Abstract

Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis. This bacteria is commonly known as Acid Resistant Bacilli (BTA). The Hurst Exponent Fractal Dimension method was used in this work to identify the properties of time series data and fractal patterns in tuberculosis (TB) patients. The Hurst exponent method is calculated by the smallest prime factor that divides the data (pi). This fractal dimension's value is calculated using the Hurst exponent value. Time series data is classified into three groups depending on computation results: random, anti-persistence, and persistence. In the study, three data ranges (n) were obtained from the observed data, namely tuberculosis (TB) patients from July to December 2023 (174, 87, and 29). The value of the Hurst exponent obtained was 0,475 (0<H<0,5) and the value of the fractal dimension obtained was 1,525 (1,5<H<2). Based at the Hurst exponent value and fractal dimension fee, it indicates that the records is anti-persistence. Anti-persistence means that the time series data of cases of tuberculosis (TB) patients which if the data increases at one time, it tends to decrease at the next time and if the data decreases at one time, it tends to increase at the next time.

Abstract

Vector is one of the most important subjects in mathematics, but many students face difficulties in learning vector. To find out the cause, this study is conducted to find the differences and similarities in learning opportunities presented in the vector tasks from Indonesian and Singaporean mathematics textbooks. Therefore, vector tasks from the two books are compared with the aspects of representations, contextuality, and response types. Firstly, this study finds out that the chosen Indonesian textbook provides fewer learning opportunities than the chosen Singaporean textbook in terms of vector tasks. Secondly, this study also finds out that the Indonesian textbook tends to present tasks in visual representation, while the Singaporean textbook tends to present tasks in pure mathematics form. Thirdly, this study also finds out that Indonesian textbook usually uses applicative tasks that correlate with real-life situations, while the Singaporean textbook does the otherwise. Lastly, this study also finds out that both textbooks mostly use close-ended tasks.

Abstract

Educational statistics is a crucial course that students of Islamic Education Management must master. However, students whose majors are not directly related to mathematics often face difficulties in learning educational statistics. Therefore, it is necessary to develop a learning model that can improve students' understanding and is applicable to practical courses such as educational statistics. One promising alternative is the Project-Based Learning (PjBL) model. This study was conducted at IAIN Takengon Aceh and involved 23 fourth-semester Islamic Education Management students in the 2023/2024 academic year. The research data were collected in the form of video recordings, photos, and final project reports. The data were analyzed using qualitative techniques and presented through narrative description. The results showed that the PjBL model is effective in promoting an understanding of descriptive statistics, fostering collaboration, and providing opportunities for students to develop problem-solving skills

Abstract

Most students consider mathematics difficult, because it is abstract. To respond to this, teachers can use ethnomathematics in learning mathematics so that mathematics is easy to understand. One of the ethnomathematics objects that can be used is market snacks. Market snacks are traditional foods that are often sold in crowded places such as markets. This study aims to analyze the geometrical concepts that exist in various forms of market snacks in Kudus. This research uses a type of qualitative research with an ethnographic approach. Data collection used semi-structural interviews with 3 market snack sellers, literature studies, and documentation. The results of the study found that there are geometric concepts in market snacks. Triangular, rectangular, and circular shapes are found, while for spatial shapes, rectangular pyramids, blocks, spheres, triangular prisms, and tubes are found. The research results can be used as an alternative source of learning mathematics, especially in geometry material.
