Abstract

This study aims to investigate the factors that influence carbon emissions disclosure in mining companies in Indonesia by considering the role of ownership concentration, the existence of a CSR Department, and company age as mediators. Data was collected from audited financial reports of mining companies listed on the Indonesia Stock Exchange during 2017-2021. The analysis method used is Path Regression with the AMOS 23.00 software tool. The research results show that ownership concentration does not significantly affect the disclosure of carbon emissions. This finding is based on agency theory, highlighting interest differences between managers and shareholders. The existence of a CSR Department has a positive and significant influence on carbon emissions disclosure. However, the CSR Department cannot mediate the relationship between ownership concentration and carbon emissions disclosure. Furthermore, company age plays a vital role as a mediator in the relationship between ownership concentration and carbon emissions disclosure, showing that the older the company, the higher the level of carbon emissions disclosure carried out, reflecting experience, deep understanding of stakeholder needs, and commitment company towards sustainable practices.

Abstract

Medical images, including MRI, CT, ultrasound, X-rays, and ECG, are crucial for diagnostics; however, they present significant data security challenges. This study introduces a novel watermarking technique that utilizes discrete wavelet transform (DWT), discrete cosine transform (DCT), and singular value decomposition (SVD) to enhance the security, confidentiality, and integrity of medical images. In addition, Run Length Encoding (RLE) is implemented for efficient compression, which significantly reduces data memory requirements. The proposed method demonstrated a notable improvement in the peak signal-to-Noise Ratio (PSNR), increasing by up to 5 dB compared to existing techniques, and achieved a file size reduction of 15-30%. These advances ensure that high-quality images consume less storage space while maintaining diagnostic integrity. The improved PSNR values indicate that the watermark remains imperceptible, making the proposed method highly effective for clinical applications. Compared to existing methods, the proposed method offers enhanced robustness against digital attacks and better image quality preservation. These findings support the secure and efficient handling of medical image data, thereby promoting their use in clinical environments.

Abstract

Penelitian ini bertujuan untuk menganalisis penerapan Peraturan Pemerintah Nomor 23 Tahun 2018 yang mengatur pajak penghasilan atas pendapatan dari usaha yang diterima atau diperoleh wajib pajak dengan peredaran bruto tertentu. Fokus utama penelitian ini adalah sektor Usaha Mikro, Kecil, dan Menengah (UMKM) yang bergerak di bidang digital marketing di Jakarta. Dengan menggunakan pendekatan studi kasus, penelitian ini mengevaluasi pemahaman, kepatuhan, serta dampak dari kebijakan pajak tersebut terhadap beban pajak dan kelangsungan usaha. Data dikumpulkan melalui wawancara, observasi, dan dokumentasi dari beberapa perusahaan digital marketing skala UMKM di Jakarta. Hasil penelitian menunjukkan bahwa meskipun PP 23 Tahun 2018 menawarkan kemudahan administrasi dan tarif pajak yang lebih rendah, masih ada hambatan dalam pelaksanaannya, terutama terkait kurangnya pemahaman dari wajib pajak mengenai ketentuan perpajakan serta kesulitan dalam melakukan pencatatan transaksi dengan akurat. Oleh karena itu, perlu adanya peningkatan edukasi perpajakan dan dukungan teknis dari pemerintah agar kebijakan ini dapat berjalan lebih efektif dan mendukung pertumbuhan UMKM di era digital.

Abstract

In this study, the development of the Mean-based method proposed by Goyal and Kumar will be carried out by changing the initial cluster center determination step, which was originally based on the origin point O (0,0), to be replaced with the arithmetic mean. To assess the performance of the proposed method, it will be compared with the Global K-means method and the Mean-based K-means method. In this study, the performance of these methods will be measured using the Davies-Bouldin Index, and the significance of the proposed method will be measured using the Friedman Test. This study proposes a method of Improving K-Means Performance through Initial Center Optimization based on Second Global Average for Clustering Osteoporosis Diagnosis of lifestyle factors. Evaluation of K-Means performance through Initial Center Optimization based on Second Global Average with DBI measurements. The targeted experimental results of this study include improving the performance of K-means optimized through the initial center based on Second Global Average. From the results of nine experiments with the number of clusters [2,3,4,5,6], it can be seen that the method proposed in this study has the same superior performance compared to the Mean Based method and compared to the Global K-means method.

Abstract

This research endeavors to scrutinize the ramifications of Good Corporate Governance (GCG) on the financial performance of companies accredited by the Indonesia Stock Exchange (IDX). GCG functions as a pivotal framework in corporate stewardship, principally aimed at augmenting investor confidence and fostering superior financial outcomes. Employing a quantitative paradigm, this study draws upon secondary data derived from the financial statements and annual reports of IDX-listed corporations spanning the period from 2019 to 2023. The independent variables under examination encompass the proportion of independent commissioners, institutional ownership, and the functionality of the audit committee, whereas the dependent variable, financial performance, is operationalized through Return on Assets (ROA), Return on Equity (ROE), and Tobin’s Q. Empirical findings reveal a discernible and significant impact of GCG on corporate financial performance. More precisely, the proportion of independent commissioners and the efficacy of the audit committee exhibit a positive association. with ROA and ROE. Conversely, institutional ownership demonstrates a more nuanced and somewhat inconsistent relationship with the different metrics of financial performance. These insights carry substantial weight for regulatory bodies, corporate leadership, and the investment community, underscoring the imperative to reinforce robust corporate governance practices as a prerequisite for achieving sustainable financial prosperity.
