Abstract

Real analysis is one of the most difficult subjects. Almost every student faces this problem even during lectures. The content is difficult to understand and confusion arises when choosing a theorem that can be used as a proof. The aim of this research is to conduct a literature review to find out the causes of student problems when studying anreal courses. The method used is the Systematic Literature Review (SLR) strategy. SLR is a research method that aims to identify, explore and interpret data in journals systematically and definitively. The research conclusion is that the problem that often occurs in practical lectures is that students have misconceptions about the material so it is difficult to prove it. There are four factors that influence this problem, namely factors originating from oneself, factors originating from the school environment, factors originating from the home environment, and factors originating from the local environment.

Abstract

Ethnomathematics is one of the approaches that integrates local wisdom with mathematics learning. This study aims to develop PBL-based LKPD with ethnomathematics nuances at the Maimun Palace. This research method is research and development (Research and Development). The development model used as the basis for this study is the ADDIE development model (Analysis, Design, Development, Implementation and Evaluation). The results of the study showed that the LKPD developed was included in the valid category, for the average overall result of the LKPD validation assessment from the three validators was 4.35. In the implementation, the response of students to the LKPD with an average score of 4.48 was categorized as very good and met the practicality of the LKPD, so it did not need to be revised again. The PBL-based LKPD with ethnomathematics nuances produced, along with its supporting instruments, have met the criteria of validity, practicality, and effectiveness.

Abstract

Production planning is one of the most important factors in improving business continuity. The preparation of production planning is related to the optimization of production for a particular business so that the business can operate efficiently and production activities achieve competitive prices. The preparation of production planning must consider several factors because every business has different goals that it wants to achieve. The Goal Programming method aims to minimize deviations from the targets set by the business, so that business goals can be achieved optimally. This research aims to optimize production in a company that can accomplish more than one goal. The method used in this study is Systematic Literature Review (SLR), and this study identifies 5 previous journals. The source of information used in this study is articles from national journals published between 2018-2024. The results of this study show that Goal Programming is a very effective tool in production and distribution planning in various industrial sectors.

Abstract

Computational thinking is the ability to solve problems and design systems using concepts and techniques generally associated with computers and computer programming. The aim of this research is to conduct a literature review, namely to determine the application of computational thinking in mathematics learning. The technique used is the Systematic Literature Review (SLR) strategy. SLR is a research method that aims to identify, study and interpret data in journals systematically with specified stages. The conclusion obtained from the research results is that the application of computational thinking in mathematics learning can be done using four foundations of computational thinking, namely: (1) Decomposition, namely the problem is divided into small parts, (2) Pattern recognition, namely the process of identifying patterns or sequences of problems, (3) Abstraction, namely consideration of the important parts of a problem, and (4) Algorithm, namely a series of instructions for solving the problem. Examples of its application include the use of interactive mathematics software, mathematical simulations, problem-based learning with technology, adaptive learning and the use of educational games.

Abstract

This study aims to develop a Brain-Based Learning-based LKPD on Single Variable Linear Equations for seventh-grade students at a private junior high school in Bandung. The method used is the ADDIE development model, which consists of five stages: Analysis, Design, Development, Implementation, and Evaluation. The results of validation by subject matter, media, and language experts showed that the LKPD developed was highly valid with an average score of 85.2%. The practicality test conducted by teachers and students yielded an average score of 83.47%, which falls into the highly practical category. Meanwhile, the effectiveness of the LKPD was measured through pretest and posttest tests, which showed an increase in learning outcomes with an average score rising from 56.52 to 80.09, as well as an N-gain score of 0.5855, which is classified as moderate. The classical mastery level also increased to 80.95%. Therefore, the Brain Based Learning-based LKPD is declared valid, practical, and effective in supporting the mathematics learning process and is able to improve students' conceptual understanding and learning activity. The results of this study are expected to be an alternative innovative teaching material that supports more contextual learning and is in line with how the brain works.
