The Short Version
The journal's affiliation with Universitas Gadjah Mada is well-documented, but no available evidence confirms the specific article titled "Karakteristik Fisik dan Kimiawi Serta Teknik Konservasi Naskah Lontar" was ever published in it. Multiple authoritative databases and the journal's own site fail to surface any bibliographic record — no volume, issue, authors, or DOI — for this title. Topical plausibility and the possibility that unindexed archives might contain it do not constitute verification of publication.
