was conducted at Asy-Syifa Al-Inayah Middle School, Jambi City, with the aim of obtaining a description of student representation in solving mathematical problems. Subjects in this study were selected using purposive sampling based on visual, auditory and kinesthetic learning styles. It is hoped that this research will provide benefits in improving mathematics learning. The results of the research show that the representation of auditory students and visual students in solving mathematical problems each fulfills three indicators, while kinesthetic students only fulfill two indicators of mathematical representation. In presenting information, visual and auditory subjects each tend to present it in the form of images (geometry or number patterns) and create situations based on the problem given. Meanwhile, kinesthetic subjects tend to only create images to clarify problems and facilitate their resolution. In solving problems, both visual and auditory subjects are able to solve problems by making patterns based on the problem given and making conclusions from a pattern. It's just that auditory subjects can shorten problem solving steps by using mathematical expressions. Meanwhile, kinesthetic subjects experience problems in solving combinatorics problems, where they are unable to present images or patterns that can help solve the problem.

s business faces the challenge of unpredictable monthly fluctuations in consumer demand, which often lead to supply imbalances, overproduction, or lost profit opportunities due to stockouts. This study aims to implement and analyze the accuracy of the Single Moving Average (SMA) quantitative forecasting method in predicting Sate Padang Hapis sales volumes for June 2026. Model performance was evaluated by assessing mathematical accuracy across two time-interval variations: 3-month and 5-month moving averages. Projection error rates were rigorously measured using Mean Absolute Deviation (MAD), Mean Squared Error (MSE), and Mean Absolute Percentage Error (MAPE) parameters. The analysis reveals that the Single Moving Average model with a 5-month interval yields projections closest to actual data, achieving the lowest error rates (MAD: 28.00; MSE: 1,304.00; MAPE: 2.28%). Implementing this forecasting model provides management with an objective basis for decision-making, enabling the effective and efficient optimization of raw material logistics and supply management.

systematically. Empirical conditions in schools indicate that junior high school students’ critical thinking skills remain relatively low because science learning is still predominantly teacher-centered and insufficiently engages students in scientific investigation activities. This study aimed to determine the relationship between science process skills and the critical thinking skills of eighth-grade students at SMP Negeri Tindaret on the topic of the human excretory system. The study employed a quantitative approach with a correlational research design. The research sample consisted of 25 students selected through purposive sampling techniques. Data were collected using a critical thinking skills test and an observation sheet assessing science process skills. Data analysis was conducted using descriptive statistics and the Pearson Product-Moment correlation test. The findings revealed that students’ critical thinking skills obtained a mean score of 75.80, while science process skills achieved a mean score of 73.00, both categorized as fairly good to high. The correlation analysis produced a coefficient value of 0.732 with a significance level of 0.000, indicating a strong and significant positive relationship between science process skills and students’ critical thinking skills. The findings further demonstrated that students who actively engaged in observation, experimentation, data processing, and scientific communication exhibited better analytical abilities and conclusion-drawing skills. The novelty of this study lies in revealing the empirical relationship between science process skills and critical thinking skills specifically in the topic of the human excretory system at SMP Negeri Tindaret, as well as in providing recommendations for science learning based on scientific investigation to strengthen students’ higher-order thinking skills in the twenty-first century.
