Abstract

The rapid advancement of information technology has accelerated digital transformation across various business sectors, including Micro, Small, and Medium Enterprises (MSMEs). Despite the widespread adoption of digital marketplaces, many MSMEs continue to face challenges related to high transaction fees, limited ownership of customer data, and dependence on third-party platforms, which may reduce long-term business profitability and sustainability. Therefore, developing an independent e-commerce platform has become a strategic alternative to strengthen business competitiveness and improve operational efficiency. This study aims to design, develop, and evaluate a website-based e-commerce platform for Sibgah Boutique using the Rapid Application Development (RAD) approach as a digital transformation strategy. The research employed a Research and Development (R&D) methodology consisting of planning, design, development, implementation, and evaluation stages. Data were collected through observation, interviews, documentation, and usability testing using the USE Questionnaire involving boutique owners, employees, and customers. Furthermore, the economic feasibility of the developed system was assessed through Cost–Benefit Analysis (CBA). The findings indicate that the developed platform successfully facilitates product management, inventory monitoring, and online transaction processing while reducing dependence on third-party marketplaces. The usability evaluation demonstrates that the system falls within the "Very Useful" category, indicating a high level of user acceptance and satisfaction. Moreover, the CBA results reveal that the projected economic benefits exceed the development costs, confirming the financial feasibility of the platform. The integration of usability evaluation and economic analysis provides a comprehensive assessment of the system's effectiveness in supporting MSME digital transformation. These findings reinforce the importance of independent e-commerce platforms in enhancing operational performance, increasing customer engagement, improving business profitability, and promoting sustainable digital business development.

Abstract

This study analyzes the effectiveness of monetary policy transmission channels in controlling inflation in Indonesia using a Vector Autoregression model. Monthly data from December 2005 to March 2025 include the Federal Funds Rate, Bank Indonesia’s policy rate, inflation, and exchange rate. The results show that Bank Indonesia’s policy rate responds to inflationary pressures within two to four months, while exchange rate movements affect imported inflation within three to seven months. The Federal Funds Rate has fluctuating effects on the exchange rate and inflation, emphasizing the importance of monitoring monetary spillovers. Granger causality results indicate that the BI Rate is the only variable with significant predictive power for the exchange rate at the 5 percent level. Indonesian inflation exhibits strong short term persistence, with shocks remaining the main source of forecast error variance. Over six to ten months, shocks to the BI Rate and Federal Funds Rate jointly explain 20 to 30 percent of inflation variance. FEVD results show that exchange rate pass through is not dominant, although it remains relevant for mitigating imported inflation risks. These findings emphasize the need to accelerate monetary transmission, deepen domestic financial markets, and strengthen coordination between fiscal and monetary authorities to maintain price stability.
