摘要：Tujuan penelitian ini untuk mengetahui model pembelajaran Problem Based Learning (PBL) bernuansa etnomatematika efektif terhadap kemampuan pemecahan masalah siswa.Populasi dalam penelitian ini adalah siswa pada kelas VIII SMP N 1 Demak tahun pelajaran 2014/2015.Pengambilan sampel menggunakan cluster random sampling.Pengumpulan data dilakukan dengan metode dokumentasi,observasi,angket,dan tes.Analisis data menggunakan uji One Sample T Test,uji proporsi,uji Independent Samples T Test dan uji regresi linear berganda.Hasil Penelitian menunjukkan bahwa (1) kemampuan pemecahan masalah siswa yang memperoleh pembelajaran model PBL bernuansa etnomatematika mencapai KKM,(2) kemampuan pemecahan masalah siswa yang memperoleh pembelajaran model PBL mencapai KKM (3) kemampuan pemecahan masalah siswa yang memperoleh pembelajaran model PBL bernuansa etnomatematika lebih tinggi daripada kemampuan pemecahan masalah siswa dengan model PBL,(4) terdapat perbedaan sikap terhadap budaya lokal antara sebelum dan setelah diterapkan pembelajaran model PBL bernuansa etnomatematika dan (5) aktivitas belajar siswa dan sikap terhadap budaya lokal siswa berpengaruh terhadap kemampuan pemecahan masalah siswa,sehingga dapat disimpulkan model pembelajaran PBL bernuansa etnomatematika efektif terhadap kemampuan pemecahan masalah siswa kelas VIII.
其他摘要：The purpose of this study to determine Problem Based Learning (PBL) model with ethnomathematics nuances is effective toward student’s problem sloving ability.The population of this study are students of VIII grade in SMP N 1 Demak in academic year 2014/2015.Sampling using cluster random sampling.Collecting data with the method of documentation,observation,questionnaires,and testing.Analysis of the test data using One Samples T Test,Independent Samples T Test and regression test.The result of this study showed that (1) problem solving ability of the students who are given PBL model with ethnomathematics nuances is completeness study,(2) problem solving ability of the students who are given PBL model is completeness study,(3) problem solving ability of the students who are given PBL model with ethnomathematics nuances is higher than the problem solving ability of the students with PBL model,(4) there are differences in attitudes toward local cultures between before anda after the implementation of the PBL model with ethnomathematics nuances,and (5) the student’s learning activities and attitudes towards local cultures affect the student’s problem solving ability,so it was concluded that determine PBL model with ethnomathematics nuances is effective toward student’s problem solving ability grade VIII.
