Abstract

This study aims to cluster traffic violation data recorded by CCTV in the Sidoarjo area using the K-Means Clustering algorithm. The dataset used in this study was obtained from Sidoarjo Police, covering 43,055 traffic violation records in the period January 2023 to July 2024. The CRISP-DM approach is applied to ensure a systematic research flow, starting from problem understanding, data collection, to result evaluation. After the data selection and transformation stage, the dataset was processed into 14,386 data. Clustering was performed to divide violations into three categories based on severity, namely high, medium, and low. Evaluation of cluster quality using Silhouette Score showed the best result with a value of 0.9916 at k=9, indicating optimal cluster formation. The clustering results showed that the highest violation occurred in the category of “not using a seat belt” with 8,710 cases, while the moderate violation involved “not wearing a helmet” with 5,522 cases. This study confirms the effectiveness of the K-Means algorithm in clustering traffic violation data and provides valuable insights for the Sidoarjo Police Traffic Unit in designing more efficient traffic violation reduction programs.

Abstract

This study focuses on designing and developing an international program registration application using the User-Centered Design (UCD) approach. The UCD method is implemented to create an optimized user interface and experience, prioritizing the needs of both local and international students. The application replaces the previously used Google Form-based system, which had limitations in data security, database management, and selection process integration. The development process follows UCD principles, including context of use identification, user and organizational needs analysis, high-fidelity prototype design, and evaluation using the System Usability Scale (SUS). The initial evaluation resulted in an SUS score of 65 (Marginal High), which improved to 72 (Acceptable) after a redesign. The application is developed using Dart for the frontend and Firebase for the backend, ensuring flexibility in feature expansion. This solution enhances registration efficiency, improves the user experience, and supports multilingual and cross-device accessibility. Ultimately, this research contributes to technological innovation in international program management while strengthening the institution’s competitiveness in global higher education.

Abstract

Financial management is a core subject of the study program that must be mastered by students of the Sharia Financial Management study program. This course presents material about financial management in theory. Based on the results of initial observations that have been made, Sharia Financial Management students have not even tried to directly practice financial management using an information system in managing finances. This happens because several existing financial management information systems are closed systems so students cannot access the system. Therefore, this study proposes a financial management information system with the support of IoT technology as a simulation or practice medium for Sharia Financial Management study program students. The proposed method in this study uses Waterfall model. Based on the average value of TAM analysis, it is 81.72%, where this value is included in the Very Good for use to strengthen the Financial Literacy of Sharia Financial Management students.

Abstract

This study aims to classify attenuation quality in fiber optic networks using the K-Means algorithm. The classification model is designed to group data based on the characteristics of network parameters collected from field measurements. This research also compares the performance of models built with all features and those using selected features. The evaluation uses two main metrics, Sum of Squared Errors (SSE) and Silhouette Coefficient, to assess the quality of the clustering results. Testing shows that the use of selected features produces better clusters, with an SSE of 91.75 and a Silhouette Coefficient of 0.5923, compared to using all features, which results in an SSE of 101.98 and a Silhouette Coefficient of 0.4977. These results indicate that selecting the right features can positively impact cluster quality, although it is not the sole determining factor. Overall, K-Means has been proven effective in grouping attenuation quality, making it useful for supporting efficient fiber optic network maintenance and monitoring.

Abstract

New student admission is a very important process in higher education that requires fast, accurate, and organized information. At Bina Insani University, this process was previously done manually and using WhatsApp messaging services directly by the admin, which caused delays in response, repeated questions, and difficulties in managing registration documents. The purpose of this research is to build a new student admission information system that can speed up the registration process, reduce admin workload, and centralize registration documents digitally. This research uses the Extreme Programming (XP) method with data collection techniques through observation, interviews, and literature studies. This system is implemented using CodeIgniter with MySQL database and integrates real-time notifications via WhatsApp and Email using RabbitMQ architecture as a message broker. The results of the system implementation show that automatic notifications can improve the efficiency of information services, reduce repetitive questions, and speed up the response and document distribution process. The system also facilitates the search for registration documents with Google Drive integration. In conclusion, this system makes a significant contribution in improving the quality of new student admission services at Bina Insani University.
