The data analysis technique used is Analysis of Variance (ANOVA) at a significance level of 5%. The treatment given to Bima local shallots was 1 treatment without refrigeration and 4 pre-cooling treatments, each of which was repeated 4 times to obtain 20 experimental units. The parameters measured are: 1) plant height; 2) number of leaves; and 3) leaf diameter. The results of this study indicate that, on the parameters of plant height, number of leaves, and leaf diameter it is stated that fcount
