Abstract

This study aims to find out about Information Technology management at Muhammadiyah University of Palembang and to get right advice in managing Information Technology from the University level to the Study Program. Regarding benchmarks in Information Technology Governance use the Cobit 5 framework with the Evaluate, Direct and Monitor domains. Monitoring and evaluation was carried out using a questionnaire distributed to lecturers and employees at the Muhammadiyah University of Palembang and the researchers did observations on the management of higher education information technology governance. Based on the questionnaire result, the highest gap occurs in sub domain 4, which is 3.65 while the observation result towards the capability level is at level 3 with a value of 56.67%, the sub domain ensuring resource optimization has the highest capability value of 66.67%. Based on the data obtained using the EDM domain, the University of Muhamadiyah Palembang has to set Standard Operating Procedures (SOP) and Work Instructions (IK) so every five processes can run well to create good IT governance.

Abstract

Diabetic retinopathy (DR) is a diabetes-related condition that can cause vision impairment or vision loss. Accurately identifying the level of DR from retinal fundus images is crucial for early detection. However, poor image quality often degrades classification performance. This study proposes an approach that integrates gamma correction-based image enhancement with a Batch Normalization–Visual Geometry Group (BN-VGG) architecture for multiclass DR severity classification. Gamma correction is applied to improve image contrast, while BN-VGG enhances training stability and feature representation. The proposed method categorizes DR into five classifications: normal, mild, moderate, severe, and proliferative. The enhanced images achieved PSNR of 30.85 and SSIM above 0.86, indicating improved visual quality. The model achieved accuracy at 0.97, sensitivity at 0.92, specificity at 0.98, F1-score at 0.92, Cohen's Kappa at 0.90, and G-Mean at 0.97. The innovative aspect of this study is the incorporation of gamma correction with BN-VGG architecture, demonstrating that image enhancement can significantly improve multiclass DR classification performance without increasing model complexity. The study's results indicate the proposed method's effectiveness for accurate & reliable DR severity classification

Abstract

Employee attendance and task management are important elements in maintaining organizational productivity, accountability, and operational efficiency. Conventional attendance systems, such as manual recording and fingerprint devices, still face several limitations including fraud potential, inaccurate data recording, and lack of flexibility for field employees. This research aims to design and develop an integrated Android-based attendance and task management application by utilizing Global Positioning System (GPS), Location Based Service (LBS), visual attendance validation, and real-time task monitoring features. The system was developed using the Rapid Application Development (RAD) approach combined with Agile Development to accelerate system implementation through iterative processes and continuous user feedback. The application integrates attendance recording, GPS location validation, employee task assignment, progress monitoring, and deadline notifications into a single platform. System testing was conducted using the Black-box Testing method to evaluate application functionality and reliability. The results show that the developed system successfully performs core functions such as login, GPS-based attendance, task management, attendance reports, and task monitoring with a testing success rate of 94%. The system is also capable of reducing attendance manipulation through real-time location validation and activity monitoring mechanisms. This research contributes an integrated mobile solution that improves attendance accuracy, task transparency, work efficiency, and employee productivity in organizations with high workforce mobility.

Abstract

Information technology continues to grow in response to societal needs, including the education sector which increasingly depends on digital systems. One of the essential processes in school administration is the Admission of New Students (PPDB), which serves as the first stage of school services to the public. At PAUD TK Dharma Wanita Kebur Village, the PPDB process is still conducted conventionally, requiring parents or guardians to come directly to the school, resulting in inefficiencies in time, effort, and data management. This study develops a web-based PPDB information system as a solution to improve the accuracy, speed, and convenience of the admission process. The Waterfall method is used in system development, consisting of sequential stages including requirements analysis, design, implementation, testing, and maintenance. Data collection was conducted through literature studies and analysis of existing registration procedures. The designed system includes features such as user login, online registration, prospective student data input, validation, and automated registration processing. The final result is a web-based PPDB system that is expected to make the student admission process more efficient, structured, and accessible for both schools and prospective students, while supporting better data management in educational institutions.

Abstract

Mosques play a central role in Muslim community life, not only as places of worship but also as centers for social and financial activities, such as donations, alms management, and dissemination of mosque-related information. However, in the current era of rapid technological development, many mosques still rely on manual systems for financial management and information delivery, which are prone to recording errors, calculation inaccuracies, data loss, and limited transparency. This condition can reduce public trust and hinder effective mosque management. Therefore, technological innovation is needed to support transparent, accurate, and efficient mosque administration. This research aims to assist the management of Raudhatul Mukhlisin Mosque in improving the efficiency and accuracy of mosque financial data management through the development of a website-based information system. The system was developed using the Waterfall method, which includes requirement analysis, system design, implementation, testing, and maintenance. This study applies qualitative research methods with data collection techniques including observation and literature review. The developed system utilizes PHP, HTML, and MySQL, and system testing was conducted using the Black Box method. The results show that the proposed system facilitates data recording, financial reporting, and information access, while enhancing transparency and accountability for mosque administrators and worshippers.

Abstract

In the use of information technology, including the system of archiving incoming mails, outgoing letters are very important to support organizational development in terms of operational activities. This is because with the existence of an archiving system in an organization, it can speed up a work process and can make it easier to manage letters and make letters more organized and neat. The researcher sees that there are problems in the Sukamuda village letter filing system where at this time, the procedures applied to the management of incoming and outgoing letters in Sukamuda village, starting from receipt, storage, documentation, to letter verification, are all carried out conventionally. This research aims to make it easier to archive incoming and outgoing letters by developing a website-based archiving application . The research method used is the Development (R&D) method, observation data collection techniques and literature studies, the system development model used in this study is the Waterfall Model. Waterfall is one of the Software Development Life Cycles (SDLC) where software development activities start from specification, development, validation, and evolution and then divide it into phases and final testing using the Black Box method. With the implementation of this system, it is hoped that it can overcome problems in the application of letter archiving, especially at the letter stage in villages like to move.
