Each indicator is scorched, the combination of these three indicators produces a composite value for the FNSS which indicates the level of food vulnerability in an area. The results showed that in all sub-districts in Denpasar City were classified as high-risk areas, characterized by indicators of high deficit serelia food production ( r < 0.95), indicators of malnutrition and deficiency (under weight) is classified as safe ( < 15%), and indicators of food utilization are classified as safe (pre-PF and PF-1 < 20%).
