FOTOREDUKSI BESI Fe3+ MENGGUNAKAN EKSTRAK DAUN KAYU MANIS (Cinnamomum burmanii) ABSTRAKTelah dilakukan penelitian tentang fotoreduksi besi Fe3+ menggunakan ekstrak daun kayu manis (Cinnamomum burmanii) dengan bantuan cahaya fluorescent 65 watt. Penelitian ini dilaksanakan pada bulan Juli – September 2017, bertempat di Laboratorium Biokimia Jurusan Kimia; Laboratorium Penelitian Jurusan Farmasi; dan Laboratorium UPT Terpadu Universitas Sam Ratulangi, Manado. Serbuk daun kayu manis diekstraksi secara refluks dengan metanol: 40; 60; dan 80%. Kandungan total fenolik; flavonoid; dan tanin ditentukan dengan reagen Folin-Ciocalteu; AlCl3; dan vanilin-HCl. Untuk kandungan besi tereduksi diukur dengan pembentukan kompleks besi(II)bipiridin. Hasil yang diperoleh menunjukkan bahwa ekstrak metanol: 40; 60; dan 80% memiliki kemampuan dalam mereduksi besi. Untuk ekstrak metanol 60% mempunyai efek fotoreduksi besi yang baik dimana kandungan besi(II) yang terbentuk sebesar 63,833 mg/L dengan waktu penyinaran selama 2 jam, dibandingkan ekstrak dengan konsentrasi pelarut metanol lainnyaKata Kunci: Daun Kayu Manis, Fenolik, Flavonoid, Tanin, Fotoreduksi Besi Fe3+ IRON PHOTOREDUCTION USING CINNAMON LEAF EXTRACT (Cinnamomum burmanii) ABSTRACTA study of Fe3+iron photoreduction has been done using cinnamon leaf extract (Cinnamomum burmanii) with the aid of 65 watt fluorescent light. This research was conducted in July - September 2017, held at Biochemistry Laboratory of Chemistry Department; Research Laboratory of Pharmaceutical Department; and the Integrated UPT Laboratory of Sam Ratulangi University, Manado. The cinnamon leaf powder is extracted by reflux with methanol: 40; 60; and 80%. Total phenolic content; flavonoids; and tannins are determined by Folin-Ciocalteu reagents; AlCl3; and vanilin-HCl. For reduced iron content is measured by the formation of iron(II)bipyridine complex. The result showed that methanol extracts: 40, 60: and 80% had ability in reducing iron. Methanol extract 60% had good iron photoreduction effect in which the iron(II) content was formed at 63.833 mg/L with irradiation time for 2 hours, compared to extract with other methanol solvent concentration.Keywords: Cinnamon Leaf, Phenolic, Flavonoid, Tannin, Iron Photoreduction
