Rice (Oryza sativa L.) is one of the staple foods widely consumed by Indonesian people. They usually have rice as the biggest portion on their diet, therefore rice becomes the main source of nutrients of Indonesian people mainly for those whom live in Java Islands. Although rice is known to contain various minerals, but the minerals level are varied based on differences in geographic region associated with soil quality. Hence, quantity and quality of minerals content of rice from different regions of the world are particularly important to be characterized. The present aim of the study was to assess the composition of mineral of rice from different geographical regions in Java Islands, Indonesia using nuclear analytical techniques i.e. Neutron Activation Analysis method... Quality control of data analysis was assessed using SRM NIST Rice Flour 1568a and gave good results with accuracy (% bias) ≤5% and precision (%CV) less than 10%. The essential elements contents such as Fe, Zn, and Se were quantified and found in the range of 2.8–60.9, 2.48–28.8, and 0.01–2.17 mg/kg respectively, while for the toxic elements, Cr and Co in rice are also quantified and found in the range of 0.03–1.24 and 0.003–0.59 mg/kg, respectivelyThe elemental concentrations in rices from Java Island followed the order Zn>Fe>Se>Cr>Co. It also found that rices from East Java Province have higher concentrations of Fe and Se, while the highest mean of Zn concentration was found in the rices from Jakarta province. The daily intake of those elements in rices give significant contribution to their RDA values. These results of mineral contents in rice hopefully can be used as one of references for estimating daily nutritional intake status of especially Javanese people.
