This study aims to analyze the effect of learning motivation and learning environment on student academic achievement at UIN Malang, as well as explore the interaction between the two variables. The method used in this study is a quantitative approach with multiple linear regression design. Data were collected through questionnaires distributed to 200 students selected using stratified random sampling technique. The results of the analysis show that learning motivation has a significant positive influence on academic achievement with a regression coefficient of 4.674, while the learning environment also contributes positively with a coefficient of 4.649. In addition, the interaction between learning motivation and learning environment showed a significant moderating effect, albeit with an interaction regression coefficient of -0.064, which suggests that learning environment may reduce the influence of learning motivation in certain contexts. The implications of this study emphasize the importance of creating a conducive learning environment to improve student motivation and academic achievement. This research provides new insights for education managers and educators to design more effective learning strategies, as well as highlighting the need for attention to external factors that influence learning motivation. Thus, this study contributes to the development of science in the field of education, particularly in the context of higher education in Indonesia.
