This study was motivated by the low mathematics learning outcomes of students on the Pythagorean Theorem material, as indicated by difficulties in understanding concepts and low student participation during the learning process. The instructional media used by teachers have not been able to optimally attract students’ attention; therefore, alternative learning media that are more engaging and easier to understand are needed. This study aims to determine the effect of comic-based learning media on the mathematics learning outcomes of eighth-grade students at SMP Negeri 1 Lembar in the 2025/2026 academic year. This study employed a quantitative approach using a Posttest-Only Control Group Design. The research sample consisted of two classes selected using the cluster random sampling technique, namely class VIII B as the experimental class consisting of 33 students and class VIII D as the control class consisting of 32 students. The experimental class was taught using comic-based learning media, while the control class received instruction without the use of comic media. Data were collected through a posttest administered after two learning sessions and analyzed using descriptive statistics, an Independent Samples t-test, and effect size calculations. The results showed that , which is greater than , indicating a significant difference in learning outcomes between the two classes. The mean learning outcome of the experimental class was higher than that of the control class, with an effect size of 1.381, which falls into the large category. Thus, comic-based learning media have a positive and significant effect on students’ mathematics learning outcomes.

The high volatility of the Indonesian capital market (JKSE) poses significant challenges for investors in decision-making. Classical linear forecasting methods are often inadequate due to their inability to capture heteroskedasticity and asymmetric responses in financial data. This study aims to systematically compare and select the best hybrid model combining ARIMA with various GARCH specifications (Standard GARCH, EGARCH, GJR-GARCH, and TGARCH) under different error distributions, and to forecast JKSE price movements for the next three months. Using weekly closing price data from November 2022 to November 2025, the evaluation based on the lowest Akaike Information Criterion (AIC) identifies the ARIMA (0,0,4)-GJR-GARCH model with a Normal distribution as the most robust specification. This finding confirms the presence of a leverage effect in the Indonesian stock market, where volatility responds more intensely to negative shocks than to positive ones. The model demonstrates high accuracy with an RMSE of 2.090. The forecast projects a short-term correction followed by a gradual upward trend reaching the 8,603.62 level by March 2026, accompanied by widening confidence intervals that indicate increasing uncertainty risks in the future.

Conceptual understanding is a crucial foundation in algebra learning, particularly in the topic of Systems of Linear Equations in Three Variables (SLETV), which requires mathematical representation, logical reasoning, and appropriate procedural selection. This study aims to analyze students’ errors in conceptual understanding when solving contextual SLETV problems based on the error analysis theory proposed by Clements and Ellerton. A qualitative descriptive approach was employed involving 36 tenth-grade students from a senior high school in North Jakarta. Data were collected through a conceptual understanding test as a preliminary study and a contextual SLETV problem-solving test as the main instrument. Two students were selected as key subjects, representing high and low levels of conceptual understanding. The findings indicate that students with high conceptual understanding made relatively minimal and partial conceptual errors. In contrast, students with low conceptual understanding predominantly exhibited conceptual, procedural, and application errors. Furthermore, the ability to represent concepts mathematically and to select and apply appropriate solution procedures emerged as the weakest indicators. These results confirm that insufficient conceptual understanding significantly contributes to students’ errors in solving contextual SLETV problems.

This study aims to explore ethnomathematical concepts embedded in the architectural structure of Candi Arjuna in Banjarnegara Regency as one of the Hindu cultural heritage sites in Central Java. The research employed a qualitative approach using an ethnographic research design, focusing on revealing mathematical meanings within the context of local culture. Data were collected through direct observation of the research object, limited interviews with relevant parties, and visual documentation of the temple’s architectural elements. The data were then analyzed descriptively using qualitative analysis procedures, including data reduction, data presentation, and conclusion drawing. The findings indicate that the front façade of Candi Arjuna implicitly integrates various mathematical concepts, including rectangular and triangular plane figures, vertical symmetry, and tiered patterns in the stepped-pyramid structure. The regularity of forms, uniformity of dimensions, and balance in the building’s composition demonstrate the application of contextual and meaningful mathematical principles within the cultural practices of the society at that time. These findings confirm that the architecture of Candi Arjuna is not only of historical and aesthetic value but also holds potential as a contextual ethnomathematics-based resource for mathematics learning that is closely connected to students’ cultural environments.

Tuberculosis (TB) remains a major public health problem in Indonesia, with West Java Province contributing the largest share of national cases. Understanding temporal dynamics of TB cases is essential to support disease control planning. This study aims to analyze the temporal pattern and short-term forecasting of tuberculosis cases in West Java Province using the Autoregressive Integrated Moving Average (ARIMA) model. Secondary time-series data of TB cases from all districts and cities in West Java during the period 2019-2023 were used and aggregated at the provincial level. Model identification was conducted through stationarity testing and analysis of autocorrelation and partial autocorrelation functions. The best-performing model was selected based on information criteria and residual diagnostics. The results indicate that ARIMA(1,1,1) is the most suitable model for representing the temporal dynamics of TB cases. Forecasting results for the next six months show a relatively stable trend without extreme fluctuations, although the predicted number of cases remains high, particularly in densely populated urban areas such as Bogor Regency, Bandung City, and Depok City. These findings demonstrate that ARIMA provides a simple yet effective approach for short-term forecasting of TB cases and can support provincial-level planning and decision-making in tuberculosis control programs.

Rainfall is a hydrometeorological phenomenon that has complex seasonal patterns and temporal fluctuations. This study aims to model monthly rainfall in West Java Province using the Seasonal Autoregressive Integrated Moving Average (SARIMA) approach based on 2015–2024 data. The research stages include data stationarity analysis, model order identification, parameter estimation, and residual diagnostic tests to ensure model validity. The best model selection is carried out by comparing the Root Mean Square Error (RMSE), Mean Absolute Error (MAE), and Mean Absolute Percentage Error (MAPE) values. The analysis results show that the SARIMA model is able to represent seasonal patterns and monthly rainfall dynamics with a good level of accuracy. This model is expected to be a reliable mathematical basis for monthly rainfall forecasting in West Java Province.
