This study presents a comprehensive analysis of user experience (UX) in student assistant application using the Five Planes Method, structured approach UX design. Focusing on specific needs students, this research seeks to enhance usability and overall satisfaction application. The paper begins with detailed review related works design analysis, highlighting various methodologies frameworks field. methodology adopted involves which includes Strategy Plane, Scope Structure Skeleton Surface Plane. Each plane contributes unique aspect process, ensuring user-centric development approach. employs System Usability Scale (SUS) for empirical evaluation, validating efficacy Method improving experience. results indicate significant enhancement provides valuable insights into importance structured, user-focused development, particularly educational domain.

This paper proposed two evaluation metrics of the tamper coincidence in a block map design for image watermarking. These are called Tamper Coincidence Block Ratio (TCBR) and Density (TCBD). A occurred authentication self-recovery when recovery data original location were tampered with simultaneously. high limits inpainting's capability to recover region, leading an imprecise recovered image. The ratio density may significantly affect final quality. Previously, researchers mentioned their experiment but did not evaluate it any metrics. They evaluated robustness technique based on quality using Peak Signal-to-Noise (PSNR) Structural Similarity Index Measure (SSIM). coincidences primarily affected by implemented researcher. Thus, TCBR TCBD provide valuable insight into design's effectiveness preventing coincidence. experimental result shows that values inversely proportional value leads low Therefore, this will help effective minimizing obtain highest
