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.

Research aimed to identify the characteristics of the owner of the handwriting, so that handwriting can be recognized and able to prevent forgery of handwriting through two methods, namely the inner product and cosine. The increased use of handwriting as a means for authentication and authorization from accessing an account or specific media, it takes a technological advancement in terms of security handwriting. Both method will be compared to the level of accuracy in recognizing the characteristic and the owner of the handwriting. Steps being taken to 100 consists of digitized handwritten documents, pre-processing such as color conversion and thresholding, and gridding stage, feature extraction, and pattern recognition through the inner product and cosine. From the test results which consists of 60 training data (in database) and 40 test data through methods cosine, 9 data misidentified, 10 unknown data, and 21 data has correctly identified the owner of the handwriting, so accuracy is obtained only by 52.5%.While testing with the same data through inner methods, produced 27 recognized correctly managed data, 13 data is not in accordance with the owner's handwriting, so accuracy is obtained from the inner product method amounted to 67.5%. Overall it can be concluded from this study, the use of methods of cosines and inner product in identifying the owner of the handwriting can produce fairly good accuracy, where accuracy inner product value is still higher than the cosine
Anthocyanin (Acn) is one of the secondary metabolites of Clitoria ternatea flower (Ctf) with many health maintenance and therapeutic benefits. Acn acts as anti-inflammation and anti-proliferative of breast cancer cells in vivo. Ct blooms daily for just one day. We carried out this study to analyze the feasibility of Ctf as the acn resource beside the famous blackberry. Its maceration in 70% ethanol divided into two groups according to the temperature of evaporation, which are 40oC and 60oC, respectively. We measured the total acn contents (TAC) with the spectrophotometer at 230-1000 nm wavelength. The average of TAC in each group was 73.15 + 8.66 mg and 46.07+1.54 mg/100 g, respectively. The data showed that anthocyanins better produced at a lower temperature, with less energy consumption. The main peaks in the 1stgroup profile were at 230, 268, 578, and 625 nm, while in the other, they were at 230, 267, 568, and 622 nm. The profiles show considerable absorbance values of their anthocyanins with health benefits such as blackberry. Ctf is a potential source of anthocyanins for our daily food
