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.

Surface roughness is an important parameter determining the quality of machine elements, with the desire to reduce surface roughness to increase the quality of the product. This paper uses the experimental design method of Taguchi in combination with genetic algorithm (GAs) to study the optimization of surface roughness of machine elements when external cylindrical grinding 9CrSi steel. The smallest surface roughness achieved is Ra = 0.258261 m when feed rate Sd = 0.3 m/min, the rotation speed of the workpiece nw = 100 rpm, and the depth of cut t = 0.005 mm
This research examines the degradation of lignin by photocatalytic activity from oil palm empty fruit bunches (OPEFB) by the FeTiO3.TiO2/Ti reagent. This reagent was synthesized by the dissemination of the liquid phase by TTIP and Fe (NO3)3 prepared by the sol-gel technique utilizing acetylacetonate, acetic acid, and ethanol. Then, its morphology and structure are characterized via scanning electron microscopy energy dispersive (SEM-EDX) and X-ray diffraction (XRD). The outcomes found that FeTiO3.TiO2/Ti and TiO2/Ti reagent crystals consisted of anatase TiO2 phases. Though, FeTiO3.TiO2/Ti reagent performed well against degradation of lignin under the treatment of visible light with a degradation proportion of 64.26% in 50 minutes. The high photocatalytic activity of this reagent occurs for the least number of Fe ions, producing a duping effect in separating photogeneration holes and electrons
