Abstract

This study aims to investigate the relationship between lecturer support, classroom environment, and several student psychological factors such as mathematical resilience, self-efficacy, and self-confidence. The research subjects consisted of 77 mathematics education students. The research instrument was a 38-question questionnaire. The results of data analysis showed that students gave positive responses with an average of 80.03 to lecturer support, 75.66 to the classroom environment, 79.15 to mathematical resilience, 80.57 to self-efficacy, and 75.95 to self-confidence. Furthermore, multiple linear regression analysis showed that lecturer support and classroom environment significantly influenced students' mathematical resilience by 26.7%, self-efficacy by 25.5%, and self-confidence by 30.2%. This finding indicates that the implementation of learning both in the classroom and outside the classroom is considered quite good by students. It also provides a deeper understanding of the factors that contribute to students' learning experience. The implications of this finding suggest developing strategies to improve the quality of learning by taking into account aspects of lecturer support and physical and social environmental conditions. Thus, it is expected to support students' academic achievement and personal development optimally. Keywords: Learning Environments, Lecturer Support, Mathematical Resilience, Self-Efficacy, Self-Confidence

Abstract

Tempe is a daily food of Indonesian people that is famous for its high nutritional content. One of the home industries that produce tempe in Pontianak City is Pabrik Tempe Tuan Y. In distributing tempe, Pabrik Tempe Tuan Y  applies a transshipment system with two markets as transit points, where these two markets have different locations. This study aims to determine the solution to the tempe distribution problem and determine the minimum distribution cost that can be incurred by Pabrik Tempe Tuan Y. The problem in this study is a transshipment problem with mixed constraints, where the source and destination constraints consist not only of equation signs but also inequality signs. The Max-Min method is a method for solving transshipment problems with mixed constraints that can be used to obtain optimal solutions from solving all types of transshipment problems. The transshipment problem is organized in the form of a transportation table. The table is then solved using the Max-Min method. The results showed a decrease in total transportation costs from Rp 292,136.00 to Rp 260,193.00 with a cost difference of Rp 31,943.00.  Keywords: Transportation Problem, Transshipment Problem with Mixed Constraints, Max-Min Method.

Abstract

This study aimed to determine whether the Connected Mathematics Project (CMP) instructional model enhances students' conceptual understanding compared to conventional teaching methods. Additionally, the research assessed differences in students' conceptual understanding based on their Adversity Quotient (AQ) categories: climbers, campers, and quitters. Furthermore, the study investigated whether there is an interaction between the CMP instructional model and Adversity Quotient in influencing students' conceptual understanding. The method employed was a quasi-experimental design with a posttest-only control group. The sample consisted of XI MIPA 2 as the experimental group and XI MIPA 4 as the control group. Data were collected using both test and non-test methods, and data analysis utilized a two-way analysis of variance (ANOVA). The findings revealed that the CMP instructional model significantly enhances students' conceptual understanding compared to the conventional model. Moreover, students categorized as climbers in AQ demonstrated better conceptual understanding compared to campers, while campers showed similar performance to quitters. Students with adversity quotient climbers exhibited better conceptual understanding than those with adversity quotient quitters. There was an interaction between the instructional model and adversity quotient in influencing conceptual understanding. Keywords: Adversity quotient, CMP, Conceptual understanding
