ABSTRACT
The aim of design and building Fisikandroid application is presenting an education
application based on mobile android that contains physics formulas with more attractive
material so it will easy to be understood by students. Trial application respondent is students
of SMA N 2 Sukoharjo. Methods of data collection are questionnaire and comparison of
pretest result. The end result of this research is an educational application based on mobile
android that contains the physics formulas of class X, which presented more attractive and
easy to be understood by students. It is proved from the questionnaire that 86.67% of
respondents agreed if this application has elements of education, 96% of respondents stated
this is an attractive application, 82.67% respondents agreed the information in this application
is easy to understand, and 86.67% of students experienced increases in value after using this
application which means that this application can improve students understanding of the
material presented.
