RANCANG BANGUN SISTEM INFORMASI PENJUALAN BERBASIS WEB DENGAN FRAMEWORK CODEIGNITER: UPAYA PERBAIKAN EFISIENSI OPERASIONAL

Abstract

Changes in the way a trading business works often become urgent only when manual transaction records begin to cause problems. At TOKO XYZ, sales, stock, and reports are still handled manually and separately, making data prone to errors, stock difficult to monitor, and reports slow to produce. This study aims to design a web-based sales information system using the CodeIgniter framework so that these processes become more organized and efficient. The study employs a Research and Development (R&D) approach covering problem identification, data collection, design, validation, revision, and product testing. Data were gathered through observation, interviews, and documentation. System design is supported by flowcharts, DFD, ERD, and database normalization, while implementation uses PHP with CodeIgniter, MySQL, and HTML, CSS, and JavaScript. Testing is carried out through black-box testing and limited user trials to ensure that the main functions meet the requirements. The resulting system covers sales transaction recording, stock management, and sales report generation. The trial results indicate that the workflow becomes more concise, sales data are easier to trace, and reports can be generated without repeated manual recaps. Thus, the use of CodeIgniter in this system contributes positively to TOKO XYZ’s operational efficiency and provides room for further feature development.
