Abstract

Yamani Lautan Berkah Jambi is one of the private companies engaged in ship agency services by serving inter-island sea freight services (domestic), export and import. There is no good HRM/Staff and is considered very less than optimal where the process is still manual and the number of employees available. As for the obstacles that are often faced in the HRM/Staff process ranging from the process of hiring new employees, employee data updates, leave application processes, warning letters, duty letters, and the creation of employee pay slips that are still done manually with recording / creation using agenda books and Ms. Word / Ms. Excel that causes these files often damaged and lost so that it takes a long time when needed. The purpose of this research is to analyze and design Web-Based Employee Information Systems at PT. Yamani Lautan Berkah Jambi for the problems that are being faced. Data collection is done by interview method to the director and HRD section. In addition, system modeling methods using UML (Unified Modelling Language) include: usecase diagrams, activity diagrams, and class diagrams and Balsamiq Mockups to design user interfaces. The output of this research is in the form of a Design or Prototype of a Web-Based Employee Information System at PT. Yamani Lautan Berkah Jambi

Abstract

The timely graduation of students is a key metric in evaluating the academic effectiveness of higher education institutions. However, accurately identifying students at risk of delayed graduation remains challenging due to imbalanced data distributions and the instability of single-model prediction approaches. This study proposes an optimized ensemble-based machine learning system for predicting on-time graduation among university students. The model integrates C4.5, K-Nearest Neighbor (KNN), and Random Forest algorithms through a hard voting classifier, which is further optimized using Particle Swarm Optimization (PSO) to determine the most effective weighting configuration. To address class imbalance, the Synthetic Minority Over-sampling Technique (SMOTE) is implemented, ensuring balanced representation between timely and delayed graduates. A dataset of 809 student academic records from Universitas Sains dan Teknologi Indonesia (USTI) was used, and performance was evaluated using 5-fold cross-validation. The proposed ensemble model achieved an average accuracy of 93.70%, a precision of 0.94, a recall of 0.93, and an F1-score of 0.94, outperforming each individual classifier. These results confirm that the combination of ensemble learning, PSO-based optimization, and data balancing effectively improves both accuracy and model stability. The findings highlight the system’s potential as a reliable decision-support tool for educational institutions to anticipate delayed graduations and improve academic supervision strategies.

Abstract

Digital transformation in human resources (HR) functions encourages organizations to replace manual administration with web-based HR information systems to improve data integration, security, and decision-making speed. However, implementing HR systems that still rely on hardcopy files or spreadsheets faces various challenges, such as the risk of data loss, inconsistent updates, weak access control, and delays in HR services. From a software engineering perspective, the prototype method is considered effective in addressing requirement uncertainties because it allows user involvement through continuous iteration and feedback. This study aims to (1) design and implement an HR information system development algorithm using the prototype method and (2) quantitatively evaluate the impact of prototyping iterations on system quality, including usability, security, and flexibility, as well as its impact on the effectiveness of HR processes. The study used a quantitative approach with descriptive analysis based on a Likert scale to measure users' perceptions of system quality. The results showed that prototyping iterations positively contributed to improving system quality and supported the effectiveness of HR services, particularly in accelerating administrative processes and reducing operational errors. These findings reinforce the role of the prototype method as a relevant development approach for web-based personnel information systems.

Abstract

Kegiatan pengabdian ini bertujuan untuk meningkatkan efektivitas, akurasi, dan transparansi pengelolaan administrasi di panti asuhan melalui penerapan sistem informasi digital berbasis web. Selama ini, pendataan anak asuh dan donatur dilakukan secara manual sehingga sering menimbulkan masalah seperti duplikasi data, keterlambatan pelaporan, kesalahan pencatatan, serta kurangnya transparansi dalam pemanfaatan donasi. Melalui kegiatan ini, tim pengabdian melakukan analisis kebutuhan, perancangan, implementasi sistem, serta pelatihan penggunaan kepada pengurus panti. Sistem informasi yang dibangun mencakup fitur pengelolaan data anak asuh, pencatatan donatur, histori donasi, laporan keuangan sederhana, dan dashboard visual. Hasil kegiatan menunjukkan bahwa sistem informasi digital mampu meningkatkan efisiensi kerja pengurus, meningkatkan transparansi informasi kepada donatur, serta mendukung pengelolaan panti secara lebih terstruktur dan profesional. Dengan demikian, implementasi sistem informasi terbukti efektif sebagai bentuk pemberdayaan panti asuhan menuju tata kelola yang lebih modern, akuntabel, dan berkelanjutan.
