Siti Nazwa Maulidiya — 2026-10-28

Perkembangan teknologi informasi mempercepat akses data kuliner, namun platform Blogger konvensional FoodStory memiliki keterbatasan pada fleksibilitas tata letak visual dan navigasi menu mobile yang kurang intuitif, sehingga penyampaian narasi filosofis kuliner Nusantara menjadi kurang optimal. Penelitian ini bertujuan merancang ulang antarmuka FoodStory menjadi prototipe aplikasi mobile yang elegan, minimalis, dan fungsional menggunakan perangkat lunak Figma. Metode penelitian yang digunakan adalah Design Thinking dengan pendekatan deskriptif komparatif melalui lima tahapan: empathize, define, ideate, prototype, dan testing. Hasil temuan menunjukkan bahwa implementasi desain high-fidelity dengan skema warna earth tone, struktur top navigation bar, dan sistem kartu berbasis grid pagination berhasil memotong waktu pencarian informasi resep secara signifikan serta meningkatkan kenyamanan visual. Kesimpulannya, transformasi antarmuka ini mampu meningkatkan nilai usability dan kepuasan interaksi pengguna secara optimal. Implikasi dari penelitian ini memberikan kontribusi praktis serta referensi bagi pengembang platform digital dalam menciptakan pengalaman visual yang menarik untuk pelestarian budaya pangan lokal.

Technological developments, particularly in the fields of financial technology and e-commerce, have transformed the way Indonesians conduct buying and selling transactions. This study aims to build an e-commerce website for Rizstore, a clothing retailer. The website was developed using WordPress as a Content Management System (CMS) combined with the WooCommerce plugin to manage the product catalog, shopping cart, payment methods, and order management. WordPress was chosen because of its open source nature, ease of use, and flexibility for customization. The system development method used was the Rapid Application Development (RAD) method. This method was chosen because it allows for rapid development by utilizing existing software components, allowing the system to be immediately implemented and customized according to needs without having to go through the development process from scratch. The result of this study is a functional e-commerce website that can be used to market products online. This research is expected to serve as a reference for small business owners who want to start selling digitally without having to have a physical store first, as well as provide academic contributions in the field of web-based information system development.
