Abstract
The course of astronomy as a new course in the curriculum that must be taken by physics teacher candidate at PGRI University of Semarang. Astronomy in front of students is known as part of science-based science that gives curiosity about the science of religion and technology. Mastery of Astronomy concept of teacher candidate is analysis with the aim to take a picture of mastery of concept and process of astronomy lecture which is a new course as the base of development of astronomy learning device based on KKNI. This research method is descriptive quantitative and qualitative. Technique of collecting data is done by triangulation through analysis of test result, astronomy lecture observation, and questionnaire response of physics teacher candidate. Data analysis technique is done descriptively. The results obtained that the results of the test document analysis obtained the test instrument subjects more dominant astronomy on aspects of concept understanding, no test items that measure the realm of analysis and creation. Analysis of test results obtained that the ability of the most dominant students in the realm of knowledge and the lowest ability in the realm of application. The results of observation suggest that astronomical learning is applied by lecture, discussion and assignment methods.
