ANALISIS BIBLIOMETRIKA MENGGUNAKAN HUKUM LOTKA PADA PRODUKTIVITAS PENULIS ARTIKEL BIDANG PERTANIAN DI INDONESIA
The purpose of this research is to know the author's productivity pattern of article in the field of agriculture in Indonesia 2006-2015 using Lotka’s Law. The data of this research were taken from national journal accredited by the Ministry of Research, Technology and Higher Education which can be accessed from http://www.kopertis12.or.id. From 2006-2015, it is found that there are 2650 authors and 4141 articles on Agriculture. Assessment author’s participation was done by using ‘straight count’.The Lotka theoretical value use the formula of yx=C/xn.. C is a constant and n is exponent. Based on the calculation with Lotka’s law, it is found that C=0.80773 and n= 2.81500. The result shows that the percentage of the authors giving contribution to 1 article is 80.77%. Test of Kolmogorov-Smirnov results shows that the maximum deviation is 0.08396 with critical value (with α = 0.05) 0.02642, it shows that the maximum deviation is bigger than critical value. Therefore, the null hypothesis is rejected and concluded that the dataset does not follow Lotka’s law (there is a significant difference between the Lotka’s law theoretic distribution and the distribution of article author in the field of Agriculture).
