Berita Harian feature of 24 Feb 1987 by I.A. Makmur Makka on the press then and now, tied to Indonesia's National Press Day and the PWI anniversary at Hotel Indonesia. Only the lead snippet was retrieved; it does not name S.K. Trimurti, and the sweep's Trimurti match is unverified. Little direct Gerwani relevance.
