Abstract

Kebutuhan akan sistem pelayanan yang cepat, efisien, dan mudah diakses mendorong sektor pariwisata untuk mengadopsi pendekatan digital, termasuk dalam proses registrasi pendakian gunung. Penelitian ini bertujuan merancang antarmuka pengguna (User Interface/UI) sistem registrasi online pendaki Gunung Sindoro melalui Basecamp Ndoro Arum dengan metode Prototyping. Metode ini dipilih karena bersifat iteratif dan berorientasi pada pengguna, memungkinkan perbaikan desain secara berkelanjutan berdasarkan umpan balik pengguna. Pendekatan penelitian yang digunakan adalah deskriptif kualitatif, dengan teknik pengumpulan data melalui observasi, wawancara, dan studi literatur. Proses pengembangan meliputi analisis kebutuhan, perancangan prototipe menggunakan Figma, evaluasi, dan penyempurnaan desain. Hasil menunjukkan bahwa metode Prototyping efektif dalam menghasilkan desain UI yang responsif, intuitif, dan sesuai dengan ekspektasi pengguna. Prototipe yang dikembangkan meningkatkan efisiensi registrasi sekaligus memperkuat pengalaman pengguna dalam mengakses layanan. Penelitian ini diharapkan menjadi referensi bagi pengembangan sistem registrasi daring berbasis UI/UX.

Abstract

The TOEFL test is an international standard for measuring English language ability. This research developed a web-based TOEFL examination system at the “Plug-in” Training Institute using the Scrum method to address the shortcomings of the old system, such as audio control, score accuracy, and insufficient detail in recording results. The data were collected through observation, interviews, and literature study. Scrum was applied in three sprints that focused on the listening section navigation, score calculation, and answer logging. Features for single audio playback, a timer, automatic score calculation, and a detailed results display were successfully implemented. Testing showed the system to be stable and accurate according to TOEFL standards. This system improves efficiency, fairness, and user experience in digital TOEFL examinations. Suggestions for development include broader testing, UI/UX optimization, a data export feature, and more detailed answer logging for analysis.
