Dalam matematika, dimensi ruang vektor V dan W adalah jumlah vektor basis V dan W. Himpunan semua transformasi linier dari V ke W dengan operasi penjumlahan dan operasi perkalian skalar menciptakan ruang vektor. Ruang vektor dari transformasi linier biasanya dilambangkan dengan Ł (V,W). Ł (V,W) ={T ∶V→W |Transformasi linier T}. Tujuan dari penelitian ini adalah untuk menentukan dimensi vektor ruang Ł (V,W) melalui pemetaan isomorfisme. Peneliti melakukan studi pustaka untuk menentukan dimensi vektor ruang Ł (V,W). Penelitian menunjukkan bahwa ada pemetaan isomorfisme dari Ł (V,W) ke M_mxn Dapat disimpulkan bahwa Ł (V,W) = {T: V →W|Transformasi linier T} dengan vektor ruang V yang memiliki n dimention dan vektor spce W yang memiliki m dimention adalah vektor ruang dimensi terbatas. Dim (Ł (V,W)) dapat ditentukan dengan menunjukkan matriks standar M_mxn merupakan basis, sehingga dim(M_mxn) = mn. Jika Ł (V,W) ≅ M_mxn maka Dim (Ł (V,W))= dim (M_mxn)Kata kunci: Pemetaan isomorfisme, Dimensi, Vektor ruang, Transformasi linier.

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 of 0,1,2, 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.

Mathematical literacy ability is the ability to understand and to use mathematics in various contexts to solve problems and explain how mathematics can be applied in everyday life. The aim of this study was to analyze students' mathematical literacy abilities in the material for sequences and series using problem based learning (PBL). The sample of this research was class XI SMA as many as 36 students and the subject was determined using purposive sampling. Tests, interviews, and documentation were used as data collection techniques. The research instrument was in the form of a mathematical literacy ability test on sequences and series material as well as interview guidelines that had been validated thereforehe instrument being suitable for use. The results of the study showed that the application of PBL to the matter of sequences and series was able to achieve students' mathematical literacy skills. Students can solve problems systematically and correctly even though there are operations such as multiplication or addition of numbers or variables an error occurs and students from both high and low categories do not write conclusions at the end of the problem. From the ability to choose a strategy students are able to identify the information contained in the question, but not yet fully students can decide on a strategy and apply facts, operations and structures in finding solutions related to story problems on sequences and series material.

Students can solve problems systematically and correctly even though there are operations such as multiplication or addition of numbers or variables an error occurs and students from both high and low categories do not write conclusions at the end of the problem. From the ability to choose a strategy students are able to identify the information contained in the question, but not yet fully students can decide on a strategy and apply facts, operations and structures in finding solutions related to story problems on sequences and series material.","PeriodicalId":31699,"journal":{"name":"JMPM Jurnal Matematika dan Pendidikan Matematika","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75642441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Algebraic reasoning skills are important for students to master, with algebraic reasoning students are able to solve everyday problems in algebraic form. Gender is one of the factors that differentiates students' reasoning abilities in solving math problems. This study aims to describe algebraic reasoning in terms of gender differences. This type of research is qualitative with research subjects of four students taken from 31 students, Middle School class VIII by selecting two female students and two male students based on the average score level of each gender in solving System of linear equations of two variables questions based on indicator of algebraic reasoning ability. Data collection techniques in this study were tests, interviews and documentation. The results of this study indicate that the algebraic reasoning of female subjects is higher than that of male subjects. Some of the factors for the low algebraic reasoning of the subject include: the subject is not careful and forgets the formulas that have been taught.
