%X Similarity of regions (provinces in Indonesia) in producing the strategic food production were analyzed based on seven serial data sets and each one consists of nine food commodities weighted by number of population. The food data sets were compiled from Food Security Agency, The Ministry of Agriculture, while the population data was collected from The Statistics Indonesia of the Republic of Indonesia. Main sources of variability on each data set were identified on loading values basis extracted using biplot (Gower and 1996). The similarity of the food production patterns to the overall data sets were evaluated using generalized Procrustes rotation (gPr). Results of this research showed there are two groups of production system pattern. In the first group, there are five commodities dominating the first two components, i.e., paddy, maize, soybean, peanut, and cassava−, while in the second group, there are six commodities dominating the first two components, i.e., paddy, maize, chicken eggs, beef, peanuts, and cassava. Hence, the gPr was applied in both groups separately. Applied the gPr to the first group showed there are seven commodities dominating the first two consensus axis −paddy, maize, soybean, peanut, cassava, chicken egg, and sweet potatoes. This means the chicken eggs and sweet potatoes are considered as common variances. Applied the gPr to the second group indicated that the commodities dominating the two consensus axis are same with ones dominating the first two components. But, if the third consensus axis is assumed important then soybean seem as common source of variability in the second group. Consequently, the similarities of the data sets in each group was established based upon identified sources of variability.
