INTRODUCTION
Progress on education world continue including the development of curriculum .The curriculum is all education experience given by the school to all students, either in school or outside school ( suryosubroto, 2004 ).The 2013 curriculum is the latest curriculum in which place students to become the learning centers and teachers only as facilitators.Curriculum 2013 aims to train student independence and improve students' activeness in learning process.The learning process in Curriculum 2013 teachers are required to act as motivators and facilitators so that students become learning centers.
But not all teachers have such competence and lack of time to prepare for learning maturely is one of the obstacles faced (Alawiyah, 2015).In the development of curriculum also demanded teachers can adjust methods used.Based on the regulation of ministry of education and culture number 65 concerning about the standard process,the learning models primary for the implementation of 2013 curriculum are Based on the research that has been done in the implementation of PBL there is increasing participation and activeness of student discussion.The average increase in the percentage of participation and activeness of the students' discussions indicates that there is a change in student behavior in teaching and learning activities to be better and there can be concluded that PBL is an effective learning model (Sholihah, 2010).In this study the selected learning model is Problem Based Learning (PBL).The Problem-Based Learning Model is one of the learning models of the scientific approach.Students are given a problem to solve themselves with the teacher only as a facilitator.The use of problems in relation to the real world allows students to understand the existing problems so that students more easily understand the material to discuss and create the learning process more effective.
Problem Based Learning is a learning that uses real-world problems as a context for students to learn self-confidence and problem-solving skills as well as to acquire knowledge and concepts that are the essence of the subject matter.This learning can provide an opportunity for students in exploreing, collecting and analyzing data so that students can be confident which includes: analysis, synthesis, and evaluation (Rusman, 2010).According to Pitadjeng the characteristics of problem-based learning as follows: a) the submission of questions or social problems; B) focusing on the interrelationship between the problem and the real world; C) the investigation is authentic; D) produce the product / work and display it; And e) cooperation among students in finding solutions (Pitadjeng, 2008).

RESEARCH METHODS
This study aims to analyze the results of treatment of research subjects.Because in this study there is no element of manipulation, which will only describe the results and analyze the data obtained.So research is descriptive research, that is a kind of research which attempts to describe phenomenon / event naturally.To get maximum result in this research using qualitative and quantitative approach.This approach has chosen because of data will of the process is the result of the problem based learning study results of students and data the interviews and questionnaire.In this study using quantitative research methods.This method can be interpreted as a research method based on positivism philosophy, used to examine the population or a particular sample, sampling techniques are generally done randomly, data collection using research instruments, data analysis is quantitative or statistical (Sugiyono, 2011).Research subjects or respodents of this research are students of class XI IPA 1 MAN Batu City.In class XI Science 1 consists of 6 male students and 27 female students with a total of 33 students.This study aims to collect data about the response, motivation and student learning outcomes.Therefore, at the time of the learning process conducted observations of student activities that focus on the response and motivation of students.After observation of the learning process will be conducted interviews and questionnaires to get data about student responses and motivation.
Furthermore, the response and motivation data which is along with the student learning result data will be further analyzed.
Data processing response and more motivation using qualitative data analysis while data of student learning result which is quantitative data will be processed using quantitative / statistical data analysis.The data which is will be analyzed using quantitative data analysis (descriptive statistics) and qualitative data analysis.The data uses questionnaire, interview, observation and test, before the collection tool used was tested the validity and reliability of the questionnaire by using SPSS and there were obtained that each questionnaire is valid with the value (0.6319) and the results of the test reliability states that the reliable questionnaire with > (0,970 > 0,4683).

RESEARCH RESULTS AND DISCUSSION
The results of this study obtained data response, motivation, learning outcomes and learning process.The result of questionnaire that has been processed obtained student response to learning mathematics using Problem Based Learning as in Table 1. the problems they encounter.From the questionnaire it is found that the amount of = 22,54, 16< so that the student's motivation level uses High Problem Based Learning.By the high motivation of students to learn mathematics by using PBM addressed under the PBM can be used as an alternative that gives a positive influence on students.
Student learning outcomes data obtained from the value of LKS, the value of exercise questions and daily test, the three values obtained are processed into the final value with the final value = .The final value is presented in a histogram and processed using SPSS to find out the mean, median, mode, quartiles, standard deviations and variety.
