Development of a Web-based Community Marketplace System to Enhance the Competitiveness of Community Enterprises

Abstract

This study aimed to design and develop an online community marketplace system, evaluate its technical performance, and analyze its impact on the business performance of community enterprises. The study employed a Research and Development (R&D) approach. The research instruments included the developed online community marketplace system, a five-point Likert scale questionnaire, and performance testing using Apache JMeter. The results indicated that the system successfully supported product management, ordering, payment processing, and order tracking functions. The system achieved a response time ranging from 1.20 to 1.80 seconds and an error rate of less than 1% under the specified testing environment. In addition, the system was capable of supporting concurrent users efficiently. Regarding business impact, the findings revealed that average revenue increased by approximately 40%, operating costs decreased by approximately 20%, and the number of customers increased by approximately 80%. Although the results of the paired samples t-test did not show statistically significant differences (p > 0.05) due to the limited sample size used for business impact analysis (n = 3), the findings demonstrated a clear trend toward improved business performance. The study highlights that integrating both technical and business evaluations provides a concrete explanation of the relationship between information system performance and business outcomes in the context of community enterprises.
