Analysis of Tuberculosis (TB) Case Patterns Using the Hurst Exponent Fractal Dimension Method in North Sumatra

2024-08-01T04:36:10+00:00

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.

The Complexity of Octopus Graph, Friendship Graph, and Snail Graph

2024-08-01T03:57:42+00:00

Graphs are basic structures that represent objects with nodes and relationships between objects with edges. Trees are one of the parts studied in graph theory along with finding the number of spanning trees of a graph such as octopus graph, friendship graph, and snail graph. The complexity of an octopus graph is strongly dependent on the number and length of tentacles, the complexity of a friendship graph is dependent on the number of triangle cycles, and the complexity of a snail graph is dependent on the number of edges and vertices located in the shell-like part of the snail. To calculate the number of spanning trees (τ(G)) of a graph, various calculations can be used, such as the extension of Kirchhoff's formula. The extension of Kirchhoff's formula uses the determinant of the adjacency matrix and degree matrix of the graph complement of a graph. Therefore, this research applies the extension of Kirchhoff's formula to obtain the complexity of octopus graph, friendship graph, and snail graph. From the analysis, it is obtained that for any n≥2, the number of spanning trees of octopus graph and friendship graph are τ(O_n )=1/5 √5 [((3+√5)/2)^n-((3-√5)/2)^n ] and τ(F_n )=3^n and the number of spanning trees of snail graph is τ(SI_n )=2^(n+2)+3n∙2^(n-1) for n≥1.

Culturally Contextualized E-Module Based on Papua: Why Teachers and Students Need It for Teaching Linear Programming Material?

2024-07-31T12:06:27+00:00

The use of e-modules in mathematics learning significantly aids both teachers and students in the teaching and learning process. However, the design of e-modules has not been extensively linked to the cultural context in which students live. Therefore, this study aims to explore and analyze the needs of teachers and students in developing culturally integrated e-modules, particularly those reflecting the culture of Papua, for high school students. The research design employed is phenomenological. Participants included Mathematics teachers for grades X, XI, and XII in Nduga Regency, Papua Highlands, and 64 high school students (42 male and 22 female). Data collected from observations and interviews were qualitatively analyzed using Miles-Huberman Interactive Analysis. Findings revealed that the high schools still use the 2013 curriculum, relying on standard textbooks as teaching materials. These textbooks pose problems for students as they are often uninteresting, use formal language, are difficult to understand due to abstract content, and are not contextualized to students' daily lives. Additionally, the reduction in face-to-face learning hours, due to the school's location in a conflict area, hampers effective teaching and learning processes. Another interesting finding is that high schools in Nduga Regency have not yet utilized technology in learning, despite having internet access. These findings imply the need for teaching materials integrated with technology and local culture to help students understand mathematics concepts and assist teachers in teaching both inside and outside the school.

Breakfast is an activity that has benefits for school children which contributes energy and nutritional needs to support daily activities. Better memory is associated with increased glucose, indicating brain performance, especially those related to memory aspects. Consuming breakfast can improve cognitive learning and academic achievement. If children have good nutritional knowledge, they will determine which foods to consume that are healthy and have high nutrition. The aim of this research is to determine the relationship between breakfast habits and knowledge of nutritional status and learning achievement at SMPN 02 Banjar Agung, Lampung. The method used in this research uses descriptive analytics with a cross sectional approach. This research was conducted from June to July 2022. The number of samples in this research was 120 class VII students at SMPN 02 Banjar Agung who were filtered according to inclusion and exclusion criteria. The data was tested in the semester. This research showed that 100 people (80.0%) had good breakfast habits and 89 people (74.2%) had good learning achievements. Based on the results of the Chi Square test, the relationship between breakfast and knowledge of nutritional status obtained a p value = 0.040 (p < 0.05). The results of the Chi Square test regarding the relationship between breakfast and learning achievement obtained a p value = 0.000 (p < 0.05). It can be concluded that there is a significant relationship between breakfast and children's nutritional status and learning achievement.

Implementation of the PIMCA Learning Model Assisted by HOTS-based LKPD to Improve Critical Thinking Skills on Temperature and Heat Material

2024-08-13T03:15:19+00:00

Critical thinking skills are one of the skills that students must have. This skill can be trained through various scientific disciplines, one of which is physics. If we look at its characteristics, temperature and heat physics material is able to train students critical thinking skills using the knowledge and experience they have. But in reality, students consider temperature and heat material to be difficult and boring. This is due to lack of student involvement and lack of student understanding of temperature and heat material. Therefore, this research aims to determine the improvement of students' critical thinking skills through the use of the PIMCA learning model assisted by HOTS-based LKPD on temperature and heat material. The research method used is quantitative with a one group pretest-posttest design. The research instrument is a critical thinking skills test in the form of an essay. Data analysis of critical thinking skills test results includes normality testing, hypothesis testing, and continues with the n-gain test to obtain in-depth information regarding students critical thinking skills. In general, the research results show that the average critical thinking skills of students is 0.76 in the high category. High levels of critical thinking skills can be seen in the categories of elementary clarification, basic support, inference, and strategy and tactics. Meanwhile, students critical thinking skills in the category of advanced clarification are still in the medium category.
