ery of literacy greetings to visitors. In practice, greetings are commonly delivered manually or through conventional bells, leading to inconsistency and dependence on staff availability. This study was conducted at the Amir Machmud Library, Ministry of Home Affairs, Jakarta, Indonesia, aiming to design and evaluate a Python-based scheduled audio alarm system for automated literacy greetings. An applied experimental method was employed, including system design, Python script development, scheduling configuration using Windows Task Scheduler, and direct system testing on a library computer connected to ceiling speakers. The system requires initial execution via Command Prompt (CMD) when the computer is powered on, after which it operates automatically according to predefined schedules. Testing results demonstrate that the system performs scheduled audio playback accurately and operates stably without further manual intervention. The findings indicate that the proposed system provides a practical and efficient solution to enhance service consistency and support a structured and conducive literacy environment in the library.

Abstract:This study aims to apply the Analytic Network Process (ANP) method as a decision support tool in determining the eligibility of education grant recipients in North Sumatra Province. The background of this research arises…
from the large number of grant applicants compared to the available budget, as well as the absence of clear and objective evaluation standards. The ANP method was chosen because it allows the interdependence between assessment criteria such as institutional feasibility, performance and achievement, social and educational impact, and accountability and transparency to be analyzed comprehensively. Data were obtained through interviews, documentation, and observation at the North Sumatra Provincial Education Office. The results of the ANP model show that the criterion with the highest weight is accountability and transparency (0.44), followed by social and educational impact (0.31). Among the three alternatives, community-based education foundations (A2) obtained the highest total weight (0.30), indicating that they are the most eligible recipients of education grants. The implementation of the ANP-based decision support system produces valid and consistent ranking results (CR < 0.1), enabling faster, fairer, and more transparent decision-making. Therefore, the ANP method contributes significantly to improving governance, objectivity, and accountability in the distribution of education grants in North Sumatra Province.
