Abstract
Interference can occur because of the existence of two or more information/knowledge, which is mixed. Interference is due to the similarity of information/knowledge that is close together. One of the material in SMP that allows interference is a proportion. This study aims to develop a proportion test instrument to identify students thinking interference in solving problems. The question instrument contained three questions, namely direct proportion and inverse proportion and two types of proportions in one question. The development process involves experts both in the field of mathematics and in the field of mathematics education so that instruments are valid questions. Also, the development process involved 32 seventh grade junior high school students in one of the junior high schools in Yogyakarta. The result is that the instruments developed are declared valid and can be used to identify students thinking interference in solving comparison problems. This is reinforced by the results of trials that of 32 junior high school students, six students were wrong in solving comparative problems of value, 17 students were wrong in the turnover ratio, and 14 students were wrong if both types of comparisons were present together. Of the students who experienced this error, there were more than 40% who indicated interference thinking.

Abstract
The third dimension is a subject that is still considered difficult for high school students, because students have not been able to understand the construction of images from three dimensions to two dimensional shapes. And the main factors that cause other students that make it difficult for students to learn the three dimensions of euclid geometric concepts based on 5 basic postulates that should be developed, but most teachers ignore this, because it is preferred to calculate the appropriate formula. This, limiting students to explore the science of geometry, plus the fear of students when trying to solve geometry problems. To bring up the high-level abilities of high school students, it is to provide motivation to learn, by providing stimulus to students about basic concepts that are easily mastered by students, and students are able to answer from the results of their own problem solving. Using the links 5 Euclid postulates help visualize students, students try to analyze the relation of geometric problems to postulates. After that, students express opinions from the results of the thinking process, reevaluate if something goes wrong, and make their own conclusions to solve geometry problems with the Geogebra Javascript. Third dimension learning is more interactive and interesting visually, so students are able to be motivated to deepen the three dimensions.

Abstract
Mathematics is a subject that must be mastered by everyone at various levels because every activity in everyday life, everyone must have something to do with mathematical problems. Once the importance of mathematics in each individual, the need for the introduction of mathematics is given to children from an early age. However, many are found in the field that students have not been able to master the basic concepts of mathematics are numbers at every level. As a result, the impact on other mathematical materials, so assumes that mathematics is the most difficult subject. With this problem, it can be overcome by using money learning media related to numbers, the goal is to help students easily understand about numbers that can be applied in daily life. Because it is limited to the time and cost of making media, the best step is the use of ICT, namely Powerpoint software using Visual Basic Application that makes money learning media more attractive, fosters students enthusiasm, and encourages students confidence to make appropriate decisions based on student experience in class and in the environment. The study was conducted to develop a VBA Powerpoint-based money media addressing the difficulties of elementary school students, to improve students understanding skills and dare to make the right decisions.

Abstract
Special needs children are children with characteristics that are different from disability in general without showing mental, emotional, or physical abilities. Special needs children find it difficult to define categories in understanding lessons and most of the views of the community state that children with special needs are considered as disabled children who cannot do anything. Especially in terms of academic achievement from language, mathematics and science. This can show that children with special needs cannot distinguish numbers properly so that errors occur in the calculation process. Even though mathematics is very necessary to apply it to daily life personally that develops society. Developing the ability to understand numbers, each student is given the opportunity to answer a different one to explain and the approach used is Open Ended. The teaching aids used are in the form of mathematics learning media created on Microsoft Excel based on VBA. VBA language functions so that images are more interesting and interactive so student learning independence and Self Efficacy learning outcomes are achieved.

Abstract
Adaptive reasoning is the ability of students to process thoughts received by students. It is used to solve problems that are received and share thoughts to convince acquired knowledge related to mathematics. This ability must be mastered by MI students so that mathematical concepts are mastered not only in the form of calculations but also in their application in daily life. In the era of Industry 4.0 mathematical communication can be improved by using various innovations and digital-based media, one of which is the Macromedia program. Learning Media Design is analyzed by the mix method approach. The subjects in this study were 20 MI students at MI Tarbiyatul Islam Ponorogo. Qualitative methods in this study were conducted to obtain forms of media that can improve students mathematical communication. The results of this study found that there were 4 aspects in improving communication skills, namely exercises in solving problems related to day-to-day life, understanding the material of integer counting operations, student self-confidence, and mathematical literacy writing skills. Quantitative methods of comparison are used to test the results of learning media that are made. After the results of the development there is an increase in students communication skills after using the media.
