Abstract

The Electronic Immunization Monitoring and Logistics System (SMILE) is an information system designed to support the integrated management of immunization records and healthcare logistics. The successful implementation of such a system depends not only on its functionality but also on its usability, which significantly influences user satisfaction and acceptance. This study aims to evaluate the usability of the SMILE application using the PIECES framework—covering Performance, Information, Economy, Control, Efficiency, and Service—and the System Usability Scale (SUS). A descriptive quantitative approach was employed, with data collected through observations, a literature review, and questionnaire surveys administered to 56 users of the SMILE application at the Gorontalo Provincial Health Office. The results of the PIECES analysis indicate that all evaluation dimensions achieved the "Satisfied" category, with mean scores of 3.68 for Performance, 4.28 for Information, 4.36 for Economy, 4.26 for Control, 4.25 for Efficiency, and 4.25 for Service. The usability assessment using the SUS yielded an average score of 53, which falls within the "OK" adjective rating (score range: 51–67) and the "Marginal" acceptability category. According to the SUS grading scale, this score corresponds to Grade D, indicating that the application's overall usability requires improvement. Although users expressed satisfaction with the system's performance and service quality, the findings suggest that enhancements are still needed, particularly in terms of ease of use, navigation, and overall user experience. The findings of this study provide valuable insights and practical recommendations for developers to improve the quality and usability of the SMILE application, thereby supporting more effective adoption and use in healthcare services.

Abstract

This study aimed to optimize the marketing and sales processes of MSME processed products through the development of an Android-based information system using the User Centered Design approach. The identified problems indicated that most MSME actors still conducted marketing and sales activities conventionally, resulting in limited promotional reach, less effective transaction management, and difficulties for consumers in accessing product information. This research was conducted using the User Centered Design method, which focused on user needs and experiences through the stages of interviews, observations, needs analysis, system design, implementation, and application testing. The results showed that the developed information system was able to assist MSME actors in managing product data, conducting digital promotions, and recording sales transactions more effectively and systematically. The Android-based application provided convenience for the community and business actors to access product information and carry out promotions anytime and anywhere through smartphones. The implementation results demonstrated a 75% increase in the marketing and sales of MSME processed products after the application was utilized. Therefore, the developed information system was able to support the digital transformation of MSMEs and improve marketing effectiveness as well as product competitiveness in a broader market.
