Based on the problems faced by partners, the purpose of the CommunityPartnership Program (PKM) activity is to provide training and mentoring for members of the MGMP Mathematics VocationalSchool Majene in using the GeoGebra application so that it can be used as a medium for learning mathematics. Phase I of thePKM implementation begins with the coordination and analysis of needs. Phase II preparation and validation of the GeoGebramodule. Phase III conducted a workshop on the application of GeoGebra on geometry and linear programs. Phase IV providesassistance to MGMP on the application of GeoGebra in the classroom. The instruments used in PKM activities consisted of two,namely (1) pretest and posttest in the form of performance tests and (2) questionnaires before and after PKM training andmentoring. The results of the analysis of the pretest, obtained an average value of MGMP performance tests in using theGeoGebra application that is equal to 56.17, while the average posttest value is 97.25.
