Pengembangan Sistem Dokumen Akreditasi Program Studi D4 TRPL Berbasis Website dengan Penerapan BM25 dan Inverted Index
Accreditation documents in the D4 Software Engineering Technology Study Program are dispersed across devices and locations, complicating retrieval, version control, validation, and completeness monitoring. This study develops web-based SIDA TRPL using Waterfall, Laravel 13, SQLite, an in-memory Inverted Index, and BM25 (k1 = 1.5; b = 0.75). Black-box testing showed 7/7 scenarios successful (100%). On five documents and five multi-term queries, BM25 ranked the target first in all cases (5/5; Hit@1 = 100%), while literal SQL LIKE retrieved only 1/5 targets (20%). Role-based UAT accepted 12/12 scenarios (100\%). Nielsen inspection found eight heuristics fulfilled and two partially fulfilled, mainly undo/recovery and help/documentation. In the test environment, SIDA TRPL supports centralized document management, role-based validation, completeness monitoring, and relevance-oriented retrieval; production effectiveness requires further evaluation.
