Abstract

This research is motivated by the conventional marketing process of woven fabric at the Lawo Lio MSME in Rateweo Village, Ndori District, Ende Regency, which limits the reach of its products. In addition, sales data management and transaction recording are still carried out manually, making the process less effective and potentially causing recording errors. These conditions indicate the need for a web-based system that can support marketing activities and more systematic sales data management. This study aims to design and develop a web-based e-commerce information system that can help expand marketing reach, facilitate transaction processes, and improve the effectiveness and organization of sales data management at Lawo Lio MSME. The research uses a qualitative method with a descriptive-analytical approach. The system is developed using the Agile method, consisting of planning, implementation, testing, documentation, deployment, and maintenance stages. System analysis and design use a Data Flow Diagram (DFD) to describe the process flow and an Entity Relationship Diagram (ERD) to describe relationships among entities in the database. The system is developed using PHP, JavaScript, and MySQL, while system functionality is tested using the Black Box testing method. The result is a web-based e-commerce information system that provides features for managing customers, products, orders, payments, deliveries, and reports. The system integrates the Naïve Bayes algorithm to support product-search classification and Collaborative Filtering to provide product recommendations based on user preferences. The testing results show that the main system features operate according to the specified requirements. Therefore, the developed system can support the marketing process and the management of woven-fabric sales data more effectively and systematically.

Abstract

Dapoer J Cake is a home-based culinary business in Ende Regency that sells birthday cakes, dry cakes, birthday pudding, and fruit salad. The marketing and sales process is still carried out through social media and direct communication, while transaction recording is still manual. This may lead to recording inaccuracies, delays in transaction report preparation, and less optimal online marketing reach. This research aims to design and build a web-based e-commerce information system to support promotion, ordering, payment confirmation, transaction management, and sales reporting at Dapoer J Cake. The research uses a descriptive qualitative approach with data collection techniques through observation, interviews, and documentation. System development uses the Waterfall method, while testing uses Black Box Testing. The system was built using PHP, MySQL, HTML, CSS, Bootstrap, JavaScript, and XAMPP. The system provides three access roles: Admin, Owner, and Customer.The test results show that the main features function according to the functional requirements. This system helps Dapoer J Cake manage sales and customer service in a more structured manner and supports the online marketing and sales process.

Abstract

Bandung Shoes Store is a footwear retail business that still uses a manual sales system and relies on physical stores. This condition causes limitations in reaching customers, suboptimal promotions, and poorly structured transaction data management, which risks errors in sales report preparation. This research aims to design and build a web-based sales information system as a promotional medium and a means for online product ordering at Bandung Shoes Store. The research uses a descriptive qualitative approach with data collection techniques through observation, interviews, and literature review. System development uses the Waterfall method, which includes analysis, design, implementation, and testing. The system was built using PHP, MySQL, HTML, CSS, and JavaScript. Testing was conducted using the Black Box Testing method. The research result is a web-based sales information system that provides a product catalog, online ordering features, payment options (bank transfer, QRIS, COD), promo information, customer reviews, and structured data and sales report management. Based on Black Box testing of 7 main scenarios, all functions ran validly with a 100% success rate. This system is expected to improve transaction efficiency, expand promotional reach, and increase the number of customers at Bandung Shoes Store.

Abstract

Penerbit Nusa Indah is a business engaged in the sale of books and religious items in Ende Regency. In its sales process, Penerbit Nusa Indah still uses a conventional system, in which customers must come directly to the store or place orders manually through sales staff. This condition results in transaction records still being managed manually, limited product information available to customers, and a sales report recapitulation process that requires considerable time. This study aims to design and develop a Web-Based E-Commerce System to Improve Sales Efficiency at Penerbit Nusa Indah. This study uses a descriptive qualitative method with data collection techniques including observation, interviews, documentation, and literature review. The system was developed using the Waterfall method, which consists of requirements analysis, system design, implementation, testing, and maintenance. Data analysis was conducted using a descriptive qualitative approach, while system testing employed the Black Box Testing method to ensure that the system functions properly according to the specified requirements. The results show that the developed web-based e-commerce system can make the sales process more structured and computerized, facilitate customers in obtaining product information and placing orders online, and assist administrators in managing product data, orders, customers, transactions, and sales reports. The testing results indicate that the main functions of the system operate according to the predefined testing scenarios and requirements.
