This research uses descriptive qualitative method. The subjects of this study were class IXB SMP Negeri 1 Tumpaan. The data collection techniques in this study used test questions, interviews, and documentation. The data analysis technique in this study used the Miles and Huberman models, including data reduction, data testing, and inference. The results showed that the average percentage of difficulty students had in solving physical problems with static electricity material according to Polya's Problem Solving Levels: (1) Problem phase understanding was 76.66%. The reason for this is that the students forget and do not understand the meaning of the questions. (2) The planning phase for problem solving is 78.66%. The reason is that students don't know which equation to use. (3) Phase of implementation of problem-solving planning of 84.66%. The reason for this is that students don't know which equation to use. This results in the students having difficulty in the implementation phase of the plan and less able to do calculations. (4) The review phase is 90%. The reason is that the students are not thorough and do not double-check their answers.

The use of learning models and approaches is important in the learning process. Physics learning needs to apply a learning model so that students can be actively involved in learning. Then they can construct their own knowledge that they learn through the investigation process. The guided inquiry model with the JAS approach is a learning model that can open up diverse thinking insights so that students can learn various concepts and how to relate them to natural phenomena. This study aims to determine the influence of the guided inquiry model with the JAS approach on learning outcomes and the learning environment on students' self-confidence in responding to learning. The method used in this research is experimental with the research design employed, namely, single group pretest-posttest (the one group, pretest-posttest design). The average score of learning outcomes using the guided inquiry model with the JAS approach (outside the classroom) was 74.14, and the average learning outcome using the guided inquiry model (inside the classroom) was 49.75. The results showed that the use of the JAS approach was very influential in understanding the concept of physics.
