Abstract

Many students find it difficult to understand the concept of algebra because it is abstract, so it is necessary that the abstract method of algebra become more concrete, one of the methods that can be used is Al-Khawarizmi method. This Research is intended to analyze students’ mistakes in working out factoring using Al-Khawarizmi, so that the mistakes can be minimized in the future. This research is a qualitative research with sampling through purposive sampling technique. The study was held in SMP (Junior High School) Negeri 2 Cileunyi. The subjects were 32 students of class IX. The main data was from the results of the factoring test by Al-Khawarizmi. Data analysis was carried out through reduction, presentation data, and withdrawal. This study describes the student’s mistakes in working out the factoring using Al-Khawarizmi method which includes counting error, visualization of equation, algorithm, measurement of answers, and student’s accuracy. From the result of research done by student in mathematical operation equal to 15.38 %, percentage of error in visualization equation 21.54 %, error in algorithm 4.62%, student error in answer is 29.23 %, and student error in accuracy is 29.23 %. This indicates that the error in the level of language is significant. As a whole this method is effective to use.
