ABSTRAK &#13;
-bentonit telah berhasil dilakukan menggunakan&#13;
metode solid state reaction dari bahan baku pasir besi pantai Syiah Kuala, Banda&#13;
Aceh dan bentonit dari Kuala Dewa, Aceh Utara. Sintesis ?-Fe&#13;
 dilakukan&#13;
dengan cara ekstraksi pasir besi menggunakan asam klorida dan presipitasi&#13;
menggunakan NH&#13;
4&#13;
OH pada pH 6. Komposit ?-Fe&#13;
2&#13;
O&#13;
-bentonit dipreparasi dengan&#13;
mencampurkan ?-Fe&#13;
2&#13;
O&#13;
3&#13;
3&#13;
 dan bentonit dengan perbandingan 4:1 menggunakan ball&#13;
mill selama 2 jam. Karakterisasi pasir besi dan komposit ?-Fe&#13;
2&#13;
O&#13;
-bentonit dengan&#13;
XRD menunjukkan bahwa fasa dominan yang terdapat dalam pasir besi adalah&#13;
magnetit (Fe&#13;
3&#13;
O&#13;
4&#13;
) sedangkan dalam komposit adalah hematit (?-Fe&#13;
3&#13;
) dan silika&#13;
(SiO&#13;
). Aktivitas fotokatalitik komposit diuji pada degradasi zat warna indigo&#13;
carmine pada berbagai variasi kondisi pH, massa fotokatalis, konsentrasi awal zat&#13;
warna dan waktu radiasi. Hasil yang diperoleh menunjukkan bahwa aktivitas&#13;
fotokatalitik komposit ?-Fe&#13;
2&#13;
2&#13;
O&#13;
-bentonit tertinggi diperoleh pada kondisi pH&#13;
larutan 1, massa fotokatalis 250 mg dan konsentrasi indigo carmine 10 ppm&#13;
dengan persen degradasi mencapai 91,480% setelah diradiasi dengan sinar ultra&#13;
violet (UV) selama 60 menit. Komposit ?-Fe&#13;
3&#13;
2&#13;
O&#13;
-bentonit memiliki aktivitas yang&#13;
lebih tinggi menggunakan radiasi sinar matahari (92,083%) dibandingkan dengan&#13;
radiasi sinar ultra violet.&#13;

ABSTRACT&#13;
 &#13;
&#13;
Preparation of ?-Fe&#13;
2&#13;
O&#13;
3&#13;
3&#13;
-bentonite composite has been successfully performed by&#13;
solid state reaction method by using iron sand from coastal of Syiah Kuala, Banda&#13;
Aceh and bentonite from Kuala Dewa, North Aceh as raw materials. The ?-Fe&#13;
&#13;
was extracted from iron sand using hydrochloric acid and precipitated using&#13;
ammonium hydroxide at pH 6. The ?-Fe&#13;
2&#13;
O&#13;
-bentonite composite was prepared by&#13;
mixing ?-Fe&#13;
2&#13;
O&#13;
3&#13;
3&#13;
 and bentonite at 4: 1 ratio using ball mill for 2 hours. The XRD&#13;
results showed that the dominant phase of iron sand was magnetite (Fe&#13;
), while&#13;
in ?-Fe&#13;
2&#13;
O&#13;
3&#13;
-bentonit composites the dominant phase were ?-Fe&#13;
2&#13;
O&#13;
. The&#13;
photocatalytic activity was tested on degradation of indigo carmine dye at various&#13;
condition of pH, photocatalyst mass, initial dye concentration and irradiation time.&#13;
The results showed that the highest photocatalytic activity of ?-Fe&#13;
3 &#13;
-bentonite &#13;
(%D = 91.480%) was obtained at pH of solution 1, 250 mg photocatalyst mass&#13;
and concentration of IC 10 ppm after irradiated with UV light for 60 minutes. The&#13;
?-Fe&#13;
2&#13;
O&#13;
-bentonite composite has higher activity in sunlight irradiation (92,083%)&#13;
than ultra violet rays.&#13;
