Fe is an important mineral that plays a role in the body’s metabolism. Fe functions as a form of hemoglobin, a catalyst for the conversion of beta-carotene to vitamin A, purine and collagen synthesis, antibody production, and detoxification of drugs in the liver. Fe in the body is automatically renewed by food, especially rice. To meet these needs, the minimum consumed rice contains Fe 26.1-78.2 ppm but in reality it is only around 9.4-16.2 ppm. Therefore, biofortification efforts are needed to increase the Fe content in rice. The purpose of this study was to determine the potential of Moringa leaves in increasing Fe uptake. The experimental design was factorial with Completely Randomized Design as the basic design, consisting of 2 factors: Liquid organic fertilizer (P0: no liquid organic fertilizer, P1: Moringa extract, P2: Moringa fermentation), Fertilizer concentration (K1:2 %, K2: 4 %, K3: 6 %, K4: 8 %). Data were analyzed by statistical analysis using ANOVA 95% significance level followed by Duncan Multiple Range Test 95% significance level. The results showed that the highest Fe absorption was in the P1K2 treatment (Moringa extract+4%) which was 8.31% or 90.25% compared to the control.
