Abstract

This study underscores the importance of wound image segmentation in the medical world to speed up first aid for victims and increase the efficiency of medical personnel in providing appropriate treatment. Although the body has a protective function from external threats, the skin can be easily damaged and cause injuries that require rapid detection and treatment. This study used the K-Means clustering algorithm to segment the external wound image dataset consisting of three types of wounds, namely abrasion, puncture, and laceration. The results showed that K-Means clustering is an effective method for segmenting wound images. The greater the number of segments used, the better the quality of the resulting segmentation. However, it is necessary to take into account the specific characteristics of each type of wound and the number of segments used in order to choose the most suitable segmentation method. Evaluation using various metrics, such as VOI, GCE, MSE, and PSNR, provides an objective assessment of the quality of segmentation. The results showed that abrasion wounds were easier to segment compared to puncture wounds and lacerations. In addition, the size of the image file also affects the speed of program execution, although it is not always absolute depending on the characteristics of the image.

Abstract

In the digitalization era of banking, cybersecurity has become a critical priority as the frequency and sophistication of cyber-attacks rise. This study evaluates Bank DJX's cybersecurity maturity (a pseudonym), focusing on compliance with POJK PTI and SEOJK regulations on cyber resilience in commercial banks. Using a qualitative approach, it assesses inherent cybersecurity risks and the effectiveness of risk management. Findings show a maturity score of 2.1, indicating effective and satisfactory practices, alongside an inherent risk score of 1.9 with a narrow gap (+0.20), suggesting that while current controls address existing threats, the capacity to manage emerging risks remains limited without further enhancements. Given the rapidly evolving threat landscape, continuous improvement is essential. Aligned with recommendations, Bank DJX is well-positioned to strengthen its cybersecurity resilience to meet regulatory demands and proactively address future threats. This study offers empirical insights into cybersecurity practices in Indonesia's digital banking sector, underscoring the importance of regulatory compliance and proactive risk management.
