Perancangan Dashboard Interaktif Untuk Visualisasi Data Penjualan Menggunakan Teknologi Big Data

Abstract

This study aims to design and develop an effective interactive dashboard for sales data visualization by leveraging big data technology. The ever-increasing volume of data necessitates more sophisticated solutions for business analysis, where static data visualization is no longer adequate. Using a descriptive-evaluative approach, this research designs a system that integrates Apache Spark for large-volume data processing and modern web technologies for the user interface. The result is a dashboard that not only displays key sales metrics in real-time through various charts but also empowers users with interactive features such as filtering and drill-down capabilities. Functionality and performance testing showed that the system could process millions of data rows with low latency. User evaluation confirmed a high level of satisfaction with the ease of use and clarity of the visualizations. This study thus proves that combining big data technology with a user-centered dashboard design can transform complex sales data into valuable business insights, accelerating decision-making and improving operational efficiency.
