One of the elements in the implementation of Higher Education is a lecturer. Lecturers are academic staff who are tasked with carrying out the Tri Dharma of Higher Education which includes education, research, community service. Lecturers who excel are entitled to be selected and get promotions and awards according to their academic performance. Therefore, we need a calculation method that can be used as a media for performance appraisal of outstanding lecturers who can facilitate assessment. This assessment includes performance appraisal which includes commitment, integrity, service orientation, discipline, cooperation, and leadership. In addition to the criteria, the assessment also includes the Employee Performance Target (SKP) assessment. This Employee Performance Target is in the form of a total assessment of lecturer performance. Two criteria, namely performance and SKP will be used as guidelines in the calculation of the selection of outstanding lecturers. Samples were taken as many as 20 lecturers at the Sriwijaya State Buddhist College in Tangerang. The simple additive weighting method is effectively used in the selection of outstanding lecturers with an assessment limit of more than 0.88. Of the many candidates, there were three lecturers with sufficient performance and SKP, with grades 0.922, 0.88, 0.94. So that the highest achieving lecturer with the highest value is 0.94.

Learning style is an activity of thinking, processing, and understanding something that is preferred and has the characteristics of each person. Problem-solving ability is a skill that needs to be possessed in the process of solving mathematical problems. This study aims to describe students' problem-solving abilities on social arithmetic material in terms of learning styles. The research was conducted through a descriptive qualitative research design. The population is all seventh-grade students of MTs Al-Khairiyah, South Jakarta. Sampling using a total sampling technique. Then three students were selected, namely students who scored the highest visual, auditory and kinesthetic learning styles. The instrument uses a learning style questionnaire and a test of problem-solving skills and semi-structured interviews—data analysis techniques with data reduction, exposure, and concluding to explain mathematical problem-solving abilities. The findings of this study are students with the highest scores of visual, auditory, and kinesthetic learning styles can solve social arithmetic problems based on Polya's steps without any significant differences, only from different styles when solving problems
