Komparasi Produktivitas Pengarang Jurnal Cancer Research dan Jurnal Circulation Tahun 2013-2022 Menggunakan Hukum Lotka

Abstract

The purpose of this study was to compare author productivity and the conformity of the frequency distribution of author productivity in the Journal of Cancer Research and the Journal of Circulation. This research is comparative research using a quantitative approach. The research sample was determined by using the disproportionate stratified random sampling method. The results of productivity calculations using Lotka's Law show that the percentage of authors contributing to one article in the Journal of Cancer Research for the straight count method is 97.1%. At the same time, that in the Journal of Circulation is 94.6%. The percentage for the complete count and adjusted count methods in the Journal of Cancer Research is 90.3%, while that in the Journal of Circulation is 83.8%. The Kolmogorov-Smirnov test results show a significant difference between the theoretical frequency distribution of Lotka's Law and the frequency distribution of article authors in the Journal of Cancer Research. This is indicated by the maximum deviation value (Dmaks) being more significant than the critical value at the real level of 0.05, namely precisely in the complete count and adjusted count methods with a Dmaks value of 0.0310 and a critical value of 0.0117. The study results show that by looking at the contribution of article authors, authors from the Journal of Circulation are more productive than those from the Journal of Cancer Research, with the highest article contribution being 28 articles by Deepak L. Bhatt from the Journal of Circulation. The conformity of the frequency distribution of author productivity in the Circulation Journal does fit Lotka's Law of author productivity. This is shown in the straight count, complete count, and adjusted count methods, while the Cancer Research Journal only fits in the straight count method.
