This type of research used in this research is descriptive qualitative research. Subjects in the study were eight students from Class XI MIPA 1 SMA Negeri 7 Kediri consisting of two students from each of the guardian, artisan, idealist, and rational personality type. The data collection methods used were questionnaires, tests, and interviews. The instruments used in this study were MBTI questionnaires, shape and space content PISA test questions, and interview guidelines. The results showed that the achievement of the characteristics of the eight spatial-visual abilities of the subjects differed. Students with guardian personality are able to fulfill two characteristics of visual-spatial intelligence consisting of pattern search and conceptualization, but unable to fulfill the characteristics of problem-solving and imagining. Students with artisal personality are able to fulfill two characteristics of visual-spatial intelligence which consist of pattern searching and imagining. Students with idealist personality are able to fulfill the three characteristics of visual spatial intelligence which consist of pattern searching, conceptualizing, and imagining. Students with rational personality are able to fulfill all the characteristics of visual abilities consisting of pattern search, conceptualization, problem solving, and complete imagination in solving shape and space content PISA questions. This can be seen from the results of solving the questions given and interviews conducted on the research subjects.

Abstract This research raises the problem of students' problem solving abilities in solving arithmetic sequence and series problems based on the theory of APOS (Action, Process, Object, Schema) in terms of the type of Florence littauer personality. Data collection was obtained from personality type questionnaires, problem solving tests, and interviews. The subject of the study came from 4 students of class XI TKJ 1 of SMK Negeri 2 jember using the snowball sampling method to classify 4 personality types which include sanguinis, koleris, melancholy, and phlegmatic. The results of the analysis of problem solving ability tests and interviews showed that at the stage of action, sanguinis (SS) students could explain smoothly and complete the lack of data on the answer sheet. Koleris students (SK), explained fluently and consistently, melancholy students (SM) could explain correctly even though in answering questions they were still hesitant. Phlegmatic students (SP) are fluent and assertive when explaining the information in the question again. At the process stage, students of SS, SK, SM, and SK managed to find a number pattern and could determine the formula to solve the problem. At the object stage, the four subjects managed to answer correctly even though they used different problem solving processes. At the scheme stage, SS students, SK, SP managed to give the final answer correctly and tried to check the answer again, while the SM students had not managed to answer correctly.
