Therefore, teachers need to diagnose students' learning difficulties in order to overcome these difficulties. The purpose of this research is to 1) describe students’ difficulties in solving word problem related to the quadratic inequalities; 2) diagnose the cause of these student difficulties. This study is descriptive-qualitative research design. In this case, the researcher is the primary instrument. In collecting the data, the researcher used a diagnostic test sheet, interview and field notes. In this study, triangulation of data source is applied to check the validity of the data. Result of diagnostic test shows that student difficulties are: (a) not identify the problem, (b) not written the information into mathematical model, (c) did not know/forgot the concept of word problem that is GLBB and total revenue, (d) have not been able to make quadratic inequalities, and e) have not been able to determine its solution set. Diagnosis in this research using mapping mathematics, that is a diagram that arrange based on student difficulties.
