Abstract

This study aims to determine the level of creative thinking of MTs Negeri 1 Muara Enim stnudents in solving mathematical problems in the context of suspension bridges. Taking the subject using purposive sampling technique, the subjects of this study were 3 students with high mathematical abilities. Test questions to see creative thinking skills and interview clues are used as research instruments. Data reduction, data presentation, and drawing conclusions are outlined guidelines in analyzing data in this study. The results showed that the three subjects in this study had been able to demonstrate and present their creative thinking abilities with diverse levels of creative thinking. Based on the results of the answers to the 2 essay questions given, MSE subjects were able to meet the existence of fluency and novelty indicators which showed that they were at the level of creative thinking ability 3 (creative) while CR and RA subjects were only able to meet the novelty indicators that were at the level of creative thinking ability level 2 (quite creative).

Abstract

Over the past century, there has been a dramatic increase in worldwide research.  However, these rapid increases are also arising problems or difficulties faced by the university students. Therefore, this research was carried out to reveal the types of those difficulties faced by students of STKIP Pacitan PGRI in solving the two-factor experiment tests in the design of experiment subject and the factors which cause these difficulties.  The researcher opted the qualitative descriptive design to the qualified research findings. Moreover, the samples, 15 students, were randomly taken from the total population or 93 students who attended the lectures. The technique of collecting the data employed both written test and interview of the researched subject. Based on the research findings, the students were difficult in determining the source of variance (SV), the degrees of freedom (df), the Expected Mean Square (EMS), the F value. Briefly speaking, the students were difficult in the process of calculating. While, the factors that caused the difficulties were in distinguishing the state of R, drawing a conclusion from all these factors, determining the number of r (replicate), determining the removed part from EMS, being careless in equalizing the line of numerator and denominator candidate, being unable to develop formulas, and careless in the calculation. Keywords: kesulitan, rancangan, faktorial

Abstract

AbsrtactMathematics is one of the compulsory subjects taught at all levels of education. a model is neededto support students' needs to improve students' understanding of concepts. The CORE learningmodel with the Student facilitator and explaining strategy is very good in improving students'understanding of mathematical concepts. The purpose of this study was to determine theeffectiveness of the CORE model with a student facilitator and explaining strategy on students'understanding of mathematical concepts. This study uses a quantitative method with a quasiexperimental approach and a non-equivalent control group design. the author conducted a test ofvalidity, normality, homogeneity and reliability of the test to determine the correctness andsuitability of the instrument used. From the calculation results, the results of the test have a validvalue and have a normal distribution. For the homogeneity and reliability test, all items werehomogeneous. The calculation using the Crombach alpha reliability test was obtained for all itemsmore than 0.05, so all items on the test were appropriate or reliable. It is known that the results ofthe t-test analysis in the experimental class have an average value (mean) of 63.7 post-test andpre-test of 47.5, the increase in the average result is known to be 16.2 for all test results. Inaddition, from the results of the percentage of the effectiveness of the model category, the result isa value of 63.75. So, from these results the category of effectiveness of the learning model isincluded in the category of quite effective.

Abstract

Abstract Mathematics is a subject that is quite difficult for students. Many students feel anxious when faced with math problems. The purpose of this study was to determine the level of math anxiety possessed by students based on their learning outcomes. This research is a descriptive qualitative research with 62 junior high school students representing each category of anxiety as subjects. Data collection techniques in this study include observation, questionnaires, interviews, and tests. The results of the study show that the math anxiety experienced by students in solving flat-sided geometrical problems consists of 4 levels of anxiety, namely the category of no anxiety as many as 8 students or 13%, the category of mild anxiety as many as 34 students or 55%, the category of moderate anxiety as many as 18 students or 29%, severe anxiety category as many as 2 students or 3%. Overall, students’ mathematical anxiety in solving problems on solid shapes topi was in low category with the average score of test result is 38,18 which is in opor category.   Keywords: Learning Outcome, Mathematics Anxiety

Abstract

An extension of the metric space in which the distance of the same point is not always zero is called a partial metric space. Orthogonality is the relation of two perpendicular lines at one point of intersection forming a right angle. There are several ways to define orthogonality, including Pythagorean Orthogonality, Isosceles Orthogonality, and Birkhoff-James Orthogonality. The purpose of this research is to study the consistency of the definition of orthogonality in the metric space to the partial metric space. Based on these results, it can be concluded that the partial metric space can be obtained by linear induction from a metric space. Then, in developing the definition of orthogonality to the partial metric space, it can be concluded that the qualified orthogonality is the I-orthogonality and the BJ-orthogonality, while the P-orthogonality does not qualify the consistency of the definition of orthogonality in the partial metric space. Kata Kunci: Orthogonality, Consistency, and Partial metric space

Abstract

Abstract This study aims to improve science learning outcomes for class VII A students of SMPN 3 Kasihan through the picture and picture cooperative learning model. This is because students are less active in teaching and learning activities as well as low attention to learning material. This type of research is Classroom Action Research (PTK) with the research subject of class VII A students of SMPN 3 Kasihan for the 2018/2019 academic year, a total of 32 students. The implementation of the action was carried out in 2 cycles, each cycle consisting of 2 meetings. The instruments used are observation, documentation, and test. Observation is used to observe during the teaching and learning process, documentation to collect data and student test results, as well as test methods that are carried out at the end of each cycle which are useful for knowing the increase in student learning outcomes. The data analysis technique is in the form of descriptive qualitative. This study showed an increase in student learning outcomes KI 3 (knowledge) cycle I obtained a completeness level of 37.50%, cycle 2 increased to 100%, which means there was a significant increase of 62.50%. Whereas in KI 4 (skills) in cycle 1 the level of completeness reached 59.38% while in cycle 2 it was 90.62% which means there was a significant increase of 31.24%.   Keywords: Learning Outcomes, Picture and Picture.

Abstract

Tuberculosis is a disease caused by the Mycobacterium tuberculosis. Multi-Drug Resistant Tuberculosis (MDR-TB) is the term used to describe Mycobacterium tuberculosis that is resistant to one or more Anti-TB drugs. This study aims to determine the factors that affect the number of patients recovering from MDR-TB, by modeling the number of MDR-TB cured patients using Multivariate Adaptive Generalized Poisson Regression Spline (MAGPRS) method. The predictor variables are the average age (X1), percentage of patients who fail category 2 treatment (X2), percentage of patients who fail category 1 treatment (X3), percentage of patients relapsed (X4), percentage of patients neglecting treatment (X5), and percentage history of close contact with other patients (X6). A combination of BF (Basis function), MI (Maximum interaction), and MO (Minimum observation), the BF value is two to four times of predictor variables, MI has value of 1,2, and 3, and MO has value of0,1,2, and 3. From the result, the best model was obtained from the combination of BF=24, MI=3, and MO=1, with GCV values of 0,3504 and R2 of 88,3%, and there are 14 BF that affect the response variable . The most influential predictors variables in a row, are X6, X3, X5, and X2.  Keywords: Poisson, basis function, GCV
