Abstract

The aim of this research was to determine the effect of soaking and concentration of potassium bicarbonate on the growth of A. flavus in peanut (Arachis hypogea L.). seeds The method used in this research is an experimental method using Completely Randomized Design (RAL) which consists of 2 factors. The first factor was the time consisting of 2 levels (soaking 3 time and 6 time) and the second factor was the concentration of potassium bicarbonate comprising 3 treatment levels (conscentration 0, 1 and 2%). So, there were 6 treatments and each treatment made 4 replications. The parameters observed were, pH, water content, total damaged seeds and fungus of A. flavus. Data from microbiological test observation were analyzed using descriptive method. The observation of chemical and physical tests were analyzed by analysis of variance at 5% significance level using software co-Stat. If there was any significant difference in the result of chemical and organoleptic test results, then the further test was done using the test of Honestly Significance Difference (HSD). The results showed that the interaction of immersion and KHCO3 concentration did not significantly affect pH value, damaged seed and water content. Soaking time 6 hours with a concentration of 2% KHCO3 could reduce A. flavus of> 1.74 log. Keywords: peanut seeds, soaking time, the concentration of KHCO3, A. flavus
