Abstract

This research aims to determine the probability of changes in grades from the prerequisite course Mathematical Statistics II using the Markov chain process method. Prerequisite courses are an important component in the higher education curriculum, because they influence student success in advanced courses. In this study, student grade data was collected and analyzed to map the transition between grade categories from one semester to the next. The Markov chain model is applied to predict patterns of value change, with the assumption that the future state of value depends only on the current state. It is hoped that the results of this research will provide insight into the pattern of grade transition, assist in academic decision making, and identify factors that contribute to an increase or decrease in student performance. Thus, this study can contribute to improving learning strategies and more effective academic policies.

Abstract

Poverty is a fundamental problem that is the center of attention of the government in any country. The aim of this research is to analyze the influence of education, unemployment, the Covid-19 pandemic and the human development index on poverty in North Sumatra. The data used in this research is secondary data based on time series available on the official website of the Central Statistics Agency in North Sumatra. This research data processing uses the help of SmartPLS 3 software. The research analysis used in this research is Structural Equation Modeling which shows that the variables education, unemployment, the Covid 19 pandemic and the human development index are exogenous variables and poverty is an endogenous variable. The research results obtained an R-Square value of 0.511 or 51.1%. The large value of the coefficient of determination shows that the independent variables consisting of education, unemployment, the Covid-19 pandemic and the human development index are able to explain the dependent variable, namely the poverty percentage of 51.1%. Meanwhile, the remaining 48.9% is explained by other variables not included in this research model. The human development index variable has a negative and significant effect on poverty of 0.678. For the Covid 19 Pandemic variable, it has a negative and significant effect on poverty of 0.267.

Abstract

The low understanding of mathematical concepts experienced by students also has an impact on students' ability to solve problems related to mathematics because the concepts taught by teachers are never found in everyday life. Therefore, a learning approach is needed that encourages students to construct their own mathematical concepts based on experiences that occur in everyday life. The research method used in this research is Systematic Literature Review (SLR). The data collection process includes collecting and analyzing every published article and book that discusses mathematical concepts and the application of Realistic Mathematics Education (RME). The journals used in this research are national and international journals indexed by SINTA and SCOPUS. Research findings show that the RME approach has an important role in improving students' ability to understand mathematical concepts in several materials at every level of education.

Abstract

Viewed through the lens of arts and culture course results, students' cognitive capacities This is because classrooms are still using ineffective methods of instruction that discourage students from working on their skills in a variety of settings. The purpose of this study is to use the problem-based learning (PBL) approach to education in the arts and cultural topics (music arts) with the objective of enhancing students' cognitive capacities. The four phases of classroom action research (1) planning, (2) implementing, (3) observing, and (4) reflecting make up the study methodology. Observation and multiple-choice tests are two methods used to gather data. Qualitative and quantitative descriptive methods are used in data analysis. There was an increase from 34 students in the first cycle who finished the KKM to 36 students in the second cycle, indicating that students' cognitive abilities improved. It follows that students' cognitive capacities may be enhanced by the problem based learning (PBL) model's implementation

Abstract

This study aims to gather sufficient information about the sexagesimal base 60 number system. This research method is a literature study that collects some previous studies to answer about the sexagesimal base 60 number system. The results of this research show that the sexagesimal or sixtieth number system is the same calculation as Babylonian people's astronomical calculations, in their use sexagesimals can be said to be easier to use than decimal numbers, and to this day the sexagesimal number system is still used in a modified form to measure time, angles, geographic coordinates, and is still used in the field of astronomy.

Abstract

Learning difficulties do not only occur in students attending primary to secondary school, but also occur in mathematics education students. This research uses the Systematic Literature Review research method. Mathematics education students are part of the teaching faculty who are hired to become educators, namely the inability to understand the material, this main factor is the main factor in the difficulty of learning mathematics, students in the first semester are vulnerable to semesters 1-3 where the learning method is between schools. and different lectures make students in the first semester of mathematics education experience a shock of understanding, students are required not only to gain understanding in lecture classes but also in seminars, presentations and research, this study concludes. But one of the main factors is external where jockeying has a domino effect Mathematics education students must be aware of this so that they do not become students who are dull in thinking, logic and the future. The author states that no matter how smart the student is, if they still use assignment coaching services, they can be said to be suffering from an illness as is another definition of learning difficulties..

Abstract

The study aimed to investigate the alkaloid content in cinnamon (Cinnamomum burmannii) powder using the Soxhlet extraction method. Alkaloids are organic chemical compounds widely found in nature as secondary metabolites in both plants and animals. They possess a cyclic structure containing one or more basic nitrogen atoms, conferring unique basic properties. The research was conducted to provide a deeper understanding of the potential utilization of plant-derived alkaloids, particularly from cinnamon, in drug development. The study sought to determine the color of the precipitate formed in the extraction solution after the addition of Mayer's reagent and to investigate the effect of the number of Soxhlet extraction cycles on the color of the ethanol used in the research with cinnamon samples. The findings from this study contribute to the exploration of the alkaloid content in cinnamon and its potential applications in pharmaceutical development.
