Abstract

The reliance on manual procedures in village administrative services continues to create significant operational challenges, including slow document issuance, high rates of clerical errors, and insufficient mechanisms for verifying the authenticity of official documents. This study aimed to design and implement an Intelligent Agent–Based Village Certificate Service System with Digital Signature Support at Hilimbosi Village Office, Sitolu Ori District, North Nias Regency, North Sumatra. The system was developed by following the Waterfall software development model, using Laravel (PHP) as the backend framework, MySQL as the relational database management system, and OpenSSL/PKI for digital signature operations. A rule-based intelligent agent was integrated into the system to automate the validation of application data and to initiate document generation without requiring repeated manual intervention from clerical staff. Digital signatures based on the RSA-2048 algorithm and the SHA-256 hashing function were implemented to guarantee the authenticity and integrity of electronically issued certificates. Evaluation results demonstrated that the system reduced the average document processing time from two to three working days to under ten minutes, decreased the data error rate from 12% to below 2%, and received positive feedback from participants during User Acceptance Testing (UAT). This research contributes a replicable integration model combining intelligent agent technology and digital signature mechanisms within a village-level public administration context.
