Abstract

Abstrak Telah disintesis komposit TiO2-bentonit untuk penurunan BOD dan COD. Penelitian ini bertujuan untuk mengetahui proses pembentukan komposit TiO2-Bentonit serta mengetahui katalis terbaik dalam proses fotodegradasi air embung. Penelitian diawali dengan preparasi TiO2-Bentonit. Hasil pembentukan komposit dikarakterisasi dengan menggunakan X-Ray Diffraction (XRD), Fourier Transform Infrared (FTIR) dan Scanning Electron Microscope (SEM). Katalis yang diuji adalah TiO2, bentonit, TiO2-bentonit yang diaplikasikan ke air embung dengan waktu penyinaran selama 30 menit.Terbentuknya komposit TiO2-Bentonit ditunjukkan dengan refleksi TiO2 pada 2 25. Hasil analisis menggunakan FTIR yakni Ti-O antara range 400-700 cm -1 dalam hal ini ditunjukkan dalam peak 478.35 dan 594.08. Puncak serapan-serapan utama pada bentonit beradi di bilangan gelombang 3626.17 cm-1, 3448.72 cm-1 dan 1635.64 cm-1. Spektra TiO2-Bentonit tidak menunjukkan adanya pergeseran serapan pada bilangan gelombang 3448.72 cm-1 yang belum  menunjukkan ikatan O-H yang semakin lemah karena adanya TiO2 di dalam antar lapis bentonit.Penurunan nilai BOD dan COD terbesar diperoleh dengan menggunakan TiO2-Bentonit yakni untuk BOD 18.40 ppm dan COD 10.05ppm. Kemampuan komposit TiO2-Bentonit lebih besar dibandingkan katalis TiO2 dan bentonit.   Kata kunci: air embung, fotodegradasi, TiO2-bentonit Abstract   Have done synthesized composite TiO2-bentonite to decrease BOD and COD. This study aims to determine the process of form he composite TiO2-bentonite and determine the best catalyst in the process of photodegradation water reservoir. The study begins with the preparation of TiO2-bentonite. Results composite formation characterized using X-Ray Diffraction (XRD), Fourier Transform Infrared (FTIR) and Scanning Electron Microscopy (SEM). The catalyst is tested TiO2, bentonite, TiO2-bentonite which is applied to the water reservoir with the exposure time for 30 menit.Terbentuknya composite TiO2-bentonite indicated by TiO2 reflection on the 2θ ≥ 25. FTIR analysis results using the Ti-O between the range 400-700 cm-1 in this case is shown in peak 478.35 and 594.08. The main absorption peak-absorption on bentonite beradi at wavenumber 3626.17 cm-1, 3448.72 and 1635.64 cm-1. TiO2-bentonite spectra did not indicate any shift in absorption at wavenumber 3448.72 cm-1 which has not shown the OH bond is weakened by the existence of TiO2 in between layers of bentonite. Impairment The BOD and COD obtained using the TiO2-bentonite for BOD 18.40 ppm and 10.05 ppm COD. TiO2-bentonite composite capability greater than TiO2 catalyst and bentonite.   Keyword: air embung, photodegradation, TiO2-bentonite DOI: http://dx.doi.org/10.15408/jkv.v0i0.3620

Abstract

The ability of inorganic antibacterial agents like metal oxides and nanoscale inorganic materials to inhibit bacterial growth rates has yet to receive much research attention. In this study, CaCO3-ZnO/Y-zeolite nanocomposites were created utilizing coprecipitation and impregnation techniques with Ca(CH3COO)2, Zn(CH3COO)2 2H2O, Y-zeolite precursors. Physical and chemical characteristics of nanocomposites have been investigated using XRD, FTIR, and SEM-EDX characterizations. The agar-well diffusion method tested the substance for antibacterial activity against gram-positive and gram-negative bacteria. Nanocomposites have a crystal size range of 35.46-36.53 nm and a crystallinity of 35-37 %, according to the results of XRD analysis. The carbonate groups are visible in FTIR data at wave numbers 1433, 875, and 712 cm-1. The Zn-O absorption band was verified at wave numbers 600-400 cm-1. The Y-zeolite absorption bands at wave numbers 1012-997 cm-1 and 745-746 cm-1 were confirmed. The particle morphology is cube-shaped with irregular sizes. The EDX result showed that the composition consists of 35.92 % calcium, 1.68 % zinc, 44.81 % oxygen, and 13.79 % carbon as elements. With the addition of 2.5 % Y-zeolite, the antibacterial activity of nanocomposites showed the best results, with an inhibition zone diameter of 7.62 mm against Escherichia coli and 6.56 mm against Staphylococcus aureus bacteria.
