Artikel ini berfokus pada eksplorasi pemahaman siswa dalam mengidentifikasi informasi atau hal-hal mengenai konsep perbandingan melalui cerita atau permasalahan serta untuk mengetahui sejauh mana siswa memaknai arti perbandingan senilai. Penelitian ini merupakan desain riset yang menggunakan pendekatan PMRI (Pendidikan Matematika Realistik Indonesia) dengan cerita sebagai konteks awal pembelajaran. Subjek penelitian ini adalah siswa kelas VII pada salah satu Sekolah Menengah Pertama di Palembang. Hasil penelitian menunjukkan bahwa penggunaan konteks cerita dapat membantu siswa mampu mengidentifikasi informasi atau hal-hal mengenai konsep perbandingan dan memahami arti perbandingan senilai. Penggunaaan cerita sebagai konteks awal pembelajaran dapat memberikan pengaruh yang positif pada pembelajaran matematika yang lebih menyenangkan, dan dapat meningkatkan pemahaman konsep matematika yang dipelajari.

This research was conducted so that educators can find out the location of student errors. In addition to these factors, there are many other factors that influence student errors in answering math story questions, one of which is the gender factor. The analysis used to find out what types of mistakes students made, here the researcher uses Newman's procedure. The type of research used in this research is descriptive qualitative research. The research subjects were 31 students of class XI Madrasah Aliyah for the test. Then in the interview 6 subjects (3 women and 3 men) were taken representing each category of high, medium, low for interviews. Subjects were selected through a short test given by the researcher, the results of the previous test scores and discussion with the Mathematics Teacher of the class. The results of the study showed that female students made more mistakes in the completion process error indicator. Then in the male category, they made more mistakes in the final answer writing indicator. When viewed from the many types of errors of male and female students, a conclusion can be drawn that male subjects are slightly superior in solving math problems than female subjects. This is because men have better mechanical and mathematical abilities but women are also more effective in terms of accuracy and accuracy in solving mathematical problems.

A realistic math problem is one of the math problems whose solution requires a reasoning habit. Reasoning ability will increase if students often practice their reasoning habits. By solving realistic math problems, it is expected that studentsâ€™ reasoning habits can be trained well. This study aims to describe the reasoning habits of class VIII students of MTs Sunan Kalijogo Kranding Kediri Regency, East Java, Indonesia in solving realistic math problems in terms of 4 stages of reasoning habits. This study uses a qualitative approach with a descriptive type of research. The data collection technique in this study used a mathematical reasoning ability test sheet and interviews that had been validated by four mathematics education experts and had met the valid category. The subjects in this study were students of class VIII F MTs Sunan Kalijogo Kranding, totaling 28 students, then three students with high, medium, and low categories of reasoning habits were taken to conduct interviews. The results of this study indicate that students with high-category reasoning habits can fulfill the four stages of reasoning habits. Students with reasoning habits in the medium category can fulfill two stages of reasoning habits. Students with low-category reasoning habits are not able to fulfill the four stages of reasoning habits.

Kemampuan representasi matematis merupakan salah satu kemampuan matematis yang dapat dicapai dengan menggunakan strategi atau pendekatan dalam pembelajaran, salah satunya adalah pendekatan RME (Realistic Mathematics Education). Tujuan dari penelitian ini adalah mengetahui hasil penerapan pendekatan RME (Realistic Mathematics Education) pada materi luas permukaan terhadap kemampuan representasi matematis yang ditinjau dari hasil penyelesaian LKPD (Lembar Kegiatan Peserta Didik). Subjek penelitian terdiri dari siswa SMP yang belum pernah mendapatkan materi luas permukaan bangun ruang sisi datar, terutama untuk bangun ruang balok dan prisma. Dengan menggunakan pendekatan kualitatif, hasil penelitian ini menunjukkan bahwa LKPD (Lembar Kegiatan Peserta Didik) berbasis RME (Realistic Mathematics Education) yang digunakan telah sesuai dengan prinsip dan karakteristik RME sebagaimana yang dikemukakan oleh Gravemeijer. Kesesuaian LKPD dengan karakteristik RME dapat ditunjukkan dari hasil jawaban siswa saat menyelesaikan LKPD secara berkelompok. LKPD (Lembar Kegiatan Peserta Didik) tersebut juga dapat mendorong kemampuan representasi matematis siswa yang terdiri dari tiga indikator, yaitu representasi visual, verbal, dan simbolik. Sehingga LKPD berbasis RME yang diimplementasikan pada materi luas permukaan mampu memfasilitasi kemampuan representasi matematis siswa.

Community diversity shows a nation that is rich in tradition and culture. Indonesia is a country of diverse ethnicity, race, and culture but we are still one called Bhineka Tunggal Ika. In the order of society, it is reflected in the form of tolerance practiced in the daily life of Sekaran Village. The multi-religious community that lives side by side makes researchers want to know their neighbors’ lives. The method used in reviewing this research is a qualitative approach, using a social fact paradigm. The results of the research are Sekaran is an exemplary village for people who have multiple religions and the practice of tolerance in neighboring life starts from the small things in the social environment. The conclusion obtained in this study is that the lives of neighboring communities of Sekaran are inseparable from the lives of the people in general, which is the difference between the people of Multi-Religion. The people’s life is very keeping the peace between religious groups which makes the village a model of religious tolerance in the Kayen Kidul Subdistrict.

This study focuses on analyzing the application of differential equations in modeling the population growth of Kediri City through a logistic growth model, and aims to predict the city's population for the years 2021-2030. Employing a literature study approach, this research utilizes secondary data sourced from the official website of the BPS (Central Statistics Agency) of Kediri City. The data encompasses population figures from 2005 to 2020. To ensure the accuracy of the population predictions made by the logistic growth model, a comparison with the official data from the Central Statistics Agency is necessary. A critical aspect of this research involves estimating the carrying capacity of Kediri City's population, which is identified as 295,672 individuals in the year 2030. The findings indicate a significant growth trend in the population, characterized by a specific growth rate. To validate the accuracy of the logistic growth model, the Mean Absolute Percentage Error (MAPE) method was applied, resulting in an error percentage that falls within the highly accurate category, thus affirming the reliability of the model in predicting population growth trends.
