Algebra is an important part of Mathematics that Grade 7 students must learn. Students have difficulty learning algebraic concepts at ABC School in Lampung. The purpose of this study is to identify the difficulties experienced by students in learning algebraic conceptss as well as identify factors that affect students who experience difficulties. This research uses a qualitative case study approach focusing on two students in class VII. Data collection techniques consisted of tests, planned unstructured interviews, and student task documentation. The results showed that: (1) students' difficulties in learning mathematics related to the concept were: (a) difficulty in identifying concepts; (b) difficulty using symbols to represent concepts; (c) difficulty in identifying the given conceptual properties and recognizing the conditions specified by a concept; (d) difficulty translating from a presentation model to another presentation mode; (e) difficulty comparing and asserting concepts; and (2) Factors that make it difficult for students are the influence of difficulty on a particular topic and difficulty in abstracting.BAHASA INDONESIA ABSTRAK: Aljabar adalah salah satu bagian penting yang harus dipelajari oleh siswa.
