Abstract

STUDI PERBANDINGAN EFEK FOTOKATALISIS Fe2O3-TiO2 HASIL EKSTRAKSI ILMENIT
BANGKA DAN P-25 DEGUSSA UNTUK APLIKASI PENGOLAHAN LIMBAH CAIR TPA
CILOWONG. Telah dilakukan penelitian penurunan kadar BOD5, COD, dan TDS dari lindi sampah tempat
pembuangan akhir (TPA) Cilowong dengan menggunakan katalis Fe2O3-TiO2 dari hasil proses ekstraksi ilmenit
Bangka Indonesia dan TiO2 P-25 Degussa (komersial). Proses dilakukan dalam reaktor fotokatalitik berukuran
30 x 15 x 20 cm dengan radiasi sinar UV 50 watt selama 90 menit pada temperatur kamar dan setiap 15 menit
diambil sampel untuk dilakukan analisa BOD5, COD, dan TDS. Variabel percobaan yang digunakan adalah rasio
volume (v/v) lindi/H2O sebesar 1/4; 1/8; 1/12; 1/16 dengan jumlah katalis yang digunakan masing-masing
sebanyak 1 gram. Hasil penelitian pada rasio volume (v/v) lindi/H2O sebesar 1/16 menunjukkan penurunan
BOD5, COD, TDS masing-masing sebesar 45; 90,43; 100 % untuk katalis Fe2O3-TiO2 dan sebesar 80,6; 75; 100
% untuk TiO2 P-25 Degussa. Penelitian juga memberikan gambaran bahwa mineral Ilmenit Bangka Indonesia
berpotensi besar sebagai bahan baku dalam pembuatan katalis Fe2O3-TiO2.

 

Abstract

The current work presents the results of investigation on the decreasing levels of BOD5, COD, TDS of
leachate on the landfill (TPA) Cilowong by using Fe2O3-TiO2 catalyst derived from the extraction process of
Bangka Indonesia ilmenite as well as commercial TiO2 P-25 Degussa catalysts. The measurement was
carried out in a photocatalytic reactor of 30 x 15 x 20 cm equipped with a 50 watt UV radiation. The process
was performed for 90 minutes at room temperature, and the samples were taken every 15 min for BOD,
COD, and TDS analyses. The ratio of leachate to H2O (%v) was varied as 1/4; 1/8; 1/12 and 1/16, with the
amount of catalyst used was 1 gram. The result on ratio of leachate to H2O of 1/16 showed the decrease in
BOD5, COD, TDS with the use of Fe2O3-TiO2 catalysts by 45; 90.43 and 100% for Fe2O3-TiO2 catalysts,
while with the use of Degussa P-25 TiO2 catalysts the decrease in BOD5, COD, TDS reached by 80.6; 75 and
100%, respectively. On the basis of findings, it is shown that Ilmenite Bangka Indonesia has great potential
as a raw material for synthesizing the Fe2O3-TiO2 catalysts.
