Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

Garlic (Allium sativum L) is one of the horticultural plants in Indonesia that is used to enhance the taste of food and medicine to cure various diseases. During the heating process, the content of anti-oxidant active substances in garlic will increase along with the heating process, one of the antioxidant compounds in black garlic is polyphenol compounds. The purpose of this research was to obtain the value of water content and pH in the process of produced Black garlic, to obtain the best heating time for Black garlic in terms of the total polyphenol content during the heating process, and to obtain the optimal time for the extraction process of Black garlic the using ultrasonic method on the concentration of total polyphenol content. The results showed that The effect of heating time will affect the water content and pH of Black garlic products with a regression value of R2 = 0.9965 for water content and R2 = 0.9953 for pH. The heating time of Black garlic will increase the total polyphenol content with a regression value of R2 = 0.9758. The results of the hedonic test of the best Black garlic products based on the taste aspect are 85% of respondents and the ease of consumption is 70%, namely on heating for 14 days. The best total polyphenol content in the extraction time variation was 15 minutes with a polyphenol content of 946.87 mg/kg.
TiO2/Ti electrode preparation has been carried out by anodizing, sol-gel and dip coating methods while tellurium coating has been carried out using the dip coating method to obtain Te-TiO2 / Ti electrodes. Photo current response of TiO2 / Ti and Te-TiO2 / Ti tested on photoelectrocatalyst shows that TiO2 / Ti electrodes are active in UV light and Te-TiO2 / Ti is active in visible light. The results of characterization using XRD showed anatase crystals, SEM showed nano tube crystals against Te-TiO2 / Ti electrodes, EDX confirmed Te on Te-TiO2 / Ti electrodes, with a percentage of 2.48%. Measurement of UV-Vis Diffuse Reflectance Spectroscopy (DRS UV-Vis) was done to determine the band gap energy of the prepared TiO2/ Ti and Te-TiO2 / Ti electrodes, LSV shows that the TiO2 / Ti electrode is active in UV irradiation and the Te-TiO2 / Ti electrode is active in Visible light. The results of the UV-Vis spectrophotometer analysis that degraded the reactive blue 160 compound by photolectrocatalyst showed that the TiO2 / Ti electrode was active with UV light irradiation with a degradation rate constant of 0.0289 minutes-1 and active Te-TiO2 / Ti with visible irradiation with a degradation rate constant of 0.0653 min
