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.

The purpose of the research is to produce the item bank to measure polytechnics students’ performance in Mathematics algebra topic. Computerized Adaptive Test, an adaptive mode of testing that has the features to measure the performance of test takers based on their ability level. Computerized Adaptive Test has the ability to precisely target test item difficulty to estimate test-taker ability. However, computerized test can only be realized if item bank that contains sets of questions with different difficulty levels is developed. In order to produce the item bank, this study uses a combination of linking and equating of 36 sets of test related to Mathematics Algebra. All 36 sets of test are administered to a sample of 1,464 students from 4 polytechnics in northern Peninsular Malaysia. The findings of this research show that the item banks are credible and reliable. Using Rasch model and item-response-theory, this research proves that the items can be used for item bank designed for Computerized Adaptive Testing
This paper presents the effect of grinding parameters on surface roughness of workpiece’s surface when dry cylindrical grinding X12M steel using CBN grinding wheel. The factor selected as the criterion for evaluating the grinding process is the surface roughness of the workpiece. The CBN grinding wheel, 1A1-400D-45T-2X-75HSL100N100BI, was used in this study. Three grinding parameters mentioned in this study include feed rate, velocity of workpiece and depth of cut. The experiment was conducted with fifteen experiments according to the Box-Behken matrix. The influence of the each parameter and influence of the interaction between the grinding parameters on surface roughness was also analyzed in this study. This study has also built a regression model on the relationship between surface roughness and the grinding parameters with the correlation coefficient R2 = 0.9805. This is the basis for selecting and controlling the value of the grinding parameters in order to obtain the surface roughness according to specific requirements
