Abstract

Gereja Kristen Indonesia (GKI) Maleo Raya menghadapi tantangan dalam pengelolaan administrasi jemaat yang masih bergantung pada pencatatan manual, sehingga menimbulkan risiko redundansi data, kehilangan arsip, serta keterlambatan dalam penyusunan laporan. Kegiatan pengabdian masyarakat ini bertujuan merancang dan menerapkan sistem informasi administrasi berbasis web responsif untuk meningkatkan efisiensi, akurasi, dan keamanan pengelolaan data gereja. Pengembangan sistem menggunakan metode Waterfall melalui tahapan analisis kebutuhan, perancangan, implementasi, dan pengujian. Sistem dilengkapi autentikasi One-Time Password (OTP) guna memperkuat keamanan akses dan mendukung kemudahan penggunaan bagi staf Kantor. Hasil implementasi menunjukkan bahwa aplikasi mampu mengelola database jemaat, mencatat sakramen, serta menghasilkan laporan statistik secara otomatis, dengan peningkatan kualitas layanan administrasi lebih dari 90%. Digitalisasi administrasi yang aman dan mobile-ready ini menjadi langkah strategis bagi gereja dalam mewujudkan pelayanan yang lebih efisien, responsif, dan transparan.

Abstract

Accessing civil engineering project documentation can be challenging when information needs to be retrieved quickly and conveniently in the field. This study aims to implement a mobile Knowledge Management System (KMS) application incorporating a Hybrid Search mechanism to support project documentation retrieval. The system was developed using the Waterfall method, which consists of requirements analysis, design, implementation, testing, and maintenance. The Hybrid Search mechanism combines an AI-based recommendation approach, which relies on rule matching and civil engineering domain-specific terminology, with keyword-based searching using SQL LIKE. The recommendation process involves query preprocessing, including case folding, tokenization, stopword removal, and synonym/domain expansion, followed by ranking based on project information matching scores. The recommendation results are then integrated with keyword search and given priority in the ranking process. Black-box testing results indicate that the search functionality and related features operate as expected. This study delivers a search mechanism that helps users retrieve civil engineering project documentation based on relevant terminology and project information matching.
