Abstract

This study was motivated by the low understanding of students in learning mathematics on the limit material of algebraic functions. The learning process that occurs is less effective with the existence of students who have low absorption of learning materials. To overcome the low student understanding of the limit material of algebraic functions, a problem-based learning model with peer teaching was applied. The type of research used is classroom action research (PTK) using 2 cycles, each cycle consisting of 1 meeting. The research stages consist of planning (palnning), action (action), observation (observation), and reflection (reflection). The results of the research that has been done, it can be concluded that, the application of problem-based learning model with peer teaching method to improve the understanding of the limit of algebraic function in class XI MIPA 1 SMA Negeri 1 Sobang. This is evidenced by the acquisition of increased student understanding through learning outcomes in the form of written test assessment results. The acquisition of an increase from cycle 1 meeting 1 from 51.35% to 70.05% cycle 1 meeting 2. Cycle 2 meeting 1 from 70.05% to 84.65% in cycle 2 meeting 2.

Abstract

This study aims to examine the effect of Service Quality on Customer Satisfaction with the mediation of Management Performance in a transportation service company (Gojek). The research problem addressed is whether service quality has a direct and indirect effect on customer satisfaction, and how the role of quality management contributes to this relationship. Since the population is considered infinite, the sample size was determined using Lemeshow's formula, resulting in 96 respondents. This study uses a quantitative approach with mediation regression analysis based on the method proposed by F. Hayes, involving active users of Gojek services as respondents. The results show that Service Quality significantly influences Customer Satisfaction, both directly and through the mediation of Quality Management Performance. The indirect effect value of 0.5209 with a confidence interval of [0.3889–0.6733] confirms the significance of the mediation. These findings indicate that improving service quality must be supported by an effective management system in order to have a maximal impact on customer satisfaction.
