Every student has a different memory, depending on how the student responds to stimuli. Memory is very important in the learning process, because it is directly related to the material being taught, and the part of the body that plays a very important role is the brain. Memory plays a very important role because during exams, students must be able to process their memory to get good grades. Thus, the problem of memory must be overcome by using effective learning to encourage student memory to be optimized as best as possible. Optimal use of the brain in learning can use the BBL model assisted by mind mapping. Where the BBL learning model aims to develop five natural brain learning systems that can develop the brain's potential to the maximum and mind mapping is a creative way for students to record lessons and generate ideas. The resulting ideas will be expressed in the form of a mind map allowing students to remember the material more easily. This research aims to determine the effect of implementing the BBL learning model assisted by mind mapping on students' memory based on gender. This research uses a quantitative approach with a quasi-experimental method with a one group pretest posttest design. Sample selection was carried out using purposive sampling technique. The results of the T-Test for Equality of Means show a Sig value. < 0.05 which is 0.00. Thus it can be said that female students have stronger memories than male students.
