Abstract

This study aims to design and develop a web-based e-commerce information system for creative services at Cahaya Kreativ using the Rapid Application Development (RAD) method, addressing the company's lack of an integrated digital platform for managing service orders, portfolios, consultations, and online payments. The RAD method was chosen due to its emphasis on speed, prototyping, and close user collaboration—making it more suitable than traditional methods like Waterfall for projects requiring rapid development and ongoing user input in a dynamic service environment. The system was built using React.js for the frontend, Express.js for the backend, PostgreSQL as the database, Tailwind CSS for UI design, and Midtrans integration as a payment gateway. The development process included two iterations covering requirement analysis, system design (use case diagram, sequence diagram, class diagram, ERD), implementation, and testing through Blackbox Testing and User Acceptance Testing (UAT). Results indicate that the system operates according to specifications and has received positive user feedback. It is expected to enhance Cahaya Kreativ’s operational efficiency, expand market reach, and improve the digital experience for customers ordering creative services online, while also supporting streamlined business processes, data consistency, and increased user engagement through responsive and interactive features. Stakeholder involvement throughout the development ensured the system closely matched real business requirements, resulting in a comprehensive digital solution that enhances customer satisfaction and operational performance through technology-driven innovation.

Abstract

Tingginya volume ulasan pengguna aplikasi kesehatan digital belum dimanfaatkan secara optimal untuk memahami aspek spesifik yang memengaruhi pengalaman pengguna. Penelitian ini bertujuan menganalisis sentimen berbasis multi-aspek pada ulasan aplikasi MySiloam menggunakan metode BERTopic untuk ekstraksi aspek dan SVM One-vs-One untuk klasifikasi sentimen. Sebanyak 2.657 ulasan dikumpulkan dari Google Play Store dan App Store rentang 2019–2025, disaring menjadi 1.699 ulasan setelah preprocessing. BERTopic dijalankan dengan perbandingan tiga algoritma clustering (HDBSCAN, BIRCH, K-Means) dan klasifikasi sentimen dibandingkan dalam dua skenario yaitu pendekatan dua tahap dan klasifikasi gabungan. K-Means dengan stemming menghasilkan tiga aspek layanan utama dengan kualitas topik terbaik, sementara pendekatan dua tahap menghasilkan F1-score tertinggi 89,53%, membuktikan bahwa kombinasi BERTopic dan SVM OvO efektif sebagai solusi otomatis analisis sentimen berbasis aspek pada ulasan aplikasi kesehatan digital berbahasa Indonesia.
