The process of solving mathematical problems requires thinking skills. Thinking skills needed to provide creative ideas in solving mathematical problems include critical thinking skills. The understanding of students in providing creative ideas is still low and the ability of students to identify a mathematical problem is still low. The purpose of this study was to determine the effect of learning intensity on the ability to think critically mathematically, to determine the effect of learning habits on mathematical critical thinking skills, to determine the effect of learning intensity and learning habits on mathematical critical thinking skills. This type of research is explanatory research. The results of this study, namely there is a positive influence on learning intensity on mathematical critical thinking skills, there is a positive influence on learning habits on mathematical critical thinking skills, there is a positive influence on intensity and learning habits on mathematical critical thinking skills. Keywords: intensity, habits, mathematical critical thinking INTRODUCTION Learning is needed by everyone, because learning can provide a person's experience in his life. Based on this, learning will provide changes in one's behavior. According Sudjana (2005: 5) suggests that learning is a process that is characterized by changes in a person. Changes in behavior that everyone has varies depending on the learning process carried out. Learning takes a technique or a way so that something that is received can be understood well, so that success can be achieved. According to Djaali (2009: 101) revealed the factors that influence success in the learning process include motivation, attitudes, interests, study habits and self-concept. According to Rana and Kausar (Budijanto, 2016: 18) argues that the main key to successful student learning is good learning habits. Meanwhile, according to Sardiman (Ristanti, 2016: 93) states that the learning intensity of students will determine the level of achievement of learning objectives, namely improving their achievement. Based on this, sufficient learning intensity and routine learning habits can provide a change in student learning outcomes. The process of increasing learning outcomes, students need to be equipped with certain abilities in dealing with various problems of everyday life. The problems often faced by students in the learning process are the ability to solve mathematical problems. The process of solving mathematical problems requires thinking mailto:dian.purwaningsih24@yahoo.com 116 Mathematics Education Journals Vol. 2 No. 2 August 2018 ISSN : 2579-5724 ISSN : 2579-5260 (Online) http://ejournal.umm.ac.id/index.php/MEJ skills. According to Selz (Suryabrata, 2004: 64) argues that thinking is an abstract activity, in a direction determined by a problem that must be solved Thinking skills needed to provide creative ideas in solving mathematical problems include critical thinking skills. According to Krulik and Rudnik (Abdullah, 2013: 72) suggests that critical thinking is grouping, organizing, remembering and analyzing the information needed, testing, connecting and evaluating all aspects of the problem situation. Based on the observations of student behavior towards the readiness to accept the material, it can be seen from the students' understanding in providing creative ideas and solving mathematical problems. The understanding of students is still low and the ability of students to identify a mathematical problem is still low. This can also result in low students' critical thinking skills. Based on the background of the problem, the objectives of this study are as follows: (a) to determine the effect of learning intensity on critical thinking skills, (b) to determine the effect of learning habits on mathematical critical thinking skills, (c) to determine the effect of learning intensity and habits learn about mathematical critical thinking skills RESEARCH METHOD This type of research is explanatory research (explanation) that is research that explains the position of the variables studied and the relationship between one variable with another variable (Sugiyono, 2011). This research approach is a quantitative approach. This research was carried out at the University of Civilization in the 2017/2018 school year. The population of this study were students of Mathematics Education Department of the University of Civilization in the sixth semester of Academic Year 2017/2018. Independent variables (independent variables) in this study are learning intensity and study habits. The dependent variable (dependent variable) in this study is the ability to think critically mathematically. The research instruments used were observation sheets, questionnaire sheets and test sheets. Data collection was carried out by questionnaire method, observation method, and test method. Analysis of the data used in this study is a regression analysis test. RESULT AND DISCUSSION In this study a regression test analysis was conducted to determine the effect of learning intensity and learning habits on the communication skills of mathematical critical thinking. This analysis test uses SPPS. 1.
