Abstract

Difficulty in learning mathematics is a disorder in students that can lead to a lack of student success in learning. Difficulties can be in the form of difficulties in understanding concepts, principles and problem solving. The purpose of this study was to determine the form of students' learning difficulties in mathematics. This research method uses a qualitative descriptive approach. The subjects in this study were selected by purposive sampling and as research subjects were students of class XI MIPA 3 SMA Negeri 2 Gunung Talang. The research instruments were tests and interviews. The data analysis technique uses the Miles and Huberman technique, namely, data reduction, data presentation, and drawing conclusions. The results showed that students had difficulty applying the concept to the inability indicator in inferring information from a given concept. Difficulty in applying principles to indicators relating concepts between materials, difficulties in using formulas and difficulties in mastering algorithms. Difficulty in solving problems, on indicators of students' inability to perform calculations.

Abstract

The role of mathematics needs serious attention, considering its benefits in everyday life. Mathematics lessons are provided starting from elementary school to tertiary institutions in order to equip students to have the ability to think logically, critically, and creatively. The low ability to understand students' mathematical concepts is due to the fact that previously, students carried out online learning, so the teaching carried out was not adequate, and many students did not do the assignments given, resulting in students not understanding mathematical concepts correctly. The purpose of this study was to describe the ability to understand mathematical concepts of class VIII.1 students of SMP Negeri 2 Tanjung Raya. The subjects of this research were class VIII.1 students of SMP Negeri 2 Tanjung Raya. The research method used is a descriptive method with a qualitative approach. The sampling technique used purposive sampling. Instruments are used to collect data in the form of tests of ability to understand the concept, interviews, and documentation. The test results were analyzed based on indicators of understanding the concept. The results of the research on academic ability related to the ability to understand concepts are high, medium, and low from the test results.

Abstract

Padang City Market is one of the shopping centres in Padang City, which is located in the West Padang District. The shopping centre presents a place for people to buy kitchen supplies or basic daily needs. This makes the area quite attractive for community travel. This research was conducted on 400 respondents who visited Padang City Market. In this study, the choice of mode is represented by the Y variable and is categorized into private vehicles, public transportation, rental vehicles, walking, and others. The travel time variable represents X1. The variable price of goods represents X2. This study aims to assess the level of correlation between the choice of mode (Y) on the variable travel time (X1) and the variable price of goods (X2). Furthermore, the mode selection (Y) was modeled based on the variables X1 and X2 using linear regression analysis with SPSS tools. The results of the analysis show a strong relationship between the Y variable and the X1 and X2 variables. The best linear regression model produced is Y = 0,010 + 0,76X1 + 0,029X2 with a value of R = 0,437. This means that the closer the travel time is and the lower the price of goods, the more the intensity of motorcycle mode selection to Pasar Raya Padang increases.

Abstract

Kemampuan pemahaman konsep matematis merupakan kemampunan dasar yang harus dikuasai siswa. Penelitian ini menggunakan pendekatan korelasional yang bertujuan untuk melihat hubungan pemahaman konsep matematis dengan kemandirian belajar siswa pada kelas VIII di salah satu SMP di Lubuk Basung. Teknik pengambilan sampel menggunakan simple random sampling. Instrumen yang digunakan berupa tes pemahaman konsep matematis dan angket kemandirian belajar siswa. Teknik analisis data yang digunakan adalah analisis regresi linier sederhana. Berdasarkan hasil penelitian, dapat disimpulkan bahwa terdapat hubungan kemandirian belajar siswa dengan kemampuan pemahaman konsep matematis dengan arah hubungan positif sebesar 0,845, artinya semakin baik kemandirian belajar maka akan baik juga kemampuan pemahaman konsep matematis. The ability to understand mathematical concepts is a basic ability that must be mastered by students. This study uses a correlational approach that aims to see the relationship between understanding mathematical concepts and student learning independence in class VIII one of the SMP in Lubuk Basung. The sampling technique uses simple random sampling. The instruments used were tests of understanding mathematical concepts and questionnaires for student learning independence. The data analysis technique used is simple linear regression analysis. Based on the results of the study, it can be concluded that there is a relationship between student learning independence and the ability to understand mathematical concepts with a positive relationship direction of 0.845, meaning that the better the independent learning, the better the ability to understand mathematical concepts.

Abstract

This study aims to analyze the correlation between temperature, humidity, and Rainfall at the Geophysics Station of Padang Panjang from 2020 to 2023. Monthly data from the Meteorology, Climatology, and Geophysics Agency (BMKG) was used to evaluate the relationship between these meteorological variables. Statistical analysis, including correlation and multiple linear regression, was conducted using SPSS version 22. The results show a significant negative correlation between Rainfall and temperature, indicating that temperature tends to decrease as rainfall increases. In contrast, a positive correlation between Rainfall and humidity suggests that higher humidity levels are associated with increased Rainfall. However, the regression analysis reveals that temperature and moisture explain only 16.76% of the variation in Rainfall, indicating the potential influence of other factors not included in the model.
