Synthesis of Ferrous Fumarate from Indonesian Iron Sand and In Vivo Body Weight Gain Test in Rats

Iron deficiency anemia (IDA) is a health problem in Indonesia. Prevention and treatment of IDA carried out by giving fortified foods oral iron therapy. Both can use ferrous fumarate which made with reacting bivalent disodium fumarate. Bivalent be obtained from sand This study aims to synthesize Indonesian sand, Malang, Sukabumi, Cianjur area, determine its absorption through vivo body weight gain test male Wistar white rats (Rattus norvegicus). First, was synthesized reaction sulfate, the highest content, Sukabumi Second, conducted 3 rat groups (negative control, sulfate group, respectively) monitored for two weeks. The results showed that successfully as brownish red-orange fine powder yield 62.17 ± 1.66 %. In addition, suggested group similar (35.1%) compared those (30.6%), indicating possibility
