Published: March 2020

Abstract
The strong competition allows medical schools to be highly selective in their admissions, with the aim of selecting only those students who are most likely to complete their medical education and presumably become good doctors; it also minimizes the number of poor performers or ‘strugglers’, who were reported in one study to account for academic. The validity of an admission criterion is defined as the degree to which it predicts an applicant’s performance during and after his or her undergraduate medical training, and reliability is defined as the reproducibility of the results obtained when a measurement is repeated on the same study sample. Several studies also show that several non-cognitive factors have a significant influence on academic success at university, additional to the influence of prior academic attainment. The purpose of this research is to assess the correlation between the selection tools and medical student’s academic performance through their Grade Points Average (GPA) over a four-year period. Pre-admission data were matched from students who entered Bandung Islamic University, Faculty of Medicine at the year 2012 – 2016 with their GPA. A cross-sectional study was conducted in 74 selected students who had completed the specific admission test. The variables examined were high school grades, Multiple Mini Interview (MMI), Minnesota Multiphasic Personality Inventory (MMPI) test and a total of admission test score. The statistical was used SPSS and Spearman correlation test analysis. The result shows there were significant correlation and a weak relationship between MMI with 1st year GPA, 2nd year GPA, and 3rd year GPA. There was also a significant correlation and a moderate relationship between the total of admission test score with 2nd year GPA and 3rd year GPA. The conclusion is MMI was found to be steady predictor of Grade Point Average (GPA) yet the predictability of academic success is weak and increase for the early years and drops towards the end of the medical under graduated program. Total of admission test score was weak predictor for academic performance especially in the second and third year medical students.

Abstract
The reinforcement of reinforced concrete always needs a connector. In order to reduce the overlapping length, the long nuts are used as steel bar connector. The tensile experimental test was obtained to find out the value of yield stress, ultimate tensile strength, elongation and ductility which can be achieved by steel bar long nut connection. The test was using UTM machine instrument which connected to the computer, thus stress-strain curve is obtained. The curve shows the values of elastic, plastic, strain hardening until ultimate tensile strength region, value of yield stress Fy, and ultimate tensile strength Fu. The result of tensile tests how’s that the yield stress value of steel bar with long nut connection has the same value with the steel bar without connection. The steel bars with long nut connection can achieve yield stress about 330 MPa, ultimate tensile strength about 340 MPa and strain value about 5%-6%, it is lower than the steel bars without connection. It indicates that long nut can be used as a connector tool in overlapping steel bar connection.

Abstract
Metacognition has an important role in solving mathematical problems. Metacognition in this study consisted of two components, namely metacognitive knowledge (declarative knowledge, procedural knowledge, conditional knowledge) and metacognitive regulation (planning, monitoring, and evaluation). Through the use of metacognition, students can find out what strategies are used and the difficulties that occur when learning and solving mathematical problems. The purpose of this study was to understand whether or not there were differences in metacognition of male and female students in solving mathematical problems. This study was quantitative research. The study was conducted in 87 students consisting of 55 male students and 32 female students from three junior high schools in Surakarta. The instruments used in this study were questionnaires and essay test. The data analysis technique used is the multivariate F-test. The result of this study is that there are differences in metacognition of male and female students in solving mathematical problems. The difference lies in the components of the metacognitive regulation, namely planning, monitoring, and evaluation.

Authors: Azizi H , Herman T 
Published: March 2020

Abstract
This study aims to determine the mathematical critical thinking and communication skills of high school students in trigonometry materials. This research uses descriptive qualitative approach. Subjects were randomly selected from 10th grade as many as five students. The instrument used was a test of critical thinking skills, communication, and non-tests in the form of an attitude scale questionnaire of 16 statements. The results showed that students had critical thinking skills and communication in the low category. Students are not able to complete trigonometry questions completely. This is because students are poorly trained in solving trigonometric problems with non-routine questions. Based on the findings, it can be concluded that: (1) mathematical critical thinking skills of five students of class X on trigonometry material are still relatively low. (2) Mathematical communication skills of five students of class X on trigonometry are still relatively low. (3) There is a relationship between critical thinking skills and mathematical communication of students. (4) And students’ attitudes toward mathematics learning, tests of mathematical critical thinking, and communication skills on trigonometric material are good. So the critical thinking skills and mathematical communication of five students in trigonometry material are still lacking because students have difficulty in modeling trigonometry problems, and stuck with modification questions because many students are not able to complete the answers to the questions given.

Authors: Iskak K B , Kusmayati T A , Fitriana L 
Published: March 2020

Abstract
Conceptual thought is the basic thought in mathematics learning. Process of learning mathematics involves a representation interpretation from a representation form to others. The aim of this research was to analysis the representation process from picture form to mathematics equation. Moreover, this research was descriptive qualitative research. The data were gotten by using test and interview towards 34 students with heterogeneous ability in Surakarta. There were 4 stages in this research, they were unpacking the source, preliminary coordination, constructing the target and determining equivalency. This process involved some other representations such as symbol, schema, verbal, and numeric. Furthermore, the research result showed that the students still had not been able to do the representation process from picture form to equation well. Interpretation process started from picture to equation through other representation mediators like symbols, words and so on. Every student had various ways to do his or her representation. The problem about students’ low mathematics representation could be finished by using a learning medium-based RME. Besides, the suggestions for further research is to do deeper research related to students’ characteristics and to do the opposite research that is an analysis of the presentation process from the equation to picture form.
