Kajian Bibliometrik terhadap Karakteristik Kepengarangan dan Artikel Pada Buletin Pertanian Perkotaan

Urban Farm DB summary

A bibliometric study of the Buletin Pertanian Perkotaan (Urban Agriculture Bulletin), published by BPTP Jakarta (Indonesia's agricultural technology assessment center) over its first six years, 2011–2016, examining author profession distribution, subject distribution, article distribution, citation currency, citation source distribution, author collaboration levels, and author productivity, using bibliometric methods and the Subramanyam formula for collaboration level. Across 2011–2016 the bulletin published 56 articles by 46 authors, both from within and outside BPTP Jakarta; researchers were the most common author type (25 people: 19 from BPTP Jakarta, 6 external), and agricultural cultivation was the leading subject with 25 articles. Article output peaked in 2013–2015, at 10 articles per year each. Citation currency needs improvement: per LIPI's 2012 guideline requiring cited references to be five years old or newer, the majority of references in the bulletin's articles—701 of them—were over five years old. By subject, socio-economic agriculture articles drew 43% of their citations from sources under five years old, while post-harvest articles were dominated (43.8%) by citations over ten years old. Citations from scientific journals accounted for only 46.5% of citation sources, well below LIPI's required 80% threshold.
