Development of a Web-Based Electronic Medical Records Information System

Abstract

The Electronic Medical Record (EMR) system is a cornerstone of modern healthcare digitalization, enabling healthcare providers to store, retrieve, and manage patient information efficiently and securely. This study presents the design, development, and evaluation of a web-based EMR information system specifically tailored for primary healthcare centers (puskesmas) in Indonesia. The system was developed using the Laravel PHP framework for back-end logic, MySQL as the relational database management system, and Bootstrap 5 for a responsive front-end interface. Development followed the Software Development Life Cycle (SDLC) with an Agile approach, incorporating iterative sprints and continuous end-user feedback. Functional testing was conducted using the black-box method across 47 test cases covering six core modules, achieving a 100 % pass rate. System usability was assessed through the System Usability Scale (SUS) with 30 participants, yielding a mean score of 82.5, classified as 'Excellent'. The system implements role-based access control (RBAC), AES-256 data encryption, HTTPS enforcement, and comprehensive audit-trail logging. Compared with the previous paper-based workflow, the proposed system reduced record-retrieval time by 72.6 %, administrative workload by 61.2 %, and improved data-entry accuracy from 68 % to 95 %. These results demonstrate that the system is functional, secure, usable, and aligned with Indonesia's national health information system (SIKNAS) standards, offering a replicable model for resource-constrained healthcare settings
