Abstract

Abstract: Sistem Informasi Sumberdaya Terintegrasi (SISTER) is a system that integrates services within the scope of higher education resources and data integration with the Higher Education Database (PDDIKTI). This study aims to evaluate usability using the Heuristic Evaluation questionnaire, Usability Testing in the Lean UX phase, and ISO 13407 Evaluation in the final testing phase. The distribution of the questionnaire resulted in 676 responses, with 397 samples used and involving 3 evaluators in Usability Testing during the Lean UX phase. In the final phase, the evaluation was conducted according to ISO 13407 standards, involving 9 respondents to test the prototype using task scenarios. The evaluation results showed an average score of <1200 and a mean score of <3, indicating a low level of user satisfaction with the system. Additionally, a TCR value of <65% also indicated that the system's interface was considered fair or average by users. On the other hand, the Usability Testing results identified improvements related to redundant pop-up messages and over-engineering of outline buttons in the prototype. This list of issues served as a reference for compiling recommendations and design improvements based on the 10 usability heuristics. After making improvements, the ISO 13407 evaluation results achieved a score of 80.89%, indicating a Good qualification.

Abstract

Tuberkulosis (TBC) merupakan permasalahan kesehatan global, dengan Indonesia menempati urutan kedua sebagai negara dengan beban kasus tertinggi di dunia. Di Provinsi Lampung, pengendalian TBC menghadapi tantangan distribusi kasus yang tidak merata dan sistem pemantauan yang belum mampu menyajikan pemetaan tingkat kerawanan wilayah. Penelitian ini bertujuan merancang dan mengimplementasikan arsitektur backend Sistem Informasi Tuberkulosis berbasis Web-GIS untuk memetakan tingkat kerawanan berdasarkan parameter epidemiologi, sosiodemografi, dan lingkungan. Pengembangan sistem menggunakan metode Agile Development dengan kerangka kerja Scrum. Backend dibangun menggunakan Laravel dan MySQL serta menyediakan layanan Representational State Transfer (REST) API. Validasi dilakukan melalui Black Box Testing, sedangkan pengujian kinerja menggunakan K6. Hasil pengujian menunjukkan seluruh endpoint API berfungsi dengan tingkat keberhasilan 100%, serta server mampu mempertahankan waktu respons yang rendah hingga beban 300 pengguna virtual secara simultan. Arsitektur Web-GIS yang dihasilkan mampu menyajikan pemetaan interaktif sebagai pendukung pengambilan keputusan dalam mitigasi risiko TBC di tingkat daerah.
