“…However, the reactivity of TiO2 is only active in ultraviolet (UV) light which affects its performance so that the modification of TiO2 material is needed to improve the performance under visible light which expected to be able to utilize sunlight as abundance source in nature [12][13][14].…”

Preparation of ilmenite (FeTiO3) composite for antimicrobial under UV-visible lights irradiation was carried out to appropriate as a new antimicrobial material. The preparation of FeTiO3 by using sol-gel method was conducted by the titanium tetra-isopropoxide (TTIP) as precursor titania and added Fe(NO3)3 as Fe source. Subsequently, the antimicrobial test (Escherichia coli, Staphylococcus aureus and Candida albicans) was carried out under photocatalysis system. The FeTiO3 was formed on 2θ of 20°, 24°, 36°, 48°, 53° and 62° having crystal size 53.75 nm. Scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDX) was investigated that the particle sized was under 100 nm and Fe element peak was on 6.398 keV. The antimicrobial test showedthat the efficiency of 15 % FeTiO3 was active under visible light irradiation to inhibit of E. coli, S. aureus and C. albicans with diameter zone were 18.778, 19.889 and 20.22 mm, respectively.

This study aims to obtain phenolic lignin derived compounds through the lignin degradation of oil palm empty fruit bunches (OPEFB) using TiO 2 photocatalyst and its antifungal activity against Fusarium oxysporum. The lignin degradation of OPEFB begins with the extraction and isolation stage using the soxhletation method with the presence of sodium hydroxide as a catalyst. The success of this stage is indicated by Gas Chromatography (GC) measurement of 4-vinylguaiacol and Fourier Transform Infra Red (FTIR) spectroscopy measurement that indicated the appearance of seven specific peak of lignin occurring at wave numbers 3421 cm -1 , 2929 cm -1 , 1596 cm -1 , 1508 cm -1 , 1462 cm -1 , 1041 cm -1 , and 875 cm -1 . This result is supported by the appearance of specific peaks of guaiacyl and syringyl groups at wave numbers 1328 cm -1 and 1220 cm -1 . Based on the variation of the degradation time, the lignin degradation of OPEFB with a degradation time of 15 min. showed optimum results in the production of lignin derived compounds. In addition, it also provides a strong inhibitory response to the growth of Fusarium oxysporum with a clear zone diameter 2.39 cm.

“…Titanium dioxide (TiO2) is one of the semiconductor oxides that has been studied extensively as a photocatalyst since the effect of light sensitization was found by Fujishima and Honda in 1972 [12]. TiO2 is mostly used as photocatalyst because it has the characteristics of optic and electronic, very photoreactive, non-poisonous, having long-term chemical stability and relatively low-cost [13,14].…”

The degradation of methylene blue dye has been conducted by Ag@S-TiO2/Ti electrode to increase the plasmon effect on visible light. The addition of silver metal was applied using electrodeposition method. While the S-TiO2 was prepared by sol-gel and immobilization on TiO2/Ti electrode. The results showed that the X-ray diffraction pattern of TiO2/Ti electrode was anatase crystal. Fourier transform infrared analysis in the wavenumber of 1120 and 413 cm -1 indicated the existence of S-O and Ti-O bonds. Supporting by scanning electron microscope and energy dispersive X-ray (SEM-EDX) on Ag@S-TiO2/Ti electrode, the existence of Ag, Ti and S were 2.9, 4.5 and 2.3 KeV, respectively. The plasmon effect identity was active on visible light irradiation confirmed by the photoelectrocatalyst system using linear sweep voltammetry (LSV). Based on the UV-visible spectrophotometer measurement the efficiency of methylene blue degradation was 81.15 % on 0.5 ppm.
