        abstract = {Berdasarkan pengalaman praktik lapangan di Sekolah Menengah Pertama (SMP),
masih banyak siswa yang menganggap fisika merupakan mata pelajaran yang sulit
karena banyak menggunakan rumus matematis dan banyak pengembangan
konsepnya. Hal ini dikarenakan kemampuan mereka dalam mengoperasikan
rumus fisika secara matematika masih kurang. Apalagi pada materi gerak, siswa
harus bisa mengoperasikan rumus matematika, sebab terdapat beberapa hubungan
dan formulasi matematika dalam penguasaan konsep gerak. Salah satu upaya
yang dapat membantu siswa dalam meningkatkan penguasaan konsep khususnya
pada materi gerak adalah menumbuhkan skill representasi matematika mereka.
Berdasarkan hal tersebut, peneliti mencoba melakukan penelitian untuk
mengetahui pengaruh skill representasi matematika terhadap penguasaan konsep
gerak siswa SMP.
Penelitian ini bertujuan untuk: (1)Mendeskripsikan pengaruh skill representasi
matematika terhadap penguasaan konsep gerak siswa SMP, dan (2)Mengetahui
peningkatan penguasaan konsep gerak siswa SMP dengan menggunakan skill
representasi matematika.

Penelitian ini dilakukan di SMP Negeri 1 Pringsewu, menggunakan satu kelas
yaitu kelas VII5 dengan jumlah sampel 38 siswa dan menggunakan desain One-
Group Pretest ? Posttest. Pada penelitian ini diperoleh data skill representasi
matematika, data pretest dan posttest penguasaan konsep siswa yang berdistribusi
normal dan linier. Kemudian untuk menguji pengaruh dilakukan uji linearitas,
korelasi, dan regresi linear sederhana antara data skill representasi matematika dan
data posttest penguasaan konsep. Sedangkan untuk mengetahui peningkatan
penguasaan konsep dilakukan perhitungan persentase kenaikan skor, N-gain, dan
uji paired samples t test dari data pretest dan posttest penguasaan konsep siswa.

Hasil penelitian ini menunjukkan bahwa: (1)Terdapat pengaruh linear yang
positif dan signifikan antara skill representasi matematika terhadap penguasaan
konsep gerak siswa SMP dengan kontribusi sebesar 67\% dan persamaan
regresinya adalah Y? = 7,818 + 1,288 X, dan (2)Terjadi peningkatan yang
signifikan dari penguasaan konsep gerak siswa SMP dengan menggunakan skill
representasi matematika, dengan nilai N-gain rata-rata 0,58 yang termasuk dalam
kategori sedang.


Based on practical experience in the field of secondary school (junior high
school), there are still many students who think physics is a subject that is difficult
because many uses mathematical formulas and a lot of concept development. This
is due to their ability to operate in mathematical physics formula is still lacking.
Moreover, the motion of matter, students should be able to operate a mathematical
formula, because there are some relationships and mathematical formulations in
the mastery of the concept of motion. One effort that can assist students in
improving mastery of concepts, especially on the motion of matter is to develop
representations of their mathematical skills. Based on this, researchers are trying
to do research to determine the effect of the representation of mathematical skills
to junior high school students' mastery of the concept of motion.
This study aimed to: (1) Knowing the mathematical representation of the
influence of skill on students' mastery of the concept of junior high school
movement, and (2) Determine the increase mastery of the concept of motion
junior high school students using mathematical representation skills.

The research was conducted in SMP Negeri 1 Pringsewu, using a single class ie
class VII a sample of 38 students and design using the One-Group Pretest -
posttest. In this study obtained data representation of mathematical skills, pretest
and posttest data students' mastery of the concept of a normal distribution and
linear. Then to test the influence of tested linearity, correlation, and simple linear
regression between the data representation of mathematical skill and concept
mastery posttest data. As for knowing increasing mastery of the concept of
percentage increase in score calculation, the N-gain, and the test of paired samples
t test of pretest and posttest data student mastery of concepts.

The results of this study indicate that: (1) There is a positive linear influence and
significant relationship between the representation of mathematical skills to junior
high students 'mastery of the concept of motion with a contribution of 67\% and
the regression equation is Y' = 7,818 + 1,288 X, and (2) Occurs significant
improvement of students' mastery of the concept of motion SMP by using
mathematical representation skills, with the value of N-gain an average of 0,58 is
included in the category of being.}
