ABSTRAK
Tujuan penelitian ini adalah: (1) Untuk mendeskripsikan penerapan langkah-langkah pendekatan Saintifik  dengan media konkret, (2) mendeskripsikan peningkatan  pembelajaran Matematikatentang operasi penjumlahan dan pengurangan pecahan melalui penerapan pendekatan Saintifik dengan media konkret pada siswa kelas V SD Negeri Srusuhjurutengah Tahun Ajaran 2014/2015 dan (3) mendeskripsikan kendala dan solusinya.
Penelitian ini merupakan penelitian tindakan kelas kolaboratif dengan tiga siklus.Tiap siklus terdiri atas perencanaan, pelaksanaan tindakan, observasi, dan refleksi.Subjek penelitian adalah siswa kelas V SD Negeri Srusuhjurutengah berjumlah 23 siswa.Data berasal dari siswa, guru, observer, dan dokumen.Teknik pengumpulan data adalah dengan tes hasil belajar, observasi, pedoman wawancara, dan dokumentasi.Validitas data menggunakan teknik triangulasi sumber dan triangulasi teknik pengumpulan data. Analisis data menggunakan teknik analisis data kuantitatif dan kualitatif, meliputi: reduksi data, penyajian data, dan penarikan kesimpulan atau verifikasi.
Hasil penelitian menunjukkan bahwa: (1) langkah pendekatan Saintifik dengan media konkret yaitu: (a) mengamati, (b) menanya (c) mencoba/mengumpulkan informasi, (d) menalar/mengolah informasi, (e) mengkomunikasikan, (2) penerapan pendekatan Saintifik dengan media konkret dapat meningkatkan pembelajaran Matematika tentang operasi penjumlahan dan pengurangan pecahan pada siswa kelas V SD Negeri Srusuhjurutengah tahun ajaran 2014/2015 terbukti dari persentase ketuntasan siswa pada siklus I = 86,96%, siklus II = 91,30%, dan pada siklus III = 91,30%, dan (3) kendala yang ditemui dalam pelaksanaan pembelajaran yaitu: (a) Guru kurang menyiapkan siswa, (b) Guru kurang memberi motivasi, (c) Guru kurang memberikan bimbingan, (d) Guru belum menjelaskan materi secara keseluruhan, (e) Guru belum menyiapkan lingkungan belajar dengan baik. Solusi untuk mengatasi kendala tersebut yaitu: (a) Guru seharusnya memerhatikan kondisi siswa di dalam kelas untuk mengikuti pembelajaran, (b) Guru harus lebih memerhatikan apa yang dilakukan siswa kegiatan diskusi, (c) Guru bisa memberikan bimbingan agar siswa tidak malu, (d) Guru seharusnya menjelaskan materi kepada siswa secara keseluruhan, (e) Guru seharusnya menyiapkan lingkungan belajar.
Simpulan penelitian ini adalah penerapan pendekatan Saintifik dengan media konkret dapat meningkatkan pembelajaran Matematika tentang operasi penjumlahan dan pengurangan pada siswa kelas V SD Negeri Srusuhjurutengah tahun ajaran 2014/2015.

ABSTRACT
The objectives of this research are: (1) to describe steps of the application of scientific approach using concrete object media, (2) to describe an increase in mathematics learning about operations of addition and subtraction of fractions through the application of scientific approach using concrete media in for the fifth grade students of SD Negeri Srusuhjurutengah in the academic year of 2014/2015 and (3) to describe problems and solutions.
This research is a collaborative Classroom Action Research (CAR) conducted in three cycle. Each cycle consisted of planning, implementation, observation, and reflection. The subjects of this research were 23 students of SD Negeri Srusuhjurutengah in the academic year of 2014/2015. The sources of data were obtained from students, teachers, observers, and document. The data collection technique used test of learning outcomes, observation, interview, and documentation. The validity of the data used triangulation techniques of sources and triangulation techniques of data collection. The techniques of analyzing data were quantitative and qualitative techniques, consisting of data reduction, data display, drawing conclusion or verification.
The results of the research show that: (1) the steps in the application of scientific approach using concrete object media, namely: (a) observing, (b) questioning, (c) experimenting, (d) associating, (e) communicating; (2) the application of the scientific approach using concrete object media can improve Mathematics learning about operations of addition and subtraction of fractions for the fifth grade students of SD N Srusuhjurutengah in the academic year of 2014/2015. It was proven by the evidence from the percentage of completeness of students in the first cycle was 86.96%, in the second cycle was 91.30%, and in the third cycle was 91.30%, and (3) Problems in the implementation of learning were: (a) teachers are less prepared students, (b) the teacher lack in motivating students, (c) the teacher lack in giving guidance, (d) the teacher did not describe the whole materials, (e) the teacher did not provide a good learning environment. Solutions to overcome these problems, namely: (a) the teacher should pay attention to the condition of the students in the classroom, (b) the teacher should be more attention to students while discussions, (c) the teacher can give guidance so that students are not shy, (d) the teacher should explain material to students as a whole, and (e) the teacher should prepare the learning environment.
The conclusion of this research is the application of scientific approach using concrete object media can improve Mathematics learning about operations of addition and subtraction of fractions for the fifth grade students of SD Negeri Srusuhjurutengah in the academic year of 2014/2015.
