Abstract

This research aims to determine the application of linear function concept in economics and business. A linear function is the simplest function because it only has one independent variable and has a power of one. This research is qualitative research that uses a literature study method with an exploratory approach. Data collection techniques are carried out by collecting valid secondary data sources from books, scientific journals and the internet. The research results show several linear function models, namely the demand function Qdx = -a.Pdx +b , the supply function Qsx = a.Psx +b , the market balance point from the linear equation Pdx = Psx , the consumption function C = C0 + cY , the savings function S = C0 + (1 - c ) Y, and the production cost function TC = TFC + TVC.

Abstract

Purpose: This study explores how cost structure analysis supports managerial decisions, aiming to enhance strategic and relevant cost accounting practices across diverse business sectors. Methodology/approach: This research uses the Systematic Literature Review (SLR) method based on the PRISMA protocol. Literature was retrieved from the Scopus and Web of Science databases for the period 2015-2025, with a focus on articles that discuss the relationship between cost structure, accounting information, and managerial decision making. Results/findings: The review highlights diverse cost analysis approaches—ABC, TDABC, optimization, and environmental modeling—that support strategic decisions. Despite benefits in pricing and resource allocation, challenges like data inconsistency and system complexity persist. Findings stress the importance of adaptable, integrated systems for effective cost management in dynamic environments. Conclusion: This study highlights the strategic role of cost structure analysis in managerial decision-making, supporting pricing, planning, and resource efficiency. Despite varied approaches like ABC and TDABC, challenges persist, data inconsistency, complexity, and limited organizational capacity. The findings stress the need for adaptive, tech-driven cost systems. Limitations: This study is limited to ten articles from Scopus and WoS, potentially restricting generalizability across industries, regions, and evolving cost structure practices. Future research should explore broader sectors to enhance the relevance and applicability of cost analysis in dynamic business environments. Contribution: This study contributes to managerial accounting by guiding practitioners, researchers, and educators in enhancing cost structure analysis for strategic decision-making across various industries.

Abstract

Ethnomathematics in mathematics education seeks to bridge abstract mathematical concepts with students’ cultural experiences, thereby enhancing the relevance and meaningfulness of learning. Traditional games represent a valuable cultural resource for contextualizing mathematics, and the Indonesian game congklak is widely recognized for embedding rich mathematical ideas within its structure and gameplay. This study aims to systematically review the mathematical concepts present in the congklak game and examine their implementation in mathematics education. A qualitative systematic literature review was conducted using articles retrieved from the Google Scholar database. The search applied specific keywords related to ethnomathematics, congklak, and mathematics education, with clearly defined inclusion and exclusion criteria. Ten peer-reviewed articles published between 2019 and 2024 were selected and analyzed through data reduction, organization, and synthesis. The findings show that congklak incorporates multiple mathematical concepts, including counting and number sequencing, arithmetic operations (addition, subtraction, multiplication, and division), geometry (plane figures, solid figures, and reflection), linear equations in one variable, and basic profit-and-loss concepts. The reviewed studies also report positive effects on students’ conceptual understanding, learning motivation, engagement, and critical thinking skills. In conclusion, congklak serves as an effective ethnomathematical learning medium that supports meaningful and contextual mathematics instruction while also contributing to cultural preservation and strengthening students’ awareness of mathematics in everyday life.

Abstract

The development of digital technology in education has encouraged the need for innovative learning media that are more interactive, contextual, and aligned with students’ needs. One promising effort is the integration of Augmented Reality (AR) technology with ethnomathematics, particularly Toraja carvings, to create more meaningful mathematics learning experiences. This study aims to develop AR-based mathematics learning media incorporating the ethnomathematical nuances of Toraja carvings and to examine its validity and practicality as a supporting tool for teaching mathematics in Grade IX of junior high school. The research employed a development study using the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The subjects consisted of 150 students from six junior high schools in Palopo City, selected through purposive sampling and random sampling techniques. The development process involved curriculum analysis, exploration of Toraja carving motifs relevant to geometric transformation topics, storyboard design and interactive flow development, and the creation of an AR prototype, which was then validated by experts and tested with students. The findings revealed that the developed media achieved an average validity score of 85.42%, categorized as highly valid, and an average practicality score of 77.82%, categorized as practical. These results indicate that the media is not only feasible in terms of content and presentation but also practical for use in mathematics learning. This study provides an innovative solution to enhance students’ engagement and to foster a more contextual and meaningful learning experience.

Abstract

This study aims to investigate the effectiveness of Augmented Reality (AR) learning media integrating Toraja carving ethnomathematics on the mathematical proficiency of ninth-grade junior high school students in Palopo. The research employed a quasi-experimental design using a pre-test and post-test model to measure the impact of AR learning media on students’ mathematical skills. The participants consisted of 150 students selected from six schools through purposive and random sampling techniques. The research instruments comprised a mathematical proficiency test and a questionnaire developed based on five indicators: conceptual understanding, procedural fluency, strategic competence, adaptive reasoning, and productive disposition. Data were analyzed using the Wilcoxon Signed-Rank Test, as the dataset was not normally distributed. The results indicate a significant improvement in students’ mathematical proficiency after the implementation of AR learning media, as evidenced by the significance value of the Wilcoxon Signed-Rank Test, which is 0.000 and lower than 0.05. The integration of AR technology with local cultural elements of Toraja carvings successfully fostered a contextual, interactive, and meaningful learning environment. This study implies that can serve as an innovative pedagogical approach to enhance mathematical proficiency while promoting the preservation and appreciation of local culture in mathematics education
