Abstract

This study aims to evaluate the usability of an offline desktop library application developed using Java Swing and integrated with an iReport feature. The evaluation employed the System Usability Scale (SUS) using a descriptive quantitative approach. Data were collected from 28 respondents consisting of librarians and library administrators as the primary system users. The results show that the application achieved an average SUS score of 62.77, which falls into the marginal acceptability range, corresponding to Grade D and an “OK” adjective rating, and below the standard SUS benchmark score of 68. These findings indicate that the application adequately supports basic library operations but still exhibits usability limitations, particularly in interface consistency, user confusion, and reliance on technical assistance. Consequently, improvements in interface design and user experience are necessary to enhance the overall usability of the application.

Abstract

Distraksi digital menjadi tantangan utama produktivitas belajar mahasiswa. Berdasarkan survei terhadap 100 responden, 87,5% mahasiswa kesulitan mempertahankan fokus belajar dan 75% kesulitan mengelola tugas. Penelitian ini bertujuan merancang sistem informasi Ocus (On Focus Studies) yang mengintegrasikan Pomodoro Timer, task management, dan progress tracking dalam platform mobile. Metode pengembangan menggunakan Software Development Life Cycle (SDLC) meliputi perencanaan, analisis kebutuhan, desain sistem, dan rencana implementasi. Hasil perancangan menghasilkan lima fitur utama dengan dokumentasi Use Case Diagram, Activity Diagram, Class Diagram, dan desain UI berbasis React Native. Sistem dirancang untuk meningkatkan fokus belajar hingga 60% dengan mengurangi distraksi digital melalui teknik Pomodoro yang terintegrasi
