INTRODUCTION
One of the important figure in university is lecturer. Lecturer represents the key person in class. Lecturer leading and instructing activity of student study. Lecturer has most relating to student compared to the other personnel. For student, lecturer is somebody owning authority, not only authority in academic but also in nonacademic. In society, lecturer performance as a model. Lecturer as counselor and instructor in learning.
Based on the result of observation, statistics achievement of student of mathematics education of Universitas Muslim Maros is low. This matter visible from average of daily restating grade, mid of semester and general examination of mathematics lecture for student at this university. Based on result interview, most students open the opinion that the ways of teaching of all lecturers are different so that it causing the happening of degradation results of learning.
Students represent the social and individual creature. As individual creature, each student has a lot of difference. These differences cause the view, opinion and student assessment to lecturer in learning are different each other. Therefore, there are different ideas from each student that writer interview. Some student confess prefer to lecturer so that diligent to follow the subject but there are also student confessing to become lazy follow the lecturer subject because they are not interesting to the lecturer.
Based of the problems above, the researcher want to do research with the title "Relation between Student's Perceptions to the Statistics Lecturer in Learning Process with Statistics Achievement of Students". Based on the background, problem statements that will be research are: 1. How about perception of students semester V of Mathematics Education Universitas Muslim Maros to the statistics lecturer? 2. How high of statistics achievement of students semester V of Mathematics Education Universitas Muslim Maros? 3. Are there positive relations between student's perception to the statistics lecturer in learning process with statistics achievement of students semester V of Mathematics Education Universitas Muslim Maros?

METHOD
This research is ex post facto, it means from what is done afterwards'. In the context of social and educational phrase means 'after the fact' or retrospectively' and refers to those studies which investigate possible cause and effect relationships by observing an existing conditions or state of affair and searching back in time for plausible causal factors. In this research, there are two variable that are student's perception to the lecturer in learning process as independent and statistics achievement of student semester V of the Department of Mathematics Education of Universitas Muslim Maros as dependent variable.
According to Cohen (2000), we earlier referred to the two basic designs embraced by ex post facto research, the co-relational (or causal comparative) models. We return to them again here in order to consider designing both typed of investigation. As we saw, the causal model attempts to identify the antecedents of the present condition and may be representing thus: Therefore, statistics achievement is test score that achieve from statistics test achievement in cognitive.
In this research, there are two instruments, which are (1) questioner, and (2) test achievement. of statistics. To measure student's perception to the lecturer in learning process, researcher use questioner that consist of scale of statement as perception to the lecturer in learning process. To measure statistics achievement, by using test of statistics achievement about statistics problem. Both of them give to the students directly and then filling and doing by them.
Questioner using to collect data from independent variable and statics achievement using to collect data of dependent variable. Data that got from respondent as a primer data. Result from filling the questioner then scoring by scoring procedure to change likert scale to become interval scale. These final score can be data of research for independent variable. While statics achievement test scoring as data of dependent variable.
This research uses two statistic techniques to analyze the data that are descriptive statistic and inferential statistic. Descriptive analyze for data of student's perception to the lecturer which are deviation standard, maximum, minimum and getting characteristic of data in this research.
For classification of statics achievement of students using classification with 5 scales, which are: For Inferential, suitable to the aim of research, that is to know the relation between independent variable (student's perception) and dependent variable (statics achievement of students), so that inferential statistic which use is correlation of product moment analysis. Hypothesis test by using SPSS software.

Descriptive Statistics Analysis
Finding of analyze data by descriptive statistic shown description of data in table and histogram.

Student's perception to the lecturer in learning process
Results of descriptive analyze which relate with score of independent variable (student's perception) shown in table:  According to score category of perception table above, known that generally perception of students semester V of Mathematics Education of Universitas Muslim Maros to lecturer is very positive with percentage is 60% (18 of 30 respondents).
Next, frequency distribution of student's perception is shown on graph as follow:

Inferential Statistics Analysis
Inferential statistic present pre requites, that are normality test and linearity test and then result of hypothesis test.

Normality test
Normality test to student's perception shown that significant value is , it means that data perception of students semester V of Mathematics Education Universitas Muslim Maros is normal.
Normality test to statistics achievement of student shown that significant value is , it means that data of statistics achievement of student semester V of Mathematics Education Universitas Muslim Maros is normal.

Linearity test
Independent and dependent variable is linear if level of significance less than probability ( ). Linearity test of relation between student's perception to the statistics lecturer in learning process with statistics achievement of students semester V of Mathematics Education Universitas Muslim Maros shown that Flinierity is 20,333 with level of significance Flinierity is 0,003 , it means relation is linear.

Equation of regression that used is simple equation of regression that is '
, where and , hence equation of regression ' .

Hypothesis Test
Ho : there is no relation between student's perceptions to the lecturer in learning with statics achievement of students semester V of Mathematics Education of Universitas Muslim Maros Ha: there are relation between student's perception to the lecturer in learning and process with statics achievement of students semester V of Mathematics Education Universitas Muslim Maros Based on correlation analyze by SPSS software, coefficient of correlation rcal is 0,594. If compare with rtable with N = 30 in level of significance 0,05 is 0,349. It coefficient have sufficient correlation. It shown that rcal > rtable, hence Ho is dishonor and Ha accepted. Thereby there are relations between student's perceptions to the lecturer in learning process with statics achievement of students semester V of Mathematics Education of Universitas Muslim Maros.
From analyze, known that determination coefficient is 0,353, it means that affectation of variable student's perception to lecturer is 35,3% and 64,7% affected by another variable.
Equation of regression that used is simple equation of regression that is, and , hence equation of regression ' ..
Coefficient b explains direction of change average of statics achievement for each alteration of variable student's perception. Its alteration is increase if value b is positive and decrease if b negative. From analyze, getting b positive, it means that every variable of student's perception increase one, average of variable statics achievement of students semester V of Mathematics education at Universitas Muslim Maros increase 0,297.

Discussion
Based on analyze by descriptive statistic can explain that generally students semester V of Mathematics education at Universitas Muslim Maros have positive perception. So do statics achievement of students. Generally, statics achievements of students are good.
After analyze the data by inferential statistic for research about relation between student's perceptions to the lecturer in learning process with statics achievement of students semester V of Mathematics education at Universitas Muslim Maros with coefficient rcal is 0,594. It shown that there are relations between student's perceptions to the lecturer in learning process with statics achievement of students semester V of Mathematics education at Universitas Muslim Maros. But then, it appertained in sufficient correlation. Besides it, getting coefficient determination 0,353 means that affectation of variable student's perception to teacher has certified is 35,3%. Whereas 64,7% affected by another by another variable.
Equation of regression that used is simple equation of regression that is, and , hence equation of regression ' . Its alteration is increase if value b is positive and decrease if b negative. From analyze, getting b positive. Coefficient b explains direction of change average of statics achievement for each alteration of variable student's perception. From analyze the value b is 0,297 (positive) its alteration is increase. It means that there are positive relations between student's perceptions to the lecturer in learning process with statics achievement of students semester V of Mathematics education at Universitas Muslim Maros. From analyze, it means that every variable student's perception increase one, average of variable statics achievement of students semester V of Mathematics education at Universitas Muslim Maros increase 0,297. From this finding, in shown that if lecturers have cognitive, openness psychology, and good behavior, will be effective influence the student included statics achievement. This finding analogous with explanation of Slameto (in Nugrahani, 2010), pass through of good relation between lecturer and students, students will be loved their lecturer and then will be loved their subject that lecturer gave until the students try to learn of it as well as possible. The other way, if students abhor their lecturer, then they will be reluctant to learn the lesson that lecturer gave. This finding supported too by Astuti (2010) that shown that positive perception can see from positive cognitive assessment and opinion of students to their lecturer. Cognitive and opinion aspect of students is a very important thing. When the students doing something with comfortable, hence given positive impact. Sympathy not occurs from rational logic, but based on opinion like identification process. Interesting to lecturer behavior will be motivated students to more understanding and make good relation until can occur cooperative with their lecturer.

CONCLUSION
According to finding, conclusions of this research are: (1) Generally perception of students semester V of the Department of Mathematics Education at Universitas Muslim Maros are very positive, (2) Generally statics achievement of students semester V of the Department of Mathematics education at Universitas Muslim Maros are very good, (3) There are positive relations between student's perception to the lecturer in learning process with statics achievement of students semester V of mathematics education at Universitas Muslim Maros.
