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.

Curcuma longa (turmeric) extract is known to have good and stable antioxidant properties. Therefore, this study aims to determine the antioxidant activity of the turmeric extract towards the inhibition of trans fatty acids formation in repeatedly heated cooking oil (RCO). This experimental research was conducted through several procedures, including maceration to obtain the turmeric extract, which was subsequently added to the RCO resulting from 1, 5, and 10 frying times. In addition, the extraction of oil absorbed in fried food was also performed, followed by contents analysis of trans fatty acids. The results showed the potential application of turmeric extract as an antioxidant, due to the high IC50 value of 12.38μg/mL, alongside 21.85% free radicals suppressing activity in cooking oils
For athletes who play adventure sports such as baseball, hockey, or in the military, they often use helmets that require high strength. Consequently, helmets are often designed with additional bearing frames. Conventional collisions come from the direct collision of the helmet's shell, transmitting force onto the load-bearing frame of the helmet then shifting force to the head of the helmet. Therefore, the bearing frame structure significantly plays a vital role in human safety. This paper investigates a simulation solution to minimize the impact on the head of a person when the helmet frame is impacted with a rigid object moving at high velocity. The metal frame structure is calculated to provide the best bearing capacity, combined with Foams/Styrofoam material to absorb energy. From that, we propose solutions to improve the structure and select the appropriate materials to minimize the impact on the head of the helmet when the collision occurs. In this study, the authors used finite element analysis (FEA) and performed on ABAQUS software
