ABSTRAK
Tujuan penelitian ini adalah untuk meningkatkan hasil belajar matematika
materi bangun ruang melalui model Problem Based Learning pada siswa kelas V SD
Negeri 3 Kiringan Tahun Ajaran 2011/2012.
Bentuk penelitian ini adalah penelitian tindakan kelas, yang terdiri dari dua
siklus. Tiap siklus terdiri dari empat tahap yaitu perencanaan, pelaksanaan,
observasi, dan refleksi. Teknik pengumpulan data menggunakan metode observasi,
tes, dokumentasi, dan wawancara. Validitas data menggunakan teknik triangulasi
sumber, metode, penyidik, dan teori serta validitas isi. Indikator kinerja yang
ditetapkan yaitu pada akhir siklus siswa mencapai KKM (nilai 70) sebesar 80% dari
jumlah siswa kelas V. Teknis analisis data menggunakan analisis deskriptif
komparatis dan kritis.
Hasil penelitian diperoleh kesimpulan model Problem Based Learning (PBL)
dapat meningkatkan hasil belajar matematika pada siswa kelas V SD Negeri 3
Kiringan Kecamatan Boyolali Kabupaten Boyolali Tahun 2011/2012. Hal ini
ditunjukkan dengan hasil belajar siswa pada kondisi awal, nilai tertinggi 78 dan
terendah 50, siswa mencapai KKM sebanyak 6 siswa (31,58%) dengan rerata sebesar
63,11. Pada siklus I hasil belajar siswa yaitu nilai tertinggi 80 dan terendah 60, siswa
mencapai KKM sebanyak 14 siswa (72,68%) dengan rerata 70,42. Pada siklus II
hasil belajar siswa yaitu nilai tertinggi 85 dan nilai terendah 70, siswa yang mencapai
KKM sebanyak 19 siswa (100%) dengan rerata 76,32.

ABSTRACT
The objective of this research is to improve the learning result in
Mathematics on the topic of discussion of Geometry through the Problem-Based
Learning of the Students in Grade V of State Primary School 3 of Kiringan in
Academic Year 2011/2012.
This research used the class action research (CAR) method with two cycles.
Each cycle consisted of four steps, namely: planning, implementation, observation,
and reflection. The data of research were collected through observation, test, and indepth
interview. They were validated by using the data source triangulation, method
triangulation, theory, and content validity, investigator, theory, and content validity.
The performance indicator set in final cycle was at least 80% of students could
accomplish the minimum learning completeness criterion score i.e. 70. The data of
research were analyzed by using the descriptive comparative and critical analysis.
The result of the research shows that Problem Based Learning (PBL) can
improve the learning result in Mathematics on the topic of discussion of Geometry
the students in Grade V of State Primary School 3 Kiringan in Academic Year
2011/2012. Prior to the treatment, the highest score was 78 and the lower score was
50, and the number of students who fulfilled the minimum learning completeness
score criterion was (6) 31.68% with the average score of 63.11. Following the
treatment, the highest score became 80 and the lower score became 60, and the
number of the students who fulfilled the minimum learning completeness score
criterion was 14 (72.68%) with the average score of 70.42 in Cycle I. In addition, the
highest score became 90 and the lower score became 70, and the number of the
students who fulfilled the minimum learning completeness score criterion was 19
students (100%) with the average score of 76.32 in Cycle II.
