Abstract

Hepatitis B disease is an inflammatory liver disease caused by the hepatitis B virus and can cause liver cirrhosis, cancer, and liver failure. This study discusses the optimal control mathematical model of the dynamics of the spread of hepatitis B. This model consists of six population compartments, namely susceptible to infection with hepatitis B or  Susceptible, Exposed,  infected with acute hepatitis B or Acute Infected , infected with chronic hepatitis B or Chronic Infected, suffering from liver cirrhosis or Liver Cirrhotic, and infected who are recovering or Removed. The system is solved by using Pontryagin's minimum principle and numerically by the forward-backward sweep method. Numerical simulation of the optimal control  shows that with vaccination , campaign on hepatitis B, and treatment, the spread of hepatitis B can be eradicated more quickly. The implementation large amounts of vaccination, campaign on hepatitis B, and treatment  need to be carried out from the start and the proportion can be reduced until a certain time is no longer necessary. The use of controls in the form of vaccinations, campaigns on hepatitis B, and treatment  needs to be carried out for a longer time to prevent the spread of hepatitis B infection.

Abstract

Let G be a simple graph of n order. An edge labeling such that the weights of all vertex are different and elements of the set modulo n, are called a modular irregular labeling. The modular irregularity strength of G is a minimum positive integer k such that G have a modular irregular labeling. If the modular irregularity strength is none, then we called the modular irregularity strength of G is infinity. In this article, we determine the modular irregularity strength of complete graphs.

Abstract

Learning and teaching materials are two things that complement each other. Learning will work if equipped with teaching materials such as textbooks and LKM. The learning process must be able to increase the independence and creativity of students so that their skills are more focused and produce output that is ready to face challenges in the 21st century. One of the alternative 21st-century learning methods that is appropriate to use is the blended learning method . The implementation of the blended learning method will work effectively if it is equipped with teaching materials such as textbooks and LKM as reference materials for students in learning. Therefore, in this study developed STAD type cooperative teaching materials with the blended learning method . The method used in this research is Nieveen's (1999) development method which includes the initial investigation stage, the prototype stage, and the assessment stage. The results of the development showed that: (1) the expert's assessment of the STAD cooperative model teaching materials (textbooks and LKM) with the blended learning method was feasible to use, (2) the trial results of the STAD cooperative model teaching materials with the blended learning method were practically used by lecturers and students in learning and effective for students mastering the material system of linear equations.

Abstract

The culture of giving children called ‘matamusan’ from the Tetun tribe is a local culture that should be for its authenticity and sacredness. The procession of determining the children of ‘matamusan’ contains ethnomathematical values not realized by the cultural legatees. This research aims to explore the ethnomathematical elements in ‘matamusan’ culture. In addition, this research can be beneficial at developing context-based mathematical learning materials and a reference in developing the operational curriculum of the education units in the autonomous learning curriculum, particularly in elementary schools. This research employs a qualitative-exploratory method using an ethnographic approach, while observation and interviews are used as techniques to collect data. Data analysis uses data reduction, data presentation, and conclusion. The results of this research show that there are six mathematical concepts  in the cultural procession of determining ‘matamusan’ children: (1) the concepts of one-dimensional geometry, namely a line consisting of horizontal lines, parallel lines, and acute angles, and two-dimensional geometry, namely rectangles and rhombus. (2) the concept of counting; 3) the concept of the median; 4) the concept of the unit of time; 5) the concept of the unit of weight and; 6) the concept of currency, which can be used to develop teaching materials on mathematical content, especially in elementary schools whose implementation is in the form of context-based mathematical problems..

Abstract

Participants can profit from the ability to solve issues by first understanding them, then choosing the best technique, and then applying it to problems in both mathematical and non-mathematical situations. Many variables contribute to students' inability to answer mathematical questions, one of which is a lack of confidence in their abilities. The purpose of this study is to describe how well-equipped pupils are to deal with arithmetic challenges associated with absolute value equations. Study participants were selected from each level after each level's self-efficacy was assessed using questionnaires. The tools used in data collection procedures, which are training tactics, include short interviews, self-efficacy questionnaires, and assessments of one's ability for solving mathematical problems. The data processing and analysis process have three stages: data reduction, data presentation, and conclusion-making. The research subjects were three students from each of the three self-efficacy levels—very high, high, and medium—and their propensities for resolving mathematical puzzles were then evaluated. Students with a very high level of self-efficacy perform mathematical problem-solving tasks more effectively than students with high and medium levels of self-efficacy.

Abstract

This study aims to describe students’ mistakes in solving number theory’s problem. In this study, error analysis, especially on the topic of Diophantine equations and Chinese remainder theorem. This type of research is qualitative research. The subjects of this study were 46 students of mathematics education at Sanata Dharma University. The data collection technique used a test. The data were analyzed to determine errors in doing number theory problems using the type of error according to Newman. According to Newman, five types of errors are reading, comprehension, transformation, process skill, and encoding errors. The conclusion of this study showed that the most errors made were related to process skill errors and transformation errors, while only a few experienced comprehension and encoding errors. None of the students made reading error.This shows that students already understand the meaning of the problem, but when changing and looking for solutions to problems an error occurs. The factors that may cause this error are a lack of understanding of the concept of the Diophantine equations and Chinese remainder theorem, as well as a lack of problem practice.

Abstract

One of the ways teachers design a learning environment is to use the right media in teaching a concept so that the concept is easily accepted and understood by students. Therefore, the author offers a solution to use the media or learning resources that exist in the environment of the students in this case ethnomathematics. There has been a lot of research from UKI Toraja that the culture of the Toraja people is rich in ethnomathematics. Therefore the author was inspired to use this in mathematics learning. In this study ethnomathematics will be packaged in student Worksheets. This is considered very appropriate because LKS, which contains instructions for the stages of solving a problem, will challenge students to solve it or find a concept in an interesting way because it uses media in Toraja culture, which is inseparable from the lives of students at SMP 1 Denpina or it can be said that the students are familiar with it. LKS which is based on Ethnomathematics, apart from being a learning medium that helps teachers convey messages to students, the use of ethnomathematics in learning is one way to maintain the local wisdom of the Toraja people so that the younger generation who are currently in the digital era still understand and even maintain the culture they have. This study aims to apply ethnomathematics-based student worksheets in mathematics learning in Schools. The research method used is a quantitative research method. Where in the stages, the author will design student worksheets based on ethnomathematics, then test its validity after it is used in the learning process and during the learning process, student activities will be observed to see the level of student activity during learning using LKS developed by the author. After the learning process is complete, students will be tested using a learning outcomes test. From the results of the study, it was found that the use of ethnomathematics-based LKS in grade VII students of SMPN I was effective, this can be seen from the learning outcomes and activities of the students studied meeting the effective criteria.

Abstract

This study will examine the orthogonal properties of Directional Short-time quaternion Fourier transform (DSTQFT) which is a further study of DSTFT with an expansion in the form of a function that has a Quaternion value. The orthogonal properties of DSTQFT are obtained by combining the orthogonal properties of  DSTFT and the Fourier quaternion transform (QFT). Based on the results of the study, it was found that the orthogonal nature of the Directional Short-Time quaternion Fourier Transform (DSTQFT) is different from the orthogonal nature of the Directional Short-Time Fourier Transform (DSTFT). In addition, there are three important consequences of orthogonality in TFQSTB as a result of the quaternion-valued function.
