The purpose of this study is to analyze students' difficulties in solving the surface area problem of cones and tubes and the factors that cause them. The research subjects consisted of 32 seventh grade learners in a public junior high school in Tasikmalaya City. The research instruments included tests to identify learners' difficulties and in-depth interviews with some learners to gain further insight into the factors causing difficulties. The results showed that most of the students had difficulties in understanding the basic concepts of three-dimensional geometry, especially in applying the formula for the area of cones and pipes. Common difficulties found included an inability to recognize the elements of cones and tubes, difficulty substituting values in the formula, and obstacles in basic algebra that affect the final calculation results. Further analysis revealed that factors contributing to these difficulties included a lack of visualization skills and spatial understanding. Discussion of the results highlighted the importance of a more interactive and contextualized approach to learning, including the use of visual aids and manipulatives to help students visualize three-dimensional shapes and better understand the concept of surface area. The implications of this study include improving the curriculum and teaching strategies for mathematics at the junior secondary level, with a focus on developing learners' visualization skills and spatial understanding.

In mathematics learning at school, there are not many teaching materials that can support the learning process according to the needs of each student. One solution that can help students learn according to their needs is to use differentiated Student Worksheets (LKPD). The aim of this research is to produce a product in the form of a differentiated LKPD in terms of extrovert and introvert personalities using a project-based learning model on flat-sided building material for junior high school students. This type of research is Research and Development (RnD) with a 4D development model by Thiagarajan, which goes through 4 stages: Definition, Design, Development, and Dissemination. The subjects of this research were students in class VIII H of SMPN 5 Purwokerto. The instruments used are questionnaires to measure validity criteria and response questionnaires. The results of the research show that the differentiation LKPD in terms of extrovert and introvert personalities using a project-based learning model on flat-sided building material for junior high school students has met the very valid criteria with an average score of 3.63. Apart from that, this LKPD also received a very practical category with an average score of 3.13. These results indicate that this development product is suitable for use in the learning process.
