The research methodology employed experimental research and development (R&D) based on the System Development Life Cycle (SDLC) process. The research instruments included: (1) a meeting notification system using Google Calendar integrated with LINE Notify, (2) a system efficiency evaluation form, and (3) a user satisfaction questionnaire. The sample group consisted of 25 personnel from Lopburi Highway District 1, Nong Muang Highway Maintenance Unit, Highway Office 11, and three experts who evaluated the system efficiency. The statistical methods used for data analysis were mean and standard deviation. The research findings indicated that: (1) the system was able to record meeting schedules through Google Calendar and send notifications via the LINE application effectively; (2) the overall system efficiency was evaluated at a good level; and (3) user satisfaction with the system was rated at a good level (𝑥̄ = 3.91, S.D. = 0.76). The integration of Google Calendar with LINE Notify enhanced accuracy, reduced missed appointments, enabled advance reminders, saved time, and improved communication efficiency.
