Anemia is a condition in which the number of red blood cells or the hemoglobin concentration in the blood falls below normal levels. One preventive effort to reduce the risk of anemia is ensuring adequate intake of essential minerals, particularly iron (Fe) and magnesium (Mg). Basil leaves (Ocimum basilicum L.) were selected as the research object because they are widely consumed by the community, while scientific information regarding their mineral content, especially iron and magnesium, remains limited. This study employed a descriptive research design to determine the levels of iron (Fe) and magnesium (Mg) in basil leaves collected from several growing locations in Loa Janan Ilir District. The concentrations of Fe and Mg were analyzed using Atomic Absorption Spectrophotometry (AAS) following sample digestion. The results showed that the highest iron (Fe) concentration was found in samples from the Moeis Hasan location, reaching 1.62 mg/g, whereas magnesium (Mg) concentrations were relatively consistent across all study locations. Differences in Fe levels among locations were presumed to be influenced by environmental conditions and land management practices. In contrast, Mg levels exhibited only slight variation because magnesium is a secondary macronutrient that is generally available in sufficient quantities in the soil and is less affected by changes in soil pH, fertilizer type, or the addition of organic matter.
