Abstract

Abstract. Forecasting Indonesia's rainy and dry seasons is increasingly complex, requiring effective forecasting methods. This research is focused on rainfall forecasting in Jakarta, which includes Kemayoran Station and Tanjung Priok Station, using the Hybrid ARIMAX-ANN model. In ARIMAX modeling, the exogenous variable involved is the humidity variable. The accuracy results of the Hybrid ARIMAX-ANN model will be compared with the ARIMAX model. The results of this study show that the Hybrid ARIMAX-ANN model provides better accuracy. At Kemayoran Station, the Hybrid ARIMAX-ANN (1,0,0) model with 1 hidden layer shows a lower MAPE, 21.145%, than the ARIMAX model. Meanwhile, at Tanjung Priok Station, the Hybrid ARIMAX-ANN (1,0,0) model with 2 hidden layers has a lower MAPE, which is 37.416% compared to the ARIMAX model. The results show that the Hybrid ARIMAX-ANN model provides better accuracy than the ARIMAX model in rainfall modeling in Jakarta. Applying the Hybrid ARIMAX-ANN model at Kemayoran Station produces better accuracy than the application at Tanjung Priok Station.Keywords: ARIMAX, Hybrid ARIMAX-ANN, Rainfall

Abstract

This research aims to analyze the causes of students’ misconceptions in addition and subtraction with unlikedenominators, along with their solutions, based on a fishbone diagram. This study was qualitative research with a collective case study design. The research subjects were students who experienced misconceptions in adding and subtracting fractions with unlike denominators. The result of this research was caused by student misconceptions in addition to the subtraction of fractions, unlike denominators, which are classified based on six aspects in the fishbone diagram: man, machine, method, material, measurement, and environment. This causes errors in calculation operations involving numerators and denominators without equalizing fractions, the absence of visual aids for fractions that are unlike denominators, limited teacher mobility in teaching, and a non-conducive classroom atmosphere. Moreover, the language used in textbooks may not be relevant to students’ cognitive levels, and there may be subjectivity in teachers’ assessments of student answers. Peer tutors who provide incorrect explanations to their friends, the existence of certain friendship groups, and high-category students with low communication abilities. Understanding the causes of these misconceptions can be a reference for teachers to prevent misconceptions in students.

Abstract

Algebraic reasoning is essential for students to develop thinking systematically and analytically to conclude. This study analyzes students' algebraic reasoning levels about learning limit functions. The method used is a qualitative method with data collection techniques using algebraic reasoning tests on 23 first-semester students of the mathematics education study program and interviews conducted with one student from each of the high, medium, and low levels. Data analysis techniques in this study consist of data collection, reduction, presentation, and conclusions. In completing the algebraic reasoning test, students with high levels can fulfill four of the five indicators of algebraic reasoning. Students with a moderate level of algebraic reasoning can fulfill three of the five indicators of algebraic reasoning. Students with a low level of algebraic reasoning can fulfill four of the five indicators of algebraic reasoning. Students with high, medium, and low algebraic reasoning cannot find patterns, create patterns, and generalize patterns. Keywords: reasoning algebraic, function limit, generalized patterns

Abstract

Abstract. The aim of this research is to examine the effectiveness of a project-based learning model assisted by educational teaching aids, specifically construction blocks, on students' mathematical creative thinking skills. The research method employed is a pre-experimental design with a one-group pretest-posttest approach. The research instruments consist of observation sheets and student essay tests. Data analysis techniques include individual minimum mastery criteria (MMC) achievement tests, classical completeness tests, pretest-posttest mean difference tests, and N-gain tests. The individual MMC hypothesis test, using a one-sample t-test, yielded a significant value (2-tailed) of 0.000 < 0.05, indicating that after the project-based learning intervention with construction block educational aids, the MMC exceeded 70. The classical completeness test, utilizing Z statistics, resulted in Z_calculated = 3.560545 ≥ Z_table = 0.6736, demonstrating that the proportion of students meeting the minimum mastery criteria exceeded 75%. Furthermore, the mean difference test showed that students' mathematical creative thinking skills increased from 36.82 to 85.15. Additionally, the N-gain test yielded a score of 0.7675, with a percentage of 76.74%, categorizing it as high and effective. Therefore, project-based learning assisted by educational teaching aids, specifically construction blocks, is effective in enhancing students' mathematical creative thinking skills. Keywords: Construction blocks, students' mathematical creative thinking skills.

Abstract

Abstarct. This study aims to improve the learning outcomes of vocational high school (SMK) students in quadratic equation material through the implementation of the Teams Games Tournament (TGT) learning model. The research method employed was Classroom Action Research (CAR), conducted in three cycles, each consisting of planning, implementation, observation, and reflection. The subjects of this study were 10th-grade students at SMKS Muhammadiyah 4 Sukorejo Kendal. Data were collected through learning outcome tests and classroom activity observations. The findings indicate that the TGT model effectively enhances students' understanding of quadratic equations, as evidenced by the increase in average test scores and active participation in group discussions and academic competitions. This research supports the use of game-based cooperative learning to boost student motivation and academic achievement in vocational education. Keywords: Teams Games Tournament (TGT), learning outcomes, quadratic equations, classroom action research, vocational high school.
