EVALUASI PERFORMA APLIKASI PENGADUAN IRONCARE MENGGUNAKAN GTMETRIX UNTUK REKOMENDASI MAINTENANCE

Abstract

Digital complaint systems require fast, stable, and efficient website performance to ensure that users can access public services without technical barriers. Ironcare, also known as Imigrasi Cirebon Care, is a digital complaint system used by the Class I Immigration Office TPI Cirebon to support complaint submission, tracking, and follow-up. This study aims to analyze the performance of the Ironcare homepage and formulate maintenance recommendations based on a GTmetrix report. The research applies a descriptive quantitative method with purposive sampling on the Ironcare homepage. The data were collected from a GTmetrix report generated on April 28, 2026, using the Seattle, WA, USA test server, Chrome 142.0.0.0, and Lighthouse 12.6.1. The test results show that Ironcare obtained GTmetrix Grade B, Performance Score 85%, Structure Score 95%, Largest Contentful Paint 1.2 seconds, Total Blocking Time 0 ms, Cumulative Layout Shift 0.02, Fully Loaded Time 1.6 seconds, Total Page Size 266 KB, and Total Page Requests 7. These findings indicate that the initial access performance of Ironcare is good and lightweight. However, the Speed Index of 5.8 seconds and several Structure Audit findings show the need for maintenance on render-blocking resources, image dimensions, static asset caching, CDN utilization, unused CSS, image formats, and a 404 faviconrequest. This study contributes to performance mapping of an immigration digital complaint system and data-based maintenance recommendations.
