The face is an important object in the biometric identification system. However, low image quality due to uneven lighting, noise, and variations in facial expressions can interfere with the accuracy of the recognition system. The study investigated the use of Convolutional Artificial Neural Network (CNN) combined with hybrid screening techniques to improve image quality, thereby improving the accuracy of facial recognition systems. Filters used include weight mean filtering, median filtering, Contrast-Limited Adaptive Histogram Equalization and gaussian filtering, wavelet filtering. The pre-processed image was then trained using image denoising measurements of the Structural Similarity Index, Mean Squared Error, and Peak Signal to Noise Ratio. The main objective of this study is to evaluate the best filtration combination to produce high accuracy in face classification. The datasets used were 55 classes and 100 images per class. The inceptionV3 architecture model is used for classifications with a number of epochs of 10. Evaluation was carried out on a facial data set with an 80%:20% scheme. The results of the experiment showed that the hybrid method produced the best performance with 94.5% validation accuracy, 94.2% precision, and 94.6% recall, an increase of +1.4% compared to baseline. The (original) baseline itself recorded 93.1% validation accuracy, 92.8% precision, and 93.2% recall. In addition, the loss graph shows that the pre-process model has faster and more stable convergence than the non-pre-processing model. These results confirm that the application of preprocessing, especially the hybrid approach, is able to improve the accuracy and stability of the model in image classification tasks.

The development of information technology encourages the need for efficient and mobile systems, especially in the small business sector such as playgrounds. This research aims to design and develop an Android-based Financial Information System at Krustyzone Playground to overcome the obstacles of manual recording, report delays, and lack of real-time data. The method used is Rapid Application Development (RAD), which allows a fast development process through design iterations and direct feedback from users. The system was developed using the CodeIgniter framework and MySQL database, and modeled with UML (Use Case Diagram, Activity Diagram, and Class Diagram). The implementation results show that the system is able to record income and expenses, display real-time financial reports, and manage users with different access rights. Tests through the Black Box Testing method prove that all functions run as expected. Validation by users shows the application is easy to use, efficient, and responsive. In conclusion, this system supports more accurate, secure, and structured financial management, as well as being an appropriate technology solution in assisting businesses in making decisions based on actual data.

The increasing reliance on digital platforms in education highlights the importance of website usability for supporting academic and administrative activities. This study evaluates the usability of the State Junior High School 40 Palembang website using the System Usability Scale (SUS), a widely adopted and reliable method for measuring user experience. Data were collected from 50 respondents representing students, teachers, and administrative staff through observations, documentation, and an online SUS questionnaire. The overall SUS score achieved was 75.6, which places the website in the Good usability category. Further analysis revealed differences among user groups: administrative staff rated the system as Excellent (82.5), teachers as Good but close to Excellent (78.0), and students as Good but with the lowest score (72.5). These variations indicate that user familiarity, task type, and device context strongly influence usability perception. Benchmark comparisons confirmed that while the website surpasses the global average threshold, improvements are required to elevate it to the Excellent level consistently across all groups. Key areas for enhancement include navigation consistency, user guidance, and mobile responsiveness. Addressing these aspects will ensure broader user satisfaction, higher efficiency, and alignment with best practices in educational website usability.

This study attempts to create interactive learning media using Articulate Storyline software forIndonesian language lessons in grade IV at Muhammadiyah 1 Elementary School in Purworejo Regency.The development was carried out in accordance with the Design Thinking Method, which consists of fivestages, namely empathize, define, ideate, prototype, and test. This study was motivated by the lowapplication of technology in learning and the need for media that can be used to increase students' interestin learning. Data was collected through observation and interviews with students and teachers. The learningmedia designed combines multimedia in the form of videos, audio, animations, and interactive quizzesbased on Google Forms that are directly connected to Google Spreadsheets for assessment. The media isstored in HTML5 and APK application formats so that it can be accessed via computers or smartphones.The results of the pilot test showed that the learning media developed was categorized as highlyeffective with an average effectiveness score of 4.34 based on the signs of learning interest according toSlameto (2011), which consist of the elements of interest, involvement, enjoyment, and attention. Therefore, this learning media can be used as an alternative solution to improve the quality of interactive Indonesian language learning in elementary schools.

Lecturers at UIN Jurai Siwo Lampung faced significant challenges in schedule management due to the lack of a centralized system, leading to frequent agenda conflicts and coordination inefficiencies. This research aimed to develop a functional agenda management application and evaluate the effectiveness of the Scrum method in this context. The software development process utilized the Scrum framework, emphasizing iterative sprints to adaptively handle changing user requirements. The results showed that the developed application successfully minimized scheduling overlaps through automated conflict detection features. Additionally, the Scrum method proved effective in accelerating the development cycle and ensuring the product met specific user needs. This study contributes a practical solution for enhancing academic productivity and offers empirical insights into implementing Agile methodologies within educational institutions.
