The mathematical problem solving skill is an effort to find solution of mathematical problem that is faced by students. In problem solving process, the students leadtheir entirecapability. The competencies which are used in problem solving namely rationality, creativity, and other thinking abilities. Problem solving needs conceptual understanding ability (conceptual knowledge), ability to do inter-conceptual relationship (principle and procedure), accuracy, and student’s mental readiness. Problem solving is an important aspect in learning mathematics. A student called mastering certain mathematics lesson if he/she has a problem solving skillwhich is contained in the lesson. Problem solving skill is necessary to be implemented to the student’s competency from the elementary school. Problem solving skill is need to be trained and be accustomed to the student as early as possible.It is significant because the students haveskill to solve mathematical problem when they have many experiences. The experience of mathematical problem solving will be provision for facing daily life problems. Problem solving skill relates to lessons in curriculum. It is in order to see how far the student’s skill in calculating, remembering, and applying mathematical formula relevantly. The results of mathematical problem solving ability of primary school students in the category which is equal to 56.50% of the 915 questions. Problems that can be completed correctly that as many as 517 questions that consists of 392 questions form Algebra, 93 about the form of Geometry, and Algebra 32 question form with the average time required for 51.1 minutes. In solving the problem, students will have a motivation to use continuously their knowledgeif the result that obtained is a solution from the problem they faced.

INTRODUCTION

            Mathematics in primary education has an important role in sustainable life because this level is the foundation of a very decisive in shaping attitudes, intelligence, knowledge, solve problems, and form a formidable personality of the child. Math lessons given mainly in basic education meant that at the end of each stage of education learners have certain abilities for the next life. The phenomenon of the field shows that the persistence of primary school students who have difficulty in dealing with problems in math, think math is not interesting, and boring. This complaint directly or indirectly will greatly affect the learning achievement of the observer while the other hand continues to strive to introduce educational and interesting mathematics. One of the interesting mathematical form of recognition that by hosting various competitions both at local, national, and international levels. Until in the end local and central government is very supportive by providing the highest appreciation for students who succeeded the name of the region and nation. Unmitigated lately the government through the Ministry of Education provides scholarships for continuing education kejenjang higher for students who earn a medal at the international level. This achievement is certainly very encouraging for him, his family, and also the name of the region.

Mathematics competitions held by each agency aims to improve analytical capabilities, creative, critical, problem solving abilities and hone the reasoning power of the students. In essence, the application of mathematical knowledge of the subject matter is not only in the classroom, but also applicable in various contexts of mathematics. It aims to look at the extent to which students are able to understand and master mathematics in school. It is also in line with that proposed by the Ministry of Education (2006) that the elementary school mathematics courses have the aim that students have the ability to: (a). Understand mathematical concepts, explains the relationship between concepts, and apply the concepts or algorithms flexibly, accurately and efficiently, and appropriately in solving the problem, (b). Using the pattern and nature of the reasoning, mathematical manipulation in making generalizations, compile evidence, or explain ideas and mathematical statements, (c). Solve problems that include the ability to understand the problem, devised a mathematical model, resolve and interpret the obtained solution, (d). communicate ideas with symbols, tables, diagrams, or other media to clarify the situation or problem; and (e). Having respect for the usefulness of mathematics in life, which has a curiosity, attention and interest in studying mathematics, as well as a tenacious attitude and confidence in solving problems.

Compitition mathematical carried apply the appropriate scope of the guidance material Depdiknas. Competition mathematics courses in the educational unit SD / MI in accordance with the covering aspects of numbers, geometry and measurement, and data processing (Depdiknas, 2006). Knowledge of students is always growth and perkembanagan relevant. The brain is able to mnyerap knowledge students according to age level. The development of new knowledge structures composed of prior knowledge. Developing knowledge structure based on the mental development of the individual student. growth characteristics of elementary school students have relevant developments with changes in the level and function of the characteristics of the age of the students. The knowledge of different grade 3 students with the knowledge possessed by students in grade 6. This According to Piaget (Dahar, 1991: 152) the stage of cognitive development of children include: first sensory-motor stage (ages 0-2 years) at this stage children set natural with the senses (sensory) and actions (motor), both pre-operational stage (2-7 years old) at this stage the level of intellectual development of students is divided into two namely sub-level pralogis (2-4 years) and the level of thinking intuitive (4-7 years), three concrete operational stage (ages 7-11 years) at the beginning of this stage is the stage of rational thinking, this means that the child already has a logical operations that can be applied to concrete problems, and the last operational phase Formal (ages 11 years and so on) at this stage the child can use concrete operations to establish operations more complex, this can be seen in children who are not bullet think with the help of objects because iniu diperode child has been able to think abstractly .

Based on the child's cognitive development theory proposed by Piaget, the students who participated in this competition are students concrete operational and formal operational stage. This is supported by research Driscoll (Suherman, et al 2003: 91) states that at the age of elementary school children to be intimately linked with problem solving skills. So with this stage students are able to use imagination, reasoning power and kretaifitasnya in solving the problem. In the implementation of this math competition also strived minimized using concrete objects or pictures. So the correct solution they found was the understanding and application of mathematical concepts discoveries that have experienced students.

According Hodojo (1988 ) and learning experience of a student will affect subsequent mathematics learning process. This means that students will be trained with basic knowledge questions, then understanding the concept earlier in elementary school will greatly affect the further mastery of the material at a higher level. One of the demands in learning mathematics for students in schools is the ability to solve mathematical problems. Solving math problems in school is seen as one alternative to find out that a student has been able to master a particular material. In the process of solving the problem of students directs segalah knowledge to be able to finish it. Begin of collecting facts, finishing with the concept, to draw conclusions. In an effort to solve the problems of the students towards mathematics needed tricks or methods that must be mastered and performed by each student. Trick or method performed based on the experience of students.

One of the objectives given in the math curriculum for students is that students have the ability to problem-solving. Mathematics then taught school for students that in order to have the knowledge, understanding, abilities, and skills in solving math problems or have the ability to solve the problems of mathematics. it is becoming important taught in school that the students have experience in troubleshooting. Similarly, according Dwiyoso (Purba, that the purpose of education in schools not only enhance the acquisition of knowledge, but should be able to develop problem solving skills. The so-called mathematical problem here is the mathematical problems that can not be directly answered by the student or direct proficiency level problems can be answered with routine procedures, but rather problems that are solved by using the method or certain tricks.

Problems in mathematics is not a problem whose solution only use is common knowledge in class. But the problem is presented requires the ability to find, megolah, collect, and dig information from around the problem. The issues presented are simple problems but requires enough knowledge to get the solution of the problem. According Hudoyo (1988: 122) that the problem situations presented to learners should be simple enough to be managed, yet complex enough to be resolved. Situation problem simple yet complex penyelesaianya takes control of the structure of the concept, the structure of the procedure, or surgery are used in solving the problem.

According Suherman, et al (2003: 92-93) that a problem usually includes a situation that encourages someone to finish it but do not know directly what to do to solve it. That is to address these problems requires a student experiences in resolving issues / problems of the non-routine. based on this opinion is also a problem and solving the problem of the unity of meaning said means requires students to have a desire to get it done.

Based on the opinions of the above it can be concluded that the issues or questions raised by others is a problem when the problem challenging or desire to finish with the completion of the use of tricks, methods, or procedures that are not normally (non-routine ).

Elementary students is basically an initial foundation to instill problem-solving abilities. The purpose of school students one of them in order to have the ability to solve problems encountered throughout his life. By him that students should be taught from an early age the ability to solve the problems encountered. Thus, students are able to think independently, creatively and critically. Problem solving skills students need skills. Good memorization skills, the ability to reason, creative, always sensitive to the problem.

Effort a student in order to have the ability in solving mathematical problems right that he should recognize, explore, and understand the problem clearly. A student is able to recognize the basic overview of the problems encountered. By making it the problem will be felt easily. In recognizing the problem, determine the length of time it takes to solve different, there is a fast finish, there also took a long time to complete. This difference depends on the extent to which the student is able to recognize the information in the problem. Also depends on the familiarity of students to the problem. rapid students in completing the problem means that students have had good experience with problem solving.

According Hudoyo (2003: 91) that the mathematical problem solving ability of students to be tailored to the child's level of ability. In applying problem solving skills required of a student's thought process. The thought process is defined as the process of generating a new mental representation through the transformation of information that involve complex interactions only between mental attributes such as assessment, abstraction, reasoning, imagination, and problem solving (Glass and Holyoank, 1986; Solso, 1988). In applying the guidance of the troubleshooting process will make the process of thought to represent the cognitive abilities such as memory, understand, apply, analyze, evaluate, and create. According to psychologists learning Anderson & Krahwohl (2010: 99) in order to determine the category in the dimension of the cognitive process the teacher can provide the questions. The categories and cognitive processes (Anderson & Krahwohl 2010: 100-102) are as follows:

1.      Given: take the knowledge of the long-term

a. Recognize

b. Recalling

Cognitive processes: Students will declare the results of operations mixture of single-digit numbers

Example question: What is the result of (-2) x (-5) + 2?

2.   Understanding: constructing knowledge of instructional materials, including what is spoken, written, and drawn by the teacher.

a. Interpret

b. Exemplifying

c. Classify

d. Embrace

e. Conclude

f. Compare

g. Explain

Cognitive processes: Students will interpret the results of the cube root of a number
Example question: Determine ?

3.   Apply: apply or use a procedure in certain circumstances.

a. Execute

b. Implements

Cognitive processes: Students will use a non-routine procedures

Example question: Given the number of different two numbers is 15 and the difference between the two numbers is 3. Determine the numbers?

4.   Analyze: breaking down the material so its constituent parts and determine the relationships between the parts and the relationships between the parts and the overall structure or purpose.

a. Distinguish

b. Organize

c. Attribute

Cognitive processes: Students will distinguish the factors primes

Example question: Determine the number of prime factors of 360 and 900?

5.   Evaluate: make decisions based on the criteria and / or standards.

a. Check Up

b. Criticize

Cognitive processes: Students will describe and compare the standard algorithm

Example question: In the world of fairy tales days used only 5 ie, Monday, Wednesday, Friday, Saturday, and Sunday. If today is Wednesday, the fairytale world in which to-day is 378?

6. Creating: Integrating the parts to create something new and coherent or to make an original product

a. Formulate
