonesia amid the Economic Crisis.
