Abstract

This study aims to analyze students' errors in solving literacy and numeracy problems based on Kastolan's stages and to identify the factors that contribute to these errors in order to minimize them during the learning process. This research employs a qualitative method with a study case. The subjects selected were six students out of a total of 36 students in class X-2 at SMAN 94 Jakarta. The results of the study indicate that the level of students’ literacy and numeracy skills influences the types and frequency of errors made. The conclusion reveals the factors behind each type of error: (1) conceptual errors occur due to a lack of understanding of the material and basic concepts, which leads students to choose incorrect formulas; (2) procedural errors arise from students’ inability to organize the steps of problem-solving in a sequential and systematic manner; and (3) technical errors result from inaccuracy in modeling the problem into mathematical form, such as writing incorrect variables or numbers.   Keywords: Erros Analysis, Kastolan Stages, Literacy and Numeracy Issues

Abstract

This study aims to examine the influence of the Realistic Mathematics Education (RME) approach and students' learning activities on mathematics learning outcomes. The method used is a quantitative approach with a true experimental design, comparing an experimental class that received treatment using the RME approach with a control class that received conventional instruction. The population in this study comprised eighth-grade students at SMP Muhammadiyah Al-Kautsar in the 2024/2025 academic year. The sample was randomly selected using a random sampling technique, resulting in class VIII A as the experimental class and class VIII B as the control class, each consisting of 32 students. The material taught was the Pythagorean Theorem. The instruments used in the study were an essay-based learning outcome test consisting of three questions and a student learning activity questionnaire containing 20 statements. Hypothesis testing was conducted using two-way ANOVA with a significance level of 0.05. The results indicated that the significance value for the interaction between the learning approach and learning activity on student learning outcomes was 0.509 (> 0.05), meaning there was no significant interaction between the two variables. However, both the RME approach and learning activities individually had a significant effect on students’ learning outcomes. In conclusion, the application of the RME approach and the improvement of students’ learning activities can individually enhance mathematics learning outcomes. While the combination of these two factors did not show a statistically significant interaction, each contributed positively on its own.   Keywords: RME Approach, Learning Activities, Learning Outcomes, Realistic Mathematics Education.

Abstract

This study aims to (1) classify cryptocurrencies based on the integration of market data and on-chain data to provide a more accurate mapping of digital asset characteristics. The method used is Multi-Channel Clustering, which enables the combination of multiple data views (multi-view) in the clustering process. The data includes market capitalization, trading volume, percentage gain, and volatility from the market data channel, as well as coin supply and active addresses from the on-chain channel. All data were normalized using the Min-Max Normalization method to ensure scale uniformity across variables. The clustering process was carried out using a K-Means algorithm adapted for the multi-channel context. The results of the study identified three main clusters: Cluster 1 contains coins with medium to low market and on-chain activity characteristics such as Tron and Cro; Cluster 2 includes coins with high volume and significant on-chain activity but not dominant, such as Ethereum and Solana; and Cluster 3 consists solely of Bitcoin, which has a unique profile in both channels. In conclusion, the Multi-Channel Clustering method proves effective in producing a more comprehensive classification of cryptocurrencies and can serve as a decision-support tool in highly volatile and complex market environments.  Keywords: Cryptocurrancy, Classification, Multi-Channel Clustering.
