CHAPTER 1
INTRODUCTION
1.1.Research Background
Education is one of the necessities of life that are very important to increase students quality. The education that is able to encourage the building in future is the education that is able to develop student’s potential, so students can be able to solve the life’s problem that faced. It is fundamental to remember that education is made as one measure of human welfare and education is seen as an effective tool in trying to preserve and inherit the values of life.
The developments in science and technology has prompted reform efforts in utilizing the results of technology especially in education. One of the problem that faced by education world is the problem of lack of learning, children are less encouraged to develop the ability to think. The learning process in the classroom geared to the child's ability to memorize information without required to understand the information that he remembered it to connect with everyday life. Consequently, when our students leave school, they are clever in theory, but they are poor in applications.

The quality of education can be achieved with a suitable learning process in the classroom. However, there are still many facts on the ground that student management systems only be done by direct instruction methods that can not make students enough understand and lead to passive students which can not foster and promote creativity and student learning outcomes. This is obvious with the discovery of the facts on the ground in SMAN 1 Padangsidimpuan that the students are still low in chemistry learning outcomes. It can be seen from the results of daily exams with the KKM value of Chemistry is 70, while the students that were able to achieve only 30%.
It is caused by the characteristic of Chemistry. Situmorang (2009) states that chemistry has difficult things to be learned because of its characteristics, they are: 1) a number of chemistry is abstract, 2) chemistry was implication from the fact, 3) chemistry are successive and develop quickly, 4) chemistry are not only about the explanation of facts, laws, term and etc, but also the numeric problem that has important part in learning chemistry, and 5) there are so many topics in chemistry that must be studied. Furthermore, the topics in chemistry is belongs to 3 characteristics, they are the decomposition of concepts, mathematical calculations, and excecution of experiments. According to this characteristics of chemistry and its topics, we need a creative teacher that has proper model of teaching for each chemistry’s topics.
The lack of student’s learning outcomes can not be separated from the quality of teacher performance in teaching and learning process in the classroom, where the teacher is an element in the process of teaching and learning that has important role in the success of students receive lessons and master optimally. The barriers in learning chemistry is where students are not comfortable the teacher’s way in learning process because it just uses a speech method of making a boring lecture for the student to absorb the lessons without understanding it well.
see the relevance that they often miss in other contexts. The promise of Problem Based Learning model is that students would learn better, understand what they learned, and remember longer by working cooperatively in groups. It prepares students to think critically and work creatively in using appropriate learning resources.
While salt hydrolysis is one of chemistry topic in senior high school for the second grade or class XI. On the topic of Salt Hydrolysis, there are 2 characters that must be mastered namely, 1) mastery of the concept of hydrolysis and the characteristic of salt solution, and 2) the claculation of the salt solution’s pH. Because of that, for mastery salt hydrolysis, we should apply the model of Problem Based Learning.
The Laws of Number 20 Year 2003 about The National Education System in paragraph 3 states that the national education has function to develop the ability and form the character and the culture of nation that has value in educating nation’s life. The national education has objective to develop the potential of students to be the faithful human to the God, have a certain character, healthy, bookish, capable, creative, autonomous, and being the democtratic and responsibility citizen (Deputi Menteri Sekretaris Negara Bidang Perundangundangan, 2003).
Based on the function and objective of national education, Suyanto (2009) states that education in every level must be under one’s belt systematically to reach the objective. It relates with the character formation of students to be able competing, have ethics, moral and respectful with interacting people. It shows that the quality of student’s character education is very important to be improved.

subject not as object in learning process, and arranging the exact evaluation until they can support the creativity development of students (Fatimah, 2009).
Because of the reason, the writer wants to apply the learning model that can improve student creativity by using some media such as macromedia flash animation, power point presentation and etc. This is the suitable media for showing the visualization of the material so there is no misundersatanding between students and teacher. It shows the interesting illustration for students from the animation so student can be more active and creative in learning the topic. By using some media and Problem Based Learning model, students can more comprehend the material of Salt Hydrolysis well so it can improve the learning outcomes and the creativity of the students. Sinaga (2012) has done the research and state that the problem based learning with macromedia flash animation is better than the direct instruction method with macromedia flash animation on the topic acid and base. Then the research of Belliyna (2010) conclude that PBL give significant in learning outcomes of SMP Bridjen Katamso Medan students in chemistry on the topic acid and base as 30.69 %. The research of Raja (2013) also concluded that the effectiveness of Problem Based Learning (PBL) that integrated by multimedia based on computer is 11.56% in rate reaction topic.
Based on the background mentioned above, the writer has done the research which title is: “The Implementation of Problem Based Learning with Multimedia Based on Computer to Foster The Student’s Creativity and Increase The Student’s Achievement in Salt Hydrolysis Topic.”
