Published: March 2020

Abstract
The research aims to describe the achievement of 21st century skills such as adaptation and problem solving as part of 21st century competency in Surakarta Muhammadiyah University students to prepare of the industrial revolution 4.0. The study involved 191 prospective teacher students in Universitas Muhamamdiyah Surakarta. This study is a mixed method with exploratory sequential design. The study finds that teacher students’ adaptation capability is need much improvement. The majority of students say that they prefer to wait for someone else to start the conversations. Furthermore, they are worried to enter in the new society. In the problem-solving skills, most students focus on the solution when facing a problem. This is reasonably good, but some literature posits the finding a factor of the problem is the best way to solve a problem. Besides, there are still students who sceptic and tend to escape from the problem without any solution. This study suggests that it is prominent to include adaptation and problem-solving analysis for prospective teacher-student candidate before accepted in the university.
