The present digital era urges leadership capacity to anticipate the challenges of the times. Leadership strength is encouraging lecturers, educational personnel, and students to develop all their potential through motivation, inspiration, cooperation, and all resources to achieve goals. Meeting these goals through leadership is made possible by the current demographic bonus of the Indonesian nation, where the superior competitiveness of human resources will be the key to the nation's progress and competitiveness. The success of the learning process and the enhancement of students' problem-solving skills greatly depend on the lecturer's learning leadershipmodel. This mixed-methods study aimed to analyse the impact of a lecturer's learning leadership model on students' problem-solving skills at UIN Walisongo Semarang. The present research examined the human dimensions of the Industrial Revolution 4.0 by analysing leadership theories that focused on investigating the specific behaviour of leaders and their influences as the determinant of leadership success. Using a pre-test and post-test design, the research collected data from students in both experimental and control classes. The findings showed a significant improvement in problem-solving skills. The experimental class's mean score increased from 67.40 in the pre-test to 73.71 in the post-test, while the control class's mean score only slightly increased from 64.94 to 69.40. These results indicate that the learning leadership model effectively enhances students' problem-solving abilities.
