Analisa Pengujian Repeatability Timbangan Elektronik dengan Metode Syarat Teknis Timbangan Non Otomatis dan Metode NMI Australia
No full textTesting repeat electronic scales with non-automatic scales technical requirements so far is fairly long if not using a calculator or computer. The aim of this research is to compare the repeatability testing method of electronic scales using methods according to the technical requirements of non-automatic scales and the Australian NMI method, both of which refer to OIML R76 in determining the validity or cancellation of electronic scales repeatability testing. This research method is done through repeat testing on 3 samples of electronic scales, then on each electronic scale 2 test methods are performed. The conclusion is that the electronic scales repeatability testing uses the non-automatic scales technical requirements method and the Australian NMI method has some differences although both refer to OIML R76. These differences include several points, namely the charge used, the method of adding additions, the formula for determining electronic scales, and different test results. The Australian NMI method is deemed to make it easier and more time efficient compared to the non-automatic weighing technical requirements method

Analysis of statistical literacy content in Curriculum 2013 mathematics textbook
Abstract
Statistical literacy was one of the competencies that must be mastered by everyone to face the 4.0 Industrial Revolution era. At the level of primary and secondary education, statistics was studied as a part of the mathematics subject. In this research. We examine the extent to which statistical Literacy contents were supported by Mathematics subjects from the Elementary School (SD) level, Junior High School (SMP) level, to the Senior High School (SMA) level. This research focused on the textbooks used in the learning process. The data were collected by analyzing the contents of the mathematics curriculum document (following the Curriculum 2013 Revision Edition of 2016) as well as mathematics textbooks referring to the Curriculum 2013 Revision Edition of 2016 especially books published by the Ministry of Education and Culture of the Republic of Indonesia. Based on this research, it is known that the majority of statistical literacy competencies have been supported by the Curriculum 2013 mathematics textbook at SD, SMP, and SMA level. Some improvements could still be made to increase the breadth and depth of statistical literacy
Creative thinking ability and cognitive knowledge: Big Five personality
No full textThis research aims at describing the ability and level of student\u27s creative thinking and student\u27s cognitive knowledge. It is qualitative research to search for data and information. Operationally, this research was conducted with some steps namely: (1) giving a set of big five personality test to 215 students to determine their personality type, (2) giving a set of creative thinking test of 215 students to measure the ability and level of their creative thinking, and (3) choosing one student randomly from each student\u27s personality type to be interviewed to search their cognitive knowledge. The results show that every student has a creative thinking ability, but the level of creative thinking varies. The category of student\u27s creative thinking ability based on Big Five Personalities is \u27moderate or high\u27. The level of student\u27s creative thinking based on the big five personality is \u27very creative, creative, quite creative or less creative\u27. The student\u27s cognitive knowledge based on the big five personality is drawing, designing, ascertaining, dividing, reasoning, analogy, imagining, utilizing, solving, understanding, determining, mentioning, and using trial and error
Parallel tests viewed from the arrangement of item numbers and alternative answers
No full textThis research aims to prove that a parallel test can be constructed by randomizing the test item numbers and or alternative answers\u27 order. This study used the experimental method with a post-test only non-equivalent control group design, involving junior high schools students in Yogyakarta City with a sample of 320 students of State Junior High School (SMPN) 5 Yogyakarta and 320 students of SMPN 8 Yogyakarta established using the stratified proportional random sampling technique. The instrument used is a mathematics test in the form of an objective test consisting of a five-question package and each package contains 40 items with four alternatives. The test package is randomized in the item numbers\u27 order from the smallest to the largest and vice versa. The options in each item are also randomized from A to D and vice versa. Each item is analyzed using the Classical Test Theory and Item Response Theory approaches, while data analysis is done using the discrimination index with Kruskal-Wallis test technique to see the differences among the five-question packages. The study reveals that the result of item analysis using the Classical Test Theory and Item Response Theory approaches shows no significant difference in the difficulty index among Package 1 until Package 5. Nevertheless, according to the Classical Test Theory, there is a category shift of the difficulty index of Package 2 until Package 5 when compared to Package 1 - the original package - which is, in general, not a good package, because it contains too easy items
