<p><em>Ethnomathematics has developed and made a major contribution to learning mathematics. One of them is in improving students' mathematical problem solving abilities. The purpose of this study is to explore the ethnomathematics contained in the Agung Jami' Malang Mosque as a means of student learning in improving problem solving skills. The research methods used are ethnography and quantitative. The research instrument is the human instrument, the researcher is directly related to the research, as well as collecting research data through observation, literature, documentation, and tests. In addition, researchers analyzed quantitative data that had been obtained from the results of trials on elementary school students. From the research that has been done, it is found that the ethnomathematics contained in the Agung Jami' Malang Mosque is in the form of geometric shapes, including rectangles, tubes, semi-circles and other geometric shapes. From the results of the trials that have been carried out, it was found that the problem-solving ability of students increased when working on problem-solving problems with the help of ethnomathematics found at the Agung Jami' Malang Mosque.</em></p>

Problem-solving abilities have an important role in learning, especially in solving math problems, one of which is in circle material. This study aims to describe the mathematics problem solving process of junior high school students in solving circle problems through the process of solving problems in IDEAL. The approach used is a qualitative approach with a descriptive type. The sampling technique used in this research is purposive sampling technique. The results showed that, based on the problem-solving process, each subject had a different problem-solving process. S-1 with the category of completely solving problems fulfills the indicators in solving IDEAL problems. S-2 with the category of correct but not perfect does not yet fulfill the IDEAL problem-solving process. S-2 experienced errors when exploring the strategy and implementing the first problem strategy so that the final result was not in accordance with the objectives of the first problem. S-3 with the category of imperfect does not yet fulfill the IDEAL problem-solving process. S-3 only fulfills one IDEAL problem solving indicators, implementing strategies. However, the problem-solving process carried out by S-3 is not exactly in accordance with the objectives of the first and second problems.

<p>Integrative mathematics learning is needed in the study of science and religion, especially in the madrassa and the Islamic University, to improve morality for all students in Indonesia. This study aims to examine the hadith regarding integers and integer operations in integrative mathematics learning. Mathematical learning is expected to increase students' religious knowledge and mathematical knowledge. The method used in this research is literature study. In the hadith, some integers are 1,2,3,4,5,6,7,8,9,10 and integer operations, namely addition, subtraction, multiplication, and division. The hadiths related to numbers and number operations are HR. Bukhari 40; 71; 15; 33; 1334; 1761; 1109, HR. Muslim 19; 1984; 1513; 1991, HR. Darmini 3174, HR. Ibnu Khuzaimah 301, and HR. Tirmidhi 565.</p>
