Abstract :Most students consider mathematics is a difficult subject, and it becomes a challenge for the teachers to teach the subject in a good way. Therefore, future mathematics teachers need selfefficacy in teaching the subject. This research aims to find out the effectivity of field experience practice to increase teaching selfefficacy in 15 students of Mathematics Education Program, Teaching and Education Departement of Universitas Pekalongan, Semester VII 2017/2018 period. This research implemented experiment method with the one group pretestposttest design. Teaching selfefficacy variable was measured by Teaching SelfEfficacy Scale which was tested to 105 students of Teaching and Education Departement Universitas Pekalongan semester VII, the result of aplha croncbach reliability coefficient was 0,966. This research showed a significant increase in teaching selfefficacy mean for 23,76%, with the significance of 0,001 (p<0,05). Further analysis for the aspects of teaching selfefficacy showed that magnitude aspect was increase for 26,73% (p<0,05) generality aspect was increase for 26,73% (p<0,05), and strength aspect was increase for 26,73% (p<0,05). In conclusion, field experience practice could significantly increase teaching selfefficacy of mathematics education students.

Abstract :Analysis of student responses in this study aims to determine the quality of Edmodobased learning media products that have been developed. The results obtained on average show 81% of this indicates a positive response from students. The most prominent of the six indicators used are happy and interesting. The statement of happy indicator that is learning with learning media based on Edmodo make student happy to reach 88%. While the interesting indicator states Edmodobased learning media is new in the lecture.

Abstract :The research aims to determine the enhancement of students mathematical thinking skills using the Model Eliciting Activities (MEA) approach and how students attitudes toward the Model Eliciting Activities (MEA) approach learning. The research method used quasi experiment with research design nonequivalent control group design. This research was conducted in SMP Negeri Cianjur with population in 7th grade. The sample used class VII4 as control class and class VII9 as experiment class. The instrument was essay question to measure mathematical creative thinking ability and a questionnaire of attitude scale as nontest instrument. The results showed that the enhancement of students mathematical creative thinking ability using the Model Eliciting Activities (MEA) approach was better than students using a scientific approach and most students attitude was positive response toward the Model Eliciting Activities (MEA) approach.

Abstract :The aim of this article is to describe the student’s error using Error Analysis (NEA) in Multivariable Calculus course. For analyzing the error, we analyzed the student’s finel test work. The analysis was held in two steps, qualitative and quantitative. Qualitative part was done when categorizing the error based on NEA, which are reading, comprehension,
transformation, process skill, and encoding. As the data triangulation, we also interviewed the students to con?rm the analysis results. From the analysis and interview, it was known that the errors were happened because the lack of basic algebra ability and the lack of ability of ?nding the function derivative.

Abstract :This research aims to increase the activity of mathematic by minimize the manner of mathematic difficulty on the submaterial of integers and multiplication. This research has done at SMPN 2 Pejagoan Kebumen and at SMPN 8 Purworejo. In the class 7A of SMPN 2 Pejagoan Kebumen there are forty students are given “the pair checking” learning model and in the class 7A of SMPN 8 Purworejo there are thirty students given “the pair searching” learning model. There is an improvement on the implementation of “the pair searching” learning model on the submaterial of multiplication to the class 7A student of SMPN 8 Purworejo in the academic year of 2011/2012, it is marked by the first result of observation of study activity in the ask’s braveness and the give a piece of mind to the first cycle is twelve students and after the implementation of “the pair searching” learning model is twentytwo students. The result of motivation and farvor to follow of learning (to finish for the self assignment and active for doing assignment be given by teacher to the first cycle get eighteen students and the second cycle get twentyfive students. The student interaction in follow the learning activity of group for the first cycle get twelve students and the second cycle twentyfive students. The student’s relationship with the teacher during the process learning (in the team work) to the first cycle get twentytwo students and the second cycle get twntyfive students and the student participation during the learning process get twentyfive students and the second cycle get twentyeight students. This is supported by result of satisfaction’s average 77,66 at the score distance very well, where as the first cycle get average 60,17 at the less score distance. From the result of the class measure research could be conclude that pair cheks learning model could be increase the student activity for the student seven A grade class SMPN 2 Pejagoan at the integer subject from the result get twentythree students at the early learning become twentynine students at the first cycle and thirtyfive students at the second cycle. The increase of the result study from 51,13 at the early learning become 61,33 the first cycle and the second cycle could be increase become 75,48 with the completeness 82,50.

Abstract :The aim of this research is to analyze predator prey population model with constant rate of harvesting which is called The Lotka Volterra model of predatorprey and to determine the stability from equilibrium points. This research used literature study, it means that the resources for creating this research are taken, collected, and arranged from various existed research result and books. The procedural steps in this research namely looking for the equilibrium from each equation then analyzing the behavior of equilibrium points obtained. In this research, pre and predator population model was analyzed, that has equilibrium point , and . The equilibrium of predatorprey and was reached in equilibrium point . The constant rate of harvesting in predatorprey population caused the equilibrium point had been changed, that was for obtaining the equilibrium point x by finding the roots of polynomial and for equilibrium point y is obtained by substitution x value that found to .
