Abstract

This study aims to determine the types of student’s difficulties in solving the mathematical problem material of comparison evaluated from the ability level of students class VII of SMPN 1 Maluk in academic year 2020/2021. The type of research is descriptive quantitative research. The population of this study was students of class VII SMPN 1 Maluk. In determining the sample, the proportionate stratified random sampling technique was used. The sample in this study were 20 students and were taken randomly. The data collection techniques used were test and interview. The results obtained from the research that for high ability students in question number 1 they have difficulty in calculating of 38.88%, difficulty in transferring knowledge of 16.66%, difficulty in mathematical language of 50%, and difficulty in visual perception of 16. ,66%. In question number 2, high ability students have difficulty in calculating of 55.12%, difficulty in transferring knowledge of 52.77%, difficulty in mathematical language of 33.33%, and difficulty in visual perception of 83.33%. For medium ability students in question number 1 they have difficulty in calculating of 59.52%, difficulty in transferring knowledge of 57.14%, difficulty in mathematical language of 71.42%, and difficulty in visual perception of 28.57%. In question number 2, students with medium ability have difficulty in calculating by 71.42%, difficulty in transferring knowledge of 71.42%, difficulty in mathematical language of 85.71%, and difficulty in visual perception of 100%. For students with low ability in question number 1 they have difficulty in calculating of 73.80%, difficulty in transferring knowledge of 85.71%, difficulty in mathematical language of 85.71%, and difficulty in visual perception of 100%. In question number 2, low ability students have difficulty in medium ability of 100%, difficulty in transferring knowledge of 100%, difficulty in mathematical language of 100%, and difficulty in visual perception of 100%.

Abstract

This study aims to analyze mathematical literacy skills in solving PISA mathematics questions based on the level of mathematical literacy skills among students at SMPN 13 Mataram in the 2024/2025 academic year. This is a descriptive qualitative study involving 52 students from classes IX A and IX B, with 8 students selected as subjects. The research instruments used were a mathematics literacy test adapted from PISA and interview guidelines. Data were analyzed based on mathematics literacy process indicators (formulate, employ, interpret). The results showed that out of the 6 levels of mathematical literacy, no students reached levels 5 and 6. At level 1, students could formulate explicit information and solve problems using simple algorithms, at level 2, they could identify implicit information and select basic strategies to solve problems; at level 3, they could process complex explicit information containing distractors and develop sequential strategies for decision-making, while Level 4 can formulate explicit information in everyday contexts and apply strategies to complex concrete situations. Students at Levels 1-4 also have the ability to interpret and draw conclusions based on the context of the problem.

Abstract

The problem of scheduling of teaching and learning at SMKN 5 Mataram was ainteresting problem. On the problem, there were the teachers who teach the same subject at the same time in several different classes. The problem will be solving by the graph coloring concept. Base on the data of scheduling, we obtain the adjecency matrix with size 195 × 195. We use the Welch-Powell algorithm to get the number of coloring graph. By the implentation VBA Macro Excel programming of the algorthm, we obtain the upper bound the number coloring is 5. So, by the upper bound we can design a scheduling without the problen which the teacher who teach the same subject at the same time in several different classes.
