This research aims to analyze effectiveness of ethnomathematics with Solotigo Batik Motifs in Problem Based Learning model. This true experimental research desin used cluster random sampling to take the sample. The sample was taken from SD N Siderejo Lor 07, Salatiga, as experimental class and SD N Sidorejo Lor 03 Salatia as control group consisted of 74 students. The data collecting techniques were observation, documentation, and test. The data was analyzed by One Sample T - Test, proportion test, and Independent Sample t-test. The findings showed that ethnomatematics with Salatiga batik motifs in problem based learning model was effective. It was shown by (1) the average ethnomatematics with Salatiga batik motifs in PBL model was higher than 75.0. (2) the proportion of passing grade by using ethnomatematics with Salatiga batik motifs in PBL model could achieve classical passing grade, 75%. (3) The average of ethnomatematics with the batik motifs in PBL was higher than PBL model. (4) the average of variance by using ethnomatematics with Salatiga batik motifs in PBL was higher than PBL model. It could be concluded that ethnomatematics with Salatiga batik motifs in PBL model was effective. © Published under licence by IOP Publishing Ltd.
